DISES: Valuing and managing engineered ecosystems: Primary and secondary services provided by stormwater ponds in urban landscapes

雨水湿池塘(SWP)在雨水进入湖泊或河流等自然水域之前，会收集从城市和郊区景观流出的雨水。水利工程主要是为了防洪和水质效益，但也可以改善人们的日常生活。例如，SWP可以增加一个社区的娱乐面积和房屋价值。该项目结合了环境、经济和社会研究，以了解人类行为和水源计划的管理如何与水源计划中的自然过程相互作用。这些相互作用影响了排污方案为人类和自然带来的好处。该项目将调查管理如何影响藻类大量繁殖和其他SWP水质问题的权衡。研究人员还将研究人们如何评估SWP，以及评估它们对附近房屋销售价格的影响。该项目将量化水源计划提供的生态系统服务，如改善水质和去除污染物、提高财产价值和增加生物多样性等。生态系统服务的效益和权衡将通过研究不同社会层面(从个人到社区)的社会规范、价值观和决策的差异，以及这些差异如何与生态过程相互作用来记录下来。此外，这项研究将在地方和区域范围内进行，以1)揭示不同社会和治理水平的水资源计划的认知和价值观的差异，2)量化水资源计划提供的生态系统服务(养分去除、保护免受有害藻华滋生、碳封存)，以及3)确定社会对这些服务的偏好。在社会科学领域，经济学家和人类学家将使用调查、焦点小组和享乐主义住房模型的组合来确定SWP对社会的价值。在自然科学领域，生物地球化学家、生态学家和生物学家将对SWP生物地球化学和微生物群落动态的空间和时间方面进行量化。自然科学和社会科学领域将通过地方和全州范围内对SWP及其社区的社会生态调查，测试不同藻类管理方法的有效性的实验，以及使用地理空间方法的综合分析来确定社会人口和SWP生态系统服务之间的关系。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Stormwater wet ponds (SWPs) capture rainwater that runs off urban and suburban landscapes before it enters natural waters like lakes or rivers. SWPs are mainly built for flood control and water quality benefits, but they can also improve people’s daily lives. For example, SWPs can add recreational area and increase home values in a neighborhood. This project combines environmental, economic, and social research to understand how human behaviors and management of SWPs interact with natural processes in SWPs. These interactions influence the benefits that SWPs provide to people and nature. The project will investigate tradeoffs in how management affects algal blooms and other SWP water quality issues. Researchers will also study how people value SWPs and estimate their effect on the sales price of nearby homes. Results will be combined to find ways to increase the ecological, social, and economic value that SWPs provide to people.The project will quantify ecosystem services provided by SWPs such as improved water quality and pollutant removal, enhanced property values, and increased biodiversity. The benefits and tradeoffs in ecosystem services will be documented through research on variations in social norms, values, and decisions across different social levels (from the individual to the community) and how these variations interact with ecological processes. Further, this research will occur at local and regional scales to 1) reveal differences in perceptions and values of SWPs across different levels of society and governance, 2) quantify ecosystem services (nutrient removal, protection from harmful algal blooms, carbon sequestration) provided by SWPs, and 3) establish societal preferences for these services. In the social science realm, economists and anthropologists will use a combination of surveys, focus groups, and hedonic housing models to identify the value of SWPs to society. In the natural science realm, biogeochemists, ecologists, and phycologists will quantify spatial and temporal aspects of SWP biogeochemistry and microbial community dynamics. The natural and social science realms will be linked through local and statewide socioecological surveys of SWPs and their communities, experiments testing efficacies of different algal management approaches, and synthetic analyses using geospatial approaches to identify relationships between social demographics and SWP ecosystem services.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
