That future wars will be fought over water, rather than oil, has become something of a truism, particularly with regard to the Middle East. It’s also one that most water experts have refuted time and time and time again. But while this preference for cooperation over conflict may (and emphasis on may) remain true of interstate disputes, this blanket aversion to the ‘water wars’ narrative fails to account for the rash of other water-related hostilities that are erupting across many of the world’s drylands. As neither full-on warfare nor issues that necessarily resonate beyond specific, sometimes isolated areas, these ‘grey zone’ clashes don’t seem to be fully registering in the broader discussion of water conflicts. In failing to adequately account for the volume of localized violence, the world is probably chronically underestimating the extent to which water insecurity is already contributing to conflict.

The last decade was the warmest on record, with 2020 tied with 2016 for the all-time high average annual global temperature. This 10-year period also saw armed conflicts at severity levels not seen since the Cold War era. Could there be a causal link between these trends?

To the frustration of policymakers and laymen alike, empirical research has been unable to provide a simple and coherent answer to this question. Instead, studies of climate-conflict connections have for a long time continued to produce diverging findings and – occasionally – inspired heated debates. So, where do we stand?

In a review article introducing a new special issue of the Journal of Peace Research (JPR) on the security implications of climate change, we assess the nature and extent of scientific progress in climate-conflict research over the past decade. As yardsticks for measuring progress, we identify seven key research priorities frequently advocated in earlier reviews of the quantitative literature. 

Early predictions about COVID-19’s impacts on Africa suggested that the continent would be a disaster zone marked by weak medical systems collapsing under strain and undemocratic states failing to provide social services to destitute populations. These predictions did not come to pass. Instead, many countries across the continent stepped up early on to join the world in curtailing the spread of COVID-19. The second order effects of the virus have been significant, however. Despite the low numbers of infections and deaths, lockdowns and the decline of a large percentage of informal trade and commerce in Sub-Saharan Africa have sent the region’s economy into recession, with increased inflation rates, widespread unemployment, and increased food insecurity. It’s within this context that collaboration (internationally and within the continent, between governments, the private sector, and local communities) to protect the environment—and by extension enhance livelihoods, promote sustainable development, and achieve enduring peace—has taken new forms.

“One hundred thirty-seven women are killed by a family member every day,” said Beth Schlachter, Executive Director of Family Planning 2020. “That’s a staggering statistic.” She spoke at a recent Wilson Center event about gender-based violence (GBV) in conflict and humanitarian settings in partnership with CARE, the International Rescue Committee (IRC), Save the Children, and the Women’s Refugee Commission. The event was a part of a Wilson Center series recognizing the United Nation’s “16 Days of Activism Against Gender-Based Violence” and commemorated our friend and colleague, Jennifer Schlecht.

For most of 2020, news, politics, policy, and research in the United States and abroad were dominated by the challenges posed by COVID-19, a rapidly unfolding global pandemic unprecedented in scale and cost. For much of the world, however, COVID-19 in fact competed with many other highly destructive events including a cascade of environmental disasters. Swarms of locusts pushed much of the Horn of Africa into or close to famine; 30 severe storms including Hurricanes Iota and Eta battered the Atlantic coasts; some 4 million acres of forest burned to the ground in California, doubling the previous high reached in 2018; typhoons ravaged the Philippines; floods overwhelmed parts of Indonesia; and many regions around the world experienced devastating heat waves. In addition to disaster patterns, the trends in violent state conflict were equally alarming, reaching their highest level since the end of World War II, according to a 2020 report on conflict trends from PRIO. In the most violent conflicts, in Syria and Yemen, the impacts of war have been amplified and complicated by the impacts of drought and years of environmental mismanagement.

A new Global Fragility Strategy, released late last year by the U.S. Department of State, signals a growing awareness of the role that environmental issues play in fragility, conflict, and peace. According to the State Department’s Office of Foreign Assistance, in the last five years alone, “the U.S. government has spent $30 billion in 15 of the most fragile countries in the world.” These “large-scale U.S. stabilization efforts after 9/11 have cost billions of dollars but failed to produce intended results,” writes Devex’s Teresa Welsh. As a result, Congress passed into law in 2019 the Global Fragility Act, legislation that directed the Department of State to lead the development of a new 10-year Global Fragility Strategy that sets out a new U.S approach to conflict prevention and stabilization in fragile contexts.

For years, analysts have disputed the extent of climate change’s role in conflict. But the nature of climate risks can stifle those looking to define them.

The Syrian civil war has raged for almost a decade now, and in the climate security community it can feel as if we’ve spent at least that long arguing about its causes. For every claim about the impact of extreme drought in the lead up to 2011, there’s been blowback, with some scholars arguing that the climate angle has been exaggerated at the expense of other causes of the conflict. And for every argument about rural-to-urban migration, there have been suggestions that its impact in precipitating protests has been overstated. Amid some overly forceful media assertion about the significance of climate change—and valid fears that invoking the environment might be seen as absolving guilty parties, despite efforts to highlight the regime’s ultimate culpability—climate security analysts have struggled to fully pinpoint climate’s precise contribution to the conflict. Cue uncertainty, controversy, and sometimes fierce academic polemics.
