通过选择实验调查,发现密西西比河流域居民愿意为改善当地水质和帮助减少墨西哥湾缺氧问题支付费用,尤其看重减少藻华和改善鱼类种群。

Abstract

Improvements in local surface water quality in the Mississippi River Basin (MRB) can contribute to the regional environmental goals of reducing hypoxia in the Gulf of Mexico. To inform estimates of the benefits of water quality policy, we use a choice experiment survey in a typical subwatershed of the MRB to estimate willingness to pay for local environmental improvements and helping to reduce hypoxia far downstream. We find that residents place large values on reduced local algal blooms, improved local fish populations and diversity, and meeting local commitments to help with the regional environmental problem. <i></i>
