ri To Advance Trade and Climate Goals, ‘Global Britain’ Must Link Them By feedproxy.google.com Published On :: Thu, 19 Mar 2020 17:12:54 +0000 19 March 2020 Carolyn Deere Birkbeck Associate Fellow, Global Economy and Finance Programme, and Hoffmann Centre for Sustainable Resource Economy @carolyndeere LinkedIn Google Scholar Dr Emily Jones Associate Professor, Blavatnik School of Government Dr Thomas Hale Associate Professor, Blavatnik School of Government COVID-19 is a sharp reminder of why trade policy matters. As the UK works to forge new trade deals, it must align its trade policy agenda with its climate ambition. 2020-03-19-Boris-Johnson-COP26.jpg Boris Johnson at the launch of the UK-hosted COP26 UN Climate Summit at the Science Museum, London on February 4, 2020. Photo by Jeremy Selwyn - WPA Pool/Getty Images. COVID-19 is a sharp reminder of why trade and climate policy matters. How can governments maintain access to critical goods and services, and ensure global supply chains function in times of crisis?The timing of many trade negotiations is now increasingly uncertain, as are the UK’s plans to host COP26 in November. Policy work continues, however, and the EU has released its draft negotiating text for the new UK-EU trade deal, which includes a sub-chapter specifically devoted to climate. This is a timely reminder both of the pressing need for the UK to integrate its trade and climate policymaking and to use the current crisis-induced breathing space in international negotiations - however limited - to catch up on both strategy and priorities on this critical policy intersection.The UK government has moved fast to reset its external trade relations post-Brexit. In the past month it formally launched bilateral negotiations with the EU and took up a seat at the World Trade Organization (WTO) as an independent member. Until the COVID-19 crisis hit, negotiations were also poised to start with the US.The UK is also in the climate spotlight as host of COP26, the most important international climate negotiation since Paris in 2015, which presents a vital opportunity for the government to show leadership by aligning its trade agenda with its climate and sustainability commitments in bold new ways.Not just an empty aspirationThis would send a signal that ‘Global Britain’ is not just an empty aspiration, but a concrete commitment to lead.Not only is concerted action on the climate crisis a central priority for UK citizens, a growing and increasingly vocal group of UK businesses committed to decarbonization are calling on the government to secure a more transparent and predictable international market place that supports climate action by business.With COP26, the UK has a unique responsibility to push governments to ratchet up ambition in the national contributions to climate action – and to promote coherence between climate ambition and wider economic policymaking, including on trade. If Britain really wants to lead, here are some concrete actions it should take.At the national level, the UK can pioneer new ways to put environmental sustainability – and climate action in particular - at the heart of its trade agenda. Achieving the government’s ambitious Clean Growth Strategy - which seeks to make the UK the global leader in a range of industries including electric cars and offshore wind – should be a central objective of UK trade policy.The UK should re-orient trade policy frameworks to incentivize the shift toward a more circular and net zero global economy. And all elements of UK trade policy could be assessed against environmental objectives - for example, their contribution to phasing out fossil fuels, helping to reverse overexploitation of natural resources, and support for sustainable agriculture and biodiversity.In its bilateral and regional trade negotiations, the UK can and should advance its environment, climate and trade goals in tandem, and implementation of the Paris Agreement must be a core objective of the UK trade strategy.A core issue for the UK is how to ensure that efforts to decarbonise the economy are not undercut by imports from high-carbon producers. Here, a ‘border carbon adjustment (BCA)’ - effectively a tax on the climate pollution of imports - would support UK climate goals. The EU draft negotiating text released yesterday put the issue of BCAs front and centre, making crystal clear that the intersection of climate, environment and trade policy goals will be a central issue for UK-EU trade negotiations.Even with the United States, a trade deal can and should still be seized as a way to incentivize the shift toward a net zero and more circular economy. At the multilateral level, as a new independent WTO member, the UK has an opportunity to help build a forward-looking climate and trade agenda.The UK could help foster dialogue, research and action on a cluster of ‘climate and trade’ issues that warrant more focused attention at the WTO. These include the design of carbon pricing policies at the border that are transparent, fair and support a just transition; proposals for a climate waiver for WTO rules; and identification of ways multilateral trade cooperation could promote a zero carbon and more circular global economy. To help nudge multilateral discussion along, the UK could also ask to join a critical ‘path finder’ effort by six governments, led by New Zealand, to pursue an agreement on climate change, trade and sustainability (ACCTS). This group aims to find ways forward on three central trade and climate issues: removing fossil fuel subsidies, climate-related labelling, and promoting trade in climate-friendly goods and services.At present, the complex challenges at the intersection of climate, trade and development policy are too often used to defer or side-step issues deemed ‘too hard’ or ‘too sensitive’ to tackle. The UK could help here by working to ensure multilateral climate and trade initiatives share adjustment burdens, recognise the historical responsibility of developed countries, and do not unfairly disadvantage developing countries - especially the least developed.Many developing countries are keen to promote climate-friendly exports as part of wider export diversification strategies and want to reap greater returns from greener global value chains. Further, small island states and least-developed countries – many of which are Commonwealth members – that are especially vulnerable to the impacts of climate change and natural disasters, need support to adapt in the face of trade shocks and to build climate-resilient, trade-related infrastructure and export sectors.As an immediate next step, the UK should actively support the growing number of WTO members in favour of a WTO Ministerial Statement on environmental sustainability and trade. It should work with its key trading partners in the Commonwealth and beyond to ensure the agenda is inclusive, supports achievement of the UN Sustainable Development Goals (SDGs) and helps developing countries benefit from a more environmentally sustainable global economy.As the UK prepares to host COP26, negotiates deals with the EU and US, and prepares for its first WTO Ministerial meeting as an independent member, it must show it can lead the way nationally, bilaterally, and multilaterally. And to ensure the government acts, greater engagement from the UK’s business, civil society and research sectors is critical – we need all hands on deck to forge and promote concrete proposals for aligning UK trade policy with the climate ambition our world needs.

ri A comprehensive evaluation of a typical plant telomeric G-quadruplex (G4) DNA reveals the dynamics of G4 formation, rearrangement, and unfolding [Plant Biology] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Telomeres are specific nucleoprotein structures that are located at the ends of linear eukaryotic chromosomes and play crucial roles in genomic stability. Telomere DNA consists of simple repeats of a short G-rich sequence: TTAGGG in mammals and TTTAGGG in most plants. In recent years, the mammalian telomeric G-rich repeats have been shown to form G-quadruplex (G4) structures, which are crucial for modulating telomere functions. Surprisingly, even though plant telomeres are essential for plant growth, development, and environmental adaptions, only few reports exist on plant telomeric G4 DNA (pTG4). Here, using bulk and single-molecule assays, including CD spectroscopy, and single-molecule FRET approaches, we comprehensively characterized the structure and dynamics of a typical plant telomeric sequence, d[GGG(TTTAGGG)3]. We found that this sequence can fold into mixed G4s in potassium, including parallel and antiparallel structures. We also directly detected intermediate dynamic transitions, including G-hairpin, parallel G-triplex, and antiparallel G-triplex structures. Moreover, we observed that pTG4 is unfolded by the AtRecQ2 helicase but not by AtRecQ3. The results of our work shed light on our understanding about the existence, topological structures, stability, intermediates, unwinding, and functions of pTG4. Full Article
ri Spectral and photochemical diversity of tandem cysteine cyanobacterial phytochromes [Plant Biology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The atypical trichromatic cyanobacterial phytochrome NpTP1 from Nostoc punctiforme ATCC 29133 is a linear tetrapyrrole (bilin)-binding photoreceptor protein that possesses tandem-cysteine residues responsible for shifting its light-sensing maximum to the violet spectral region. Using bioinformatics and phylogenetic analyses, here we established that tandem-cysteine cyanobacterial phytochromes (TCCPs) compose a well-supported monophyletic phytochrome lineage distinct from prototypical red/far-red cyanobacterial phytochromes. To investigate the light-sensing diversity of this family, we compared the spectroscopic properties of NpTP1 (here renamed NpTCCP) with those of three phylogenetically diverged TCCPs identified in the draft genomes of Tolypothrix sp. PCC7910, Scytonema sp. PCC10023, and Gloeocapsa sp. PCC7513. Recombinant photosensory core modules of ToTCCP, ScTCCP, and GlTCCP exhibited violet-blue–absorbing dark-states consistent with dual thioether-linked phycocyanobilin (PCB) chromophores. Photoexcitation generated singly-linked photoproduct mixtures with variable ratios of yellow-orange and red-absorbing species. The photoproduct ratio was strongly influenced by pH and by mutagenesis of TCCP- and phytochrome-specific signature residues. Our experiments support the conclusion that both photoproduct species possess protonated 15E bilin chromophores, but differ in the ionization state of the noncanonical “second” cysteine sulfhydryl group. We found that the ionization state of this and other residues influences subsequent conformational change and downstream signal transmission. We also show that tandem-cysteine phytochromes present in eukaryotes possess similar amino acid substitutions within their chromophore-binding pocket, which tune their spectral properties in an analogous fashion. Taken together, our findings provide a roadmap for tailoring the wavelength specificity of plant phytochromes to optimize plant performance in diverse natural and artificial light environments.

ri A peroxisome deficiency-induced reductive cytosol state up-regulates the brain-derived neurotrophic factor pathway [Metabolism] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 The peroxisome is a subcellular organelle that functions in essential metabolic pathways, including biosynthesis of plasmalogens, fatty acid β-oxidation of very-long-chain fatty acids, and degradation of hydrogen peroxide. Peroxisome biogenesis disorders (PBDs) manifest as severe dysfunction in multiple organs, including the central nervous system (CNS), but the pathogenic mechanisms in PBDs are largely unknown. Because CNS integrity is coordinately established and maintained by neural cell interactions, we here investigated whether cell-cell communication is impaired and responsible for the neurological defects associated with PBDs. Results from a noncontact co-culture system consisting of primary hippocampal neurons with glial cells revealed that a peroxisome-deficient astrocytic cell line secretes increased levels of brain-derived neurotrophic factor (BDNF), resulting in axonal branching of the neurons. Of note, the BDNF expression in astrocytes was not affected by defects in plasmalogen biosynthesis and peroxisomal fatty acid β-oxidation in the astrocytes. Instead, we found that cytosolic reductive states caused by a mislocalized catalase in the peroxisome-deficient cells induce the elevation in BDNF secretion. Our results suggest that peroxisome deficiency dysregulates neuronal axogenesis by causing a cytosolic reductive state in astrocytes. We conclude that astrocytic peroxisomes regulate BDNF expression and thereby support neuronal integrity and function. Full Article
ri Heterotrimeric Gq proteins as therapeutic targets? [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Heterotrimeric G proteins are the core upstream elements that transduce and amplify the cellular signals from G protein–coupled receptors (GPCRs) to intracellular effectors. GPCRs are the largest family of membrane proteins encoded in the human genome and are the targets of about one-third of prescription medicines. However, to date, no single therapeutic agent exerts its effects via perturbing heterotrimeric G protein function, despite a plethora of evidence linking G protein malfunction to human disease. Several recent studies have brought to light that the Gq family–specific inhibitor FR900359 (FR) is unexpectedly efficacious in silencing the signaling of Gq oncoproteins, mutant Gq variants that mostly exist in the active state. These data not only raise the hope that researchers working in drug discovery may be able to potentially strike Gq oncoproteins from the list of undruggable targets, but also raise questions as to how FR achieves its therapeutic effect. Here, we place emphasis on these recent studies and explain why they expand our pharmacological armamentarium for targeting Gq protein oncogenes as well as broaden our mechanistic understanding of Gq protein oncogene function. We also highlight how this novel insight impacts the significance and utility of using G(q) proteins as targets in drug discovery efforts. Full Article
ri N{alpha}-Acetylation of the virulence factor EsxA is required for mycobacterial cytosolic translocation and virulence [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 The Mycobacterium tuberculosis virulence factor EsxA and its chaperone EsxB are secreted as a heterodimer (EsxA:B) and are crucial for mycobacterial escape from phagosomes and cytosolic translocation. Current findings support the idea that for EsxA to interact with host membranes, EsxA must dissociate from EsxB at low pH. However, the molecular mechanism by which the EsxA:B heterodimer separates is not clear. In the present study, using liposome-leakage and cytotoxicity assays, LC-MS/MS–based proteomics, and CCF-4 FRET analysis, we obtained evidence that the Nα-acetylation of the Thr-2 residue on EsxA, a post-translational modification that is present in mycobacteria but absent in Escherichia coli, is required for the EsxA:B separation. Substitutions at Thr-2 that precluded Nα-acetylation inhibited the heterodimer separation and hence prevented EsxA from interacting with the host membrane, resulting in attenuated mycobacterial cytosolic translocation and virulence. Molecular dynamics simulations revealed that at low pH, the Nα-acetylated Thr-2 makes direct and frequent “bind-and-release” contacts with EsxB, which generates a force that pulls EsxB away from EsxA. In summary, our findings provide evidence that the Nα-acetylation at Thr-2 of EsxA facilitates dissociation of the EsxA:B heterodimer required for EsxA membrane permeabilization and mycobacterial cytosolic translocation and virulence.

ri Modification of a PE/PPE substrate pair reroutes an Esx substrate pair from the mycobacterial ESX-1 type VII secretion system to the ESX-5 system [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 Bacterial type VII secretion systems secrete a wide range of extracellular proteins that play important roles in bacterial viability and in interactions of pathogenic mycobacteria with their hosts. Mycobacterial type VII secretion systems consist of five subtypes, ESX-1–5, and have four substrate classes, namely, Esx, PE, PPE, and Esp proteins. At least some of these substrates are secreted as heterodimers. Each ESX system mediates the secretion of a specific set of Esx, PE, and PPE proteins, raising the question of how these substrates are recognized in a system-specific fashion. For the PE/PPE heterodimers, it has been shown that they interact with their cognate EspG chaperone and that this chaperone determines the designated secretion pathway. However, both structural and pulldown analyses have suggested that EspG cannot interact with the Esx proteins. Therefore, the determining factor for system specificity of the Esx proteins remains unknown. Here, we investigated the secretion specificity of the ESX-1 substrate pair EsxB_1/EsxA_1 in Mycobacterium marinum. Although this substrate pair was hardly secreted when homologously expressed, it was secreted when co-expressed together with the PE35/PPE68_1 pair, indicating that this pair could stimulate secretion of the EsxB_1/EsxA_1 pair. Surprisingly, co-expression of EsxB_1/EsxA_1 with a modified PE35/PPE68_1 version that carried the EspG5 chaperone-binding domain, previously shown to redirect this substrate pair to the ESX-5 system, also resulted in redirection and co-secretion of the Esx pair via ESX-5. Our results suggest a secretion model in which PE35/PPE68_1 determines the system-specific secretion of EsxB_1/EsxA_1. Full Article
ri Pro-515 of the dynamin-like GTPase MxB contributes to HIV-1 inhibition by regulating MxB oligomerization and binding to HIV-1 capsid [Microbiology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Interferon-regulated myxovirus resistance protein B (MxB) is an interferon-induced GTPase belonging to the dynamin superfamily. It inhibits infection with a wide range of different viruses, including HIV-1, by impairing viral DNA entry into the nucleus. Unlike the related antiviral GTPase MxA, MxB possesses an N-terminal region that contains a nuclear localization signal and is crucial for inhibiting HIV-1. Because MxB previously has been shown to reside in both the nuclear envelope and the cytoplasm, here we used bioinformatics and biochemical approaches to identify a nuclear export signal (NES) responsible for MxB's cytoplasmic location. Using the online computational tool LocNES (Locating Nuclear Export Signals or NESs), we identified five putative NES candidates in MxB and investigated whether their deletion caused nuclear localization of MxB. Our results revealed that none of the five deletion variants relocates to the nucleus, suggesting that these five predicted NES sequences do not confer NES activity. Interestingly, deletion of one sequence, encompassing amino acids 505–527, abrogated the anti-HIV-1 activity of MxB. Further mutation experiments disclosed that amino acids 515–519, and Pro-515 in particular, regulate MxB oligomerization and its binding to HIV-1 capsid, thereby playing an important role in MxB-mediated restriction of HIV-1 infection. In summary, our results indicate that none of the five predicted NES sequences in MxB appears to be required for its nuclear export. Our findings also reveal several residues in MxB, including Pro-515, critical for its oligomerization and anti-HIV-1 function. Full Article
ri A neuroglobin-based high-affinity ligand trap reverses carbon monoxide-induced mitochondrial poisoning [Molecular Biophysics] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Carbon monoxide (CO) remains the most common cause of human poisoning. The consequences of CO poisoning include cardiac dysfunction, brain injury, and death. CO causes toxicity by binding to hemoglobin and by inhibiting mitochondrial cytochrome c oxidase (CcO), thereby decreasing oxygen delivery and inhibiting oxidative phosphorylation. We have recently developed a CO antidote based on human neuroglobin (Ngb-H64Q-CCC). This molecule enhances clearance of CO from red blood cells in vitro and in vivo. Herein, we tested whether Ngb-H64Q-CCC can also scavenge CO from CcO and attenuate CO-induced inhibition of mitochondrial respiration. Heart tissue from mice exposed to 3% CO exhibited a 42 ± 19% reduction in tissue respiration rate and a 33 ± 38% reduction in CcO activity compared with unexposed mice. Intravenous infusion of Ngb-H64Q-CCC restored respiration rates to that of control mice correlating with higher electron transport chain CcO activity in Ngb-H64Q-CCC–treated compared with PBS-treated, CO-poisoned mice. Further, using a Clark-type oxygen electrode, we measured isolated rat liver mitochondrial respiration in the presence and absence of saturating solutions of CO (160 μm) and nitric oxide (100 μm). Both CO and NO inhibited respiration, and treatment with Ngb-H64Q-CCC (100 and 50 μm, respectively) significantly reversed this inhibition. These results suggest that Ngb-H64Q-CCC mitigates CO toxicity by scavenging CO from carboxyhemoglobin, improving systemic oxygen delivery and reversing the inhibitory effects of CO on mitochondria. We conclude that Ngb-H64Q-CCC or other CO scavengers demonstrate potential as antidotes that reverse the clinical and molecular effects of CO poisoning. Full Article
ri Reactive dicarbonyl compounds cause Calcitonin Gene-Related Peptide release and synergize with inflammatory conditions in mouse skin and peritoneum [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The plasmas of diabetic or uremic patients and of those receiving peritoneal dialysis treatment have increased levels of the glucose-derived dicarbonyl metabolites like methylglyoxal (MGO), glyoxal (GO), and 3-deoxyglucosone (3-DG). The elevated dicarbonyl levels can contribute to the development of painful neuropathies. Here, we used stimulated immunoreactive Calcitonin Gene–Related Peptide (iCGRP) release as a measure of nociceptor activation, and we found that each dicarbonyl metabolite induces a concentration-, TRPA1-, and Ca2+-dependent iCGRP release. MGO, GO, and 3-DG were about equally potent in the millimolar range. We hypothesized that another dicarbonyl, 3,4-dideoxyglucosone-3-ene (3,4-DGE), which is present in peritoneal dialysis (PD) solutions after heat sterilization, activates nociceptors. We also showed that at body temperatures 3,4-DGE is formed from 3-DG and that concentrations of 3,4-DGE in the micromolar range effectively induced iCGRP release from isolated murine skin. In a novel preparation of the isolated parietal peritoneum PD fluid or 3,4-DGE alone, at concentrations found in PD solutions, stimulated iCGRP release. We also tested whether inflammatory tissue conditions synergize with dicarbonyls to induce iCGRP release from isolated skin. Application of MGO together with bradykinin or prostaglandin E2 resulted in an overadditive effect on iCGRP release, whereas MGO applied at a pH of 5.2 resulted in reduced release, probably due to an MGO-mediated inhibition of transient receptor potential (TRP) V1 receptors. These results indicate that several reactive dicarbonyls activate nociceptors and potentiate inflammatory mediators. Our findings underline the roles of dicarbonyls and TRPA1 receptors in causing pain during diabetes or renal disease. Full Article
ri Inhibition of the polyamine synthesis enzyme ornithine decarboxylase sensitizes triple-negative breast cancer cells to cytotoxic chemotherapy [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Treatment of patients with triple-negative breast cancer (TNBC) is limited by a lack of effective molecular therapies targeting this disease. Recent studies have identified metabolic alterations in cancer cells that can be targeted to improve responses to standard-of-care chemotherapy regimens. Using MDA-MB-468 and SUM-159PT TNBC cells, along with LC-MS/MS and HPLC metabolomics profiling, we found here that exposure of TNBC cells to the cytotoxic chemotherapy drugs cisplatin and doxorubicin alter arginine and polyamine metabolites. This alteration was because of a reduction in the levels and activity of a rate-limiting polyamine biosynthetic enzyme, ornithine decarboxylase (ODC). Using gene silencing and inhibitor treatments, we determined that the reduction in ODC was mediated by its negative regulator antizyme, targeting ODC to the proteasome for degradation. Treatment with the ODC inhibitor difluoromethylornithine (DFMO) sensitized TNBC cells to chemotherapy, but this was not observed in receptor-positive breast cancer cells. Moreover, TNBC cell lines had greater sensitivity to single-agent DFMO, and ODC levels were elevated in TNBC patient samples. The alterations in polyamine metabolism in response to chemotherapy, as well as DFMO-induced preferential sensitization of TNBC cells to chemotherapy, reported here suggest that ODC may be a targetable metabolic vulnerability in TNBC.

ri Five Lessons From the New Arab Uprisings By feedproxy.google.com Published On :: Tue, 12 Nov 2019 09:11:56 +0000 12 November 2019 Dr Georges Fahmi Associate Fellow, Middle East and North Africa Programme @GeorgesFahmi Georges Fahmi examines how protesters across the region have adapted their tactics after the experiences of the Arab Spring. 2019-11-12-Lebanon.jpg The second wave of Arab uprisings that started in Sudan in December last year and extended to Algeria, Lebanon and Iraq this year have built on past experiences of political transitions during the Arab Spring, both its mistakes and achievements. Protesters from this new wave have already learned five lessons from previous transitions.The first lesson is that toppling the head of a regime does not mean that the political regime has fallen. In Tahrir Square on 11 February 2011, Egyptian protesters celebrated the decision of Hosni Mubarak to step down and left the square, thinking his resignation was enough to allow a democratic transition to take place. In contrast, in Sudan and Algeria, protesters continued to demonstrate after the resignation of Abdelaziz Bouteflika and the military-led ousting of Omar al-Bashir.Protesters understood the lesson that the regime is found not only in the head of the state, but rather in the rules that govern the political sphere. By extension, political change requires changing the rules, not just the names of those in charge of implementing them.The second lesson is that resorting to violence is the fastest way to end any hope for democratic change. Protesters who decided to take up arms offered their regimes the chance to reframe the political uprisings as civil war, as was the case in Syria. Even when armed groups manage to bring down the regime, their presence endangers the transitional phase afterwards, as is the case in Libya.Although protesters in Sudan and Iraq have been faced with government violence and repression, they have insisted on their non-violent approach. In Sudan, the protesters responded to the massacre outside of the General Command of the Armed Forces on 3 June by organizing a mass demonstration on 30 June, which put pressure on the military to resume talks with the revolutionary forces. The third lesson is that once the old regime has fallen, the transition period must be a collective decision-making process in which the opposition has, at least, veto power. The example of Tunisia after 2011 is a case in point. The Higher Authority for Realization of the Goals of the Revolution, Political Reform and Democratic Transition, which formulated the planned course of the transition, included representatives from across the political spectrum and civil society.Although the military forces in Algeria and Sudan will not cease to play a political role any time soon, this does not have to mean exerting complete control over the transitional period. Sudan could offer a positive example in this regard, if it succeeds in implementing a power-sharing deal according to which a joint civilian-military sovereign council will govern Sudan during the transitional period.The fourth lesson is that political transitions should achieve agreement on the rules of the game before proceeding to elections. In Egypt after 2011, rushed elections served to divide the political opposition and dramatically increase polarization in society. In this second wave, protesters have perceived elections as a trap which enable old regimes to reproduce themselves with new names.In both Algeria and Sudan, protesters have resisted attempts by the military to hold elections as soon as possible. In Sudan, the agreement between the revolutionary forces and the military council postponed the elections until after the end of a three-year transitional period of technocratic rule. In Algeria, protesters are taking to the streets every Friday to demonstrate against the authorities’ decision to hold presidential elections in December.The fifth and final lesson is that the call for change in the region goes beyond electoral democracy and extends to deep socioeconomic reforms. Iraq and Lebanon show this clearly: relatively free and fair elections have already been held but have served only to reinforce corrupt sectarian regimes.According to the fifth wave of the Arab Barometer, the economic situation and corruption are perceived as the main challenge for Algerians (62.2%), Sudanese (67.8%), Lebanese (57.9%), and Iraqis (50.2%), while democracy is perceived as the main challenge for only 2.3%, 3.9%, 5% and 1.4% respectively. The experience of the Arab Spring has shown people that democratic measures are only a means to an end.Unlike in 2011, when the Arab Spring revolts enjoyed broad international support, this second wave is taking place in a hostile environment, with stronger Russian and Iranian presences in the region and an indifferent international climate. But where protesters have the advantage is in experience, and across the region they are clearly adapting their tactics to lessons learned from the early part of the decade. Full Article

ri Synergy in North Africa: Furthering Cooperation By feedproxy.google.com Published On :: Mon, 20 Jan 2020 15:57:54 +0000 21 January 2020 Discussions of North African integration have evoked ideas of a shared identity and a common destiny in the region. However, recent attempts to build regional blocs in North Africa have been unsuccessful. This paper examines the benefits of a ‘synergistic’ approach to North African cooperation.

Photo: Getty Images. SummaryNorth African integration is not a new idea. However, countries in the region have so far struggled to form a cohesive bloc with deep political, economic and social ties. Political instability has effectively deprioritized North African integration. A focus on thematic (political, economic and security) ‘synergies’ may provide a better framework for cooperation than seeking opportunities for all-encompassing ‘deep’ and ‘comprehensive’ integration.Governments of North Africa dedicate considerable resources to domestic security. Much of their efforts are conducted at the national-level and directed towards threats from terrorists, insurgents and militias. Improved security cooperation would achieve better outcomes and economies of scale, including efforts to tackle human trafficking.A new generation of jihadis has emerged in North Africa since 2011. Nearly 27 per cent of the 30,000 fighters who travelled to Syria are from the Maghreb. While government counterterrorism operations have been effective, countries have failed to address the root causes of radicalization.Border economies have suffered as a consequence of a security focus on terrorism and smuggling, which has rendered many previously accepted cross-border trade activities illegal. States have struggled to provide alternative livelihoods for those who have lost this source of income. Border forces tend to lack the right combination of capacity, training and equipment to secure borders and often resort to heavy-handed tactics.New thinking is required to develop a more human-centric and proactive approach to migration issues in the region, which continues to witness huge flows of migrants. The migration policy of Morocco, introduced through legislation in 2014, could be a model for North Africa.The countries of North Africa have varying economic profiles, ranging from economically diverse Morocco to oil-and-gas-dependant Libya. However, they all face similar challenges including unemployment (particularly among the young), poor public-service delivery, low FDI levels, an oversized public sector, ineffective tax collection, and high informality.Fostering entrepreneurship and the development of small and medium-sized enterprises (SMEs) are priorities for North African countries, particularly regarding job creation. Regulatory cooperation – such as harmonizing SME definitions, legislation and support institutions – across North Africa is an obvious area where further integration would encourage the development of start-ups and small businesses.With the advent of the fourth industrial revolution, North African governments must address their technological gaps and work to improve public–private cooperation. In some sectors, such as the fintech industry, North African countries can build upon nascent synergies that have developed organically, such as those of start-up incubators and angel investors that work across the region.Renewables, particularly solar energy production, are a promising development for North Africa. While regional initiatives, such as Desertec, have stalled due to political differences between countries, the sector has witnessed exponential growth in Tunisia, Egypt and Morocco, where the involvement of the private sector has proved successful.

Only a few decades ago, the country was one of the most fertile in the region, with two major rivers flowing through it. Today, national and transboundary pollution, mismanagement, and debilitating cycles of conflict have contributed to a situation where only half of current water needs are being met, and where an 80% reduction in the flow of water down the Tigris and Euphrates rivers has led to the loss of millions of acres of formerly productive land and the displacement of rural communities.Water scarcity can be a driver of violence and conflict. Tribal conflicts over water sources have erupted sporadically in the south and the contamination of municipal water which led to the hospitalization of some 118,000 citizens was a trigger for the large-scale protests in Basra in late 2018. Without concerted action by national and local governments, companies and international agencies, the situation will only worsen as higher temperatures and reduced rainfall drive rural-to-urban migration and increase the risk of drought, food insecurity and water-related diseases.At this roundtable, part of the Chatham House Iraq Initiative, experts will discuss the domestic, regional and international factors that continue to exacerbate the water crisis in Iraq, and propose solutions, including technical innovation, public sector capacity-building and greater international cooperation, that might contribute to effective state-building, build resilience to the effects of climate change and reduce the risk of further conflict.

ri Can Morocco Effectively Handle the COVID-19 Crisis? By feedproxy.google.com Published On :: Mon, 06 Apr 2020 09:10:24 +0000 6 April 2020 Dr Mohammed Masbah Associate Fellow, Middle East and North Africa Programme @MasbahMohammed LinkedIn Google Scholar Anna Jacobs Senior Research Assistant, Brookings Doha Center The Moroccan government is capitalizing on a burst of unity, social solidarity and public support in the face of a crisis. However, if it fails to effectively mitigate the public health and economic impacts of the COVID-19 pandemic, this spirit of solidarity and cooperation will not last long. GettyImages-1208907580.jpg A general view of empty stores during curfew as a precaution against the new type of coronavirus (COVID-19) in Rabat, Morocco on 1 April 2020. Photo by Jalal Morchidi/Anadolu Agency via Getty Images. In Morocco, the COVID-19 pandemic has increased public trust in government, but people still have doubts about the effectiveness of the healthcare system. According to a recent study conducted by the Moroccan Institute for Policy Analysis (MIPA), the majority of Moroccans surveyed are generally satisfied with the measures taken by the government to battle the coronavirus. However, the same survey also shows that Moroccans do not have confidence in the healthcare sector’s ability to respond to this pandemic.The positive perceptions of the government’s response can be explained by the swift and strict measures enacted. King Mohammed VI held a high-level meeting with the prime minister, the minister of health, and top security officials on 17 March and a few days later, on 20 March, the Moroccan government declared a state of health emergency and began to implement aggressive measures to contain the virus.This has included closing airports, schools, mosques, cafés and shops – with the exception of food markets – preventing large gatherings, as well as strict guidelines to ensure social distancing. As of 2 April, nearly 5000 people have been arrested for violating the state of health emergency.In order to address urgent medical needs and to mitigate the economic impact of the pandemic, the King ordered the creation of an emergency fund, raising more than 32.7 billion Moroccan Dirhams ($3.2 billion). The Ministry of Finance will begin to make cash transfers to vulnerable citizens, and especially those who have lost their jobs. However, the stipulations surrounding these cash transfers will be decided in the coming weeks.Updates about the virus are communicated daily by the Ministry of Health, despite growing criticism of its communication strategy. As of 4 April, Moroccan authorities have confirmed 883 cases and 58 deaths.Call for national unityIn times like these, there is a call for unity in the face of a national and global crisis, and opposition groups such as Adl wal Ihssan and Rif activists have expressed their support for government measures and have encouraged people to follow the new guidelines and restrictions. However, despite calls to release political prisoners, Moroccan authorities have not indicated that they will do so. This is a missed opportunity vis-à-vis the opposition because it could have served as a way to further strengthen national unity during the crisis.These are all promising signs and point to what is likely to be a short-term burst in unity and institutional trust. However, the institutional weaknesses in governance and the healthcare system have not disappeared, which is why this increase in institutional trust should be taken with a grain of salt.Public trust issuesThis pandemic poses tremendous challenges for governments across the globe, and this holds especially true for states in the Middle East and North Africa region, where citizens do not approve of government performance and do not trust key state institutions. The 2019 Arab Barometer survey found that Moroccans do not trust most of the country’s political institutions (notably the parliament and the Council of Ministers) and the level of satisfaction with the government’s performance remains extremely low.On the public health front, as shown in two of MIPA’s recent surveys, trust in the healthcare system is also very low. Around three-quarters of those surveyed do not trust Moroccan hospitals, highlighting the acute structural problems in the healthcare system. In fact, there is a stark divide between private and public healthcare, as well as a huge gap in access to healthcare facilities between urban and rural areas. Most of the country’s hospitals and doctors are located in major urban areas and the only three laboratories with capabilities for COVID-19 testing are located in Rabat and Casablanca, but even there, testing capacity is very limited.Similar to other countries, there could be a major shortage of doctors and medical equipment throughout Morocco. So far, the Ministry of Finance has said that 2 billion dirhams of the emergency fund will go towards purchasing medical equipment such as beds, ventilators, tests, prevention kits and radiology equipment, but the timeline remains unclear.A vulnerable economyThere is significant concern about the medium- and long-term economic impact of the virus. Two of the country’s key economic sectors have already been hit hard: agriculture and tourism. The agricultural sector was already struggling due to the impact of drought, while the coronavirus pandemic is likely to impact Morocco’s tourism industry not just this year, but well into 2021. In terms of government response, the emergency fund is a strong start, but questions surrounding the management of these funds have already been raised.The most vulnerable parts of the population have been affected by the economic crisis because of the country’s bulging informal sector – in which most people work - and a very weak private sector. In fact, two-thirds of the workforce are not covered by a pension plan, almost half of the working population does not currently benefit from medical coverage and there is no social care system for vulnerable parts of the population. As of 1 April, more than 700,000 workers have lost their jobs.Moving forward?Even if public perceptions of the government’s response are positive at the moment, this is most likely a short-term surge that should not be taken for granted. Despite the efforts made by the government, Morocco’s health system is not equipped to handle this crisis. Even with the new measures that have been implemented, if the spread of the virus gets out of control, more funds, more doctors, and more equipment will be needed. Given the structural weaknesses of the healthcare system, this will be an uphill battle.Moreover, even if the government manages to mitigate the public health impact, the economic consequences will be dire—especially in the tourism industry—and will severely hurt those workers in the informal sector who are living without a safety net. In Morocco, this category represents most of the working population.This crisis highlights that the Moroccan government must urgently tackle its large portfolio of unfinished reforms, notably in healthcare, the economy, and labour rights. So far, the government is capitalizing on the spirit of unity, social solidarity and public support. The future trajectory of the pandemic and the effectiveness of governance will determine if this spirit of solidarity will last. If the government fails to effectively mitigate the public health and economic impacts of this pandemic, this solidarity and cooperation will not last long. Full Article
ri Same Old Politics Will Not Solve Iraq Water Crisis By feedproxy.google.com Published On :: Wed, 15 Apr 2020 15:36:21 +0000 15 April 2020 Georgia Cooke Project Manager, Middle East and North Africa Programme Dr Renad Mansour Senior Research Fellow, Middle East and North Africa Programme; Project Director, Iraq Initiative @renadmansour Glada Lahn Senior Research Fellow, Energy, Environment and Resources Programme @Glada_Lahn Addressing Iraq’s water crisis should be a priority for any incoming prime minister as it is damaging the country’s attempts to rebuild. But successive governments have allowed the problem to fester. 2020-04-15-Iraq-Water Punting in the marshes south of the Iraqi city of Ammarah. Photo by Ghaith Abdul-Ahad/Getty Images. Historically, Iraq lay claim to one of the most abundant water supplies in the Middle East. But the flow of the Tigris and Euphrates rivers has reduced by up to 40% since the 1970s, due in part to the actions of neighbouring countries, in particular Turkey, upstream.Rising temperatures and reduced rainfall due to climate change are also negatively impacting Iraq’s water reserves. Evaporation from dams and reservoirs is estimated to lose the country up to 8 billion cubic metres of water every year.A threat to peace and stabilityShortages have dried up previously fertile land, increasing poverty in agricultural areas. Shortages have also served to fuel conflict: communities faced with successive droughts and government inertia proved to be easy targets for ISIS recruiters, who lured farmers into joining them by offering money and food to feed their families. Economic hardship for those whose livelihoods relied upon river water has also driven rural to urban migration, putting significant strain on already over-populated towns and cities, exacerbating housing, job and electricity shortages, and widening the gap between haves and have-nots.But scarcity isn’t the most crucial element of Iraq’s water crisis – contamination is. Decades of local government mismanagement, corrupt practices and a lack of regulation of dumping (it is estimated up to 70% of Iraq’s industrial waste is dumped directly into water) has left approximately three in every five citizens without a reliable source of potable water.In 2018, 118,000 residents of Basra province were hospitalised with symptoms brought on by drinking contaminated water, which not only put a spotlight on the inadequacies of a crumbling healthcare system but sparked mass protests and a subsequent violent crackdown.The water crisis is also undermining the stability of the country’s federal governance model, by occasionally sparking disputes between Baghdad and the Kurdistan Regional Government, as well as between governorates in the south.The crisis is both a symptom and a cause of poor governance. Iraq is stuck in a cycle whereby government inaction causes shortages and contamination, which result in economic losses, reduced food supply, increased prices and widespread poor health. This in turn leads to increasing levels of poverty, higher demand on services and civil unrest, increasing the pressure on a weak, dysfunctional system of government.What can be done?The first priority should be modernising existing water-management infrastructure - a relic of a time when the problem was an excess rather than a shortage of water (the last time Iraq’s flood defences were required was 1968). Bureaucratic hurdles, widespread corruption and an endless cycle of other crises taking precedent prevent good initiatives from being implemented or scaled up.Diversifying energy sources to improve provision is crucial. Baghdad has a sewage treatment plant that originally ran on its own electricity source, but this capacity was destroyed in 1991 and was never replaced. The city continues to suffer from dangerous levels of water pollution because the electricity supply from the grid is insufficient to power the plant. Solar energy has great potential in sun-drenched Iraq to bridge the gaping hole in energy provision, but successive governments have chosen to focus on fossil fuels rather than promoting investment to grow the renewables sector.Heightened tension with upstream Turkey could turn water into another cause of regional conflict. But, if approached differently, collaboration between Iraq and its neighbour could foster regional harmony.Turkey’s elevated geography and cooler climate mean its water reserves suffer 75% less evaporation than Iraq’s. Given that Turkey’s top energy priority is the diversification of its supply of imported hydrocarbons, a win-win deal could see Turkey exchange access to its water-management infrastructure for delivery of reduced cost energy supplies from Iraq.German-French cooperation on coal and steel in the 1950s and the evolution of economic integration that followed might provide a model for how bilateral cooperation over one issue could result in cooperation with other regional players (in this case Iran and Syria) on a range of other issues. This kind of model would need to consider the future of energy, whereby oil and gas would be replaced by solar-power exports.These solutions have been open to policymakers for years and yet they have taken little tangible action. While there are leaders and bureaucrats with the will to act, effective action is invariably blocked by a complex and opaque political system replete with vested interests in maintaining power and wealth via a weak state and limited services from central government.Breaking the cycleTo break this cycle, Iraq needs a group of professional and able actors outside of government to work with willing elements of the state bureaucracy as a taskforce to pressure for action and accountability. Publishing the recommendations from a hitherto withheld report produced in the aftermath of Basra’s 2018 heath crisis would be a great start.In time, this taskforce could champion the prioritisation of water on the national agenda, the implementation of infrastructure upgrades, and hold more productive conversations with neighbour states.With such a high degree of state fragmentation and dysfunction in Iraq, looking to the central government to provide leadership will not yield results. Engagement with a coalition of non-state actors can begin to address the water crisis and also open a dialogue around new models of governance for other critical issues. This might even be a starting point for rewriting the tattered social contract in Iraq.This piece is based on insights and discussion at a roundtable event, Conflict and the Water Crisis in Iraq, held at Chatham House on March 9 as part of the Iraq Initiative.

ri Egypt and the Gulf: Allies and Rivals By feedproxy.google.com Published On :: Sun, 19 Apr 2020 20:38:18 +0000 20 April 2020 There is and will continue to be an edge of rivalry in Egypt’s relations with the dominant Gulf Arab powers. This paper will focus primarily on the Egypt–Gulf relationship during the Sisi era. Read online Download PDF David Butter Associate Fellow, Middle East and North Africa Programme @DavidCButter 2020-04-20-Egypt-Gulf.jpg Crown Prince of Abu Dhabi Mohammed bin Zayed is welcomed by Egypt’s President Abdel-Fattah el-Sisi in Cairo on 19 June 2017. Photo: Getty Images. Summary Egypt and the Gulf Arab region have long been important poles of political, military economic and cultural power and influence in the Middle East. Under the presidency of Gamal Abdel-Nasser, Egypt was the dominant force in the region, but the balance of power shifted towards the Gulf in the 1970s, as Egypt’s economy faltered and the Gulf Arab states reaped the benefits of resurgent oil prices in the wake of the 1973 OPEC embargo. The popular uprising against President Hosni Mubarak’s regime in 2011 elicited divergent reactions in the Gulf. The leaders of Saudi Arabia and the United Arab Emirates (UAE) were concerned about the risks of a movement for revolutionary change spreading to their own region, while Qatar saw an opportunity to strengthen its regional role through supporting the Muslim Brotherhood.The forcible removal of Egypt’s elected president, Mohammed Morsi of the Muslim Brotherhood, in July 2013 by the army commander, Abdel-Fattah el-Sisi, ushered in a new era in Egypt–Gulf relations. The UAE, Saudi Arabia and Kuwait quickly mobilized financial support for the new administration. Abu Dhabi’s crown prince, Mohammed bin Zayed, known for his intense opposition to the Muslim Brotherhood, signalled his strong support for the new regime by visiting Cairo only weeks after hundreds of Morsi’s supporters were killed.Between July 2013 and August 2016, the UAE, Saudi Arabia and Kuwait provided about $30 billion in aid to the Sisi regime through placing deposits with the Central Bank of Egypt and supplying petroleum products as grants. The UAE sought to link its aid to a programme of economic reforms, but the Egyptian government finally decided in mid-2016 to negotiate a loan agreement with the International Monetary Fund (IMF). Since the signing of the $12 billion loan with the IMF in November 2016, Egypt has no longer been reliant on Gulf Arab financial support, although some of the deposits placed previously have been rolled over on reaching maturity.During the Sisi era, Egypt has benefited from its economic links to the Gulf over a wide spectrum of activities. The UAE and Saudi Arabia in particular are increasingly important export markets for Egyptian companies, as well as major sources of foreign direct investment. The financial aid provided by Sisi’s Gulf allies in 2013–16 has also helped to underpin the surge in Egypt’s arms procurement. Another critical element in the economic relationship is the presence of millions of expatriate Egyptian workers in the Gulf, who are responsible for a large share of the annual inflow of about $25 billion in remittances.Egypt’s most important political relationships in the Gulf have been with Saudi Arabia and the UAE. Ties with Saudi Arabia were affected by the death of King Abdullah at the start of 2015 and by the subsequent emergence of Mohammed bin Salman as the most influential figure in the kingdom. During a visit by King Abdullah’s successor, King Salman, to Cairo in April 2016, Egypt announced a decision to cede sovereignty over two Red Sea islands, Tiran and Sanafir, to Saudi Arabia. Relations soured after this decision was challenged in the Egyptian courts, but the issue was resolved in favour of the deal. Egypt played no active role in the Saudi- and UAE-led intervention in Yemen, but joined its two principal Gulf allies and Bahrain in imposing sanctions on Qatar in mid-2017. Relations between Sisi and Crown Prince Mohammed bin Zayed have remained close throughout the past seven years. The UAE and Egypt have been among the most important external supporters of the Libyan National Army, commanded by Field Marshal Khalifa Haftar, although they have not created an overt alliance in this arena. Egypt has adopted a more prominent diplomatic profile in relation to Libya, while the UAE has been more deeply engaged militarily, to judge from assessments by the panel of experts tasked to monitor adherence to the UN embargo on the supply of weapons to Libya. The relationship between the Egyptian and Emirati leaders is underpinned by a strong shared ideological antipathy to the Muslim Brotherhood.Following the completion of the IMF programme in 2019, the Egyptian economy is in a much stronger position than it was in the early period of Sisi’s rule, even though this has exacted a harsh toll on the 60 per cent of the population classified by the World Bank as poor or vulnerable. There is no pressing need for direct financial support from the Gulf, but Egypt still depends on economic linkages through trade, investment, tourism and remittances. In this respect, the balance of power has tilted marginally back towards Egypt. However, Egypt is still beset by deep internal political contradictions, as reflected in the regime’s heavy reliance on coercion and repression, and the economy remains vulnerable to external shocks – of which the coronavirus pandemic is a prime example.

A recently published Chatham House paper examines the strategic and economic relationship between Egypt and the Gulf, focusing in particular on the period since Abdel-Fattah el-Sisi came to power in Egypt. Author David Butter offers a detailed evaluation of these economic relationships, in the broader context of a strategic alliance that, since 2013, has been informed by a common commitment between Egypt and the UAE in particular to keep in check the Muslim Brotherhood and its regional state supporters, primarily Turkey and Qatar.In this webinar, the author will discuss the paper’s main argument, namely, that the degree of Egypt’s dependence on Gulf countries has fluctuated, and that by 2019, Egypt’s direct financial dependence on the Gulf was significantly reduced by comparison with the initial three years of the Sisi era, although other economic linkages such as investment, trade, remittances and tourism remained strong, with potential for growth. The speaker will also discuss the impact of the global crisis caused by the COVID-19 pandemic on Egypt’s and Gulf countries’ economies and will explore the implications for the relationship between Egypt and the Gulf.This webinar is part of the Chatham House Middle East and North Africa Programme's Online Event Series.

Photo: Getty Images. SummaryFollowing the territorial defeat of Islamic State of Iraq and Syria (ISIS) in northeastern Syria, the Kurdish-led autonomous administration in the region is now grappling with the task of quickly dealing with thousands of the group’s detained members while bringing justice to their victims. To that end, local authorities are focusing on the use of counterterrorism laws and courts to charge captured ISIS members and determine their guilt accordingly.The piecemeal approach to justice is deeply flawed, and raises particular concerns about due process. No precise instruments exist to determine the personal responsibility of ISIS individuals for specific crimes, or for their role in war crimes committed by the group. In any event, the scale of the crimes and the number of victims – as well as severe shortages of resources and workers – make dispensation of justice extremely difficult through the traditional legal system.Not all detained ISIS members receive prison sentences. Individuals who did not hold senior roles in the group’s apparatus and are not accused of ‘major’ crimes (in practice, largely defined as fighting for ISIS and murder) are being released under limited reconciliation deals with tribal leaders. But the involvement of local community leaders in those efforts is not enough to ensure positive results. Many victims are upset at seeing ISIS members walk free without even admitting their guilt publicly or apologizing for the pain they caused.To overcome the limitations of the current, counterterrorism-focused framework, a ‘transitional justice’ approach could provide judicial and non-judicial instruments to establish accountability for ISIS crimes and reduce community resistance to the reintegration of group members. A combination of non-judicial mechanisms such as truth commissions, missing persons’ committees, and reparations and victim-healing programmes could play a vital role in providing ISIS victims with a sense of justice while contributing to peacebuilding and stability.Ignoring the urgency of developing a long-term plan to serve justice and contribute to community healing will almost certainly allow ISIS to continue to prevent the recovery and development of northeastern Syria. This, in turn, risks undermining the stability of the country and the region at large. Department/project Middle East and North Africa Programme Full Article

ri COVID-19 Crisis – Business as Usual for Gaza? By feedproxy.google.com Published On :: Wed, 06 May 2020 14:48:14 +0000 6 May 2020 Mohammed Abdalfatah Asfari Foundation Academy Fellow @mhalabi258 LinkedIn The COVID-19 pandemic has brought unprecedented challenges, economic collapse and strict lockdowns in many parts of the world. For the people of Gaza, this reality is nothing new. 2020-05-06-covid-19-gaza.jpg Palestinians light fireworks above the rubble during the Muslim holy month of Ramadan amid concerns about the spread of the coronavirus disease (COVID-19), in Gaza City , 30 April 2020. Photo by Majdi Fathi/NurPhoto via Getty Images. In August 2012, when the UN released its report Gaza in 2020: A liveable place?, they could not have imagined what the world would look like in 2020: cities under lockdown, restrictions on movement, border closures, widespread unemployment, economic collapse, fear and anxiety and, above all, uncertainty about what the future holds.For Gaza’s population of 2 million people this reality is nothing new. The conditions that the rest of the world are currently experiencing as a result of the COVID-19 pandemic is similar to the tight blockade Gaza has been living under ever since Hamas took over in 2007. Israel has imposed severe restrictions on the movement of people and goods, youth unemployment has reached 60 per cent, and over 80 per cent of Gaza’s population are now dependent on international aid.The people of Gaza are having to face the COVID-19 crisis already at a disadvantage, with poor infrastructure, limited resources and a shortage of the most basic services, such as water and power supply. It also has a fragile health system, with hospitals lacking essential medical supplies and equipment, as well as the capacity to deal with the outbreak as there are only 84 ICU beds and ventilators available. Meanwhile, intra-Palestinian divisions have persisted and were evident in the initial reaction to the pandemic. When President Mahmoud Abbas announced a state of emergency, it took two days for the Hamas-led government in Gaza to follow suit and shut down schools and universities. They later made a separate emergency appeal to address the crisis and prepare for a COVID-19 response in Gaza. This lack of coordination is typical of the way the Palestinian Authority and Hamas approach crisis situations.After the initial uncoordinated response, Hamas, as the de-facto ruler of Gaza, has asserted its ability to control Gaza’s borders by putting in place quarantine measures for everyone who enters the strip, whether through the Erez checkpoint with Israel or the Rafah border with Egypt. They have also assigned 21 hospitals, hotels, and schools as compulsory quarantine centres for all arrivals from abroad, who have to stay in quarantine for 21 days. In comparison, there are 20 quarantine centres in the West Bank. These strict measures have prevented the spread of the virus in the community and confined it to the quarantine centres, with only 20 confirmed cases of COVID-19 as of 6 May. Gaza’s de-facto authorities have also been able to monitor markets and prices to ensure the availability of essential goods.Faced with a major crisis, Al-Qassam Brigades – the armed wing of Hamas – have tried to play the role of a national army by participating in efforts to fight the pandemic. They have relatively good logistical capacity and have contributed to the construction of two quarantine facilities with a total capacity of 1,000 units to prepare for more arrivals into Gaza. At the local level, municipalities have been disinfecting public spaces and facilities in addition to disseminating information about the virus and related preventative and protective measures. Other precautionary measures put in place include closing the weekly open markets, and restricting social gatherings like weddings and funerals.Despite COVID-19, it’s business as usual when it comes to international dealings with Gaza. The key parties in the conflict – Israel, Hamas and the Palestinian Authority – along with the main external actors – Egypt, the United Nations and Qatar – have continued to stick to their policies aimed at keeping the security situation under control and preventing further escalation. Although Israel has allowed entry of pharmaceutical supplies and medical equipment into Gaza during the pandemic, it has kept its restrictions on the movement of goods and people in place, while keeping a close eye on the development of the COVID-19 outbreak in Gaza – a major outbreak here would be a nightmare scenario for Israel.Meanwhile, Qatar has continued to address the humanitarian and economic needs of Gaza in an attempt to ease the pressure and prevent further escalation. It has pledged $150 million over the next six months to help families in Gaza from poorer backgrounds. Gaza has also been discussed by the Middle East Quartet, as Nickolay Mladenov, the UN special coordinator for the Middle East Peace Process, expressed his concern about the risk of a disease outbreak in Gaza during a call with the members of the Quartet.Amid the pandemic, threats are still being exchanged between Israel and Hamas. The Israeli defence minister, Naftali Bennett, requested that in return for providing humanitarian aid to Gaza, Hamas agrees to return the remains of two Israeli soldiers killed in the 2014 war. While openly rejecting Bennett's statement, the leader of Hamas in Gaza, Yahya Sinwar, has offered to move forward with a prisoner swap deal if Israel agrees to release elderly prisoners and detainees in addition to detained women and children. Though dealing with its own COVID-19 outbreak, Egypt has started to mediate between the two parties in an attempt to stabilize the situation and reach a prisoner swap deal.In the wake of this pandemic, lessons should be learned and policies should be examined, by all parties. Firstly, Israel should re-evaluate its security measures towards Gaza by easing restrictions on movement and trade which would have a positive impact on living conditions for Gaza’s population. The current measures have proven to be unsustainable and have contributed to the endless cycle of violence. Secondly, the intra-Palestinian division should end, to save Palestinians from contradictory policies and insufficient capacity on both sides. In fact, all previous attempts have failed to end this self-destructive division and this is due to the absence of political will on both sides. Elections seem to be the only viable path towards unity. Finally, efforts by the international community should go beyond stabilizing the security situation and ongoing crisis inside Gaza, where disruption of normal life is the norm.While the world has reacted to this pandemic with a whole host of new policies and emergency measures, it has remained business as usual when dealing with Gaza. Should COVID-19 spread in Gaza, its people – who have already paid the price of a continuous blockade and intra-Palestinian division for 13 years – will pay a heavy price yet again. However, this time it is not a crisis that they alone will have to face. Full Article
ri Biosynthesis of depsipeptides with a 3-hydroxybenzoate moiety and selective anticancer activities involves a chorismatase [Metabolism] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 Neoantimycins are anticancer compounds of 15-membered ring antimycin-type depsipeptides. They are biosynthesized by a hybrid multimodular protein complex of nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS), typically from the starting precursor 3-formamidosalicylate. Examining fermentation extracts of Streptomyces conglobatus, here we discovered four new neoantimycin analogs, unantimycins B–E, in which 3-formamidosalicylates are replaced by an unusual 3-hydroxybenzoate (3-HBA) moiety. Unantimycins B–E exhibited levels of anticancer activities similar to those of the chemotherapeutic drug cisplatin in human lung cancer, colorectal cancer, and melanoma cells. Notably, they mostly displayed no significant toxicity toward noncancerous cells, unlike the serious toxicities generally reported for antimycin-type natural products. Using site-directed mutagenesis and heterologous expression, we found that unantimycin productions are correlated with the activity of a chorismatase homolog, the nat-hyg5 gene, from a type I PKS gene cluster. Biochemical analysis confirmed that the catalytic activity of Nat-hyg5 generates 3-HBA from chorismate. Finally, we achieved selective production of unantimycins B and C by engineering a chassis host. On the basis of these findings, we propose that unantimycin biosynthesis is directed by the neoantimycin-producing NRPS–PKS complex and initiated with the starter unit of 3-HBA. The elucidation of the biosynthetic unantimycin pathway reported here paves the way to improve the yield of these compounds for evaluation in oncotherapeutic applications. Full Article
ri The transcriptional regulator IscR integrates host-derived nitrosative stress and iron starvation in activation of the vvhBA operon in Vibrio vulnificus [Gene Regulation] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 For successful infection of their hosts, pathogenic bacteria recognize host-derived signals that induce the expression of virulence factors in a spatiotemporal manner. The fulminating food-borne pathogen Vibrio vulnificus produces a cytolysin/hemolysin protein encoded by the vvhBA operon, which is a virulence factor preferentially expressed upon exposure to murine blood and macrophages. The Fe-S cluster containing transcriptional regulator IscR activates the vvhBA operon in response to nitrosative stress and iron starvation, during which the cellular IscR protein level increases. Here, electrophoretic mobility shift and DNase I protection assays revealed that IscR directly binds downstream of the vvhBA promoter PvvhBA, which is unusual for a positive regulator. We found that in addition to IscR, the transcriptional regulator HlyU activates vvhBA transcription by directly binding upstream of PvvhBA, whereas the histone-like nucleoid-structuring protein (H-NS) represses vvhBA by extensively binding to both downstream and upstream regions of its promoter. Of note, the binding sites of IscR and HlyU overlapped with those of H-NS. We further substantiated that IscR and HlyU outcompete H-NS for binding to the PvvhBA regulatory region, resulting in the release of H-NS repression and vvhBA induction. We conclude that concurrent antirepression by IscR and HlyU at regions both downstream and upstream of PvvhBA provides V. vulnificus with the means of integrating host-derived signal(s) such as nitrosative stress and iron starvation for precise regulation of vvhBA transcription, thereby enabling successful host infection.

ri NAD+ biosynthesis in bacteria is controlled by global carbon/nitrogen levels via PII signaling [Microbiology] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 NAD+ is a central metabolite participating in core metabolic redox reactions. The prokaryotic NAD synthetase enzyme NadE catalyzes the last step of NAD+ biosynthesis, converting nicotinic acid adenine dinucleotide (NaAD) to NAD+. Some members of the NadE family use l-glutamine as a nitrogen donor and are named NadEGln. Previous gene neighborhood analysis has indicated that the bacterial nadE gene is frequently clustered with the gene encoding the regulatory signal transduction protein PII, suggesting a functional relationship between these proteins in response to the nutritional status and the carbon/nitrogen ratio of the bacterial cell. Here, using affinity chromatography, bioinformatics analyses, NAD synthetase activity, and biolayer interferometry assays, we show that PII and NadEGln physically interact in vitro, that this complex relieves NadEGln negative feedback inhibition by NAD+. This mechanism is conserved in distantly related bacteria. Of note, the PII protein allosteric effector and cellular nitrogen level indicator 2-oxoglutarate (2-OG) inhibited the formation of the PII-NadEGln complex within a physiological range. These results indicate an interplay between the levels of ATP, ADP, 2-OG, PII-sensed glutamine, and NAD+, representing a metabolic hub that may balance the levels of core nitrogen and carbon metabolites. Our findings support the notion that PII proteins act as a dissociable regulatory subunit of NadEGln, thereby enabling the control of NAD+ biosynthesis according to the nutritional status of the bacterial cell.

ri The hibernating 100S complex is a target of ribosome-recycling factor and elongation factor G in Staphylococcus aureus [Protein Synthesis and Degradation] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 The formation of translationally inactive 70S dimers (called 100S ribosomes) by hibernation-promoting factor is a widespread survival strategy among bacteria. Ribosome dimerization is thought to be reversible, with the dissociation of the 100S complexes enabling ribosome recycling for participation in new rounds of translation. The precise pathway of 100S ribosome recycling has been unclear. We previously found that the heat-shock GTPase HflX in the human pathogen Staphylococcus aureus is a minor disassembly factor. Cells lacking hflX do not accumulate 100S ribosomes unless they are subjected to heat exposure, suggesting the existence of an alternative pathway during nonstressed conditions. Here, we provide biochemical and genetic evidence that two essential translation factors, ribosome-recycling factor (RRF) and GTPase elongation factor G (EF-G), synergistically split 100S ribosomes in a GTP-dependent but tRNA translocation-independent manner. We found that although HflX and the RRF/EF-G pair are functionally interchangeable, HflX is expressed at low levels and is dispensable under normal growth conditions. The bacterial RRF/EF-G pair was previously known to target only the post-termination 70S complexes; our results reveal a new role in the reversal of ribosome hibernation that is intimately linked to bacterial pathogenesis, persister formation, stress responses, and ribosome integrity.

ri Modification of a PE/PPE substrate pair reroutes an Esx substrate pair from the mycobacterial ESX-1 type VII secretion system to the ESX-5 system [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 Bacterial type VII secretion systems secrete a wide range of extracellular proteins that play important roles in bacterial viability and in interactions of pathogenic mycobacteria with their hosts. Mycobacterial type VII secretion systems consist of five subtypes, ESX-1–5, and have four substrate classes, namely, Esx, PE, PPE, and Esp proteins. At least some of these substrates are secreted as heterodimers. Each ESX system mediates the secretion of a specific set of Esx, PE, and PPE proteins, raising the question of how these substrates are recognized in a system-specific fashion. For the PE/PPE heterodimers, it has been shown that they interact with their cognate EspG chaperone and that this chaperone determines the designated secretion pathway. However, both structural and pulldown analyses have suggested that EspG cannot interact with the Esx proteins. Therefore, the determining factor for system specificity of the Esx proteins remains unknown. Here, we investigated the secretion specificity of the ESX-1 substrate pair EsxB_1/EsxA_1 in Mycobacterium marinum. Although this substrate pair was hardly secreted when homologously expressed, it was secreted when co-expressed together with the PE35/PPE68_1 pair, indicating that this pair could stimulate secretion of the EsxB_1/EsxA_1 pair. Surprisingly, co-expression of EsxB_1/EsxA_1 with a modified PE35/PPE68_1 version that carried the EspG5 chaperone-binding domain, previously shown to redirect this substrate pair to the ESX-5 system, also resulted in redirection and co-secretion of the Esx pair via ESX-5. Our results suggest a secretion model in which PE35/PPE68_1 determines the system-specific secretion of EsxB_1/EsxA_1. Full Article
ri 5-Ethynyl-2'-deoxycytidine and 5-ethynyl-2'-deoxyuridine are differentially incorporated in cells infected with HSV-1, HCMV, and KSHV viruses [Microbiology] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 Nucleoside analogues are a valuable experimental tool. Incorporation of these molecules into newly synthesized DNA (i.e. pulse-labeling) is used to monitor cell proliferation or to isolate nascent DNA. Some of the most common nucleoside analogues used for pulse-labeling of DNA in cells are the deoxypyrimidine analogues 5-ethynyl-2'-deoxyuridine (EdU) and 5-ethynyl-2'-deoxycytidine (EdC). Click chemistry enables conjugation of an azide molecule tagged with a fluorescent dye or biotin to the alkyne of the analog, which can then be used to detect incorporation of EdU and EdC into DNA. The use of EdC is often recommended because of the potential cytotoxicity associated with EdU during longer incubations. Here, by comparing the relative incorporation efficiencies of EdU and EdC during short 30-min pulses, we demonstrate significantly lower incorporation of EdC than of EdU in noninfected human fibroblast cells or in cells infected with either human cytomegalovirus or Kaposi's sarcoma-associated herpesvirus. Interestingly, cells infected with herpes simplex virus type-1 (HSV-1) incorporated EdC and EdU at similar levels during short pulses. Of note, exogenous expression of HSV-1 thymidine kinase increased the incorporation efficiency of EdC. These results highlight the limitations when using substituted pyrimidine analogues in pulse-labeling and suggest that EdU is the preferable nucleoside analogue for short pulse-labeling experiments, resulting in increased recovery and sensitivity for downstream applications. This is an important discovery that may help to better characterize the biochemical properties of different nucleoside analogues with a given kinase, ultimately leading to significant differences in labeling efficiency of nascent DNA.

ri The streptococcal multidomain fibrillar adhesin CshA has an elongated polymeric architecture [Microbiology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The cell surfaces of many bacteria carry filamentous polypeptides termed adhesins that enable binding to both biotic and abiotic surfaces. Surface adherence is facilitated by the exquisite selectivity of the adhesins for their cognate ligands or receptors and is a key step in niche or host colonization and pathogenicity. Streptococcus gordonii is a primary colonizer of the human oral cavity and an opportunistic pathogen, as well as a leading cause of infective endocarditis in humans. The fibrillar adhesin CshA is an important determinant of S. gordonii adherence, forming peritrichous fibrils on its surface that bind host cells and other microorganisms. CshA possesses a distinctive multidomain architecture comprising an N-terminal target-binding region fused to 17 repeat domains (RDs) that are each ∼100 amino acids long. Here, using structural and biophysical methods, we demonstrate that the intact CshA repeat region (CshA_RD1–17, domains 1–17) forms an extended polymeric monomer in solution. We recombinantly produced a subset of CshA RDs and found that they differ in stability and unfolding behavior. The NMR structure of CshA_RD13 revealed a hitherto unreported all β-fold, flanked by disordered interdomain linkers. These findings, in tandem with complementary hydrodynamic studies of CshA_RD1–17, indicate that this polypeptide possesses a highly unusual dynamic transitory structure characterized by alternating regions of order and disorder. This architecture provides flexibility for the adhesive tip of the CshA fibril to maintain bacterial attachment that withstands shear forces within the human host. It may also help mitigate deleterious folding events between neighboring RDs that share significant structural identity without compromising mechanical stability. Full Article
ri Pro-515 of the dynamin-like GTPase MxB contributes to HIV-1 inhibition by regulating MxB oligomerization and binding to HIV-1 capsid [Microbiology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Interferon-regulated myxovirus resistance protein B (MxB) is an interferon-induced GTPase belonging to the dynamin superfamily. It inhibits infection with a wide range of different viruses, including HIV-1, by impairing viral DNA entry into the nucleus. Unlike the related antiviral GTPase MxA, MxB possesses an N-terminal region that contains a nuclear localization signal and is crucial for inhibiting HIV-1. Because MxB previously has been shown to reside in both the nuclear envelope and the cytoplasm, here we used bioinformatics and biochemical approaches to identify a nuclear export signal (NES) responsible for MxB's cytoplasmic location. Using the online computational tool LocNES (Locating Nuclear Export Signals or NESs), we identified five putative NES candidates in MxB and investigated whether their deletion caused nuclear localization of MxB. Our results revealed that none of the five deletion variants relocates to the nucleus, suggesting that these five predicted NES sequences do not confer NES activity. Interestingly, deletion of one sequence, encompassing amino acids 505–527, abrogated the anti-HIV-1 activity of MxB. Further mutation experiments disclosed that amino acids 515–519, and Pro-515 in particular, regulate MxB oligomerization and its binding to HIV-1 capsid, thereby playing an important role in MxB-mediated restriction of HIV-1 infection. In summary, our results indicate that none of the five predicted NES sequences in MxB appears to be required for its nuclear export. Our findings also reveal several residues in MxB, including Pro-515, critical for its oligomerization and anti-HIV-1 function. Full Article

CHP15MSF.jpg Médecins Sans Frontières (MSF) has been awarded the Chatham House Prize 2015.The Chatham House Prize is presented annually to the person or organization deemed by members of the Royal Institute of International Affairs to have made the most significant contribution to the improvement of international relations in the previous year.This year, members voted for MSF in recognition of its work in combating the 2014 Ebola outbreak in West Africa. MSF was among the first groups to respond to the epidemic in March of that year and remained engaged on the ground throughout the crisis, caring for the majority of patients in Liberia, Guinea and Sierra Leone. MSF leaders and staff were persistent and forceful in their action to halt the spread of the epidemic and, as a result, were instrumental in saving thousands of lives. Dr Joanne Liu, MSF’s international president, will represent MSF at the Chatham House Prize award ceremony in London where she will be presented with a crystal award and a scroll, signed by Her Majesty The Queen, patron of the institute. Previous recipients of the Prize include former president Lula of Brazil, Burmese democracy campaigner Aung San Suu Kyi, former US secretary of state Hillary Clinton, and Melinda Gates, co-founder of the Bill and Melinda Gates Foundation.Dr Robin Niblett CMG, director of Chatham House, said: 'I warmly congratulate Médecins Sans Frontières on being voted the recipient of this year's Chatham House Prize. This is the first time an organization has been awarded the Prize and I am delighted that their vital work has been recognized in this way. MSF led the fight against Ebola by sounding an early alarm on its dangers. It put into place a highly effective operation that saved thousands of lives, and helped prevent a more wide-spread catastrophe, risking and, in some cases, losing the lives of its own staff.'Dr Joanne Liu, international president of MSF said:'I am honoured that MSF will be the recipient of this year’s Chatham House Prize and I look forward to accepting this award on behalf of the thousands of people who worked in the Ebola outbreak. This includes the doctors, nurses and logisticians who volunteered from around the world, and the thousands more national staff in Guinea, Liberia, Mali, Nigeria and Sierra Leone who made our work possible. Knowing that they did this while coping with the fear of Ebola in their communities and in the face of incredible stigma makes their contribution even more remarkable. While we continue to work on the ground, our focus is also trying to ensure that next time there is an outbreak, that patients get the care and treatment they need, on time, before it spreads and turns into a killer epidemic. But we all still have a long way to go and it is important that we work together to respond to these challenges and opportunities.'Members EventChatham House Prize 2015: In Conversation with Dr Joanne Liu of Médecins Sans Frontières13 October 2015 - 17:00 - 18:00SponsorsChatham House gratefully acknowledges the support of our lead sponsor Royal Dutch Shell, and other sponsors AIG, BHP Billiton, Chevron and DTCC.NomineesThere were three other nominees for the Chatham House Prize 2015:Mahamadou Issoufou, President, Republic of Niger (2011-) Juan Manuel Santos, President, Republic of Colombia (2010-)Angela Merkel, Chancellor, Federal Republic of Germany (2005-)About the Chatham House PrizeThe annual Chatham House Prize, launched in 2005, is awarded to the person or organization that is deemed by Chatham House members to have made the most significant contribution to the improvement of international relations in the previous year.The selection process draws on the expertise of Chatham House's research teams and three presidents, who nominate candidates.

ri Syria's Economy: Picking up the Pieces By feedproxy.google.com Published On :: Fri, 10 Jul 2015 09:33:00 +0000 23 June 2015 20150623SyriaEconomy.jpg Photo: Getty Images/Stringer. On Tuesday 23 June, Chatham House will publish Syria's Economy: Picking up the Pieces, a comprehensive account of the state of the Syrian economy and its prospects. The paper, by David Butter, associate fellow on the Middle East and North Africa Programme, finds that:Syria's economy has contracted by more than 50 per cent in real terms since 2011, with the biggest losses in output coming in the energy and manufacturing sectors. Agriculture has assumed a bigger role in national output in relative terms, but food production has fallen sharply as a result of the conflict.Inflation has averaged 51 per cent between January 2012 and March 2015, according to the monthly data issued by the government, and the Syrian pound has depreciated by about 80 per cent since the start of the conflict.In the first half of 2015, the regime has shown increasing signs of strain on both the military and the economic fronts. The regime has lost ground to rebel forces, and the Syrian pound has depreciated at the fastest rate since the conflict began.Continued support from Iran, in the form of oil supplies and import credits, will come with political and economic conditions.The question arises as to whether a dramatic worsening in the economic situation might be the catalyst for the regime’s military collapse or for an externally imposed political settlement against Assad’s wishes; or whether further military setbacks might be the trigger for the government’s economic collapse.

ri Asia-Pacific security is about more than just China and the US By feedproxy.google.com Published On :: Fri, 09 Oct 2015 14:22:43 +0000 21 September 2015 20150924AsiaPacific.jpg Photo: Jacob Parakilas/Chatham House. Seeing geo-strategic rivalry between the US and China as the sole variable in Asia-Pacific security risks becoming a self-fulfilling prophecy, according to a forthcoming Chatham House paper. As Xi Jinping’s visit to the US approaches, The Asia-Pacific Power Balance: Beyond the US–China Narrative, warns against deploying Cold War-type narratives that pit the two countries against each other. Such narratives not only misunderstand the complexity of the region and the growing influence of India, Japan and Indonesia, but also risk increasing the likelihood of conflict and of missing vital opportunities for future cooperation. The paper, by John Nilsson-Wright, Tim Summers and Xenia Wickett argues that by focusing too heavily on the US and China, policymakers risk narrowing the aperture through which they evaluate policy choices regarding major regional challenges. Some of the key findings include the following:MilitaryDespite rapidly rising defence spending across Asia, the relative importance of traditional military means is declining relative to instruments such as development assistance and cyber offence.The militaries of Japan and India are becoming – in very different ways – more versatile and potentially expanding their remits. In the future, there will be a larger number of more capable military powers in the region, including South Korea and Vietnam.Current perceptions that the main dynamic is China’s rising military capabilities outstripping others in the region, therefore, need to be tempered. India’s defence spending, for example, as a percentage of GDP has surpassed China’s for the past several decades.EconomicsAlthough China has the world’s second-largest economy and – despite recent problems – is growing faster than most major economies, its growth rate is in secular decline. China has gone from near-constant double-digit growth over the past four decades to 7.4 per cent in 2014 and could dip below 7 per cent this year.Whilst India’s economy remains notably smaller than those of China, the US and Japan, it will surpass China’s growth rate this year and has a lot of potential.If the Trans-Pacific Partnership (TPP) is successfully negotiated, the potential for integration and growth between the United States, Japan and the other 10 TPP members may reduce their current trade dependence on China.DemographyThe demography of Asia is another reason to look beyond the US-China nexus, as China faces the challenge of an aging society, while countries such as India have the advantage of a younger population and decades of demographic dividend ahead of them.Likewise populations across much of Southeast Asia, such as the Philippines and Indonesia are growing rapidly and expanding their middle classes.

ri Risk of serious cyber attacks on nuclear facilities underestimated, says new report By feedproxy.google.com Published On :: Fri, 09 Oct 2015 15:22:30 +0000 2 October 2015 20150930CyberSecurity.jpg Workers at the Wolsong nuclear power plant participate in an anti-cyber attack exercise, Gyeongju, South Korea. Photo: Getty Images. The risk of a serious cyber attack on civil nuclear infrastructure is growing, as facilities become ever more reliant on digital systems and make increasing use of commercial ‘off-the-shelf’ software, according to a major new report from Chatham House.Cyber Security at Civil Nuclear Facilities: Understanding the Risks is the result of an 18-month study that draws on in-depth interviews with 30 leading industry practitioners based in more than eight countries. It found that the trend to digitization, when combined with a lack of executive-level awareness of the risks involved, means that nuclear plant personnel may not realize the full extent of their cyber vulnerability and are thus inadequately prepared to deal with potential attacks. Specific findings include: The conventional belief that all nuclear facilities are ‘air gapped’ (isolated from the public internet) is a myth. The commercial benefits of internet connectivity mean that a number of nuclear facilities now have VPN connections installed, which facility operators are sometimes unaware of.Search engines can readily identify critical infrastructure components with such connections.Even where facilities are air gapped, this safeguard can be breached with nothing more than a flash drive.Supply chain vulnerabilities mean that equipment used at a nuclear facility risks compromise at any stage.A lack of training, combined with communication breakdowns between engineers and security personnel, means that nuclear plant personnel often lack an understanding of key cyber security procedures.Reactive rather than proactive approaches to cyber security contribute to the possibility that a nuclear facility might not know of a cyber attack until it is already substantially under way.In the light of these risks, the report outlines a blend of policy and technical measures that will be required to counter the threats and meet the challenges. Recommendations include:Developing guidelines to measure cyber security risk in the nuclear industry, including an integrated risk assessment that takes both security and safety measures into account.Engaging in robust dialogue with engineers and contractors to raise awareness of the cyber security risk, including the dangers of setting up unauthorized internet connections.Implementing rules, where not already in place, to promote good IT hygiene in nuclear facilities (for example to forbid the use of personal devices) and enforcing rules where they do exist.Improving disclosure by encouraging anonymous information sharing and the establishment of industrial CERTs (Computer Emergency Response Team).Encouraging universal adoption of regulatory standards.

ri Radical new business model for pharmaceutical industry needed to avert antibiotic resistance crisis By feedproxy.google.com Published On :: Mon, 12 Oct 2015 09:19:24 +0000 7 October 2015 20151009Antibiotics.jpg High-level complex of physiologically active antibiotic substance extracted from blastema at the Arctic Innovation Center (AIC) of Ammosov, North-Eastern Federal University (NEFU) in Yakutsk. Photo: Yuri Smityuk/ITAR-TASS Photo/Corbis. Revenues for pharmaceutical companies need to be 'delinked' from sales of antibiotics to avoid their over-use and avert a public health crisis, says a new report from the think-tank Chatham House.Over-use of antibiotics is contributing to the growing resistance of potentially deadly bacteria to existing drugs, threatening a public health crisis in the near future. The report notes that, by 2050, failing to tackle antibiotic resistance could result in 10 million premature deaths per year. Novel antibiotics to combat resistant pathogens are thus desperately needed, but market incentives are exacerbating the problem. Towards a New Global Business Model for Antibiotics: Delinking Revenues from Sales states that, 'The current business model requires high levels of antibiotic use in order to recover the costs of R&D. But mitigating the spread of resistance demands just the opposite: restrictions on the use of antibiotics.' To tackle this catch-22 problem, the Centre on Global Health Security at Chatham House recommends the establishment of a global body to implement a radical new business model for the industry, which would encourage investment and promote global access to - and conservation of - antibiotics. The current business model has several perverse effects. As R&D is an inherently risky and costly endeavour, the industry is chronically under-investing in new treatments. Today, few large pharmaceutical companies retain active antibacterial drug discovery programmes. Re-stoking the industry's interest in antibiotics would be one of the primary roles of the new body. Secondly, the need to recover sunk cost under the current business model encourages both high prices and over-marketing of successful drugs, making potentially life-saving treatments unaffordable to many in developing countries, while simultaneously encouraging over-use in developed markets and increasing resistance. The new global body would address these challenges by ‘delinking’ pharmaceutical revenues from sales of antibiotics. It would do this by directly financing the research and development of new drugs, which it would then acquire at a price based on production costs rather than the recovery of R&D expenses. Acquisition could take the form of procurement contracts with companies, the purchase of full IP rights or other licensing mechanisms. This would enable it to promote global access to antibiotics while simultaneously restricting over-use. Conservation would be promoted through education, regulation and good clinical practice, with the report recommending that 'proven conservation methods such as antibiotic stewardship programmes… be incentivized and implemented immediately.'Priorities for R&D financing would be based on a comprehensive assessment of threats arising from resistance. Antibiotics would qualify for the highest level of financial incentives if they combat resistant pathogens posing a serious threat to human health. Finance for the new body would come from individual nation states, with the report noting that this could 'begin with a core group of countries with significant research activity and large antibiotic markets, (though) it is envisaged that all high income countries should make an appropriate financial contribution.' It is not yet clear exactly how much funding would be necessary to combat resistance, but with inaction expected to cost $100 trillion in cumulative economic damage, the report argues that 'an additional global investment of up to $3.5 billion a year (about 10 per cent of the current value of global sales of antibiotics) would be a bargain.'

ri Britain should treat Europe as its ‘inner circle’ or risk losing international influence By feedproxy.google.com Published On :: Mon, 19 Oct 2015 09:05:23 +0000 13 October 2015 20151019BritanEuropeWorld.jpg British Prime Minister David Cameron sits with other world leaders at the G20 summit in Brisbane, Australia on 15 November 2014. Photo by Getty Images. Given the international context, it is in Britain’s best interests to treat Europe as the ‘inner circle’ of its foreign, security and international economic policy, argues Dr Robin Niblett, director of Chatham House, in a new paper.The British government’s approach since 2010 of seeking to enhance the UK's relations with the world’s emerging powers while balancing these with relationships with the United States and Europe has had only limited success. With constrained resources, and in the face of intense global economic competition, mounting security challenges and decaying international institutions, trying to commit the UK equally on all three fronts will not succeed in the future.Britain, Europe and the World: Rethinking the UK’s Circles of Influence calls for a different mindset and strategy towards the UK’s place in the world – one in which Britain is surrounded by three concentric circles of influence:The first or ‘inner circle’ is the EU, the region with which the UK’s relationships need to be strongest and most active.The ‘second circle’ consists of the protective and enabling set of economic and security relationships with the US.Finally, an ‘outer circle’ comprises the UK’s other key bilateral and institutional relationships.Should the UK vote to remain in the EU, policy-makers should commit to placing the EU at the centre of Britain's foreign policy, using the country’s economic weight, diplomatic skills and networks to play a leading role in leveraging more effective EU-wide policies. Should the country vote to leave, the UK and the EU would enter an extended period of dislocation before arriving at a new, mutually diminished settlement. British policy-makers would be forced to deal and negotiate with the EU on critical policy issues from the outside. It is hard to see, argues Dr Niblett, how that could lead to EU policies or an international context more in line with British interests. Despite its structural flaws and competing national interests, the EU offers the best prospects for managing the rapidly changing global context, for three main reasons:First, it allows the UK to leverage the EU’s global economic weight to enhance the UK’s economic interests internationally, including securing beneficial trade agreements and contributing to EU and global standard-setting and rule-writing. Conversely, leaving would require the UK to renegotiate over 100 trade agreements, and would disadvantage UK interests in EU markets, including making EU governments less likely to liberalize services. Second, it gives the UK a say in designing new EU initiatives to strengthen both British and European security in the face of diverse threats, whether managing the flow of refugees and other emigrants; combatting terrorism; or managing a more assertive Russia and the fallout from a disintegrating Middle East. Third, cooperating with other EU members offers a way of maximizing opportunities to find joint solutions to shared problems, whether in terms of responding to climate change; managing growing cyber insecurity; reversing the decay of governance in failing states; or combating the rise of dangerous non-state actors.Dr Robin Niblett said:‘Britain is likely to be richer, safer and more influential in the coming decades if it treats Europe as the ‘inner circle’ of its foreign policy. For a mid-sized country like the UK, being a major player in a strong regional institution can offer a critical lever for international influence. In the UK’s case, this means choosing to be a leading player in the world’s principal civilian power, the European Union.’ Editor's notes Read Britain, Europe and the World: Rethinking the UK's Circles of InfluenceChatham House will host a press briefing with Dr Robin Niblett on Monday 19 October at 11:00-11:45 BST.

ri First ever global analysis of refugees’ energy use: High costs and poor supply undermine humanitarian assistance By feedproxy.google.com Published On :: Tue, 17 Nov 2015 11:50:49 +0000 11 November 2015 20151119MovingEnergyInitiative.jpg A migrant girl looks at a light illuminating a camp site of refugees and migrants on the Greek island of Lesbos, 4 October 2015. Photo: Getty Images. About 90 per cent of refugees living in camps have no access to electricity and many lack any form of lighting at night, says a Chatham House report for the Moving Energy Initiative. Energy poverty in refugee settlements is not on the radar of international initiatives and humanitarian agencies are ill-equipped to deal with the scale of need. Heat Light and Power for Refugees: Saving Lives, Reducing Costs zooms in on the energy needs of refugees and displaced people worldwide, and presents the first ever estimates of the volume and costs of what they use.'The problem goes beyond electricity. 80 per cent of those in camps rely on firewood for cooking and, as a result, we estimate that some 20,000 people die prematurely each year due to the pollution from indoor fires. Exposure to extremes of cold and heat are also killers for people living in flimsy, temporary shelter,' says Glada Lahn, senior research fellow at Chatham House. 'The current lack of provision for energy undermines the fundamental aims of humanitarian assistance,' she adds.There are nearly 60 million forcibly displaced people in the world, and they pay staggering costs for energy. The 83,277 households living in Dadaab in Kenya, the world’s largest refugee settlement, spent an estimated $6.2 million on firewood last year, which accounts for approximately 24 per cent of their overall household income. (The average UK household spent 4 per cent of its income on energy in 2011.) In Uganda, almost half of refugee households surveyed by the UNHCR skip meals because they do not have enough fuel to cook with.'The imperative is to find humane, creative and cost-effective ways to respond to the needs of so many individuals, most of whom are women and children. Improving access to clean, safe and sustainable energy offers a promising way forward,' says Kofi Annan in the report’s foreword.The report calls for an overhaul in the way that heat, light and power are delivered in humanitarian crises. It makes the case for new partnerships between humanitarian agencies and private providers to increase clean energy access in refugee settlements. Investment in energy infrastructure will also benefit host communities in some of the world’s poorest countries.'As refugee households spend approximately $2.1 billion on energy each year, developing local markets for energy services could be part of a mix of solutions,' adds Lahn. 'Using green, culturally appropriate technologies could save lives, reduce CO2 emissions by 11 million tonnes per year and radically improve living standards. Introducing even the most basic solutions, such as improved cookstoves and basic solar lanterns, could save $323 million a year in fuel costs.' Other findings include:Rape and violence against women is common in many unlit camps. Only 4 per cent of women and girls in households in the Goudoubo camp in Burkina Faso would go out after dark due to the lack of streetlights.Wood equalling around 49,000 football pitches worth of forest (64,700 acres) is burned by displaced families living in camps each year, mainly in countries suffering severe deforestation, because they have no alternative sources of energy.Firewood consumption emits nearly twice as much CO2 as liquid petroleum gas and produces little energy in comparison to its carbon intensity.International Development Minister Grant Shapps said:‘Across sub-Saharan Africa, hundreds of millions of people still do not have access to electricity. Women and girls are at risk of violence after dark, families are forced to inhale toxic kerosene fumes, and energy remains unaffordable for many.‘With the technology in place and investors coming on board, the time to act is now. The UK's Energy Africa campaign is already kick-starting a solar revolution across the continent.‘Supporting the Moving Energy Initiative is another way Britain can help boost access to clean, reliable and affordable energy. This will transform people’s lives and help achieve the UN’s goal of universal energy access by 2030.’ Editor's notes Read Heat Light and Power for Refugees: Saving Lives, Reducing Costs by Glada Lahn and Owen Grafham.To link back to the report in an article, please use this landing page for the final report.The Moving Energy Initiative (MEI) is a collaboration between GVEP International, Chatham House, Practical Action Consulting, the Norwegian Refugee Council (NRC) and the United Nations High Commissioner for Refugees (UNHCR).

ri Reducing meat consumption critical to achieving global climate goal By feedproxy.google.com Published On :: Tue, 24 Nov 2015 16:35:54 +0000 18 November 2015 20151124DietClimateChange.jpg Grand Central Market in Los Angeles, California, October 2015. Photo: Getty Images. In the week before governments assemble in Paris to agree a global climate deal, a new report from Chatham House shows that a worldwide shift to healthier diets could help close the gap between current emissions reduction plans and what is needed to prevent dangerous climate change.Pledges from countries attending the 21st UNFCCC Conference of the Parties put the world on track for around 3 degrees of warming by 2100, leaving governments with much more still to do. Changing diets to healthy levels of meat consumption could generate a quarter of the remaining emission reductions needed to keep warming below the ‘danger level’ of 2 degrees Celsius – the main goal of the climate negotiations.Changing Climate, Changing Diets: Pathways to Lower Meat Consumption by Laura Wellesley, Catherine Happer and Antony Froggatt argues that, ultimately, dietary change is fundamental to achieving the 2 degrees goal. The livestock sector is already responsible for 15 per cent of global greenhouse gas emissions. Unless strong demand growth for meat is curtailed, livestock sector emissions will increase to the point where dangerous climate change is unavoidable.Dietary change would also have major health benefits. Global per capita meat consumption is already above healthy levels, and double the recommended amount in industrialized countries. Too much red and processed meat is associated with an increased risk of non-communicable diseases, in particular cancer, as found most recently by the World Health Organization.'Reducing meat consumption is a real win-win for health and for the climate,' says report author Laura Wellesley. 'As governments look for strategies to close the Paris emissions gap quickly and cheaply, dietary change should be high on the list.'However, the report finds that governments are ignoring the opportunity. Reducing meat consumption does not feature in a single national emissions reduction plan submitted in advance of the Paris meeting. Governments are afraid to interfere in lifestyle choices for fear of public backlash.But new research undertaken for the report, including an innovative public survey in 12 countries and focus groups in Brazil, China, the United Kingdom, and the United States shows that government fears are exaggerated. Once aware of the link between meat and climate change, consumers accept the need for government action. Even unpopular interventions to make meat more expensive, for example through a carbon tax, would face diminishing resistance as publics come to understand the rationale behind intervention.To build support for government action, the report recommends initiatives to raise public awareness of the climate and health impacts of excessive meat consumption. Governments should pursue comprehensive strategies to shift diets, including policies on labelling, public procurement, regulation and pricing.'Raising awareness about the health and environmental impacts of meat is an important first step, but on its own it will not lead to significant behaviour change. Governments must do more to influence diets,' added Wellesley. Editor's notes Read Changing Climate, Changing Diets: Pathways to Lower Meat Consumption by Laura Wellesley, Catherine Happer and Antony Froggatt.This report is embargoed until 00:01 GMT on Tuesday 24 November. To arrange an interview with the authors please contact the press office.This research project was carried out in conjunction with Glasgow University Media Group. Further research findings:Meat consumption has already reached excessive levels in many Western countries: in industrialized countries, it is around twice the amount deemed healthy by experts. And with the rise of new meat-eating middle classes in developing countries, global meat consumption is set to increase by 76 per cent by 2050.Action on diets could also lower the costs of climate action across the rest of the economy by 50 per cent, while presenting a win-win strategy for policy-makers in terms of public health benefits.In the UK and US, men are more likely to want to eat more meat than women.In China, the desire to eat meat increases in line with income, while in the US and UK, wealthier people are less likely to say they want to eat more meat.In the UK and US, climate change is a more politicized and divisive issue, and people are more sceptical about the science.The US respondents remained most sceptical about the data presented to them.In the UK and US, people were reluctant to take personal responsibility for climate change, seeing it as something those in public roles were responsible for.The highest levels of concern around food safety and animal welfare associated with meat production were found among US respondents. People in the UK were most likely to eat less meat for health reasons.In the UK and US, meat was associated positively with nutrition and fulfilment, but negatively with health and food safety.The executive summary of the report is available in Mandarin and Portuguese.

ri By enabling formal trade, Nigeria can unleash its vast potential By feedproxy.google.com Published On :: Mon, 07 Dec 2015 16:18:19 +0000 3 December 2015 20151207Nigeriabooming.jpg Nigeria’s booming informal trade is costly for society, business and government, yet a critical opportunity exists to formalize such trade and drive more sustainable and less volatile growth, argues a new report from Chatham House.According to one estimate, informal activity accounts for up to 64 per cent of Nigeria’s GDP. Nigeria's Booming Borders: The Drivers and Consequences of Unrecorded Trade finds that this is a result of obstacles that impede trading through formal channels. These drivers include bureaucratic burdens and other factors, such as:The need for Nigerian businesses to produce at least nine documents in order to send an export shipment and at least 13 in order to bring in an import consignment.Rigid and dysfunctional foreign-exchange regulations that push most smaller traders into the incompletely regulated parallel exchange market.Corruption and unofficial ‘taxation’, especially on major border highways, which delegitimize formal channels and encourage the use of smuggling routes.As a result, the state loses direct tax revenues that would be generated by formal cross-border trade. This is not just siphoned into the informal economy; some is lost entirely. For example, many shippers opt to dock in neighbouring countries rather than deal with the expense and difficulty of using Nigeria’s ports.Informal trade also undermines the social contract between the private sector and government. The state lacks tax revenues to pay its officials, improve infrastructure or implement reforms, while traders feel the government provides no services in return for any taxes they might pay.‘Every day tens of thousands of unofficial payments are made, none destined for the government. Policy-makers need to create an environment that encourages trade to flow through formal channels and capture lost revenue’, says co-author Leena Koni Hoffmann.‘Formalization would assist Nigeria to pursue more high-quality, high-tech economic activity at a time when rising labour costs in Asia are creating scope for Nigerian manufacturers to compete’, she adds.The report makes a number of recommendations for how Nigeria could encourage more formal trade, including:Strengthening the resources and capacity of the Federal Ministry of Industry, Trade and Investment to coordinate action across key government ministries, departments and agencies, as well as public and private stakeholders.Prioritizing engagement in the development of Economic Community of West African States (ECOWAS) trade policies and fully implementing the ECOWAS Protocol on Free Movement of Persons to reduce harassment at borders.Allowing banks to operate simple services for small and medium-sized businesses to make trade payments directly from Nigerian naira to CFA francs and vice versa.Improving basic facilities that support traders, including improving the efficiency of border posts, installing truck parks and all-weather surfacing on market access roads, and introducing online booking for trucks to enter ports.Separating responsibilities for assessing duty and tariff liabilities from revenue collection in order to reduce opportunities for corruption, an approach already tested with success by the Lagos State Internal Revenue Service.Increasing funding and technical support for the National Bureau of Statistics, which has a significant role to play in measuring and capturing more of Nigeria’s external trade.Interviews conducted for the report reveal that business people would welcome the opportunity to pay taxes, but only if they received assurance that these payments would represent a contract with government guaranteeing that conditions for business would be improved.‘As Africa’s largest economy, formalizing external trade would allow Nigeria to fulfil its potential as the trading engine of the West and Central African economy and shape the business landscape across the region,’ says co-author Paul Melly.

ri Centre on Global Health Security collaborates with the Gates Foundation at the Munich Security Conference By feedproxy.google.com Published On :: Mon, 22 Feb 2016 11:03:22 +0000 22 February 2016 Support from the Bill & Melinda Gates Foundation has enabled Chatham House to develop a global health security track at the Munich Security Conference (MSC). 2016-02-22-MSC-Niblett.jpg The primary objectives of this three-year partnership are to integrate consideration of global health security challenges into the MSC agenda, highlight the threats from infectious diseases and stimulate discussion of the importance of investment in global health, particularly in low- and middle-income countries. At the 2016 MSC, the Chatham House Centre on Global Health Security facilitated a roundtable on civilian access to health care during conflict and a panel session entitled 'The Plot Sickens – The Health-Security Nexus'. This marked the first time health security had been featured in the main conference, and highlights the growing significance of health security to broader global stability and security. Chatham House produced, with support from the Gates Foundation, a short film including insights from UN Secretary-General Ban Ki-moon and Melinda Gates to introduce themes that were discussed as key security threats on the health-security nexus.Initiated in 2015, the collaboration will continue with a Chatham House roundtable and a plenary session at the MSC’s Core Group Meeting in Addis Ababa in April, and further contributions to the 2017 MSC agenda.

ri The refugee crisis: A European call for action By feedproxy.google.com Published On :: Fri, 18 Mar 2016 10:02:48 +0000 18 March 2016 Open Letter by the conveners of the Vision Europe Summit regarding the refugee crisis in Europe and the necessity to act now. European leaders need to implement common European solutions to the refugee crisis. Only joint solutions can credibly and effectively reduce the growing human suffering and social and political turmoil.The refugee crisis poses a serious challenge, both to the welfare of refugees and to European societies. In 2015, more than 1.5 million migrants crossed into the European Union. From Italy to Poland, and from Greece to Germany, countries face immense challenges in responding to requests for humanitarian aid, asylum, and integration. The associated integration challenges in housing, language, work and welfare are already formidable. Failing to manage them properly poses serious threats to social cohesion and political stability.European countries have had sufficient time to analyse and assess the long-standing challenges which created the current crisis. Now it is time to act – not individually and at the expense of others, but jointly and in a spirit of European solidarity. This is why Vision Europe – a partnership between seven leading think tanks and foundations in Europe – will in 2016 focus its efforts on providing practical solutions to the current refugee crisis, and its root causes. We, the seven signatories, writing in an individual capacity, see an urgent need for a common European approach, to compliment local and national efforts.At present, there is no consensus among member states on how to respond to the crisis, neither on the objectives to be achieved or the methods to be used. But disagreements on substance must be overcome now. Building on current discussions, we propose a comprehensive agenda at the EU level, with five major dimensions.First, it is important to control the EU’s external borders so that only refugees fleeing war and persecution, who have a legitimate right to seek asylum, can enter and potentially remain in the EU. The porous nature of the EU’s external borders has meant an unacceptable loss of control in the eyes of many EU citizens and has raised false hopes for irregular migrants trying to enter the Union. The control of the borders of the Schengen Area should be a collective effort of the EU and all Member States, coordinated by European Institutions with professional staff and with financial support provided to Member States at the EU’s periphery. Regaining control of the EU’s external borders is essential to preserve open internal borders.Second, beyond implementing the already agreed upon relocation of 160,000 refugees from Greece and Italy, the EU should develop a system which distributes a much larger number of refugees across the Union, directly from the hotspots in the EU and the neighbouring counties such as Turkey, Jordan or Lebanon. Member States not willing to host refugees themselves could choose to make a primarily financial contribution to the system. A Migration Solidarity Fund should be created to manage this compensatory system. Turkey’s efforts to reduce the crossings in the Aegean Sea should be matched by a willingness among EU Member States to take in refugees in an orderly manner. The Conclusions from the European Council seem to move in the right direction in this regard.The third measure should be to improve, standardize and speed up the processes to determine asylum applications. The sooner refugees know whether they can stay, the more energy can be invested in their integration into host countries’ societies and in family reunions. The sooner a decision is taken, the fairer and more feasible it is to send back those whose requests are refused in full respect of international law and human rights. And EU members cannot afford to have vastly different standards in granting asylum status. Under international law, there can be no limit set on the number of those eligible to request asylum.As a fourth measure, we recommend expanding efforts at the EU level to improve the living conditions of refugees staying in countries close to their countries of origin. Many refugees want to return to their homes as soon as the situation becomes safe again. They should not be driven to start the hazardous journey to the European Union only because of unbearable conditions in the countries where they are currently sheltering.Last but not least, the EU and its Member States should work vigorously towards ending the violent conflicts that are the principal causes of the crisis. Europe must invest heavily in the Syria peace process, in particular. The EU must also raise the ambition and resources of its Neighbourhood Policy, with a focus on helping to stabilise the region and on improving the living conditions and economic opportunities in the Southern neighbourhood.But action is also required at the national level, especially in the EU countries where significant numbers of refugees have received or are expected to receive asylum. The distribution of refugees across municipalities and regions should be fair and should come with adequate support and resources from the national level, emphasising education and language training. The recognition of professional competences and support to enter the labour market should be available at a very early stage. Within our societies, we need a dialogue between refugees and the host society. It should be made clear that respect for human rights, democratic values and cultural norms is indispensable for a prolonged stay in the respective European host country.Coming from seven European countries, with different national policies and approaches to the refugee crisis, the foundations and think tanks of Vision Europe are working together to advance new ideas, to frame an informed debate and to emphasize the benefits of common European solutions to Europe-wide problems. Europe is strong enough to manage the migration challenges, but only if political leaders act now, act responsibly and use the resources at their disposal, including support for civil society working in this area. We must not leave the public space to populists and nationalists offering false promises. Only a European solution will be workable and sustainable.
