The pursuit of providing the people of the world with available, accessible, nutritionally adequate, safe food is a technical problem. Food sovereignty is a different issue. Food sovereignty is a concept that emphasizes the right of people, communities, and countries to define their own agricultural, labour, fishing, food, and land policies that are ecologically, socially, economically, and culturally appropriate to their unique circumstances. It prioritizes local food production and consumption, ensuring that food systems are controlled by local producers rather than multinational corporations. Agroecology provides a systematic solution to food security, but this chapter explores the connection between agroecology and food sovereignty by defining agroecology as a science, a practice, and a social movement. It also revisits the original concept of agriculture from Chap. 1 , where agriculture is defined as a unique life support industry, integrating politics into agroecology and providing an institutional guarantee for food sovereignty.
