Food systems are intimately linked to our lives – through the food we eat, our nutrition and health, our livelihoods, jobs, and the environment and natural resources of the planet. The main challenge for food systems is to produce nutritious food for all while preserving our biodiversity and environment and ensuring equitable distribution of wealth. This brief provides a summarized version of the methodology used to conduct a global assessment of food systems in over 50 countries, following a joint initiative by the European Union (EU), Food and Agriculture Organization of the United Nations (FAO) and the International Cooperation Centre of Agricultural Research for Development (CIRAD) aiming to catalyze the sustainable and inclusive transformation of food systems.
