Around 40 percent of Bangladesh’s population are poor people for whom a variable and unpredictable climate can critically restrict livelihood options. This is true in rural and urban areas alike, but this study focuses on the latter. Urban poverty continues to be neglected in research, policy and action for climate change adaptation in the country. The study builds on three propositions:  poor urban communities are places where physical and socioeconomic vulnerability coincide;  urban areas are exposed to three forms of climate change impact: rapid-onset events, gradual-onset processes, and cascade effects; and  poor urban people are already adapting to emergent climate change impacts by actively developing various practices.
