Despite large investments in improving water quality efforts worldwide, cyanobacterial harmful algal blooms (CHABS) remain common and are getting worse. CHABs can produce toxins, which can sicken or kill humans and animals, impair recreational opportunities, and threaten the supply of drinking and irrigation water for millions of people worldwide. Improving water quality and reducing CHABs is vital for society and a healthy environment. Fundamental gaps in knowledge of this complex socio-environmental system (SES) limit our ability to fully understand the problem, assess response actions, and motivate and support transformative change. This DISES award supports research addressing critical knowledge gaps around the role of nutrient pollution in determining the size and toxin concentrations of CHABs, the promotion of farmer collective action, the economic benefits of water quality improvements, and improving SES governance. The investigators will address these gaps through improved watershed simulation and integrated economic and hydrologic modeling, advances in SES science and theory for water quality governance, and improved capacity for transforming SES through actionable knowledge to support CHABs decision making. Results will inform national integrated assessment models of nutrient pollution, and the guidance produced will inform management in other eutrophic waterbodies impacted by agriculture. This research will train the next generation of interdisciplinary SES scholars and practitioners including two postdoctoral scientists and seven graduate and at least eight undergraduate students. The team will involve more than 100 students in outreach. Multiple datasets will be made available on the Open Science Framework, and these will also be used to develop CHABs SES curricula that will benefit teachers and students in grades 5-12. The curricula will be distributed through the Teaching Channel and the daVinci Program. CHABS degrade water quality and diminish essential ecosystem services worldwide. Despite longstanding efforts to understand this complex SES and reduce excess nitrogen and phosphorus inputs, poor water quality remains a persistent problem. Fundamental gaps in knowledge of critical SES components and interactions include: understanding the role of nitrogen (N) loading and N and phosphorus (P) cycling in driving CHAB biomass and toxin concentrations; farmer collective action behavior; the economic benefits of water quality improvement; and how to change SES governance. These gaps inhibit our ability to adjust existing management and governance approaches, which may make toxic CHABs worse. This interdisciplinary research and education project focuses on advancing CHABs SES science, improving practical CHABs management, and training the next generation of SES scholars to help address this societal challenge. Specifically, this research will: 1) advance fundamental understanding of more transformative approaches to behavioral change and SES water quality governance; 2) advance fundamental understanding of the role of N in driving CHAB biomass and toxicity and how in-stream processing of N and P influences the spatial and temporal distribution of water quality improvements; 3) improve watershed and integrated assessment models to incorporate new fundamental understanding of behavioral change, the role of N (in addition to P), in-stream transformation of N and P, and economic benefits of water quality; and 4) employ improved integrated assessment models to assess the effects of different coproduced management and governance scenarios on downstream water quality, coproduce actionable policy-relevant information and knowledge, and test the effectiveness of a stakeholder-engaged approach for building transformative capacity and enabling improved SES water-quality governance. Qualitative and quantitative datasets, insights and guidance, improved models, and curricula will be produced and made widely available through academic and non-academic outlets.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.

尽管全球在改善水质方面投入了大量资金，但蓝藻有害藻华 (CHABS) 仍然很常见，而且日益严重。 CHAB 会产生毒素，使人类和动物患病或死亡，损害娱乐机会，并威胁全世界数百万人的饮用水和灌溉水的供应。改善水质和减少 CHAB 对于社会和健康环境至关重要。对这一复杂的社会环境系统（SES）的认识存在根本性差距，限制了我们充分理解问题、评估应对行动以及激励和支持变革的能力。该 DISES 奖项支持研究解决营养物污染在确定 CHAB 的大小和毒素浓度方面的作用、促进农民集体行动、改善水质的经济效益以及改善 SES 治理方面的关键知识差距。研究人员将通过改进流域模拟和综合经济和水文建模、SES科学和水质治理理论的进步以及通过可操作的知识提高SES转型能力来解决这些差距，以支持CHAB的决策。结果将为国家营养物污染综合评估模型提供信息，所产生的指导将为受农业影响的其他富营养化水体的管理提供信息。这项研究将培养下一代跨学科 SES 学者和实践者，包括两名博士后科学家和七名研究生和至少八名本科生。该团队将有 100 多名学生参与外展活动。开放科学框架将提供多个数据集，这些数据集还将用于开发 CHAB SES 课程，这将使 5-12 年级的教师和学生受益。课程将通过教学频道和达芬奇计划分发。 CHABS 会降低全球水质并减少重要的生态系统服务。尽管长期以来一直努力了解这种复杂的社会经济状况并减少过量的氮和磷输入，但水质不佳仍然是一个长期存在的问题。在关键 SES 组成部分和相互作用方面的基本知识差距包括： 了解氮 (N) 负荷以及氮和磷 (P) 循环在驱动 CHAB 生物量和毒素浓度中的作用；农民集体行动行为；水质改善的经济效益；以及如何改变 SES 治理。这些差距限制了我们调整现有管理和治理方法的能力，这可能会使有毒的 CHAB 变得更糟。这个跨学科研究和教育项目的重点是推进 CHAB SES 科学、改进实用的 CHAB 管理并培训下一代 SES 学者以帮助应对这一社会挑战。具体来说，这项研究将：1）增进对行为改变和SES水质治理更具变革性方法的基本理解； 2) 加深对氮在驱动 CHAB 生物量和毒性方面的作用以及氮和磷的流内处理如何影响水质改善的空间和时间分布的基本了解； 3) 改进流域和综合评估模型，纳入对行为变化、N（除 P 之外）的作用、N 和 P 的河流内转化以及水质经济效益的新基本认识； 4) 采用改进的综合评估模型来评估不同共同制定的管理和治理方案对下游水质的影响，共同制定可操作的政策相关信息和知识，并测试利益相关者参与的方法在建设变革能力和促进改进方面的有效性。 SES水质治理。将制作定性和定量数据集、见解和指导、改进的模型和课程，并通过学术和非学术渠道广泛提供。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和能力进行评估，被认为值得支持。更广泛的影响审查标准。
