Climate change has already impacted on innumerable communities, exposing them to increasing hazards and making them more vulnerable; and we can expect this to become more marked, and for some communities catastrophic, in coming years. In order to plan effective adaptation actions, scientific climate change analysis is vital for broad context. However, at the local level, the most relevant information and knowledge often already exists or can be generated through local stakeholders’ own analysis. Local knowledge also has a credible authority for informing and influencing policy. So this Handbook, which presents a new participatory methodology for Climate Vulnerability and Capacity Analysis, is very timely. Its focus on the community level is sharp and salutary. It stresses that communities are not homogeneous.
