Environmental Effects on Sustainable Food Production Affecting Food and Nutrition Security

Food and Nutrition security concerns the physical, social, and economic approach towards necessary safe and nutritious food. Food security lay on four pillars: availability, access, utilization, and stability. Food is important for human existence. Various steps have been taken in addressing the global undernutrition over the past several decades, specifically by enhancing food production from agriculture expansion and strengthening. Food Production, food system continues to face a surge in demand and growing environmental difficulties. Most significantly, climate change is causing the quality and quantity of food. The dimensions to confirm food security and nutritional adequacy in the aspect of rapidly altering biophysical conditions will be major element of global burden of disease. Many such consequences of environmental change damage the permanency of worldwide food system, decreasing food security. This chapter entails the environmental impact at different levels, involving alteration in soil fertility and crop yield, bioavailability of nutrients in foods.
