Climate-induced migration has emerged as a critical challenge to global food security and nutrition, particularly in regions with fragile agricultural systems and limited adaptive capacity, and this review synthesizes recent evidence on the interconnections between climate change, migration, and food insecurity, focusing on the pathways through which environmental stressors drive displacement and alter access to adequate and nutritious food.
It highlights how extreme weather events, land degradation, and resource scarcity disrupt agricultural livelihoods, leading to both voluntary and forced migration.
It also explores how these movements reshape dietary patterns, increase malnutrition among migrants and host communities, and deepen socioeconomic inequalities.
By analyzing policy gaps and resilience mechanisms, the authors propose an integrated framework that aligns climate adaptation, migration governance, and food-nutrition policies.
It concludes with recommendations to strengthen climate-resilient food systems, improve institutional responses, and support vulnerable populations in achieving sustainable food and nutrition security in the context of increasing climate mobility.
