This publication discusses the activities and findings from the second phase of the Asian Cities Climate Change Resilience Network (ACCCRN), a program supported by the Rockefeller Foundation. Changes in climatic conditions represent one of the greatest challenges facing humanity over coming decades. Climate change poses special concerns for the rapidly growing cities of Asia, where large populations, rapid urbanization, extensive poverty and social marginalization, and an already high level of exposure to climatic extremes create risks for large numbers of people. The impacts of climate change are likely to be particularly severe for poor and marginalized populations.
