The papers in this Special Issue cover a range of geographies, themes, and methods, but converge on a shared insight: that climate change is profoundly shaping food systems, forms of human mobility, and household food security. Across the African continent, accelerating climate change is transforming weather patterns, intensifying extreme weather events, creating urban heat islands, and eroding land and water resources. These shifts are reinforcing existing inequalities and socio-economic divides, affecting where people live, how they access food, and the types of mobility and immobility they engage in. Doomsday scenarios about climate catastrophe, famine, and mass migration have increasingly given way to more nuanced views in which both the capacity to move and the factors that constrain movement are seen as livelihood strategies for resilience and adaptation. While climate change and food insecurity are increasingly recognised as drivers of internal and international migration, migration is a key strategy that redistributes risk and resources and can mitigate food insecurity. Therefore, the analysis of climate change and food insecurity as migration drivers needs to be leavened with the lived experiences, responses, and strategies of those most affected. These case studies converge on a shared insight: that is, climate change is profoundly shaping food systems, forms of human mobility, and household food security.
