Reliable access to adequate food is a fundamental requirement for human life. Climate change, inefficient agricultural methods and limited resource capital are formidable challenges that many developing nations face as they cope with the scarcity or unpredictable changes in food availability combined with growing populations.

Reliable and sustainable food availability, food access, nutritional value and safety are important aspects of food security. Food Availability means there is a consistent local supply of appropriate food types, either imported or produced locally. Food Access means that the local population have the means to purchase or barter for the food they require for appropriate diet and nutrition. Available and accessible food must also be of sufficient nutritional value and be safe to consume if Food Security is to be attained. There should also be a stable supply and access to food for longer periods. This can be achieved with appropriate food production, handling and storage.
