Some 52 percent of the world’s population lives in cities, a proportion that will only grow throughout the next few decades. Understanding the health challenges facing urban residents is crucial for those who seek to improve human health, especially since many of these challenges differ from those facing inhabitants of rural areas, where global health resources have traditionally been concentrated. At a private meeting on March 4 at the Wilson Center, experts described how factors ranging from climate change and greenhouse gas emissions to reproductive health and rights impact urban health.

We need to understand why barriers to trade exist in order to alleviate the food insecurity that confronts Africa, said Makhtar Diop, World Bank vice president for Africa, at the Wilson Center in January.

The World Bank released a new report in October 2012 that is part of a series that concentrates on intraregional trade. Africa Can Help Feed Africa: Removing Regional Barriers to Trade in Food Staples, however, is unique, Diop said, because it “moves the focus from general barriers to trade in Africa to focus on food,” so that policymakers can move away from crisis response and address food insecurity at a base level. [Video Below]

Dialogue at the Wilson Center tackled demography and the environment last week, interviewing Pulitzer Prize-winning journalist and former Wilson Center public policy scholar Caryle Murphy about her new book, A Kingdom’s Future: Saudi Arabia Through the Eyes of Its Twentysomethings, followed by John Sullivan, director of the Environment and Health and Safety News Division for Bloomberg BNA, on the most important energy and environmental issues of 2013.

The conversation around immigration and Mexico has long been tied to the United States and the prevailing economic conditions in both countries. But a new report from the Royal United Services Institute argues that as temperatures rise and precipitation patterns change over the course of the next century, climate too will increasingly become a driver of both internal and international migration in Mexico. [Video Below]

Climate change and conflict can create a self-reinforcing feedback loop: Climate change exacerbates existing conflicts, while conflict makes adapting to climate change more difficult, said Janani Vivekananda of International Alert at the Wilson Center on February 7. [Video Below]

“We are in the midst of a silent revolution,” said Ann Pawliczko, a senior technical advisor in the population and development branch at the United Nations Population Fund (UNFPA), quoting former UN Secretary-General Kofi Annan. “It is a revolution that extends well beyond demographics, with major economic, social, cultural, psychological, and spiritual implications.”

Environmental desks at newspapers around the world may be on the defensive, but the stories are only getting bigger. On January 25, six environmental journalists from Bloomberg, EnergyWire, Public Radio International, the Associated Press, and the Yale Forum on Climate Change and the Media gathered at the Wilson Center for a panel cosponsored by the Environmental Change and Security Program and the Society of Environmental Journalists to discuss what to watch for in the coming year, from President’s Obama’s mention of climate change in his inaugural address to the prospects of shale gas and the Keystone XL pipeline.
