In 2007, the world crossed a threshold:  for the first time in human history, the majority of people lived in urban areas. Today, Africa and Asia are the only remaining continents where the rural population outnumbers urban, but they are urbanizing at unprecedented rates. This rapid growth is a double-edged sword. While urbanization spurs economic opportunity and often increases access to infrastructure, it is also widening disparities in health and development, according to a new data sheet by the Population Reference Bureau.

The landscape of the northeastern Indian state of Meghalaya is rapidly changing. What was once a predominately agricultural economy has shifted to coal mining with significant consequences for people and the environment. “Once you extract coal from the land, it’s really hard to go back to an agricultural economy,” says ECSP’s Sean Peoples in an interview with Wilson Center NOW, about the Global Choke Point film, Broken Landscape.

A new article from the Wilson Center’s own Roger-Mark De Souza explores how population trends can bolster community resilience in the face of climate change and other security threats. De Souza argues that demographic trends such as age structure help determine how well a population is able to respond to and bounce back from shocks, especially environmental ones like drought and famine.

At the launch of A New Climate for Peace, a new report on climate-fragility risks produced for the G7 by a consortium of international partners including the Wilson Center, USAID Deputy Assistant Administrator Christian Holmes called water a common denominator for climate risk.

Researchers have been warning about future water scarcity for decades, but new data reveals a majority of the world’s largest aquifers are already running out of water.

With thousands of scientists representing 195 countries working for more than a quarter of a century, the Intergovernmental Panel on Climate Change (IPCC) is the world’s leading authority on of assessing climate change and its potential socio-economic impacts. However, Marc Levy, an IPCC lead author and deputy director of Columbia University’s Center for International Earth Science Information Network, says he’d have gone further in connecting climate change to conflict in their latest report if it were up to him.

A pair of recently launched data sources offers visualizations to help people understand two hot-button issues in demography: the demographic dividend and changing fertility rates.

In 1968, Stanford University biologist Paul Ehrlich predicted hundreds of millions would starve to death over the next decade, many of them Americans, and the world would generally decline into chaos in his book The Population Bomb.
