The Center for Strategic and International Studies in Washington DC (CSIS) and the Development Gateway have partnered to develop two new online communities: Stabilization and Reconstruction and Disaster Prevention and Response. These portals will provide a virtual space where participants can share knowledge, lessons learned, best practices, and other information in an effort to build capacity, strengthen working relationships, and improve development outcomes in these areas. Social networking tools will be used to bring disparate actors together in a common forum where issues of mutual interest can be discussed and problems solved. In particular, both portals will address the unique challenges of civil-military coordination in post-conflict and disaster response scenarios. Particular emphasis will be placed on bringing together non-traditional partners, including government agencies, international organizations and NGOs in both developed and developing countries.
