Agriculture
is the key source — and in many cases, the only source — of income for
many living in the developing world. When drought hits, it has the
potential to take away everything and unravel the threads that stitch
together society.
New findings
published Monday in the Proceedings of the National Academies of
Science are part of a burgeoning body of literature showing how climate
change can lead to conflict. It shows that drought exacerbates existing
conflicts in some of the poorest countries and the farmers who are most
dependent on a stable climate for their livelihoods. The findings
highlight why climate change is intimately tied with development, national security and morality.

The impact of climate change on conflict
is an area of intense research and interest. With carbon pollution
expected to continue altering the climate, knowing its impact on
conflict would be a major asset to researchers and policymakers looking
to make the world a more peaceful place.
A number of previous studies have studied climate and conflict. Among the more tantalizing findings was that drought in Syria helped spark the subsequent civil war that has torn the country asunder. Rather than taking a high-level view
as a number of previous studies have or focusing on a specific
conflict, the new research zooms in to the subnational level in Africa
and Asia and looks at drought during the growing season.
The
results show that drought during growing seasons can prolong or
intensify existing conflicts, though it’s not as likely to spark new
ones.
“This effect is most pronounced in countries that are not very developed economically,” said Nina von Uexkull,
a peace and conflict researcher at Uppsala University in Sweden who led
the new study. “It’s also pronounced in groups excluded from political
power.”Von Uexkull’s findings also show that groups heavily reliant on agriculture are most at-risk. In essence, drought preys on already weak groups and institutions, eating away at what little stability they have. The results specifically show that drought increases the odds of conflict by about 5 percent.
That might sound small, but Marshall Burke, an economist at Stanford University, said the number belies how big that risk might be even in communities where the linkage seems relatively weak.
“This could represent like a 50 percent or greater increase in the probability of conflict,” Burke said in an email. “That is a HUGE effect.”
Research and reality have regularly pointed to the fact the world’s poorest will be hit the hardest by climate change. The findings are the latest to underscore how climate change is as much a development and justice issue as it is an environmental one.

The findings could add fuel to the discussion at United Nations climate talks next month in Morocco, which will focus on the thorny topic of loss-and-damage or how developed countries will help developing countries recover from climate and weather disasters. With climate change expected to make dry places drier and increase the incidence of drought in some locations, the findings could make conflict a bigger part of the loss-and-damage discussion.
For all the bad news in the study, there’s also a sliver of good news. Groups that are more stable and have access to diverse sources of income aren’t as prone to conflict following drought. Von Uexkull said the findings are a compelling case for targeting international development in a way that also helps people adapt to changes in the climate.
“It’s extremely important from an climate adaptation point of view to understand these circumstances,” she said. “It will help design policies in areas where this relationship occurs and where in the future climate change will make drought worse.”
