Research on the impact of climate change on food security in Africa.

ABSTRACT: Global warming and the rising frequency of extreme climate events pose significant threats to food security. We examine the influence of climate change on food security in Sub-Saharan Africa, with a specific emphasis on four key crops: maize, rice, wheat, and soybeans. We employ a random forest model to estimate spatial and temporal yield trends based on climate variables, land‑use patterns, and irrigation ratios. We also studied the differential impacts of climate change on various crop types, taking into account their physiological characteristics and responses to changing environmental conditions. This prediction is performed under three Shared Socioeconomic Pathways (SSP2‑4.5, SSP3‑7.0, SSP5‑8.5)-using five global climate models (GCMs): BCC-CSM2-MR, CanESM5, IPSL-CM6A-LR, GFDL-ESM4 and
