By 2050, there will be at least nine billion people in the world to be fed, and two-thirds of them will live in cities. A before-after assessment of an urban horticulture scenario is presented to address the negative impacts of goods distribution within cities. A baseline scenario for the current food system is compared with the proposed one, adapted to local production and consumption through a case study for Belo Horizonte (Brazil). A Life Cycle Assessment was considered to estimate the potential environmental impact reduction by implementing a local production and consumption model. The Ecoinvent dataset 3.5, exiobase2, and the CML impacts methods were used. The potential of global warming, acidification, photochemical oxidation, and human toxicity was determined for both scenarios. Moreover, fuel, infrastructure, and vehicle consumption concerning the changes among the settings were compared. All categories of environmental impact presented significant reductions regarding the changes among scenarios for the distribution of vegetables. This paper brings a phenomenological contribution to Belo Horizonte's city, which can be considered to subsidize public policy decision-making to support urban agriculture.

到 2050 年，世界上至少有 90 亿人需要养活，其中三分之二将生活在城市。提出了对城市园艺情景的前后评估，以解决城市内商品分配的负面影响。通过对贝洛奥里藏特（巴西）的案例研究，将当前粮食系统的基线情景与提议的情景进行了比较，以适应当地的生产和消费。生命周期评估被考虑通过实施本地生产和消费模型来估计潜在的环境影响减少。使用了 Ecoinvent 数据集 3.5、exiobase2 和 CML 影响方法。两种情景都确定了全球变暖、酸化、光化学氧化和人类毒性的潜力。此外，燃料、基础设施、并比较了有关设置之间变化的车辆消耗。所有类别的环境影响都显着减少了蔬菜分布情景之间的变化。本文为贝洛奥里藏特的城市带来了现象学的贡献，可以认为是补贴公共政策决策以支持都市农业。
