A variety of urban food production strategies have been proposed to reduce energy required to provide food to urban residents, reduce flooding, increase water reuse, increase biodiversity in cities, improve supplies of healthy fresh food to urban residents, and stimulate economic development. However, the water, nutrient, and energy requirements of urban food production have not been determined, and the resulting impacts on flooding and water quality have not been documented. To meet these needs, this project will instrument and monitor three urban agriculture demonstration sites in the Chicago area, and use the resulting data to assess the effects of alternative urban food production strategies on water, energy, and nutrients in cities. The project will 1) develop a general techno-economic life-cycle modeling framework for urban food systems, 2) monitor water, energy, nutrient, and carbon balances in urban food production, 3) develop physically-based models for hydrologic and biogeochemical dynamics at these sites, and 4) integrate these data and process models into the techno-economic model in order to compare whole-lifecycle energy, water, nutrient, and carbon impacts of alternative urban food production strategies relative to each other and to conventional production of the same crops. Very little data are available to quantify the water, energy, nutrient, and carbon requirements and impacts of urban food production. The projectwill yield novel data enabling parameterization of both process-based and techno-economic models for three alternative urban food production strategies. The project will be conducted in collaboration with the Chicago Botanic Garden through the Windy City Harvest program (WCH). This collaboration will engage apporoximately 200 students (grades 9-14) and community members per year in project science activities, and enable direct use of project results to improve design and operation of urban food production facilities. The project will also involve a student-science effort at Northwestern University, thereby engaging approximately 700 undergraduate students per year to analyze metals concentrations in samples obtained from WCH sites. Overall, the project will provide capability to estimate the magnitude of potential impacts that could be achieved by deploying urban food production at regional scales, along with information needed to design these production systems and optimize their location within urban landscapes, and engage approximately 2,000 students and community members in analysis and development of sustainable urban food production.

已经提出了各种城市粮食生产策略，以减少为城市居民提供粮食所需的能源，减少洪水，增加水再利用，增加城市的生物多样性，改善对城市居民的健康新鲜食品的供应，并刺激经济发展。但是，尚未确定城市粮食生产的水，养分和能源需求，因此尚未记录对洪水和水质的影响。为了满足这些需求，该项目将在芝加哥地区进行工具和监视三个城市农业演示地点，并使用结果数据来评估替代城市粮食生产策略对城市水，能源和养分的影响。 The project will 1) develop a general techno-economic life-cycle modeling framework for urban food systems, 2) monitor water, energy, nutrient, and carbon balances in urban food production, 3) develop physically-based models for hydrologic and biogeochemical dynamics at these sites, and 4) integrate these data and process models into the techno-economic model in order to compare whole-lifecycle energy, water, nutrient, and carbon impacts相对于彼此的替代城市粮食生产策略和常规生产相同的作物。很少有数据可以量化城市粮食生产的水，能源，养分和碳需求以及影响。该项目将产生新的数据，从而实现了三种替代城市粮食生产策略的基于过程和技术经济模型的参数化。该项目将与芝加哥植物园合作通过Windy City Harvest计划（WCH）进行。这项合作将与每年有200名学生（9 - 14年级）和社区成员参与项目科学活动，并能够直接使用项目结果来改善城市粮食生产设施的设计和运营。该项目还将涉及西北大学的学生科学工作，从而每年与大约700名本科生参与，以分析从WCH网站获得的样品中的金属浓度。总体而言，该项目将提供能力，以估算通过在区域尺度上部署城市粮食生产，以及设计这些生产系统并优化其在城市景观中的位置，并让大约2,000名学生和社区成员参与可持续城市粮食生产的分析和开发所需的信息。
