Legal Responses to Climate-Induced Migration and Displacement: National and International Perspectives

Abstract

Climate change has emerged as one of the most significant drivers of human mobility in the twenty-first century, contributing to displacement through rising sea levels, extreme weather events, desertification, droughts, floods, coastal erosion, and ecosystem degradation. Millions of people are compelled to leave their homes each year due to climate-related disasters and gradual environmental changes, creating complex legal, humanitarian, and policy challenges at both national and international levels. Despite the increasing scale of climate-induced migration, international law does not formally recognize "climate refugees" under the 1951 Refugee Convention, leaving many displaced persons without adequate legal protection. National governments have adopted varying legal and policy responses, including disaster management frameworks, climate adaptation strategies, relocation programmes, and social protection measures. International organizations such as the United Nations, the International Organization for Migration (IOM), the United Nations High Commissioner for Refugees (UNHCR), and the United Nations Framework Convention on Climate Change (UNFCCC) have developed non-binding principles and cooperative mechanisms to address climate-related displacement. This paper critically examines the legal responses to climate-induced migration and displacement from both national and international perspectives by analyzing existing legal frameworks, human rights obligations, disaster governance, and emerging policy developments. It further evaluates the challenges associated with legal recognition, state responsibility, international cooperation, and protection of vulnerable populations while proposing reforms aimed at strengthening climate justice, human rights protection, and sustainable governance in an era of increasing environmental displacement.
