“Globally, nearly one billion people still lack access to safe water,” said Sasha Koo-Oshima, Senior International Water Advisor for the U.S. Environmental Protection Agency, at a recent Wilson Center event on the potential challenges and opportunities of wastewater treatment. “In emerging developing countries, children lose 443 million school days per year due to diseases related to water, sanitation, and hygiene,” she said.

Intense drought in South Africa’s Western Cape Province has led the world-renowned city of Cape Town to the brink of “Day Zero”—the date at which residents would be forced to collect strictly rationed water supplies from shared distribution taps. Water conservation efforts have so far prevented a massive water shutdown, but the city’s rapid population growth and reliance on surface water dams makes it particularly vulnerable to lower precipitation levels. 

Food has long been used by countries to wage both war and peace, and the post-war era of American food dominance is no exception. Bryan McDonald, a professor at Pennsylvania State University, traces the United States’ “Food For Peace” strategy in his recent book, Food Power: The Rise and Fall of the Postwar American Food System, arguing that “food was central to national security” during this period.

“Gender equality and women’s empowerment [need to be] at the center of the fight against extreme poverty, hunger, and malnutrition, and also in any efforts to build sustainable peace,” said Ilaria Sisto at a recent CSIS event on the critical role of women and girls in ensuring food and nutrition in times of conflict.

Starting in 2014, the number of migrants from Central America’s Northern Triangle—Guatemala, El Salvador, and Honduras—surged, with border apprehensions increasing fivefold from 2010-2015. While apprehensions have declined from their peak, emigration from these countries has not necessarily slowed, and the conditions the migrants are seeking to escape have not changed. Experts blame the region’s widespread criminal violence for spurring migration. But the Northern Triangle countries also share similar ecology, staple crops, and vulnerability to climate events. While environmental and natural resource factors are just part of the complex picture, understanding how they intersect with other migration drivers is key to creating and implementing effective policy responses.

According to a 2015 Georgetown University report on women and climate change, “the impacts of climate change – droughts, floods, extreme weather, increased incidence of disease, and growing food and water insecurity – disproportionately affect the world’s 1.3 billion poor, the majority of whom are women.”
