Community-Based Adaptation to Climate Change

International efforts to reduce and sequester carbon dioxide and other green-house gases are not yet slowing the rate of global warming. Indeed, the Fourth Assessment Report of the Intergovern-mental Panel on Climate Change (IPCC) anticipates rapid changes in climate even if the greenhouse-gas emissions are reduced quickly,1 and recent findings suggest that these projections are underestimated.2 The impacts of climate change will be severe, particularly for the most vulnerable developing countries that have the least capacity to cope. As a result, the need to support adaptation in developing countries is growing in urgency.
