Under the Conservation Reserve Program (CRP), a provision of the Food Security Act of 1985, the federal government pays more than a billion dollars annually to landowners who have agreed to retire more than 25 million acres of cropland. Little is known, however, about the efficiency or equity of this program or its role in shaping land use in America. Using a geographical perspective, this project will involve the use of map-based documentary evidence and intensive fieldwork, including interviews conducted in 16 study areas. It will integrate data from disparate elements of the discipline of geography, including detailed information on the subtle gradients in agricultural land use and practices, micro-spatial patterns of soil productivity and erodibility within individual landholdings, and the influence of regional perceptions on landowners as they respond to changing economic and political conditions. The primary focus of this project is at the heart of geography, that is, the recording of patterns of land use and the subsequent identification of factors that help explain those patterns. Such an analysis in this context has the potential to lead to the development of new theory encompassing long-run dynamic effects of how farmers act in anticipation of government policies.

根据1985年《食品安全法》的一项条款--保护储备计划(CRP)，联邦政府每年向同意退耕2500万英亩农田的土地所有者支付超过10亿美元。然而，关于这一计划的效率或公平性，以及它在塑造美国土地使用方面的作用，人们知之甚少。从地理角度来看，该项目将使用基于地图的文件证据和密集的实地工作，包括在16个研究地区进行访谈。它将综合地理学科不同要素的数据，包括关于农业土地利用和做法的微妙梯度的详细信息、个别土地所有权内土壤生产力和可蚀性的微观空间模式以及区域观念对土地所有者应对不断变化的经济和政治条件的影响。该项目的主要重点是地理学的核心，即记录土地利用模式，并随后确定有助于解释这些模式的因素。在这一背景下的这种分析有可能导致新理论的发展，该理论涵盖农民如何在预期政府政策时采取行动的长期动态影响。
