The main argument presented in this monograph is that Security in the Anthropocene epoch will have to shed its conservative assumptions about ‘Nature’ as a stable backdrop to geopolitics and the states in the Global South, particularly a vulnerable region like South Asia, much like their earlier efforts at the framing of environmental problems through the lens of equity, distributive justice, and post-colonial as well as regional alliances such as G-77, SAARC, BIMSTEC, will have to actively engage in the climate security debates and explore new methods of climate change governance and cooperation at the regional scale.
