摘要

2020年，美国环境保护局缩小了“美国水域”的定义，大大限制了《清洁水法》对湿地的保护。目前的政策辩论集中在湿地效益的不确定性上。我们使用详细的洪水索赔和土地使用数据估算了美国湿地对洪水缓解的价值。我们发现，2001年至2016年间，平均每公顷湿地的损失每年给社会造成1840美元的损失，在发达地区超过8000美元。我们记录了湿地效益的显著空间异质性，这对洪水保险政策和50%的“孤立”湿地面临失去联邦保护的风险有影响。(jel k32, q24, q25, q53, q58)

Wetlands, Flooding, and the Clean Water Act

In 2020 the Environmental Protection Agency narrowed the definition of “waters of the United States,” significantly limiting wetland protection under the Clean Water Act. Current policy debates center on the uncertainty around wetland benefits. We estimate the value of wet-lands for flood mitigation across the United States using detailed flood claims and land use data. We find the average hectare of wetland lost between 2001 and 2016 cost society $1,840 annually, and over $8,000 in developed areas. We document significant spatial heterogeneity in wetland benefits, with implications for flood insurance policy and the 50 percent of “isolated ” wetlands at risk of losing federal protection.
