“What’s become clear to me on population is that it’s really a local issue,” said Andrew Revkin in an interview at the Wilson Center. “You get the impression, ‘Oh didn’t we solve that problem?’” And to some extent, demographic shifts around the world are largely heading in the direction people anticipated, with a leveling off mid-century. But “no one really knows what happens then,” he said. “All it takes is a tiny diversion of fertility rates and things could really grow or shrink.”

In 2008 and 2010, the price of many basic food stuffs soared, sparking a series of riots and food crises around the world. People in the poorest countries – those living with the smallest margins – were most affected, while the economies of developed nations were able to absorb the price changes. According to Notre Dame’s Global Adaptation Index, how climate change will impact different countries depends not only on their vulnerability to physical changes, but also their ability to absorb these impacts. [Video Below]

When journalist Alan Weisman proposed a new book on the challenges posed by human population growth, his editor said, “That one’s a live wire; don’t touch it.”

The past three years – and more pointedly the past 12 months – have laid witness to monumental, if not heartbreaking, incidents of gender-based violence.

The Environment, Conflict, and Cooperation team talked to Eileen Hofstetter from the Swiss Agency for Development and Cooperation. She is co-author of the Inventory of Shared Water Resources in Western Asia released at this year’s World Water Week in Stockholm.

Population aging and decline are frequently described as a threat to countries’ economic development and social stability. Evocative language, such as “demographic winter” and “graying of the great powers,” portrays the serious consequences that many observers envision as fertility and growth rates decline and the elderly comprise a greater percentage of the population. These concerns reach around the globe, including in Africa, which has the lowest percentage of elderly among the world’s major regions.

Since 2008 – a year in which rapid increases in the global prices for major grains helped to trigger outbreaks of civil unrest in more than 40 countries – scholars and policymakers have paid increased attention to the potential influence of global food prices on social and political instability. Since that time, spiking prices have periodically sparked public protests and governments have struggled to respond.
