Sustainable Food Systems

Transition to sustainable food systems is essential to end hunger, malnutrition and poverty while preserving the environment.

Brief me

Many food systems are unsustainable and fail to ensure food security and to offer affordable nutritious and healthy diets.

Globally, food systems are a major driver of biodiversity loss and climate change, responsible for 30% of the world’s GHG emissions.

To raise awareness on the urgency of food system transformation, and foster commitments for concrete actions, the UN convened a Food System Summit in 2021.  Many countries have elaborated National Pathways containing priority actions for the transformation towards more sustainable and resilient food systems.

Development paths followed by high-income countries are generally not replicable in low- and middle-income countries, as they are not sustainable.

Scaling-up nature-positive production approaches, reducing food loss and waste, adopting healthy diets, better income and wealth distribution, and improved governance are among the most powerful enablers of the transition towards sustainable food systems.
