By uniting literature from farmland preservation, growth management, food systems, economics, bioengineering, and environmental studies, this article provides an overview and valuation of the services that farms provide for urban areas. This article first analyzes the mission statements of 130 nationally accredited land trusts to ascertain the criteria used in preserving farmland. Land trusts present uniform preference for parcels that provide ecosystem services, wildlife habitat, viewsheds, local heritage, and agricultural productivity. The list of benefits provided by land trusts was compared to a literature review drawing from farmland amenity, agritourism, farmland preservation, and ecosystems studies to reveal the range of market values for the various benefits of farmland. The market value of farmland services varies from -$37,541 to 124,000 per acre depending on the method of analysis and location of the farm. This research has strong implications for land-use planning, economic opportunities, and ecosystems infrastructure in peri-urban areas.
通过整合来自农田保护、增长管理、食品系统、经济学、生物工程和环境研究等方面的文献，本文概述并评估了农场为城市地区提供的服务。本文首先分析了130个获得国家认可的土地信托的使命声明，以确定保护农田所采用的标准。土地信托对提供生态系统服务、野生动物栖息地、景观、当地遗产和农业生产力的地块表现出一致的偏好。将土地信托提供的益处清单与从农田便利设施、农业旅游、农田保护和生态系统研究中得出的文献综述进行比较，以揭示农田各种益处的市场价值范围。根据分析方法和农场位置的不同，农田服务的市场价值从每英亩-37,541美元到124,000美元不等。这项研究对城郊地区的土地利用规划、经济机会和生态系统基础设施具有重要意义。
