Developed for local and national-lelvel practititioners interested in community-based adaptation (CBA) to climate change, this guide presents the lessons and practices from the gloal pilot project funded by the Global Environment Facility (GEF) under the Strategic Priority on Adaptation (SPA) window and implemented by the United Nations Development Programme (UNDP) through the GEF Small Grants Programme (SGP) mechanism.   The guide resembles a \'cookbook\' for conducting the CBA processes in project development and implementation. To illustrate the processes and priniciples, the guide provides practical examples of how CBA can be accomplished in real project situations by drawing on the field experiences of the SPA CBA project, which was implemented in 10 countries in varying geographic areas with communities of different cultural backgrounds and norms.
