In the United States, agricultural runoff is the leading contributor of nutrient pollution in the Upper Mississippi River Basin, causing environmental impacts, including a large hypoxic zone in the Gulf of Mexico (Rabotyagov et al. 2014). In an attempt to decrease these impacts, government agencies and nonprofit organizations invest billions of dollars annually promoting and paying for conservation practices (e.g, Agriculture Improvement Act of 2018 [H.R. 2, 115th Congress, 2018]). Many of the programs through which these funds are administered may miss the mark because they are not tailored for an important and influential stakeholder for redressing the problem—the person who owns the farmland.

租用农田：密西西比河流域上游养分管理难题中缺失的一块？

在美国，农业径流是密西西比河流域上游养分污染的主要原因，造成环境影响，包括墨西哥湾的大面积缺氧区（Rabotyagov 等人，2014 年）。为了减少这些影响，政府机构和非营利组织每年投资数十亿美元来促进和支付保护措施（例如，2018 年农业改进法案 [HR 2, 115th Congress, 2018]）。管理这些资金的许多计划可能没有达到目标，因为它们不是为解决问题的重要和有影响力的利益相关者量身定制的——拥有农田的人。
