评估城市农业粮食系统的可持续性严格与粮食供应能力挂钩。特别是在农业持续承压的大都市地区，深化结构变化对经济和政策的影响尤为重要。在这一视角下，本文提出使用优化模型来说明如何在区域层面协调农业活动和粮食需求的遵守情况。该方法依赖于通过线性规划模型进行的情景分析。关于米兰大都会地区，根据不同的生产能力或饮食习惯，执行了五个方案，并根据这些调整恢复了农业资源的最佳分配。
Assessing the sustainability of urban agro-food systems is strictly linked with food provision capacities. Especially in metropolitan regions, where agriculture is continuosly under pressure, deepening economic and policy implications of structural changes is particularly important. In this perspective, the paper proposes the use of an optimization model to indicate how reconciling agricultural activities and compliance with food demand at regional level. The approach relies on a scenario analysis carried out through a linear programming model. With regard to the Milan metropolitana area, five scenarios are performed, related to either different productive capacities or dietary habits, and the optimal allocation of agricultural resources in response of such modifications is returned.
