This book is the result of a minor field work in a coastal Bangladesh village where peoples are struggling to adapt with salt water intrusion. It describes how people in one community under climatic change or variability adapt to an acute problem. To make sense my primary and secondary data I have used adaptation theories of anthropology more specifically how people respond to changing environment regard to livelihood. The perceptions on salinity, livelihood adaptation strategies, politics of adaptation and how their culture and nature are shaped by each other are developed in the body of this book. The study encompasses theoretically in a broad sense Ecological Anthropology and specifically cultural ecology and practically addresses adaptation to climate change impacts, a growing field in Anthropology known as 'Anthropology of Climate change'. This book could be an eye opener to policy makers and those who are enthusiastic to human dimension of climate change and how do people respond to that change in developing countries.
