In a June 12 speech to governments and NGOs at UNHCR’s annual consultations on refugee resettlement in Geneva, UN High Commissioner for Refugees Filippo Grandi made a passionate plea for additional resettlement pledges from participating nations. He will likely be disappointed.

More than 60 percent of the world’s refugees and 80 percent of internally displaced persons (IDPs) now live in urban areas. In contrast to traditional refugee camps, which have mainly been in rural areas, cities and other urban settings can offer refugees greater economic opportunities, a degree of anonymity, and better access to services—at least in theory, said Mary Nell Wegner, executive director of the Maternal Health Task Force, at the Wilson Center on May 31. However, in practice, the urban advantage may be a myth, as local systems, already strained by growing populations, are not well equipped to handle a large influx of people with complex needs.

U.S. prosperity and national security depend directly on the prosperity and stability of our partner countries and competing countries around the world. Today, water-driven stresses are, with increasing frequency, undermining economic productivity, weakening governance systems, and fraying social cohesion. Water scarcity has created a context of human and societal need wherein water stress has undermined the vitality of rural livelihoods, driven broad migratory movements, become a weapon of war, contributed to the growth of insurgencies and terrorist networks, and given rise to increased demand for U.S. development, humanitarian, and military assistance.

“There’s a long list of crises that can have a natural resource base,” said Anne C. Richard, former assistant secretary of state for population, refugees, and migration, at a Stimson Center panel on June 13, 2017, on the impacts of climate change on human security and mobility. The panelists included Kelly McFarland of Georgetown’s Institute for the Study of Diplomacy (ISD), Rod Schoonover of the National Intelligence Council, and Sally Yozell, director of Stimson’s Environmental Security Program.

In 2013, a boat capsized 61 miles from the Italian island of Lampedusa killing 268 refugees including 60 children. It was another horrific example of the risks taken by so many families fleeing violence in the Middle East and Africa. But recently released tapes of conversations with coast guard authorities reveal a deeper tragedy.

Recent rises in temperature and typhoon frequency and intensity have resulted in more internal migration in the Philippines, according to an article by Pratikshya Bohra-Mishra et al. in Population and Environment. The authors conclude that temperature change and natural disasters, such as typhoons, can have a significant effect on short-distance, sub-national migration because they reduce rice yields, which is used as a proxy for agricultural productivity.
