Methylarginine metabolites are associated with attenuated muscle protein synthesis in cancer-associated muscle wasting [Protein Synthesis and Degradation]

Cancer cachexia is characterized by reductions in peripheral lean muscle mass. Prior studies have primarily focused on increased protein breakdown as the driver of cancer-associated muscle wasting. Therapeutic interventions targeting catabolic pathways have, however, largely failed to preserve muscle mass in cachexia, suggesting that other mechanisms might be involved. In pursuit of novel pathways, we used untargeted metabolomics to search for metabolite signatures that may be linked with muscle atrophy. We injected 7-week–old C57/BL6 mice with LLC1 tumor cells or vehicle. After 21 days, tumor-bearing mice exhibited reduced body and muscle mass and impaired grip strength compared with controls, which was accompanied by lower synthesis rates of mixed muscle protein and the myofibrillar and sarcoplasmic muscle fractions. Reductions in protein synthesis were accompanied by mitochondrial enlargement and reduced coupling efficiency in tumor-bearing mice. To generate mechanistic insights into impaired protein synthesis, we performed untargeted metabolomic analyses of plasma and muscle and found increased concentrations of two methylarginines, asymmetric dimethylarginine (ADMA) and NG-monomethyl-l-arginine, in tumor-bearing mice compared with control mice. Compared with healthy controls, human cancer patients were also found to have higher levels of ADMA in the skeletal muscle. Treatment of C2C12 myotubes with ADMA impaired protein synthesis and reduced mitochondrial protein quality. These results suggest that increased levels of ADMA and mitochondrial changes may contribute to impaired muscle protein synthesis in cancer cachexia and could point to novel therapeutic targets by which to mitigate cancer cachexia.

Ascertaining the biochemical function of an essential pectin methylesterase in the gut microbe Bacteroides thetaiotaomicron [Metabolism]

Pectins are a major dietary nutrient source for the human gut microbiota. The prominent gut microbe Bacteroides thetaiotaomicron was recently shown to encode the founding member (BT1017) of a new family of pectin methylesterases essential for the metabolism of the complex pectin rhamnogalacturonan-II (RG-II). However, biochemical and structural knowledge of this family is lacking. Here, we showed that BT1017 is critical for the metabolism of an RG-II–derived oligosaccharide ΔBT1017oligoB generated by a BT1017 deletion mutant (ΔBT1017) during growth on carbohydrate extract from apple juice. Structural analyses of ΔBT1017oligoB using a combination of enzymatic, mass spectrometric, and NMR approaches revealed that it is a bimethylated nonaoligosaccharide (GlcA-β1,4-(2-O-Me-Xyl-α1,3)-Fuc-α1,4-(GalA-β1,3)-Rha-α1,3-Api-β1,2-(Araf-α1,3)-(GalA-α1,4)-GalA) containing components of the RG-II backbone and its side chains. We showed that the catalytic module of BT1017 adopts an α/β-hydrolase fold, consisting of a central twisted 10-stranded β-sheet sandwiched by several α-helices. This constitutes a new fold for pectin methylesterases, which are predominantly right-handed β-helical proteins. Bioinformatic analyses revealed that the family is dominated by sequences from prominent genera of the human gut microbiota, including Bacteroides and Prevotella. Our re-sults not only highlight the critical role played by this family of enzymes in pectin metabolism but also provide new insights into the molecular basis of the adaptation of B. thetaiotaomicron to the human gut.

Methylated PP2A stabilizes Gcn4 to enable a methionine-induced anabolic program [Metabolism]

Methionine, through S-adenosylmethionine, activates a multifaceted growth program in which ribosome biogenesis, carbon metabolism, and amino acid and nucleotide biosynthesis are induced. This growth program requires the activity of the Gcn4 transcription factor (called ATF4 in mammals), which facilitates the supply of metabolic precursors that are essential for anabolism. However, how Gcn4 itself is regulated in the presence of methionine is unknown. Here, we discover that Gcn4 protein levels are increased by methionine, despite conditions of high cell growth and translation (in which the roles of Gcn4 are not well-studied). We demonstrate that this mechanism of Gcn4 induction is independent of transcription, as well as the conventional Gcn2/eIF2α-mediated increased translation of Gcn4. Instead, when methionine is abundant, Gcn4 phosphorylation is decreased, which reduces its ubiquitination and therefore degradation. Gcn4 is dephosphorylated by the protein phosphatase 2A (PP2A); our data show that when methionine is abundant, the conserved methyltransferase Ppm1 methylates and alters the activity of the catalytic subunit of PP2A, shifting the balance of Gcn4 toward a dephosphorylated, stable state. The absence of Ppm1 or the loss of the PP2A methylation destabilizes Gcn4 even when methionine is abundant, leading to collapse of the Gcn4-dependent anabolic program. These findings reveal a novel, methionine-dependent signaling and regulatory axis. Here methionine directs the conserved methyltransferase Ppm1 via its target phosphatase PP2A to selectively stabilize Gcn4. Through this, cells conditionally modify a major phosphatase to stabilize a metabolic master regulator and drive anabolism.

In crystallo screening for proline analog inhibitors of the proline cycle enzyme PYCR1 [Metabolism]

Pyrroline-5-carboxylate reductase 1 (PYCR1) catalyzes the biosynthetic half-reaction of the proline cycle by reducing Δ1-pyrroline-5-carboxylate (P5C) to proline through the oxidation of NAD(P)H. Many cancers alter their proline metabolism by up-regulating the proline cycle and proline biosynthesis, and knockdowns of PYCR1 lead to decreased cell proliferation. Thus, evidence is growing for PYCR1 as a potential cancer therapy target. Inhibitors of cancer targets are useful as chemical probes for studying cancer mechanisms and starting compounds for drug discovery; however, there is a notable lack of validated inhibitors for PYCR1. To fill this gap, we performed a small-scale focused screen of proline analogs using X-ray crystallography. Five inhibitors of human PYCR1 were discovered: l-tetrahydro-2-furoic acid, cyclopentanecarboxylate, l-thiazolidine-4-carboxylate, l-thiazolidine-2-carboxylate, and N-formyl l-proline (NFLP). The most potent inhibitor was NFLP, which had a competitive (with P5C) inhibition constant of 100 μm. The structure of PYCR1 complexed with NFLP shows that inhibitor binding is accompanied by conformational changes in the active site, including the translation of an α-helix by 1 Å. These changes are unique to NFLP and enable additional hydrogen bonds with the enzyme. NFLP was also shown to phenocopy the PYCR1 knockdown in MCF10A H-RASV12 breast cancer cells by inhibiting de novo proline biosynthesis and impairing spheroidal growth. In summary, we generated the first validated chemical probe of PYCR1 and demonstrated proof-of-concept for screening proline analogs to discover inhibitors of the proline cycle.

Serum lipoprotein-derived fatty acids regulate hypoxia-inducible factor [Metabolism]

Oxygen regulates hypoxia-inducible factor (HIF) transcription factors to control cell metabolism, erythrogenesis, and angiogenesis. Whereas much has been elucidated about how oxygen regulates HIF, whether lipids affect HIF activity is un-known. Here, using cultured cells and two animal models, we demonstrate that lipoprotein-derived fatty acids are an independent regulator of HIF. Decreasing extracellular lipid supply inhibited HIF prolyl hydroxylation, leading to accumulation of the HIFα subunit of these heterodimeric transcription factors comparable with hypoxia with activation of downstream target genes. The addition of fatty acids to culture medium suppressed this signal, which required an intact mitochondrial respiratory chain. Mechanistically, fatty acids and oxygen are distinct signals integrated to control HIF activity. Finally, we observed lipid signaling to HIF and changes in target gene expression in developing zebrafish and adult mice, and this pathway operates in cancer cells from a range of tissues. This study identifies fatty acids as a physiological modulator of HIF, defining a mechanism for lipoprotein regulation that functions in parallel to oxygen.

The bacterial cell division protein fragment EFtsN binds to and activates the major peptidoglycan synthase PBP1b [Metabolism]

Peptidoglycan (PG) is an essential constituent of the bacterial cell wall. During cell division, the machinery responsible for PG synthesis localizes mid-cell, at the septum, under the control of a multiprotein complex called the divisome. In Escherichia coli, septal PG synthesis and cell constriction rely on the accumulation of FtsN at the division site. Interestingly, a short sequence of FtsN (Leu75–Gln93, known as EFtsN) was shown to be essential and sufficient for its functioning in vivo, but what exactly this sequence is doing remained unknown. Here, we show that EFtsN binds specifically to the major PG synthase PBP1b and is sufficient to stimulate its biosynthetic glycosyltransferase (GTase) activity. We also report the crystal structure of PBP1b in complex with EFtsN, which demonstrates that EFtsN binds at the junction between the GTase and UB2H domains of PBP1b. Interestingly, mutations to two residues (R141A/R397A) within the EFtsN-binding pocket reduced the activation of PBP1b by FtsN but not by the lipoprotein LpoB. This mutant was unable to rescue the ΔponB-ponAts strain, which lacks PBP1b and has a thermosensitive PBP1a, at nonpermissive temperature and induced a mild cell-chaining phenotype and cell lysis. Altogether, the results show that EFtsN interacts with PBP1b and that this interaction plays a role in the activation of its GTase activity by FtsN, which may contribute to the overall septal PG synthesis and regulation during cell division.

Inhibition of oxidative metabolism by nitric oxide restricts EMCV replication selectively in pancreatic beta-cells [Enzymology]

Environmental factors, such as viral infection, are proposed to play a role in the initiation of autoimmune diabetes. In response to encephalomyocarditis virus (EMCV) infection, resident islet macrophages release the pro-inflammatory cytokine IL-1β, to levels that are sufficient to stimulate inducible nitric oxide synthase (iNOS) expression and production of micromolar levels of the free radical nitric oxide in neighboring β-cells. We have recently shown that nitric oxide inhibits EMCV replication and EMCV-mediated β-cell lysis and that this protection is associated with an inhibition of mitochondrial oxidative metabolism. Here we show that the protective actions of nitric oxide against EMCV infection are selective for β-cells and associated with the metabolic coupling of glycolysis and mitochondrial oxidation that is necessary for insulin secretion. Inhibitors of mitochondrial respiration attenuate EMCV replication in β-cells, and this inhibition is associated with a decrease in ATP levels. In mouse embryonic fibroblasts (MEFs), inhibition of mitochondrial metabolism does not modify EMCV replication or decrease ATP levels. Like most cell types, MEFs have the capacity to uncouple the glycolytic utilization of glucose from mitochondrial respiration, allowing for the maintenance of ATP levels under conditions of impaired mitochondrial respiration. It is only when MEFs are forced to use mitochondrial oxidative metabolism for ATP generation that mitochondrial inhibitors attenuate viral replication. In a β-cell selective manner, these findings indicate that nitric oxide targets the same metabolic pathways necessary for glucose stimulated insulin secretion for protection from viral lysis.

Coronavirus infection and PARP expression dysregulate the NAD metabolome: An actionable component of innate immunity [Molecular Bases of Disease]

Poly(ADP-ribose) polymerase (PARP) superfamily members covalently link either a single ADP-ribose (ADPR) or a chain of ADPR units to proteins using NAD as the source of ADPR. Although the well-known poly(ADP-ribosylating) (PARylating) PARPs primarily function in the DNA damage response, many noncanonical mono(ADP-ribosylating) (MARylating) PARPs are associated with cellular antiviral responses. We recently demonstrated robust up-regulation of several PARPs following infection with murine hepatitis virus (MHV), a model coronavirus. Here we show that SARS-CoV-2 infection strikingly up-regulates MARylating PARPs and induces the expression of genes encoding enzymes for salvage NAD synthesis from nicotinamide (NAM) and nicotinamide riboside (NR), while down-regulating other NAD biosynthetic pathways. We show that overexpression of PARP10 is sufficient to depress cellular NAD and that the activities of the transcriptionally induced enzymes PARP7, PARP10, PARP12 and PARP14 are limited by cellular NAD and can be enhanced by pharmacological activation of NAD synthesis. We further demonstrate that infection with MHV induces a severe attack on host cell NAD+ and NADP+. Finally, we show that NAMPT activation, NAM, and NR dramatically decrease the replication of an MHV that is sensitive to PARP activity. These data suggest that the antiviral activities of noncanonical PARP isozyme activities are limited by the availability of NAD and that nutritional and pharmacological interventions to enhance NAD levels may boost innate immunity to coronaviruses.

Priorities for implementing Ethiopia's national dialogue

Priorities for implementing Ethiopia's national dialogue 11 May 2022 — 1:00PM TO 3:00PM Anonymous (not verified) 3 May 2022 Online

Experts discuss challenges and priorities in shaping an inclusive and effective national dialogue in Ethiopia.

Ethiopia is grappling with numerous contentious national issues – not least persistent conflict in several parts of the country – which underscore the need for large-scale dialogue and reconciliation efforts to address the country’s deep-rooted societal and political divisions. Ethiopia’s newly established National Dialogue Commission – whose 11 commissioners were appointed in February 2022 – has begun a four-phased process of preparations for a dialogue, with its initial stage focused on stakeholder engagement and local knowledge mobilization.

There are major challenges, however, in ensuring inclusivity amidst ongoing conflict and questions on how a country-wide process will sit alongside local dialogue initiatives and wider mediation and peacebuilding efforts. Linking the process to constitutional bodies will also be an important priority to ensure dialogue outcomes are effectively implemented.

At this public event, panellists will exchange perspectives on how to shape an effective national dialogue in Ethiopia, including priorities for building a credible National Dialogue Commission and the roles and responsibilities of other national, regional and local-level actors. They will also discuss key implementation mechanisms and long-term priorities for trust-building and cultivating a conducive environment for inclusive dialogue.

This webinar is part of a series of events and outputs on Ethiopia’s political transition.

This event will also be broadcast live on the Chatham House Africa Programme’s Facebook page.

Enhancing the role of women in peacebuilding and politics in Ethiopia

Enhancing the role of women in peacebuilding and politics in Ethiopia 29 June 2022 — 1:00PM TO 2:30PM Anonymous (not verified) 16 June 2022 Online

Panellists discuss the priorities for promoting the agency of women in politics and peacebuilding in Ethiopia and approaches for combatting gender-based discrimination and violence.

The war in northern Ethiopia and conflicts elsewhere have disproportionately affected women and girls – including through the infliction of physical and sexual violence, the heightened impacts of displacement and disruptions to education, and the co-option of women’s experiences in narratives by aggressors of conflict.

Hard-won political gains in women’s rights have been undermined and deep-rooted gender inequalities exacerbated. Despite this, women remain central actors in politics, as well as in conflict resolution and mediation efforts. However, more needs to be done to promote the security and inclusion of women in finding sustainable solutions for Ethiopia’s long-term recovery and to institutionalize reforms for gender equity and development.

At this public event, panellists will discuss the priorities for improving women’s participation and equality in public decision-making in Ethiopia and how to strengthen the implementation of legislation on women’s rights. They will also discuss what societal shifts and approaches are needed to combat gender-based discrimination and violence and to promote the agency of women in peacebuilding.

What will authorizing the return of US troops mean for Somalia?

What will authorizing the return of US troops mean for Somalia? Explainer Video aboudiaf.drupal 17 June 2022

Ahmed Soliman examines what the reintroduction of US military means for Somalia.

He says the strategy remains to try and reduce al-Shabaab’s threat, suppress its ability to carry out operations, and target its senior leadership.

There is more of a recognition now that the focus needs to be on restoring an effective security sector within Somalia and ensuring their forces are ready, but this also requires better coordination between the federal government and federal member states which it is hoped will happen in this new administration.

Will Africans’ calls for better democracy be met?

Will Africans’ calls for better democracy be met? The World Today mhiggins.drupal 29 July 2022

Voters want the continent’s ageing leaders to step aside to usher in a new age of political engagement and robust democracy, say the experts of Afrobarometer.

Across Africa, recent years have been marked by both encouraging democratic highs and troubling anti-democratic lows. Notable advances from last year include the Gambia’s successful presidential election, a ruling-party transition in Zambia and the first democratic transfer of power in Niger. In the lead up to this, add Malawi’s retake of its flawed presidential election in 2020 and an earlier succession of oustings of long-serving autocrats in Sudan, Zimbabwe and the Gambia. 

Contrast these gains, though, with setbacks elsewhere, including increasing restrictions on opposition parties in Benin, Senegal and Tanzania; the use of violence and intimidation during elections in Côte d’Ivoire and Uganda; and military coups, with the latest in Burkina Faso this year and last year in Chad, Mali, Sudan and Guinea.


These contradictory developments join dire warnings from experts that democracy is losing ground on the continent. But what can we learn about the state of democracy on the continent from Africans themselves?

Afrobarometer, a pan-African, non-partisan research network, has been surveying people about their views on democracy, governance and quality of life for more than 20 years. After interviewing nearly 50,000 citizens across 34 countries during Afrobarometer Round 8, which spans 2019-2021, we find that despite the efforts of some leaders to undermine democratic norms, Africans remain committed to democracy and democratic institutions.

They believe that the military should stay out of politics, that political parties should freely compete for power, that elections are an imperfect but essential tool for choosing their leaders, and that it is time for the old men who cling to power to step aside.

But their political reality falls short of these expectations. The perception of widespread and worsening corruption is particularly corrosive, leaving people increasingly dissatisfied with political systems that are yet to deliver on their aspirations to live in societies that are democratically and accountably governed. And although citizens find myriad ways to voice their concerns, they feel that their governments are not listening.

Simply put, Africans want more democratic and accountable governance than they think they are getting.

Africans’ democratic aspirations

Over the past decade, democracy watchers have been alarmed by declining trends in Africa. Concerns have been exacerbated in the past two years as some governments have taken advantage of the Covid pandemic to limit freedoms, restrict fair campaigning or postpone elections. Activists fear that supposedly temporary rollbacks in hard-won governance reforms could become permanent.

But for the most part, African citizens remain committed to democracy and democratic institutions. Across 30 countries that Afrobarometer has surveyed consistently since Round 5 (2011–2013), most indicators are strong and quite steady.


For example, seven in 10 Africans say that ‘democracy is preferable to any other kind of government’. While this is down modestly from 73 per cent a decade ago, more specific indicators seem to affirm popular commitment to democracy. Large and steady majorities consistently reject authoritarian alternatives, including one-person or ‘strongman’ rule (82 per cent), one-party rule (77 per cent) and military rule (75 per cent), which is clearly rejected even in many of the countries rocked by recent military coups.

Africans also express strong support for a limit to presidential terms, a feature of democratic governance that researchers and activists argue nurtures political participation, demonstrates that change via the ballot box is possible, and reduces the risk of personality cults, authoritarianism, corruption and coups. Across 34 countries, an average of 76 per cent favour limiting their presidents to two terms, including a majority (54 per cent) who ‘strongly’ support this rule. Term limits enjoy majority support in every surveyed country. 

The public’s democratic commitment is undergirded by strong and in some cases growing support for core democratic institutions. Support for multiparty competition and parliamentary oversight of leaders remains steady, while expectations that governments should be accountable to the courts have increased significantly over the past decade.

In addition, growing numbers of people say it is more important to have a government that is accountable to the people rather than one that just ‘gets things done’, an especially strong indicator of deepening commitment to democratic norms among citizens. 

Trouble at the polling booth

Elections remain a central, though controversial, institution of democracy for Africans. They have served as the foundation for real change, as in Zambia last year. But in other cases, such as Uganda’s January 2021 poll, they have been marred by violence and human rights abuses, as well as the weaponization of Covid to justify restrictions on campaigning.

The public is also sceptical about the capacity of elections to bring about real change: fully 50 per cent say they do not think elections are effective in enabling voters ‘to remove from office leaders who do not do what the people want’.

At the same time, large majorities report positively on their country’s election environment. Asked about their most recent election, at least eight in 10 say they did not observe intimidation (87 per cent) or interference (81 per cent) by security forces and did not fear violence (80 per cent).

We must keep in mind that these encouraging averages can obscure deep problems in some countries. For example, while only 3 per cent of Namibians say votes are ‘often’ not counted fairly, between a quarter and one-third cite inaccurate counts as a frequent problem in Zimbabwe, Sudan and Gabon. 


In addition, confidence in the fairness of the media environment is drastically lower, on average just 36 per cent.

But perhaps most importantly, almost nine in 10 Africans (87 per cent) say they are free to vote as they choose, including sizeable majorities in every surveyed country. And a solid majority of 63 per cent rate their most recent election as completely or mostly free and fair. 

All of this may help to explain still-strong support for competitive elections as the best system for selecting leaders. A robust three-quarters confirm their commitment to elections, though this has fallen slightly over the past decade, probably reflecting disillusionment with electoral processes that are too often torn by violence and produce contested results. 

A growing number of people may also be recognizing that elections, especially poor-quality ones, are not enough to guarantee democracy and better governance, and that a healthy democracy must include such other features as government accountability, respect for the rule of law, responsiveness and citizen participation.

The ‘democratic disappointment’ gap

To what extent does political reality align with Africans’ democratic aspirations? Our findings suggest that it is falling well short of expectations.

While a slim majority has steadily reported that their country is a ‘full democracy’ or one ‘with minor problems’ over the past decade, satisfaction, however, has dropped to 43 per cent in that time. 

What explains this growing dissatisfaction? Other indicators of democratic supply offer some clues. While ratings of election quality have held steady, favourable public assessments of presidential accountability to parliament and to the courts have both declined.

The rising scourge of corruption

But one of the most significant driving factors may be burgeoning corruption, a trend that appears to parallel declining democratic satisfaction. On average across 34 countries, around six in 10 say both that corruption in their country increased over the past year, and that their government is doing a poor job of controlling it.

These perceptions matter. Over time, when perceptions of corruption rise or fall, levels of dissatisfaction with democracy tend to follow suit. 

In South Africa, dissatisfaction with democracy grew steadily alongside scandals involving President Jacob Zuma, and has continued to rise under his successor, Cyril Ramaphosa, whose office has been tainted by ‘Farmgate’ and a major Covid-relief scandal. The ‘Fishrot’ scandal in Namibia has had similar consequences.

Are governments listening?

African citizens are raising their voices, calling on their governments to fulfil their democratic aspirations. Since April 2017, the Carnegie Endowment for International Peace has recorded more than 70 episodes in 35 African countries of protests focused on issues ranging from demands for democracy in eSwatini to resisting police brutality, presidential third-term attempts and Covid restrictions. 

Citizen participation and government responsiveness are cornerstones of democracy. But are governments listening?

Voting is the most obvious and popular way for citizens to express themselves, and Africans take advantage of this opportunity. Two-thirds said they voted in their most recent national election. But elections occur only occasionally, and they force individuals to compress a wide array of views into very few choices. How do Africans find their voice during the long intervals between elections?

Many invest in personal efforts to act as agents of change. In fact, nearly half say they joined with others to raise an issue at least once in the past year, and a third contacted a political leader. A quarter report they acted with others to request government action. Less common but still important modes of engagement include asking for help from or lodging a complaint with government, contacting the media, and joining a demonstration.


These robust levels of citizen engagement suggest that people feel they can make a difference. Unfortunately, decision-makers aren’t always receptive or responsive to citizen voices. Less than a quarter of people think local government officials listen to them – and even fewer think their members of parliament do. 

What is more troubling is that fully two-thirds say they are at risk of retaliation or some form of negative consequences if they take action by reporting incidents of corruption. 

Lack of government responsiveness and respect for popular voices may have direct implications for both citizen engagement and citizen satisfaction. For example, we find that people are more likely to contact leaders or take other actions to solve problems if they believe that government officials respect and listen to them; that they will get a response if they raise an issue; and if they do not need to fear retaliation. 

Similarly, when we compare country averages for government responsiveness to the percentage of citizens who are satisfied with democracy, we again find positive associations. 

When governments are responsive, citizens are more likely to engage in addressing community needs and to be satisfied with their political system and optimistic about the future. Respectful and responsive governance has the potential to spur citizen action to solve critical development challenges – and may be the cure for what ails democracy.

Now is the moment to launch an African vaccine industry

Now is the moment to launch an African vaccine industry The World Today mhiggins.drupal 31 July 2022

The continent plans to make 60 per cent of its vaccines by 2040. After the failure of the world to help in the pandemic, it’s high time, says Ngozi Erondu.

The lack of an African vaccine industry has been a glaring concern for decades. Before the pandemic, 99 per cent of Africa’s vaccines were manufactured outside the continent. As well as endangering the lives of millions, this situation has inhibited social and economic progress on the continent.

In response, the Africa Centres for Disease Control and Prevention (Africa CDC) has undertaken an ambitious plan, outlined in the Partnerships for African Vaccine Manufacturing (PAVM) Framework for Action, to develop the nascent African vaccine manufacturing sector into an end-to-end industry by 2040. The framework aims to raise the share of African-manufactured vaccines used across the continent to 60 per cent by 2040, or the equivalent to up to 1.7 billion doses annually.

Seven of every 10 vaccines used in Africa are currently donated through Gavi, the Vaccine Alliance. Most are administered within childhood immunization programmes and are largely manufactured either in India, or by  multinational vaccine manufacturers in North America or Japan.

Vaccine donations have inhibited the development in Africa of vaccines and other countermeasures against diseases.


Though the Ebola virus was discovered in Central Africa in 1976, vaccine development was not adequately funded until it emerged in Europe in 2014. Human monkeypox resurfaced in Nigeria in 2017, yet the global Coalition for Epidemic Preparedness Innovations only targeted it for vaccine development in July this year.

The pandemic highlighted Africa’s fatal dependency on imported vaccines. Only 20 per cent of Africans are fully vaccinated against Covid-19, due to the failure of countries in the Global North to ensure the equitable distribution of vaccines via the COVAX facility to 40 per cent of the world’s most vulnerable people. 

The pandemic also confirmed that Africa could not rely on fellow states of the Global South. At the height of the Delta variant outbreak in early 2021, India halted vaccine exports to Africa, where only 1.5 per cent of the population had at that time received any vaccine doses.

After decades of discussions, there are signs that Africa could soon succeed in creating its own vaccine industry. First, the 55-member African Union is in the process of establishing the African Medicines Agency, a regional regulatory body. 
 

‘The new public health order’

Additionally, the African Export-Import Bank and African Development Bank (AfDB) have established a foundation to provide financial and strategic support for the development of the pharmaceutical industry and the consolidation of regional vaccination programmes in Africa (the foundation would potentially negotiate intellectual property rights and licensing issues but that remains to be seen).

Second, studies show there is an emerging middle class in Africa. In a 2011 report by the AfDB, this was estimated at some 56 million households. Potentially, this means many people will be able to buy vaccines and medicines made in Africa.

About a third of African countries currently pay for their vaccine needs. According to PAVM forecasts, the value of the total African market could reach between $3 billion and $17 billion by 2040.

The recent entry into effect of the African Continental Free Trade Area should also prove conducive to African vaccine development. Through economic integration, free movement and harmonized regional standards, countries that invest in their biopharmaceutical and medical technology sectors may attract employees, regional and international businesses, and investment. Further, the pandemic has encouraged people to relocate to countries with, or planning for, universal healthcare.

Building an African pharmaceutical industry from the ground up could take much longer than two decades and cost tens of billions of dollars. Nevertheless, the moment seems ripe, and timely support has been forthcoming from influential regional actors, including Rwandan President Paul Kagame, South Africa’s Cyril Ramaphosa, and private sector business executives, including the Zimbabwean-born billionaire Strive Masiyiwa.

With a pandemic treaty embedding equity in prevention, preparedness and response some way off, and given the limitations surrounding the recent World Trade Organization compromise on the TRIPS waiver – which temporarily waives Covid-19 vaccine patent protections for poorer countries – it is doubly important for Africa to build up its own pharmaceutical industry and emergency systems. 

With a pandemic treaty some way off, it is important for Africa to build up its own pharmaceutical industry 


In 2021, John Nkengasong, then director of Africa CDC, wrote of the necessity of a post-pandemic ‘new public health order’ for Africa. Such a change may threaten the global health organizations, industries and institutes who derive payment from ‘saving Africa’ during emergencies. Additionally, through strengthening Africa CDC, other actors such as the World Health Organization may find that they have a diminished strategic role on the continent.
 
While Africa should not dismiss these valuable and long-standing partnerships, it must take the opportunity to advance its interests and to assume leadership in this important area.

Review: the rise of Africa’s superwomen

Review: the rise of Africa’s superwomen The World Today mhiggins.drupal 1 August 2022

From foster care in England to colonialism’s legacy in Zimbabwe, this set of essays on race, feminism and identity is searingly honest, says Masiyaleti Mbewe.

Black and Female
Tsitsi Dangarembga, Faber, £9.99

The 1988 novel Nervous Conditions by the Zimbabwean author Tsitsi Dangarembga is considered one of Africa’s finest literary exports. It won the Commonwealth Writers’ Prize and alongside The Book of Not (2006) and This Mournable Body (2018), shortlisted for the 2020 Booker Prize, forms a trilogy of semi-autobiographical novels that grapple with the gendered colonial oppression of young black girls and women from Southern Rhodesia through to Zimbabwe. 

In Black and Female, Dangarembga continues the interrogation of these intersections in an unflinchingly honest and personal, if occasionally dense, collection of essays. Along the way, she examines the sheer magnitude of colonialism’s effects on African people, and how they ripple through her early childhood in England and her formative years as a writer, filmmaker and feminist activist in post-independence Zimbabwe.

‘Writing While Black and Female’

In 1961 Dangarembga’s parents relocated from Southern Rhodesia to the UK. While they worked and studied in London, they put their two-year-old daughter, her older brother and, later, her younger sister into private foster care in Dover, Kent (as many Africans did – a fact that was new to me). The first essay, ‘Writing While Black and Female’, takes a painful look at the four years she spent with her foster parents, Mummy-Gran and Daddy Henry. 

Blackness, she learned in those years, was a consequence of her non-whiteness. So Dangarembga writes of the momentary elation she felt when a stranger addressed her as a ‘lovely little piccaninny’, giving her ‘a category I could wield against the void of no longer being’. To cope with this sort of racialization and her abandonment, the young Dangarembga turned to disassociation and self-harm. 

Blackness is a condition imposed on me, rather than being an experienced identity

Tsitsi Dangarembga

As she writes: ‘Blackness is a condition imposed on me, rather than being an experienced identity.’ Instead of ‘black’ people, therefore, Dangarembga prefers the term ‘highly melanated people’. It is a resonant phrase, highlighting the inherently ridiculous nature of racism.

Dangarembga’s ‘Africanness’ shifts into focus upon her return to Rhodesia in 1965. At first, other children refused to play with her and her siblings, calling them ‘varungu’ (white people). As she describes it: ‘The dance of my identities … became frenetic’. 

In ‘Black, Female and the Superwoman Black Feminist’, the second essay, Dangarembga is adamant about the urgent necessity of a black feminist practice that is centred on action to provide real, material change. Along the way, she makes a distinction – a slightly uneasy one to my mind – between the patriarchy that western colonization imposed, based on private ownership, and the patriarchy of pre-colonial African society with its foundations in kinship that devolved power to an extent.

Dangarembga’s discussion of a more accommodating, pre-colonial patriarchy is nuanced, but it jars a little


‘Hence women could and did become rulers and warriors, and royal spirit mediums called mhondoro,’ Dangarembga writes approvingly. She is making a nuanced point; but the idea of a more accommodating sort of patriarchy jars a little nonetheless.

While independence may have arrived for Zimbabwe more than 40 years ago, Dangarembga argues strongly that the subjugation of women and feminists at the hands of the ruling Zanu-PF government continues as an extension of colonial rule. Indeed, beyond Zimbabwe, black feminists remain ‘a small, often embattled group’ across Africa, believes Dangarembga. 

Pointedly, she criticizes global feminism’s greater focus on optics than on practical activism

 

As a young black feminist who is part of this ‘small, embattled group’, I should say we have been able to foster large communities digitally and otherwise to work around the hostility we are often faced with. Despite internet shutdowns and restrictions, we resist – an act Dangarembga encourages.  

Resistance, she says, starts with establishing community despite these difficulties. At the nucleus of Dangarembga’s argument is the ‘superwoman’ of the essay’s title, the African woman who doesn’t require external factors to be inspired to action but who continuously draws on what Dangarembga calls ‘internal agency’ that derives from ‘an unrelenting fight for survival and dignity’.

Pointedly, she criticizes global feminism’s greater focus on optics than activism in the practical sense. One only has to observe the performative allyship and ‘Instagram activism’ rampant on the internet today to see her point.
 

The complexities of decolonization

In the final essay, ‘Decolonization as Revolutionary Imagining’, Dangarembga turns her gaze upon the ‘highly stratified’ European societies that outsourced their violent inequality to their empires and ‘the work of decolonization’. However, decolonial discourse is complex, and it is here that the writing occasionally gets bogged down. Fewer recommendations with more elaboration perhaps would have helped.

She herself acknowledges the difficulties of decolonization. Centuries of the Enlightenment and its logic of ‘racism, slavery, genocide and colonization’ are hard to uproot ‘whatever one’s melanin concentration’, she writes.

Nevertheless, Dangarembga concludes with the radical determination to dismantle that is evident throughout this searing yet hopeful collection: ‘The trajectory of current and future generations depends on that uprooting.’

The online media changing African news

The online media changing African news The World Today mhiggins.drupal 2 August 2022

Africa’s news sites are gripping audiences with digital innovation and bold directions. Helen Fitzwilliam talks to editors at three platforms.

Lydia Namubiru
News editor of ‘The Continent’ (South Africa)

At the start of the pandemic, we realized a lot of fake news was being shared on WhatsApp. So, The Continent chose to launch on that platform to insert some real journalism in a way that could easily be shared. We now have about 100,000 readers across Africa and the rest of the world, but we had to dramatically change the way we write and edit stories: to compete with the likes of Twitter and Instagram, we try to keep stories tight at 300 words. 

There’s a real variety. We can run an investigation into corruption in the Democratic Republic of the Congo a week after a front page on the fashion designer who dresses Africa’s ‘big men’ [powerful leaders]. We cover feminist issues, the backlash against LGBT people in Ghana; we’ve had the Namibian first lady talking to us about misogyny. These are not the sort of topics a typical African newspaper is going to lead with.

There are refugees in camps doing data operations being paid a pittance to help create multimillion-dollar systems for US companies – that’s a future issue


With a story such as Ukraine, the war’s impact on the cost of living has been the most obvious angle for us. It has driven countries such as Malawi into crisis, forcing a devaluation of the currency.
 
As for the future, we see two issues looming. Workers’ economic rights and their treatment by multinationals will be a big story. There are refugees in camps in Kenya working in data operations and being paid a pittance to help create huge, potentially multimillion-dollar systems for US companies. 

Second, Africa has the world’s youngest population and the oldest leaders, so this will likely lead to activism and protests. The young are exposed to the global village, so they want different things and have different values. They speak a completely different language their leaders do not understand. It will be an interesting conflict, but could lead to real violence. 


John Githongo
Editor of ‘The Elephant’ (Kenya)

We set up this platform four years ago. Due to political and commercial pressures, mainstream media wasn’t doing much critical reporting. We have between 30,000 and 80,000 readers a week, the majority of them in Africa. 

The digital space reaches a completely different demographic. When The Elephant started, it was 80 per cent male and over 40, but we have gained more younger people and more women. Now it is 60 per cent men, 40 per cent women and that is something we have been working at. 

Our editorial approach is that as long as a piece has a strong argument and fits into our pan-African brief, we will publish it – even if we don’t agree with it.

The conflicts in Ethiopia and parts of the Sahel make the war in Ukraine pale in comparison. So many people have died in Ethiopia or been displaced and now we have the onset of a famine after four years of failed rain. During the 1960s and 1970s, when the Cold War found its way on to African soil, millions of people died – so there is caution about getting involved in a European fight.

Ahead of the election, we are exposing those trying to change the level of debate with reputation-laundering


There is always a lot of fake news around during elections. But people are beginning to be more sceptical. We go after those who attempt to change the level of debate with reputation-laundering and try to expose their actions. 
 
The future of democracy is going to be a big issue. When Africans were watching the attack on the US Capitol last year, they were hoping it was not a Black Lives Matter protest, which could have resulted in a ‘blackbath’. As soon as they saw the white guys wearing horns, people laughed with relief. 

There is an ongoing recalibration of Africa’s geopolitical relations with the rest of the world. A poll released in June showed China has overtaken the United States as the foreign power having the biggest positive influence in Africa in the eyes of young people across the continent. The younger generation is writing its own narrative. 


Wale Lawal
Editor of ‘The Republic’ (Nigeria)

Nigerian audiences are increasingly online and tend to read both local and international publications. They also know that the issues they care about are either under-reported or reported at lower quality levels. 

At The Republic, we provide political journalism that tends to require high levels of expertise. Yet online audiences also prioritize engagement: it is not enough for an issue to be important, it also needs to be interesting.

Some topics we have covered that Western media tend not to include how people experience blackness in different parts of the world; the waves of mostly female-led and youth-led movements rising up against autocratic governments across Africa; and relationships between countries within Africa itself. In the early days of the pandemic, we launched a Covid-19 and Africa series, having noticed a glaring lack of African expert voices in global media.
 
We also cover Africa’s evolving relations with Russia. Whenever we encounter a story like Russia’s invasion of Ukraine, the first thing we always ask ourselves is what missing voice can we add to the current discussion? All we were reading about after the invasion was how neighbouring countries were opening their borders and their homes to Ukrainians. Most people saw only that. 

We knew that around 15,000 Africans were studying in Ukraine when Russia invaded, but their voices were missing from the discussion


But we knew that around 15,000 Africans were studying in Ukraine, that Africans routinely face harsh treatment at international borders, and that clearly their voices were missing from the discussion.

With fake news and information gaps on social media, our usual approach is to develop expert-led columns and circulate these as widely as possible.

Our next mission is to think about the role that independent media can play in supporting democracies, such as by increasing voter turnout. During the last election in Nigeria, less than 35 per cent of those who registered to vote eventually did so.

Not the same old African story

Not the same old African story The World Today mhiggins.drupal 2 August 2022

Nollywood studio boss Mo Abudu and author Dipo Faloyin discuss how Africans are redefining how the world sees them.

Mo Abudu
EbonyLife’s latest TV drama series, Blood Sisters, was in Netflix’s global top 10. It’s a thriller and it may be slightly melodramatic because we Nigerians are melodramatic. But it deals with universal themes. Nigerians are no different to anyone else. I want EbonyLife productions increasingly to appeal to anyone in the world, even if it’s in our language. Oloture, one of our films, was about human trafficking. It was all done in pidgin English and subtitled. I watch a lot of Korean dramas and Spanish dramas that are subtitled. A good story is a good story.

Dipo Faloyin
The influence that African countries have had on the West, from music, food and film to literature, science and technology, is something people find difficult to take seriously. So, it’s good to see Netflix and other production companies take it more seriously. How has your discussion with them changed since the early days?

Mo Abudu
I have been going to an entertainment market in Cannes called Mipcom for about 12 years, and at first no one had any interest in African content. So, we focused on doing local content for local markets. Now, different communities around the world want representation in content that speaks to them. Specific countries are also saying to streamers: ‘What’s your local content strategy?’ 

I’m not telling broadcasters to commission original African content as a charity project – they can make money from this

Mo Abudu


Netflix was the first of the streamers to come into Africa, and it now has an Africa office. Amazon has also made inroads recently. Disney is arriving. In the United States and Britain, they just need to maintain subscriber numbers, but real growth for them is going to be in Asia and Africa. 

I’m not telling broadcasters or distributors to commission original African content as a charity project – they can make money from this. Within five days of launch, Blood Sisters registered 11 million hours of viewing on Netflix around the world. It was made on a budget five times smaller than productions outside Africa. But we need to be among the gatekeepers, too. 

Moving beyond Hollywood

Dipo Faloyin
The challenge that many creatives across Africa have is that people [elsewhere] don’t necessarily feel like they relate to this continent. They see ‘Africa’ and its cultures as very distant. Instead of intricate, specific stories, simple stories of simple people have been pushed about the continent. 

I still get asked questions like, ‘But, what should we do about Africa’s problems?’ My response is, ‘Stop seeing Africa as just a problem.’ 

A still from the Nigerian film ‘Oloture’, released in 2022, which deals with issues of human trafficking.

Mo Abudu
I was speaking at the Qatar Economic Forum recently and the panel started off talking about the ‘problems of Africa’ – and I had to jump in and say, ‘I get you guys talking about the problems, I’m not an economist, I’m just an entrepreneur, but from an entrepreneurial perspective, we have resources – like cobalt from the Democratic Republic of Congo that’s in all of our mobile phones.’ 

The problem is, we ship out all our resources and by the time they come back to us, they are 10-times more expensive than we can afford. I keep saying that they need to know they need us as much as we need them.
 
Dipo Faloyin
There are certainly issues within the continent like there are everywhere else; but more accurate stories will help people have a better sense of the context in which so many communities and their lives have been built up. 

Mo Abudu
The West doesn’t seem to have any interest in making films about Africa unless it’s about the worst of Africa: the slave trade, the Rwandan genocide, blood diamonds. That seems to be what has defined us. 

Dipo Faloyin
If you ask most people around the world to close their eyes and picture Africa, two images will come up: safari, and poverty and strife. Until the age of 12, I grew up in Lagos, a metropolis with no wild animals running around. There are slums, of course, but also traffic, shopping centres and overpriced restaurants. 

Writers who pitch ideas to Vice.com where I work often still don’t differentiate African countries. They’ll say, ‘There’s been a coup in Mali. Why can’t Africa get its head around democracy?’, and I remind them a small minority of countries on the continent is under any form of authoritarian rule. 

It’s frustrating that this perception hasn’t changed. For us to break through we need big cultural institutions – Hollywood, museums, literature – to allow people from across the regions to tell these stories. We are rarely portrayed as protagonists and forward thinkers. But I’m excited for the future.

A new vision for African agency in sustainable development

A new vision for African agency in sustainable development Expert comment LJefferson 18 October 2022

Change is necessary not only in global economic structures and attitudes – but in African governance too.

The conventional notion that Africa is mostly a consumer of norms and practices designed by the Global North has been repeatedly challenged and is increasingly being debunked. Increased African agency in international affairs is today a well-established and documented reality. But Africa’s influence still does not match the scale of the challenges that it faces on its pathway to sustainable development. 

Pushing for African agency in sustainable development also warrants a critical assessment of how ‘sustainable development’ should be defined, and how it can be achieved in terms of actual poverty reduction and real improvement in the lives of local poor Africans. Sustainable development has been a political catchphrase for over 30 years – but a genuine transition towards sustainability has yet to begin.

African agency today

Historically, there have been structural limitations on the agency of African stakeholders to shape development pathways. Chief among them, donor-recipient power dynamics have persistently promoted dependency and sustained institutional corruption. Many African countries are also challenged by economic incentives and infrastructure that have favoured the market demands and supply chains of former colonial powers, which largely remain reliant on natural resource extraction, and are marked by limited investment in value-addition activities and technology development.

Donor-recipient power dynamics have persistently promoted dependency and sustained institutional corruption.

Today, however, African agency is being exerted in a more assertive fashion. The African Union (AU), individual African states, civil society, the private sector and eminent and ordinary persons are all displaying Africa’s agency in steering global sustainable development priorities, namely by proposing their own development agenda, The African Union Agenda 2063, adopted in 2013. This was followed by the UN Sustainable Development Goals (Agenda 2030), which in many ways mirror Agenda 2063 – a clear demonstration of the influence of Africa in the global arena. 

Agenda 2063 is a strategic roadmap for Africa ‘to build an integrated, prosperous and peaceful Africa, driven and managed by its own citizens and development goals representing a dynamic force in the international arena’. Prepared following a broad-based participatory consultation, it advocates for inclusion and empowerment and provides an excellent vision for African countries and African people. The SDGs address several of the key shortcomings of their predecessor – the MDGs – and incorporate a broader and more transformative agenda that more adequately reflects the complex challenges of the 21st century and the need for structural reforms in the global economy and governance norms.

In international forums on sustainable development, African countries are increasingly using their collective voice to change the discourse on how development can and should be done. For instance, by championing innovative solutions for carbon markets, African policy leaders are enabling access to climate finance for development while preserving Africa’s natural wealth.

In the post-COVID era, championing investments in and leadership of Africa’s global health architecture demonstrates a desire that in the next pandemic, Africa CDC, AMA and continental manufacturers will play leading roles in determining Africa’s public health strategy and implementation.

In trade, building on the groundwork led by the regional economic commissions, the AfCFTA will catalyse and scale regional integration, trade and cooperation, leading to promising new modes of supply chain and self-sufficiency.

Encouraging signs, but persistent shortcomings

Encouraging signs that African agency is gaining momentum cannot disguise the fact that Africa has yet to move from rhetoric to implementation in the realm of sustainable development. Continental visions often fail to go beyond declarations of intent, and have only limited influence on governance systems or national structural transformation, and African states remain vulnerable to economic shocks emanating from the global system.

African agency should not be only seen as emanating from government, but also as being exerted by independent civil society organizations and committed ordinary individuals.

Change will require governance systems that are coordinated, transparent, efficient, and inclusive, as well as tools, processes, and means (material, technical, and human) for successful implementation. There is an urgent need for a new governance paradigm in Africa and internationally, dealing with long-term social change.

Notably, African agency should not be only seen as emanating from government, but also as being exerted by independent civil society organizations and committed ordinary individuals. Effective agency needs to be multi-faceted and multi-actor, and depends on the inclusiveness of African governments and their willingness to work with civil society in their strategic engagements with external partners.

Both Agenda 2063 and the SDGs hold the potential for transformation, but implementation will depend on continued advocacy to hold authorities to account and change the dominant discourse, logic and rules of engagement at global, regional, national, and local levels. There is a need for a dynamic new model of African ‘development’.

Time for a new vision

Africa’s economic landscape is changing rapidly, with new regional and local value chains, and integrated regional economic corridors to link countries, minimize the burden of high-cost production and logistics, and boost real incomes and international competitiveness. But Africa continues to face structural challenges, including the need for large investment projects – at a time when Africa remains a net exporter of capital.

Donors and development partners must reflect upon their prior modes of engagement and commit to genuine and equitable relationships with African states. Such partnerships must reflect mutual respect of ideas and accountability, and commit to making space in international forums and multi-lateral arrangements for African people and countries to realize their own visions for progress.

More resources should be channelled to actors engaging closest to communities and people, who can better understand and communicate local needs.

But African leaders and actors must also recognize that with the advent of resources and agency comes responsibility for results and outcomes, notably the need to improve governance. Gaps in accountability, widespread corruption, and lack of successful implementation and sustainability of projects must be addressed.

Africa’s maritime agency cannot be overlooked

Africa’s maritime agency cannot be overlooked Expert comment LJefferson 3 November 2022

Increasing maritime awareness has already delivered impact, but consistency and continental leadership are needed to realize the sector’s full potential.

Africa’s 48,000 kilometres of coastline, shared among 38 coastal states, are resource rich and hold some of the world’s most strategic sea lanes, including the approaches to the Suez Canal, which carries 12 per cent of worldwide trade, and the Gulf of Guinea, a critical route for global energy. But despite the vast potential this represents, piracy and maritime insecurity have dominated the narrative of Africa’s coasts, and further propagated the image of African states as beholden to external intervention.

Yet African agency is established and evolving in the sector, with African littoral states enhancing their capacity to face collective security threats and exercising increasing autonomy in responding to the recent rush of external actors looking for port facilities and military bases. Enhanced continental coordination, consistency and leadership can help Africa’s maritime endowment become a resource that can bring sustainable benefit across the continent.  

Agency beyond piracy: the Gulf of Aden and Western Indian Ocean

Piracy became the dominant frame of reference for the East African maritime space as a result of the crisis off the coast of Somalia, which peaked between 2008 and 2012. In 2008, the UN Security Council (UNSC) took the unprecedented step of authorizing international naval operations in Somali territorial waters, contributing to a gradual reduction in attacks. There have been no successful hijackings reported since 2017.

As the immediate threat of piracy has quietened, broader geopolitical dynamics have come to the fore, notably in a surge by external actors to establish strategic ports and military bases.

But progress has not just been down to international assistance. Somalia is prioritizing increased domestic enforcement capacity – as demonstrated in the establishment of  a new specialized maritime unit and the wider region enhanced collaboration and information sharing through the Djibouti Code of Conduct of 2009, amended in 2017.

South Africa’s recent admission as a new signatory demonstrates its continued relevance. In March 2022, the UNSC authorization lapsed, following pressure from the Somali government. Although it is not yet clear whether Somali efforts will be sufficient to repress piracy in the long term, this reverse was a clear statement of Somalia’s agency at a level unthinkable during the outset of the crisis.

As the immediate threat of piracy has quietened, broader geopolitical dynamics have come to the fore, notably in a surge by external actors to establish strategic ports and military bases. Here too, African states have demonstrated enhanced agency, for better or worse. Consider Djibouti’s unilateral seizure of a container terminal from an Emirati firm, Sudan’s review of Russian and Turkish deals for maritime facilities, Tanzania’s rejection of a Chinese-led port investment, or the Seychelles withdrawing agreement for an Indian naval base.

Such examples point to a growing awareness of the value of maritime resources within African states, alongside a willingness and ability to push back against external imposition – and indeed to innovate in finding solutions beyond infrastructure and ‘hard’ security. In 2018, the Seychelles launched the world’s first sovereign blue bond to fund sustainable marine projects. That other countries are seeking to replicate this model points to the potentially global impact of African leadership on maritime issues.

Regional cooperation or competition in the Gulf of Guinea?

The Gulf of Guinea is likewise resource rich and geographically strategic, and has faced diverse maritime security threats including piracy, smuggling, illegal fishing, oil theft and pollution. Gulf of Guinea states put in place several initiatives to promote security, including the Yaoundé Code of Conduct (YCoC), signed by 25 states in 2013, that led to information-sharing and cooperation on interdiction, investigation and prosecution. But crime in the Gulf of Guinea nonetheless reached an all-time high in 2020, suffering 130 of the 135 maritime kidnappings recorded worldwide, due to the non-binding nature of the YCoC and gaps in capacity and finance.

Despite the clear impact of growing African agency in the maritime space, a long road remains towards the realization of its full potential.

Though external actors have become increasingly engaged, including the EU, US, France, Denmark, and the G7++ Group of Friends of the Gulf of Guinea (FOGG), states within the region, especially those most affected by piracy and armed robbery, have nonetheless demonstrated leadership. Nigeria, Ghana, and Cote D’Ivoire have all developed maritime security strategies; Nigeria launched its Deep Blue Project to secure Nigerian waters; Ghana has strengthened its navy; and Togo has changed its laws and judicial system to allow the arrest and prosecution of ships and persons. Maritime security incidents have consequently reduced in 2022.

Fighting over ‘white gold’: Sesame in Ethiopia and Sudan

Fighting over ‘white gold’: Sesame in Ethiopia and Sudan Expert comment LJefferson 3 April 2023

The supply chain of a seemingly innocuous cash crop – sesame – has intersected with transnational conflict dynamics, exacerbating tensions between Ethiopia and Sudan.

Late 2020 saw the beginning of the devastating war in Tigray and the occupation of a disputed region on the Ethiopia–Sudan border – Al Fashaga – by the Sudanese army. These shocks disrupted settled patterns of land ownership and control in both Ethiopia’s volatile north and Sudan’s borderlands, historically the heart of the sesame and oilseed production that is economically vital to both countries.

These seemingly harmless cash crops are now embedded in local, subnational and national political contestations in both countries. Sesame value chains are being reshaped, with power and profits being used to entrench the grip of political and armed actors who are reinforcing new patterns of land control and driving informal and illicit trade – impacting the coping mechanisms of local communities and threatening to fuel further conflict.

Regional rivalries drive contestation over the Ethiopia supply chain

Internal borders between most of Ethiopia’s regions are marked by boundary disputes, which often degenerate into violent conflict. The most important is between the Tigray and Amhara regions. Since the war began in 2020, the Amhara region has annexed vast areas of western and southern Tigray, which the Amhara region claims were taken from them by Tigray 30 years ago, after the Tigray People’s Liberation Front (TPLF) dominated ethnic coalition came to power.

Conflict has exacerbated a steady decline in formal revenues from sesame exports, dropping over $115 million from 2016 to 2021.

Ethiopia’s exports of spices, oilseeds and pulses brought in over half a billion dollars in 2021, roughly a quarter of the country’s total export revenues and second only to coffee. The sector has been rocked by the war in the north, which accounted for much of Ethiopia’s sesame production, with an estimated 500,000 hectares of sesame fields taken out of cultivation during the 2021 growing season. Conflict has exacerbated a steady decline in formal revenues from sesame exports, dropping over $115 million from 2016 to 2021.

Alongside falling production, the previously integrated value chain has been disrupted and decentralized by political fragmentation and land competition between Amharas and Tigrayans. Before the war, the agricultural sector in Western Tigray/Welkait was dominated by Tigrayan business interests, through the TPLF’s regional endowment fund EFFORT, a business conglomerate including subsidiaries such as Guna Trading House, and Hiwot Agricultural Mechanization.

" class="video-embed-field-lazy">

Two-minute video explainer: Supply chains, land contestation and conflict in the Horn of Africa

The taking of the area by Amhara forces in late 2020 saw the control over agricultural supply chains shift to actors from the Amhara region, amid contestation between regional officials, businessmen and security actors, backed by political elites. Thousands of displaced ethnic Tigrayan inhabitants of the area have been replaced by ethnic Amharas, enticed to settle there by the Amhara regional government’s offer of grants and leases for land which promise better livelihoods. The sesame they farm is now largely exported through informal and illicit channels, with profits used to reinforce de facto regional control.    

But there is also contestation within the Amhara region over the land and sesame supply chain between sub-regional elites from Gojjam, Gondar and indigenous Welkaites. Welkaites, who were marginalized under TPLF rule, believed that by aligning themselves with powerful Amharas they would reclaim land and influence. But this has not been fully realized, with the local administration reliant on Amhara region subsidies, rather than the federal budget. With little support from the federal government, local Welkait officials are strengthening their ties with Eritrea.

The Ethiopian government’s pursuit of peace with Tigray may lead it to turn away from the Amhara region, which could result in a renewed showdown between Amhara and Tigrayan forces.

At the national level, regional contestation over the control over Western Tigray/Welkait feeds into shifting political alliances between the Amhara, Tigrayans and Oromo which threaten the sustainability of the peace agreement struck between the federal government and TPLF in November 2022 – despite efforts by the government to defer the thorny issue.

While the constitutional return of the land to Tigray remains unlikely anytime soon, there is a feeling that Amhara control over Western Tigray/Welkait is no longer certain. The Ethiopian government’s pursuit of peace with Tigray may lead it to turn away from the Amhara region, despite their alliance during and before the war, which could result in a renewed showdown between Amhara and Tigrayan forces.

The prospect of losing territory could also heighten Amhara nationalist claims on Al Fashaga – the loss of which was partly offset by gaining Western Tigray/Welkait – leading to renewed conflagration with Sudan, outside of federal direction. Eritrea’s presence and alliance with Amhara militias remains a concern, given Asmara’s demonstrable ability to inflame tensions.  

Sudan’s securocrats battle over resources to entrench political power

The war in northern Ethiopia was also used opportunistically by the Sudanese Armed Forces (SAF) to take control of the fertile Al Fashaga borderland. This roughly 250 sq km area had been awarded to Sudan when the boundary was initially demarcated by the British in 1903, a ruling that remained contested by Ethiopia. An uneasy truce had seen Ethiopian farmers cultivate the land under nominal Sudanese administration; a settlement that collapsed in 2020 when thousands of predominantly Amhara farmers were evicted.

Local Sudanese farmers have also lost out – with some not compensated for the loss of lands to their own military, with land given to people from other parts of the country, and through lost relationships with Ethiopian farmers, labourers and investors.

The Sudanese military now allegedly controls more than 90 per cent of the disputed areas and security-linked companies and investors have moved into the lucrative sesame sector, re-routing the supply chain, which used to flow largely through Ethiopian markets. These companies are connected to Sudan’s Military Industrial Corporation, a vast conglomerate of business subsidiaries controlled by SAF – which is headed by General Abdel Fattah al-Burhan.

Competition between Sudanese security actors fuels volatile political rivalries, and further entrenches military control of economic resources.

The commander of the paramilitary Rapid Support Forces, General Mohamed Hamdan Dagolo (or Hemedti), also has interests in agriculture, through his family business Al-Junaid. Both sit at the top of Sudan’s Sovereign Council. Hemedti’s competition with Burhan has seen him develop relations with Ethiopia’s prime minister – counter-balanced by recent rapprochement between Abiy and Burhan – as well as senior Amhara leaders, including over business activities.

Moreover, competition between Sudanese security actors fuels volatile political rivalries, and further entrenches military control of economic resources, undermining civilians at a time when pro-democracy forces are seeking to restore a reform-minded government. One of the key challenges for a new civilian government will be to quickly build up a domestic revenue base to compete with the economic heft of the country’s prominent security institutions, which will demand taking on military-controlled holdings in civic sectors such as agriculture, including sesame.

Informal and illicit trade reinforces conflict dynamics

This context has driven the informalization of trade, with cash crops such as sesame increasingly exported outside of formal channels and connected to other illicit cross-border activities between Ethiopia and Sudan. Indications are that sesame production in Western Tigray/Welkait has recovered significantly during the current 2022/23 harvest season. However, rather than contributing much needed currency to soften Ethiopia’s forex crisis, the Amhara elite-controlled supply chain is primarily being used to secure a variety of regional interests.
