Climate change significantly impacts food systems, which are crucial for food security. Food systems encompass food availability, access, and utilization, and their integrity is essential for ensuring that all people have access to sufficient, safe, and nutritious food. Climate change affects food systems through various mechanisms, including changes in crop production, market dynamics, and supply chain infrastructure. The relative importance of climate change to food security varies by region, with southern Africa being particularly vulnerable due to the combined effects of climate and other factors like conflict and HIV/AIDS. In contrast, regions like the Indo-Gangetic Plain face challenges from labor issues and water availability. Food systems are influenced by multiple socio-economic and bio-physical factors, leading to varying levels of vulnerability to climate change. Adaptation strategies are necessary to reduce this vulnerability, including improving food production, distribution, and economic access. However, these strategies must also consider environmental sustainability to avoid exacerbating climate change. For example, intensifying agricultural production can reduce emissions but may also lead to environmental degradation if not managed properly. Adaptation efforts must address the complex interactions within food systems, including the need for sustainable practices that reduce greenhouse gas emissions and enhance resilience. Regional and global policies are essential to support these adaptations, ensuring that food systems can withstand climate and other environmental changes. The paper highlights the importance of integrated research and policy frameworks to address the multifaceted challenges of food security in the context of climate change.Climate change significantly impacts food systems, which are crucial for food security.
