Poor people bear the brunt of climate change since they live in those regions most affected by fluctuating temperatures, sea level rise, flooding and drought. Far from behaving as victims, however, they use the assets and resources at their disposal to adapt and survive. Nevertheless, to plan effective adaptation people need to appreciate that potentially profound changes are in store, yet that climate predictions are deeply uncertain. "Understanding Adaptation to Climate Change" combines eight case studies from south Asia, Africa and Latin America with an overall framework. The analysis demonstrates that although communities' adaptation strategies may be varied and depend on local context, social networks play a pivotal role in accessing appropriate climate knowledge and resources and communicating useful approaches to other communities. The key activities of reducing vulnerability, fostering resilience and developing the capacity to experiment and learn are combined as appropriate. This book asks, how can agencies assist local communities adapting to change? By what mechanisms can communities make the most of emerging information? Can effective community-based approaches be scaled up? This book is essential reading for NGO practitioners, students and government and NGO policy makers who wish to gain an understanding of what adaptation means in theory and practice.
