Cataclysmic events such as vanishing coastlines, loss of territories, escalation of conflict over natural resources are projected to be some of the consequences of climate change. In some places, environmental disasters triggered by global warming have wreaked havoc on the lives of ordinary people who more often than not lack the tools, skills and resources to tackle the vagaries of nature. This chapter aims to discuss why India needs a policy for climate ‘refugees’ and how climate change can lead to cross-border migration. Migration spurred by climate change is worrisome as more and more persons are on the move as crops fail and water sources disappear. These migrants either face internal displacement or are compelled to migrate to another country in pursuit of safety and stability. The region of South Asia is especially vulnerable to climate change given its geographical location. In contemporary discussions about climate change-induced migration, it is often pondered whether environmental migrants fall within the scope of refugeedom. There are both merits and demerits of expanding the UNHCR definition of the refugee to include those fleeing across international borders due to climate change. India is a party to neither the 1951 Refugee Convention of the United Nations nor its 1967 Protocol, given their Euro-centric focus. Hence, it is in India’s interest to develop a homegrown definition for asylum seekers escaping from climatic disasters and to lay down a policy framework that encourages voluntary repatriation and third-country settlement while also pursuing sustainable modes of development.
