The health of many marine, coastal, freshwater, and other aquatic ecosystems is inextricably linked to decisions about the management of water quality and quantity. In this article we review the economic literature aimed at quantifying the impacts of water resource management on aquatic species in the United States and the potential welfare gains of managing water and aquatic species systems jointly. Existing studies consider multiple water uses, such as agricultural irrigation and hydropower generation, as well as different societal benefits from aquatic species, such as commercial and recreational fishing and endangered species preservation. These studies use a variety of methodologies, including stated and revealed preference techniques, bioeconomic modeling, and reduced-form econometrics. We conclude with a discussion of future directions for research that could increase understanding of the trade-offs between water and aquatic species management outcomes and identify gains from the joint management of water resources and aquatic species in the United States.

美国水资源和水生物种联合管理的经济学

许多海洋，沿海，淡水和其他水生生态系统的健康与水质和水量管理的决定密不可分。在本文中，我们回顾了旨在量化水资源管理对美国水生生物的影响以及共同管理水和水生生物系统的潜在福利收益的经济文献。现有研究考虑了多种用水，例如农业灌溉和水力发电，以及水生物种的不同社会收益，例如商业和休闲捕鱼以及濒危物种的保护。这些研究使用多种方法，包括明确和揭示的偏好技术，生物经济模型以及简化形式的计量经济学。
