The significance of bottom-up approaches initiated by civil society as well as the importance of the local level as the level for implementation is often overlooked when dealing with megacity developments. The main aim of this volume is to retrospectively trace participatory and local action approaches to climate change adaptation and mitigation in urban areas from seven case studies of the program. By bringing together experiences gained from pilot projects and action research, the volume narrates the "stories behind" individual activities and co-operation processes, illustrates ingenuous results and lessons learned, and formulates overarching conclusions and recommendations for future participatory field research and realisation of urban development projects.
