Environmental Change and Migration: Legal and Political Frameworks

Abstract

With this paper I focus on international legal norms and organizational roles and relations applicable to migration induced by environmental change. I examine movements stemming directly and indirectly from environmental factors related to climate change—including, for example, movements resulting from intensified drought and desertification affecting livelihoods, rising sea levels, intensified acute natural disasters, and competition for resources that result in intensified conflict. The analysis focuses on the extent to which legal and institutional responses affect patterns of mobility, especially in slow-onset situations, and the extent to which governance, more generally, affects the likelihood that people will migrate as a result of environmental factors, especially in humanitarian emergencies. I conclude that immigration policies, governance, and the level of development in affected countries play a crucial role in determining the responses to natural hazards and conflict. They also help determine if migration poses technical or managerial challenges or presents political challenges. Given the current gaps in appropriate migration policies, more attention needs to be placed on identifying and testing new frameworks for managing potential movements. Attention needs to be given to both sides of the environment and migration nexus: (1) identifying adaptation strategies that allow people to remain where they currently live and work; and (2) identifying migration and relocation strategies that protect people's lives and livelihoods when they are unable to remain.
