Abstract
Climate migration has emerged as one of the most pressing socio-political and humanitarian challenges of the twenty-first century particularly in regions characterized by ecological fragility high population density economic vulnerability and developmental asymmetries such as South Asia. The intensification of climate-related hazards including sea-level rise glacial melt erratic monsoons cyclones floods droughts salinization and extreme heat events has significantly disrupted traditional livelihoods agricultural productivity water security and habitat sustainability across countries such as Bangladesh India Pakistan Nepal Sri Lanka Bhutan and the Maldives. These environmental stressors when interacting with pre-existing socio-economic inequalities weak governance structures rapid urbanization and demographic pressures generate complex mobility patterns that range from seasonal labor migration to permanent displacement and cross-border movements. Climate migration in South Asia is not merely an environmental phenomenon but a multidimensional human security concern affecting food security health security economic stability personal safety community cohesion and political stability. The concept of human security which shifts the focus from state-centric security paradigms to the protection of individuals and communities provides a comprehensive analytical framework to understand how climate-induced displacement exacerbates vulnerabilities while also reshaping regional geopolitics and social relations. Despite increasing scholarly attention significant gaps remain in integrating environmental change migration governance and human security within a unified analytical model tailored to the South Asian context. This research paper seeks to examine the drivers patterns and implications of climate migration in South Asia through the lens of human security exploring how environmental stress intersects with structural inequalities to produce layered insecurities while also identifying adaptive capacities policy innovations and regional cooperation mechanisms that can mitigate adverse outcomes. By synthesizing theoretical insights empirical evidence and policy analysis this study aims to contribute to the evolving discourse on climate justice sustainable development and resilience-building in one of the world’s most climate-vulnerable regions.
