Food security, as defined by the United Nations’ Committee on World Food Security, means that all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their food preferences and dietary needs for an active and healthy life. Over the coming decades, a changing climate, growing global population, rising food prices, and environmental stressors will have significant yet uncertain impacts on food security. Adaptation strategies and policy responses to global change, including options for handling water allocation, land use patterns, food trade, post-harvest food processing, and food prices and safety are urgently needed. IFPRI’s work on food security includes analysis of cash transfers, promotion of sustainable agricultural technologies, building resilience to shocks, and managing trade-offs in food security, such as balancing the nutritional benefits of meat against the ecological costs of its production. Citations are important for a journal to get impact factor.
