From: Towards sustainable diets and farming systems through land use optimisation
This figure shows the percentage of food self-sufficiency (FSS), meaning the average ratio between production and the territory’s needs for each food category, achieved in Wallonia across six combined diet and farming system scenarios, modelled under two food waste assumptions: 30% (left panel) and 10% (right panel). The optimisation model allocates crops across agricultural regions to best align food production with local consumption needs for each scenario. The diets considered are CURRENT, EAT–LANCET, and TYFA, each evaluated under both conventional and organic farming systems. Scenario distinctions are indicated by colour and pattern: orange bars for conventional farming, green bars for organic; plain bars represent the CURRENT diet, dotted bars EAT–LANCET, and striped bars TYFA.
