This study examines the inter linkages between climate change, disaster risk, and the urban poor. This study calls on cities to take a lead role in proactively addressing the risks of climate change and natural hazards at the local level, with a focus on populations at highest risk. It suggests a number of actions that cities can take to build resilience, beginning with mainstreaming pro-poor risk reduction policies into urban planning and management. The study: analyses the key challenges facing the urban poor, given the risks associated with climate change and disasters; identifies key strategies that cities can pursue to build resilience for their vulnerable populations; and gives examples of policies and programs that have been implemented at the city level—including a review of financing options for local governments.
