FEW Workshop: "Scaling Up" Urban Agriculture to Mitigate Food-Energy-Water Impacts; October 5-6, 2015; University of Michigan, Ann Arbor, MI

随着世界上大多数人口现在生活在城市环境中，城市已经成为全球食物-能源-水(很少)循环的主要驱动力。全球化进程通过包括食物、能源、水、材料和资本交换在内的系统互动，将遥远地理位置的城市相互交织在一起。通过食物消费，城市和腹地变得高度相互联系和相互依存。越来越多的人意识到与这种粮食生产-消费关系相关的各种影响，引发了城市农业复兴。PIS建议举办一个跨学科的城市少数研讨会，以了解扩大城市农业规模在以下方面的潜在后果：1)粮食供应和安全；2)水质和再利用；3)能源使用；4)生态系统健康；以及5)公平和治理。在研讨会之前，五个工作组将就知识状况、实施水平以及与其他几个系统的互动情况编写摘要。第六个工作组将评估跨学科城市新陈代谢建模框架的潜力，以评估城市少数系统的相互作用。这些总结将在研讨会上介绍，与会者将在研讨会上进一步描述扩大规模的好处、挑战和过渡途径。为了揭示物理、社会、经济和生态系统之间的联系，项目团队和研讨会参与者包括地理学家、工程师、生态学家、生物学家、地球系统分析员、复杂性模型师、规划师、计算机科学家、公共卫生政策专家等。重点将放在确定能够实现都市农业系统转型的临界点上。研讨会的成果包括一份白皮书和一篇期刊文章，这两篇文章都将确定城市食物-能源-水系统转型所需的基础研究，使它们更加综合、可持续、有弹性和公平。很少有关于都市农业的学术相对发达，但在很大程度上是作为学科界限的研究流存在的。因此，很少有城市系统相互作用被很好地理解。扩大城市农业规模将以非常复杂的方式显著重塑城市消费边界内外的食品、能源和水资源流动，达到更远的生产地理位置。一个基于城市新陈代谢理论的综合、整体的概念框架将使涉及这一挑战的多个学科能够评估扩大规模的潜力，确定影响系统性能的因素，并将复杂、动态的城乡互动联系起来。私人投资机构设想通过气候变化缓解和适应、资源非物质化和本地化等不断变化的条件情景来应用这一适应框架。利用城市新陈代谢框架，研讨会将产生一套明确的研究需求，如果得到解决，将塑造城市农业的未来，并增强城市的可持续性和复原力。

Globalization processes have intertwined cities with distant geographies through system interactions that include the exchange of food, energy, water, materials, and capital. Through food consumption, city and hinterland have become highly interconnected and interdependent. Growing awareness of the myriad impacts associated with this food production-consumption nexus has sparked an urban agricultural renaissance.The PIs propose an interdisciplinary urban FEW workshop to understand the potential ramifications of scaling-up urban agriculture on: 1) food supply and security; 2) water quality and re-use; 3) energy use; 4) ecosystem health; and, 5) equity and governance. Prior to the workshop, five working groups will prepare summaries regarding the state of knowledge, level of implementation, and interactions with other FEW systems. A sixth working group will evaluate the potential of an interdisciplinary urban metabolism modeling framework to assess urban FEW system interactions. These summaries will be presented at the workshop, where participants will further delineate scaling-up benefits, challenges, and transition pathways. To uncover linkages between physical, social, economic, and ecological systems, the project team and workshop participants include geographers, engineers, ecologists, biologists, earth systems analysts, complexity modelers, planners, computer scientists, public health policy experts, and others. Emphasis will be on identifying tipping points that can enable urban agricultural system transitions. Outputs from the workshop include a white paper and journal article, both of which will identify the fundamental research necessary for transitioning urban food-energy-water systems so that they are more integrated, sustainable, resilient, and equitable. FEW scholarship on urban agriculture is relatively well-developed but exists as largely disciplinary-bound research streams. Consequently, urban FEW system interactions are not well understood. Scaling-up urban agriculture will significantly reshape food, energy, and water flows both within the urban consumption boundary and beyond to more distal production geographies in highly complex ways. An integrative, holistic conceptual framework based on urban metabolism theory will enable the multiple disciplines involved with this challenge to evaluate the potential for scaling-up, identify factors that affect system performance, and contextualize complex, dynamic urban-rural FEW interactions. The PIs envision applying this adaptive framework through scenarios of changing condition, such as climate change mitigation and adaptation, resource dematerialization, and localization. Using an urban metabolism framework, the workshop will produce an articulated set of research needs that, if addressed, will shape the future of urban agriculture and enhance the sustainability and resilience of cities.
