Environmentalists from around the world gathered in Barcelona from October 5-14, 2008, to discuss issues impacting a sustainable world at the World Conservation Congress. ECSP Director Geoff Dabelko interviewed Wouter Veening, co-founder and chairman of the Institute for Environmental Security (IES) in The Hague, following his discussion of “Environment and Security Challenges for Change.” In this podcast, Veening discusses the impact of climate change on traditional security threats and the global implications of failing to effectively address this issue. Dabelko analyzes related environment-security links in a chapter in IES’s Inventory on Environmental and Security Policies and Practices, as well as in numerous Grist dispatches from the IES 2004 Hague Conference on Environment, Security, and Sustainable Development.
