Food security: its components and challenges

Food security relates directly to nutrition and health. Typically food security is thought of as being related to availability and access of foodstuffs. Yet, the threat to food security also lies with urbanisation, income disparity, overpopulation, ecosystem degradation, animal health, and food wholesomeness. Food wholesomeness is also an important aspect of nutrition. Wholesomeness is monitored via food safety and food defence programmes, making them critical components of a food security programme as well. This article discusses these interrelations and concepts for future scientific and humanitarian development programmes.
