Rising tensions between Egypt and Ethiopia over construction of the Grand Ethiopian Renaissance Dam (GERD) have led to speculation that there could be a war over water. When completed, the dam will be the largest in Africa. And it will give Ethiopia control over the Blue Nile River, a major source of Egypt’s water.

Scientists agree that many countries in tropical, subtropical, and arid regions should expect changes to water availability and supply from climate change. The U.S. intelligence community has likewise warned of water-driven challenges not only for countries directly affected by water changes, but indirectly to various U.S. national security interests. Perhaps not surprisingly then, the popular literature has been quite clear about prophesizing wars over water.

A steadily increasing global population, growing food demand, and changing climate necessitate new kinds of thinking in agriculture but also fields like public health and energy, concludes a new book, Hot, Hungry Planet, by former Wilson Center Public Policy Scholar and current Senior Fellow at the National Socio-Environmental Synthesis Center Lisa Palmer.

In 1981, Nobel Laureate Amartya Sen noted that “starvation is the characteristic of some people not having enough food to eat. It is not the characteristic of there being not enough food to eat.” Sen was referring to the idea that hunger is not always related to food supply; even in places where ample food exists, many people do not have regular access to it. Yet, more than three decades later, research into the effects of agriculture on armed conflict is still focused much more on the former than the latter.

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.

Urbanization is changing the face of poverty and marginalization, and the maternal and newborn health field needs to change too, said a panel of experts at the Wilson Center on January 24.

Since becoming an independent nation in 1962, Uganda has struggled with high rates of poverty, regional and international conflict, and both endemic and epidemic disease outbreaks, particularly HIV/AIDS. In recent years, though, it has become a key partner of the United States. The U.S. government provides foreign assistance to improve the lives of Ugandans but also to advance stability in the East Africa region generally, with the bulk of these programs administered by the U.S. Agency for International Development (USAID).
