Uncovering the numerous variables that can influence global climate change can be daunting. Brian O’Neill and his colleagues are improving our understanding of some of these factors by modeling how demographic shifts—such as aging or urbanization—could impact climate change. O’Neill is a scientist at the National Center for Atmospheric Research’s Institute for the Study of Society and Environment in Boulder, Colorado, and also leads the Population and Climate Change (PCC) Program at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria. Researching population-environment interactions and the science and policy of global climate change led to O’Neill’s recent work as a lead author for the Intergovernmental Panel on Climate Change‘s Fourth Assessment Report. In this podcast, O’Neill describes how shifting demographic patterns could influence a changing climate.

Effective development programs require multisectoral strategies, says Roger-Mark De Souza, and succeed by building local and regional partnerships and winning the trust and participation of individuals and communities. In the following podcast, ECSP Director Geoff Dabelko discusses integrated development approaches in the Philippines with De Souza, who is the director of foundation and corporate relations at the Sierra Club and formerly the technical director of the Population Reference Bureau’s population, health and environment program. De Souza shares his experiences of how local communities have successfully integrated environmental conservation and population issues to alleviate poverty and improve their quality of life. Many of the issues regarding integrated population, health, and environment approaches discussed in this podcast also appear in an article by De Souza in ECSP Report 10.

By destabilizing environments, global climate change can exacerbate existing security challenges and contribute to the creation of new ones. A widely publicized November 2007 report by the Council on Foreign Relations examines the linkages between climate and security and proposes a manageable set of policy options to adapt to and reduce the impacts of an inevitable global change in climate. The report, entitled “Climate Change and National Security,” was written by Joshua Busby, an assistant professor at the Lyndon B. Johnson School of Public Affairs at the University of Texas, Austin. In Part 1 of a two-part podcast series, ECSP Director Geoff Dabelko speaks with Busby about the report and his recommendations for action.

The Population Institute’s annual Global Media Awards (GMAs) honor journalists covering the numerous connections between population issues and development. Each year, GMA honorees visit Washington, DC, to present their award-winning projects to inside-the-beltway audiences and network with policymakers, NGOs, and each other. I had the chance to chat with two of this year’s GMA winners: Melclaire Sy Delfin, winner of the Best Individual Reporting category, and Jim Motavalli, winner of the Best Magazine Article award. Delfin is a television reporter with the Philippines’ GMA Network, Inc., and was recognized for her two in-depth investigative reports, “The Forbidden Games Filipino Children Play” and “When Wells Run Dry: A Tragedy Looming Large.” Motavalli is the editor of E/The Environmental Magazine; his winning article showed that falling birth rates are largely confined to developed countries, and that population growth remains high in many African and Asian countries.

Henrik Urdal, a senior researcher at the International Peace Research Institute, Oslo (PRIO), spent several weeks at the Woodrow Wilson Center this autumn as a visiting fellow. At PRIO, Urdal researches the relationships between demography and armed conflict, focusing particularly on population pressure on natural resources. ECSP Director Geoff Dabelko sat down with Urdal to discuss his current research interests, including the implications of a rapidly urbanizing global populace, sub-national demographic trends in India, and the extraordinary Iranian fertility decline.

During a recent trip to Costa Rica, ECSP Director Geoff Dabelko visited Alexander Lopez, director of the School for International Affairs at the National University of Costa Rica. With his extensive field work, Lopez is an expert on the linkages between environment and conflict, as well as the management of transboundary river basins in Latin America. In the following podcast, Lopez discusses the growing awareness of environment and security linkages in Central America and his current work on building regional cooperation and integration of natural resource management.

I recently traveled to Ethiopia to attend “Population, Health, and Environment: Integrated Development for East Africa,” a conference sponsored by the Population Reference Bureau (PRB) and LEM Ethiopia. The conference was attended by more than 200 development practitioners from around the world, including many from Rwanda, Uganda, Tanzania, Kenya, and Ethiopia.

Our notion of security has evolved in the years since September 11th, with increasing attention being given to understanding the underlying causes of conflict and state failure. Colin Kahl, an assistant professor in Georgetown University’s School of Foreign Service and a fellow at the Center for a New American Security, argues that these underlying causes of conflict can include—but are not limited to—demographic change, environmental degradation, and poverty.
