This year marks the 30th anniversary of the fall of the Berlin Wall. The wall, which stood between 1961 to 1989, came to symbolize the ‘Iron Curtain’ – the ideological split between East and West – that existed across Europe and between the two superpowers, the US and the Soviet Union, and their allies, during the Cold War. How significant was the Berlin Wall during the Cold War – was it more important physically or psychologically?

The Berlin Wall was important physically, as well as psychologically, because Berlin was the only city that was divided physically by the Cold War between the Soviet Union and its allies in the Eastern Bloc and the West.

Given the disparity that quickly emerged between the two sides in economic wealth, freedom of expression and so on, the fear was that, without that wall, there would've been a unification of Berlin in a way that the Soviet side would have lost.

But it was also very important psychologically because it became the symbol of the division between two ideologies that saw each other as inimical to each other.

That meant that if you wanted to visualize the Cold War, and the separation between the capitalist, democratic system of the West and the communist, command-and-control system of the East, Berlin offered a place where you could physically walk from one world, through a checkpoint, into the other. The whole Cold War could be reduced to this one nexus point.

Because of its psychological as well as its physical significance, the fall of the Berlin Wall quickly became the symbol of the collapse of the communist ideology it had shielded.

Since the fall of the Berlin Wall, European countries have reportedly built over 1,000 kilometres of walls – the equivalent of more than six times the total length of the Berlin Wall – along their borders.

Why has Europe been building more walls and how effective have they been? Have they been used more as symbols to appeal to political bases, and if so, has it worked with voters?

The walls that have been built in Europe recently have been for a very specific reason. This was the huge influx of migrants and refugees to Europe in 2015, through what was called the ‘eastern Mediterranean’ or ‘western Balkan route’, from Turkey to Greece and on through the Balkans, Serbia and Hungary to northern Europe – in what was Europe's biggest migrant and refugee crisis since the Second World War.

What’s interesting is that for Viktor Orbán and the Hungarian government, which was on the frontline of the flow of migrants and refugees, building a wall was a way of reasserting its sovereignty. 

Like many other countries along the ‘migrant route’, they resented that the rules under which people could migrate into Europe were flouted by northern European governments which were willing to accept large numbers of migrants and refugees.

By accepting them, they kept attracting more, and so Orbán was worried that, at some point, Germany might say ‘We can’t take anymore’ and they’d be left in Hungary.

It’s important to remember that the communist states of central and eastern Europe were kept in aspic by the Soviet Union – they existed in a hermetically sealed environment without immigration. As a result, they didn’t experience the rise of multicultural societies of the sort that emerged in Britain, Belgium, France and Germany, where immigration persisted throughout the Cold War period.

The countries of central and eastern Europe were delighted that the Berlin Wall collapsed because it allowed them to unify with western Europe. They had been vassal states of the Soviet Union during the Cold War, and by joining the EU, they re-discovered personal freedom and re-gained national sovereignty. They thought they had become masters of their own future again.

But they suddenly found they were on the frontline of a new movement of people that wanted to get into the same world that they’d entered some 15 years earlier. And, as hundreds of thousands of migrants and refugees began arriving, they suddenly realised they were in a union that did not respect their sovereignty.

So, for them, putting up walls was a sovereign act against a European Union that didn’t seem to take their sovereignty seriously.

Has it worked? Definitely. The flow of migrants has been reduced drastically. This is partly because the EU paid Turkey to hold back the over three million migrants based there. But the walls also acted as a physical and psychological deterrent. 

It also worked politically. It allowed Viktor Orbán and other European parties that took the sovereigntist line to strengthen their appeal to voters – voters like to know that governments can do certain things like protecting them and their borders.

What is hypocritical, however, is that many of the governments in western Europe which criticized the Hungarian government for building its wall have actually been rather grateful that they did so as it slowed down the flow of migrants to their countries.

Then there’s the additional hypocrisy of the EU criticizing Donald Trump for building his wall with Mexico when Europeans are benefitting from theirs in Hungary.

Two years before the fall of the Berlin Wall, former US president Ronald Reagan challenged Soviet leader Mikhail Gorbachev to ‘tear down this wall’ declaring ‘across Europe this wall will fall. For it cannot withstand [freedom].’

32 years later, building a wall along the US–Mexico border has become a cornerstone of the current US administration under Donald Trump who has pledged to build a ‘big beautiful wall’. How does this reflect the political evolution of the US and what effect does that have across the rest of the world?

President Reagan talked about tearing down the Berlin Wall as a symbol of the Cold War. He knew that the fall of the wall would undermine the Soviet Union. 

President Trump is way beyond the Cold War. Building a new wall is his response to the growing sense of economic dislocation that segments of America, like Britain and other parts of Europe and the developed world, have experienced on the back of the rise of globalization, which was partly the result of the end of the Cold War but also the rise of China.

The spread of globalization, the declining earning power of many workers in the West, advances in technology which have taken away many high-earning jobs, the eight years of austerity after the global financial crisis – these are all factors driving Trump’s thinking. 

Have inflows of Mexican immigrants or immigrants through the Mexico border been the principal driver of economic insecurity?  No.  What you’ve got is Trump promising to build a wall as a symbol of his administration’s determination to protect Americans.

So I’d say the US–Mexico wall is another symbolic – or psychological – wall. Trump’s wall is supposedly about stopping illegal immigration but there are still plenty of ways to come through the border posts. It’s principally an exercise in political theatre.

From the Great Wall of China to Hadrian’s Wall, walls and fences of all sorts have been used throughout history for defence and security, but not all of them have been physical.

So-called ‘maritime walls’, as well as ‘virtual walls’, are also increasingly being enforced which, today, includes border forces patrolling seas and oceans, such as in the Mediterranean Sea or off the coasts of Australia, and border control systems controlling the movement of people. Politically how do these types of barriers compare to physical ones?

You could argue that the Mediterranean Sea, and the European border forces operating within it, still act as a physical wall because they constitute a physical obstacle to migrants being able to move from the South across the Mediterranean Sea into Europe. 

So I don’t see this maritime wall being much different to the physical walls that have been built to try to stop migrants – just like any other border patrol, the Italian navy is preventing NGO vessels carrying migrants, who have been stranded at sea from docking at Italian ports. 

In this sense, you could argue that the Mediterranean Sea is a larger version of the Rio Grande between the US and Mexico which also incorporates physical barriers along its shores.

I think the more interesting walls that are being built today are virtual walls such as regulatory walls to trade, or with the internet, new barriers are being built to digital communication which affect your capacity to access information. 

In the end, all these walls are manifestations of national sovereignty through which a government demonstrates it can ‘protect’ its citizens – whether they are successful in this objective or not.

The border between Ireland and Northern Ireland, and the presence of enforcement mechanisms along the border, has become a key issue in the Brexit negotiations. How much of the debate over this is about the symbolism of the border against its economic implications?

The Irish border carries great symbolic importance because it reflects the reality of the separation of two sovereign states.

On the island of Ireland, the British and Irish governments have wanted to minimize this reality to the greatest extent possible. They even went as far as removing all types of barriers as part of the Good Friday Agreement.

This is the same sort of fiction the European Union created when it removed any physical manifestations of the existence of borders between those member states in its Schengen agreement on borderless travel.

By removing physical manifestations of the border, the UK was able to reduce some of the popular support for Irish unification as well as support for the IRA’s campaign of violence and terrorism to try to force the same outcome. 

Brexit has thrown a huge spanner into this arrangement. If Brexit is going to mean the entire UK not being in the EU’s customs union then some sort of border would need to be reinstated.

The British government proposed to do all the checks behind the border somewhere. The EU’s view was, ‘Well, that’s nice for you to say, but this border will become the EU’s only land border with the UK, and you cannot guarantee that people won’t be able to smuggle things through.’

On the other hand, recreating a border of some sort, whether physical or not, would reignite the differentiation between the two nations – running counter to the spirit of the Good Friday Agreement.

The only solution available to Prime Minister Boris Johnson has been to put the border down the Irish Sea.  While this means that Northern Ireland will no longer be an obstacle to the UK signing new, post-Brexit, free trade agreements with other countries, it has betrayed the Conservative Party’s unionist allies, for whom it’s essential that the UK’s borders include and not exclude them. 

By the end of the Cold War there were just 15 walls and fences along borders around the world, but today, there are at least 70. How effective, do you think, building barriers are as a political and military strategy to defence and security issues given their financial – and human – cost?

Physical barriers can be an effective form of protection – or imprisonment. 

The separation wall between Israel and the Palestinian territories has reduced the level of terrorist violence being perpetrated in Israel, but the cost has been the impoverishment of many Palestinians, and is another nail in the coffin of a two-state solution.

Yet many Israelis are saying that, maybe, being entirely separate is the best way to achieve peace between the two sides.

However, the walls around the Gaza Strip have not prevented, for various reasons, the Hamas government from developing rockets and firing them into Israel.   

You could argue that the border between China and North Korea, which is severely patrolled, has been a tool of continued political control protecting the Kim Jong-un regime from collapse – as has its virtual border preventing internet penetration.

Similarly, the virtual border the Chinese government has created around its own internet, the ‘great firewall’, has been very effective both economically – allowing Chinese internet platforms to develop without the threat of competition – and also as a form of political control that helps the Chinese Communist Party retain its monopoly on power. 

So walls in all of their shapes and forms can work. They are like sanctions – sanctions are easy to impose but difficult to remove. Walls are easy to build but they’re difficult to break down. 

But my view would be that they still only work temporarily. In the end, walls serve their particular purpose for a particular period, like the Berlin Wall, they end up outliving their purpose.

You have to be alive to the fact that, whether that purpose was a good or bad purpose, there will be a moment when walls end up protecting the interests of an ever-narrower number of people inside the wall, while they cease serving, if they ever did, the interests of the growing number on both sides. 

It’s ironic that the fall of the Berlin Wall in November 1989 was not the main marker of the end of the Cold War. It began earlier that year, with the intensification of people protesting in Poland, Hungary and Czechoslovakia.

Once Hungarian troops dismantled the fence separating them from Austria in May 1989, thousands of Hungarian citizens simply walked out of their country, because by then, the wall between the East and West only existed in their minds.

Then, once East Germans also realized that Mikhail Gorbachev and the Soviet regime had lost its willingness to defend the Berlin Wall, it collapsed. 

So it is interesting that we’re marking the end of the Cold War with this anniversary of the fall of the Berlin Wall, which of course, did divide two halves of one country, making its fall all the more poignant and powerful. But the end of the Cold War really began with the fall of the invisible wall in people’s minds.

• Political, economic, sociological and technological factors are poised to challenge EU and US ideological positions on internet governance, which will make it difficult to find consensus and common ground in the years to come.
• The EU and US share core values and perspectives relating to internet governance, such as openness, freedom and interoperability, as well as a human rights framework for cybersecurity. There have been many examples of successful multi-stakeholder cooperation between the EU and US, including the Internet Assigned Numbers Authority (IANA) transition and the European Dialogue on Internet Governance (EuroDIG).
• There are also subtle differences between the EU and US, and each has different reasons to support multi-stakeholderism. Cases that highlight growing tensions in EU–US coordination on internet governance include the controversies surrounding the EU General Data Protection Regulation (GDPR), the WHOIS system that governs domain name registration data, and the board of the Internet Corporation for Assigned Names and Numbers (ICANN), which undermined an independent cybersecurity review.
• Internet governance is becoming more complex, with a multiplicity of actors and no obvious authority for important emerging issues. Additionally, the rise of China and its authoritarian vision for the future of the internet is a threat to the current internet governance institutions that have been shaped by and reflect Western values.
• To bridge ideological gaps the EU and US should build capacity between likeminded stakeholders, create a taskforce on effective multi-stakeholder internet governance, and work through non-governmental stakeholders to improve participation.

Labour leadership candidate, Lisa Nandy, reflects on the party's foreign policy priorities and makes the case for a foreign policy underpinned by internationalism.

In recent years, the Labour party has struggled to reach cross-party consensus on its foreign policy agenda. While the current leadership election offers the party an opportunity to debate and redefine its position on issues such as immigration, security and Brexit, the extent to which Labour can reconcile its factionalism remains unclear. As Labour undergoes a process of reflection, what kind of foreign policy agenda should the party rally behind that will also appeal to voters outside of its traditional base?

Can the Labour party be unified on its approach to international issues? Is an internationalist foreign policy an attractive choice for voters? And as Brexit tensions persist, what might the party's framework be to ensure new trade deals and partnerships align with fundamental Labour priorities such as workers' rights?

• Meeting future global food security requirements is not just about quantity; it is also about meeting growing needs in a way that safeguards human as well as planetary health. But national priorities and policies often remain out of sync with aspirations for more sustainable and healthy food systems.
• International trade and trade policies play an ambiguous role in the current food system. With 80 per cent of the world’s population depending on imports to meet at least part of their food and nutritional requirements, trade has a unique function in offsetting imbalances between supply and demand. However, in the absence of effective regulatory frameworks or pricing frameworks that internalize environmental, social or health costs, trade can exacerbate and globalize challenges associated with food production and land use trends such as deforestation, land degradation, greenhouse gas emissions, biodiversity loss and the shift to unhealthy diets.
• Over the last two decades, trade in agricultural products (excluding intra-EU flows) has more than tripled in value, to reach $1.33 trillion. The geography of global food trade flows has also shifted, primarily towards South–South trade, which now accounts for roughly a quarter of total agricultural trade flows. The nature of global trade has changed drastically, with traditional exports such as wheat and coffee growing slowly at around 2 per cent per year, while products such as palm oil, fruit juice, soft drinks and other processed products have grown at 8 per cent or more annually.
• This overall increase in trade in agricultural products raises questions about the growing utilization of resources, such as water or soil nutrients, that are embedded in those products through production and processing. Trade itself also causes negative environmental impacts, starting with greenhouse gas emissions associated with transport and storage. If the environmental cost associated with production and trade is not reflected in the final price of goods, trade may accelerate the depletion of resources or their unsustainable use.
• It is critical to ensure that trade policy options pursued by producing and consuming countries alike will support a transition to more sustainable and healthier food and land use systems. The first step in addressing trade-related food systems challenges must involve rebuilding trust among policy actors. There is a need for new spaces for informal dialogue among actors, and ‘soft’ governance mechanisms that can help rebuild consensus on the best ways forward. Meeting these challenges also requires an appreciation of the complex interactions between sectoral policies (e.g. on water, land, food, etc.) and their multiple interfaces with trade policies. 
• Conditioning the use of subsidies on their sustainability and/or health impacts encourages the delivery of essential public goods in ways that are consistent with sustainability and health goals. A first step therefore is the removal of perverse incentives (e.g. subsidies encouraging the overuse of fertilizers or pesticides or the overproduction of certain commodities, as well as certain biofuels subsidies) and replacing them with market-correcting subsidies.
• Trade facilitation measures for fruits and vegetables that are aimed at easing transit at the border, by cutting unnecessary bureaucracy and reducing waiting times, can improve their availability, reduce costs and improve food quality and safety for consumers. Similarly, measures aimed at improving sustainable cold storage and upgrading value chains can support better diets and consumption by increasing the availability of fresh produce on markets, especially in developing countries.
• A global food stamps programme developed through the G20 and facilitated by the UN’s food agencies could address purchasing power imbalances and tackle malnutrition in developing countries. If carefully designed, such ‘safety net’ schemes can not only contribute to improving calorific intakes but also help deliver more balanced and healthier diets. Careful attention must be given to how such a scheme would work in practice, building on experience to date with similar initiatives.
• Integrating the notion of sustainable food and inputs trade in the post-2020 global biodiversity framework can help to deliver more sustainable and healthier food and land use systems. This could be achieved by likeminded countries introducing a set of goals or targets aimed at mitigating the role of trade in placing indirect pressure on biodiversity, and to encourage trade in biodiversity-based products including natural ingredients produced ethically and following sustainability principles and criteria.
• An SDG-oriented agenda for agricultural trade is needed. It could be formed by countries seeking to remove perverse incentives, guaranteeing a safe harbour for market-correcting measures, clarifying existing rules and establishing plurilateral negotiations among subsets of the WTO membership, or sectoral approaches, to address specific challenges.
• Greenhouse gas emissions resulting from trade need to be addressed. Governments could seek to achieve this through ensuring the carbon neutrality of existing and new trade deals, either by connecting carbon markets among contracting parties or by developing joint initiatives to tax international maritime and air transport emissions.

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 stability

Shortages 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 cycle

To 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.

Finance plays a key role in enabling climate change mitigation and adaptation. It is also a contested issue in the UN climate negotiations. The fourth event in the Chatham House COP26 Diplomatic Briefing Series will explore the politics of climate finance in the context of the COP, and provide a comprehensive update of the main climate finance-related negotiation items and processes. The topic is particularly timely given that the UK Government has made climate finance one of its top thematic priorities for COP26 and that 2020 constitutes the deadline for developed countries to mobilise USD 100 billion per year to support climate action in developing countries.
