Climate Change and Migration: Food Insecurity as a Driver and Outcome of Climate Change-Related Migration

Abstract

The impacts of human-induced climate change on both population mobility and food security are issues of substantial concern and debate. However, there has been limited consideration of the intersections between these processes. This chapter considers two key areas of concern. First, climate change will adversely affect food security in many regions, and this may contribute to migration where, for example, people move to areas where agricultural livelihoods and food sources are more secure. Second, climate change is projected to cause increases in human population movement in coming decades, and the nature of some anticipated migration pathways may lead to food insecurity in sites of settlement and relocation. However, the effects of climate change on both population mobility and food security will occur through complex pathways. This chapter considers the intersections-both potential and current-between climate change, food security and migration.
