Sustainability means “meeting the needs of the present without compromising the ability of future generations to meet their own needs”. This really reflects the inextricable link between human health and planetary health. A sustainable food system is needed to support human health for a growing world population and to ensure positive impacts on the environmental, economic and social systems that surround food. Sustainable food systems must include the development of sustainable agricultural practices, development of more equitable food distribution systems, evolution towards sustainable diets and reduction of food waste throughout the system. The Sustainability Portal is dedicated to provide basic concepts of different areas where support to sustainable actions can make a difference for humans and the planet.
