Abstract
Researchers have long hypothesized complex linkages between migration, food security, and climate change. But the empirical evidence connecting these processes has not been systematically assessed. The objective of this review is to identify gaps and common themes in existing empirical analysis, modeling paradigms, and policy frameworks focused on the mechanisms influencing the climate-food security-migration nexus. The review was accomplished by completing a systematic search of the Web of Science for literature published since 2010 that fit the selection criteria, with a total of 94 relevant publications selected. The process took place in two stages. The first stage analyzed literature focused on how climate change and variability impacts food security. Our review found that the literature is predominantly concerned with climate influences on crop production, with a lesser focus on climate impacts on food prices, consumption, and accessibility. The second stage analyzed literature focused on the dynamics between climate-induced links between food insecurity and migration. The core hypothesized linkages that form climate-food-migration nexus is that rural livelihoods are vulnerable to negative climate events, that in turn may drive rural-to-urban migration. Yet, scant empirical evidence exists to support or refute this hypothesis. Furthermore, current research overlooks the food security status of migrants in urban destinations and does not assess how climate variability impacts origin versus destination food security status. The findings of our review suggest further research is needed to improve the understanding of how climate change and variability link to migration patterns and food security outcomes.
