农业径流是五大湖非点源污染的主要来源,对水质造成有害影响。从莫米河流域进入伊利湖流域西部的养分径流,尤其是磷,导致了频繁而严重的水质危机,包括有害藻华 (HAB)、伊利湖缺氧和 2014 年托莱多水危机(伊利湖 LaMP,2011 年;Scavia 等,2014 年;Stumpf 等,2012 年)。为解决这些日益严重的问题,美国和加拿大共同签署了《五大湖水质协议》(GLWQA),该协议规定了在 2008 年负荷水平的基础上将进入伊利湖受影响区域的总磷 (TP) 和溶解性活性磷 (DRP) 降低 40% 的目标。在本文中,我们通过量化统一的和有针对性的成本分担政策对最佳管理实践 (BMP) 采用的影响以及由此带来的水质变化,计算出成本分担计划成本与伊利湖磷减排之间的折衷前沿。之前使用水土评估工具(SWAT)水文模型的多种变体进行的分析发现,地表下施肥是减少磷径流最成功的途径之一(Scavia 等人,2017 年)。因此,我们特别关注采用地下施肥的付费政策的成本效益及其对减少 P 的影响。

期刊介绍: The American Journal of Agricultural Economics provides a forum for creative and scholarly work on the economics of agriculture and food, natural resources and the environment, and rural and community development throughout the world. Papers should relate to one of these areas, should have a problem orientation, and should demonstrate originality and innovation in analysis, methods, or application. Analyses of problems pertinent to research, extension, and teaching are equally encouraged, as is interdisciplinary research with a significant economic component. Review articles that offer a comprehensive and insightful survey of a relevant subject, consistent with the scope of the Journal as discussed above, will also be considered. All articles published, regardless of their nature, will be held to the same set of scholarly standards.
