A range of pressures including rapid population growth, urbanization, growing wealth and consequent changes in consumption patterns, are challenging our food systems’ ability to provide nutritious food, and to contribute to enhanced livelihood opportunities  in an environmentally sustainable way. Our food systems are contributing to, and affected by, extreme weather events as associated with climate change, land degradation and biodiversity loss. Responding to these challenges requires a systems-based approach that addresses the range and complexities in a holistic and sustainable manner.

A sustainable food system is one that delivers food security and nutrition for all in such a way that the economic, social and environmental bases to generate food security and nutrition for future generation is not compromised. This means that it is profitable throughout, ensuring economic sustainability, it has broad-based benefits for society, securing social sustainability, and that it has a positive or neutral impact on the natural resource environment, safeguarding the sustainability of the environment.
