The puzzle and the method

Studies on socio-economic impacts of climate change are divided on arguing whether climate change causes population movement or not. Some of the areas most vulnerable to climate change are small island countries and countries at lower altitudes because they are more prone to inundation because of the climate change-induced sea level rise. Among those at risk are the Pacific Island countries, Bangladesh, and the Maldives. This chapter describes the puzzle by focusing on a case study on Bangladesh. It also describes the method of data collection that includes field research in Bangladesh, which comprised elite interviews and a literature search. This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book showcases a literature review that contains existing debates in international climate change-related discussions about defining climate change-induced uprooted people. It presents a new theory – knowledge network theory – which contains conceptual and theoretical understandings of politics of climate change knowledge.
