Abstract

This paper aims to assess the nexus of food insecurity, climate change and migration in the developing world. The world is experiencing triple challenges of food insecurity, climate change and unprecedented migration. Food insecurity as a result of climatic variabilities has a likelihood of pushing people to migrate. Interlinkages between food insecurity, climate change and human mobility should be recognised. The methodology employed in this paper is a literature review, specifically an Integrative literature review of all sources related to the topic under investigation. Findings of the study point to the fact that most of the world's poor rely on subsistence farming for their livelihood, yet this industry is particularly vulnerable to the effects of climate change. Adverse shocks to agricultural productivity due to climate changes significantly increase emigration from developing countries, with a more significant impact in low-income countries and a smaller one in middle-income countries. Key Words:Food insecurity, Climate change, Developing countries, Environmental shocks, Migration
