Contrary to popular belief, Lake Chad is not shrinking, according to Shoring up Stability: Addressing Climate and Fragility Risks in the Lake Chad Region, a new report from adelphi. This finding has profound implications for how the governments of countries bordering Lake Chad (Nigeria, Niger, Chad, and Cameroon) as well as the international community should address the conflict trap in which the people of the region are caught. “Supporting the people of the basin,” write the authors, “is not a function of saving Lake Chad from desiccation.” 

In April’s top post, Sarah Glaser and Cullen Hendrix find that a mostly domestic armed conflict involving Joseph Kony and the Lord’s Resistance Army increased competition over Nile perch among fisherfolk, which created tensions between Kenya and Uganda.

One year after the Sichuan earthquake, while visiting villages near Wenchuan, I asked local officials planning reconstruction about their plans for wastewater treatment. As an agricultural engineering professor, I was not surprised to learn that they had no plans. It was not that a wastewater treatment system was too expensive, they worried that it would be too big.

The ongoing crisis at our southern border is exacerbating another, less visible, one—the crisis in elder and childcare in the United States. With baby boomers aging and more parents of young children working outside the home, our country’s need for non-familial caregivers is skyrocketing. Carework is growing five times faster than any other sector in our economy; in fact, it is set to become the largest paid occupation in the U.S. by next year. While US citizens are not keen to take these jobs, migrants, especially women, are. But the current bottleneck—not just at the border but throughout our immigration system—is slowing down the flow of these vital workers.

In parts of the tropics, exposure to extreme temperature or rainfall in early life is associated with fewer years of schooling in later childhood. This finding comes from my new article in the Proceedings of the National Academy of Sciences, with coauthor Clark Gray. As climate change leads to increasingly severe heat waves, floods, droughts, and hurricanes, it is important to understand how extreme weather impacts kids’ education in different parts of the world. This will help decisionmakers develop solutions to keep children in school in a world of increasing climate variability.

China’s food security is rooted in its soil.  Sadly, more than 40 percent of China’s soil is degraded from overuse, erosion, and pollution. The government’s 2014 soil survey revealed that 19 percent of China’s farmland was contaminated by metals such as lead, cadmium, and arsenic as well as organic and inorganic chemical pollutants. As part of its growing war on pollution, China’s central government enacted a new soil pollution law on January 1, 2019, to clean up contaminated sites. However, this new law targets just one of the many critical soil quality issues that reduce agricultural yield but does not address the problem of compacted soil.

“African countries are not in the middle of one transition, they are in the midst of several transitions,” said Parfait Eloundou-Enyegue, Professor and Chair of the Department of Development Sociology at Cornell University, at a recent Wilson Center event on demographic trends on the continent, and investing in youth to ensure economic prosperity. “All of these transitions are an opportunity for prosperity, an opportunity for growth, an opportunity to build human capital,” said Eloundou-Enyegue. However, demographic, cultural, political, and economic changes can also exacerbate existing inequalities between and within countries. The challenge is not only to build prosperity, but to do it for all, said Eloundou-Enyegue.

As Arctic ice melts, we can physically see glaciers retreating. But what we can’t yet see is the exact effect climate change will have on the environment, humans, economies, and national security. Less ice for longer periods each year will likely bring opportunities and related challenges as Arctic and non-Arctic states jockey for position.
