Twenty-five percent of the world’s population live in South Asia, one of the most climatically vulnerable regions. The impact of climate change on migration and displacement is not sufficiently recognized by policymakers. International frameworks and national strategies need a crucial link that recognizes the interaction between the impacts of climate change on extreme weather events, environmental degradation, and human migration. This raises concerns that climate change is becoming a significant factor in displacement and that the number of people displaced globally due to war and conflict is almost the same. This is partly because migration and climate change are difficult to separate and measure, despite their strong correlation. Nevertheless, the number of migrants caused by climate change will increase. South Asian migrant countries are experiencing hardship and displacement. The secondary literature serves as the basis for the study. According to the study, there is direct displacement of people due to climate change or exacerbation of distress leading to distress migration in South Asian countries. Climate change mitigation and adaptation initiatives as well as national, regional, and international policy measures are urgently needed to ensure the rights of displaced people to humanitarian assistance and social legal protection. Despite the methodological differences and statistical intensity of climate migrants, the crises exist in their own way. However, concerted efforts are needed from all these actors, the directly affected population, and the willingness of policymakers to address the problems in order to take immediate action to alleviate the suffering.
