Beginning with the end of the Cold War, a relatively small but growing number of scholars began to investigate the connections between environmental change, conflict, peace, and changing notions of security. The recognition of these linkages wasn’t new, but as the heavy weight of superpower confrontation lifted and new foreign policy dynamics unfolded across the globe, an expanded range of research questions and tools emerged.

The Society of Environmental Journalists’ annual look-ahead to environment and energy news in 2020 drew a crowd of some 300 (with more than 200 watching the live webcast) at National Geographic Society headquarters in Washington, D.C., Jan. 24.

And the overwhelming topic of discussion — climate change.

The Western Sahel region—a cluster of arid, low-income countries stretching from Senegal, on Africa’s Atlantic coast, inland to Mauritania, Burkina Faso, Mali, Niger, and Chad—is home to the world’s most youthful populations. According to current UN Population Division estimates, about 57 percent of this six-country region’s population is 19 years old or younger. As security conditions deteriorate across the rural Sahel, governments in Europe and North Africa are taking notice of these countries’ demographic status—and for good reasons. Sustained population youthfulness (often called a “youth bulge”) contributes to low levels of educational attainment, joblessness and social immobility, and ultimately to rapid population growth, which tends to drive declines in per-capita availability of freshwater and other critical natural resources: factors that are associated with the risk of persistent violent conflict and represent powerful push factors for migration.

The Amazon endured the most intense fire season in almost a decade in August 2019. On August 19, smoke from the faraway fires blackened the skies over Sao Paulo. By the next day, the hashtag “#PrayforAmazonia” was sweeping across Twitter. The social media outcry brought world attention to the already dire scientific warnings, and world leaders offered aid and pressured Brazilian President Jair Bolsonaro to take action.

“This is a unique moment—a crisis that has demanded action for decades and is now getting the attention it deserves,” said U.S. Representative Lauren Underwood (D-IL-14) at a recent event on maternal health and disparities hosted at George Washington University’s Milken Institute School of Public Health. The United States has the highest maternal mortality rate among high-income countries and for every maternal death, there are 70 “near-misses.” It is important to take a “life-course” approach to address this issue from a policy perspective, said Underwood.
