In this overview paper the authors describe how community-based approaches to climate change have emerged, and the similarities and differences between CBA and other participatory development and disaster risk reduction approaches.

The relationship between climate change and cities is complex. City-based activities contribute significant amounts of greenhouse gases and, simultaneously, are often more vulnerable to the impacts of climate change. Dhaka is now the world's eighth largest city and a significant proportion of Bangladesh's greenhouse gases are generated there although, relative to total emissions worldwide, the contribution is negligible.
