Where violent conflict displaces people and disrupts societies, maternal and child health suffers, and such instability is widespread today. According to the UN Refugee Agency, there are 65.3 million forcibly displaced people, 21.3 million refugees, and 10 million stateless people over the world.

As Syria has collapsed, spasming into civil war over the last five years, the effects have rippled far beyond its borders. Most notably, a surge of refugees added to already swelling ranks of people fleeing instability in Afghanistan, Iraq, Pakistan, and sub-Saharan Africa, leading to the highest number of displaced people since the Second World War. At the same time, scientists have noted record-breaking temperatures, a melting Arctic, extreme droughts, and other signs of climate change. For some, an obvious question is: what does one have to do with the other?

Record levels of displacement and accelerating climate change have prompted many to wonder if the world is headed toward a more violent future. The nexus of climate change, migration, and conflict is posing fundamental challenges to societies. But not always in the ways you might think. In a new report prepared for the U.S. Agency of International Development, Lauren Herzer Risi and I present a small guide to this controversial and consequential nexus of global trends.
