Climate change poses unprecedented challenges to global food security by disrupting agricultural systems, reducing crop yields, and intensifying resource scarcity. Rising temperatures, erratic rainfall, soil degradation, and increasing frequency of extreme weather events threaten the stability of food supply chains, particularly in vulnerable regions. The central problem lies in balancing rising global food demand with diminishing natural resource availability and climate-induced risks. The objective of this study is to examine adaptive strategies that enhance food security in a warming world, focusing on resilience, sustainability, and policy integration. Methodologically, the study synthesizes findings from climate-agriculture models, case studies across diverse agro-ecological zones, and policy analyses to evaluate both technological and institutional responses. Results reveal that climate-smart agriculture, improved water management, diversification of crops, and the adoption of digital technologies significantly increase resilience, while social protection programs and regional cooperation buffer communities against food insecurity. The discussion highlights that although scientific and technological advances provide opportunities, structural inequalities, governance gaps, and limited investment often constrain adaptation. Policy implications emphasize the need for integrating climate adaptation into agricultural planning, incentivizing sustainable farming practices, strengthening food trade policies, and expanding support for smallholder farmers. In conclusion, ensuring food security in a warming world requires a multi-dimensional approach that combines innovation, inclusive policy frameworks, and global collaboration to build climate-resilient food systems capable of feeding future generations.
