This English brochure develops a vision for the food system in Flanders, Belgium in 2050.
See http://do.vlaanderen.be/content/flemish-sustainable-development-strategy-english-brochure

“The food system (food production, processing, distribution and consumption) guarantees the right to food, as well as sufficient, safe, balanced, healthy and affordable food for all world citizens, respects the principles of food sovereignty, is in balance with the limited space for environmental use (water, soil, air, space, energy), reinforces regional development and spatial quality, and respects the cultural identity of food. Food demand and supply (production, processing, marketing) are balanced. The aim is to provide regional food systems (per partial continent) in a closed cycle as the basic system. Food can be produced in rural regions, peri-urban regions and in town. Dignified work conditions, honest prices and a worthy income are guaranteed to all actors of the food chain. The end price of a product not only internalises all production costs but also all social and environmental costs.”
