人们对城市粮食生产的兴趣日益浓厚;最近的研究强调了其在提高粮食安全和减少粮食生产对环境影响方面的潜力。然而，对城市园艺的资源需求知之甚少。在这里，我们使用分配花园在英国调查全国各地的城市园艺生产的资源需求。我们进行了一个全国性的公民科学项目，使用长达一年的分配“日记”与分配园丁（n = 163）。我们分析了各种资源：运输;时间;水的使用;堆肥，粪肥和表土的投入;以及肥料，害虫控制和杂草控制的投入。我们发现，总的来说，一个分配需要87个年度访问，往返139公里的地块; 7个肥料添加; 4个害虫控制添加;和2个杂草控制添加。平均而言，每生产一公斤食物需要0.4小时的劳动、16.9升的水、0.2升的表土、2.2升的粪肥和1.9升的堆肥。随着人们对城市园艺生产的兴趣越来越大，政策制定者将城市园艺空间建设成未来的可持续城市，以最大限度地减少资源需求的方式进行这一工作至关重要，我们在这里展示了将城市可堆肥废物和家庭级城市食物垃圾用于此目的的途径。
Interest in urban food production is growing; recent research has highlighted its potential to increase food security and reduce the environmental impact of food production. However, resource demands of urban horticulture are poorly understood. Here, we use allotment gardens in the United Kingdom to investigate resource demands of urban horticultural production across the country. We conducted a nationwide citizen science project using year-long allotment 'diaries' with allotment gardeners (n = 163). We analysed a variety of resources: transportation; time; water use; inputs of compost, manure and topsoil; and inputs of fertilisers, pest control and weed control. We found that, overall, an allotment demands 87 annual visits, travelling 139 km to and from the plot; 7 fertiliser additions; 4 pest control additions; and 2 weed control additions. On average, each kilogram of food produced used 0.4 hours' labour, 16.9 L of water, 0.2 L of topsoil, 2.2 L of manure, and 1.9 L of compost. As interest in urban horticultural production grows, and policy makers build urban horticultural spaces into future sustainable cities, it is of key importance that this is carried out in a way that minimises resource requirements, and we demonstrate here that avenues exist for the diversion of municipal compostable waste and household-level city food waste for this purpose.
