Water management in south Florida is characterized by the need to balance multiple objectives. Among the objectives are the maintenance of high groundwater levels to limit seawater intrusion and flood control measures that are also used to mitigate dry-season water shortages. In addition, south Florida's current population of 6 million is projected to grow to 10 million over the next 20 years, and urban water demand must be reliably managed. In this exceptionally vulnerable region, sea level rise and salt water intrusion have already impacted drinking water supplies and threaten the integrity of low-lying and highly-valued built and natural environments as diverse as Miami Beach and the Everglades. Long-term adaptive strategies are needed to ensure sustainable water resources for expanding populations, agriculture, and wetlands that serve multiple functions, including support of Florida's fishing industry. Development of such strategies has been hampered by conflicting stakeholder interests and technical, economic, and political challenges. This project will conduct highly interdisciplinary research, utilizing the expertise of multiple institutions, to investigate the hydrologic, economic, ecologic, and human behavioral dimensions of sustainable water management and land use planning under various climate change, economic, population, and sea level rise scenarios. The research will employ hydro-economic optimization approaches based on robust decision making to develop management strategies that ensure the resilience of water supplies for the built and natural systems, while also accounting for the broad-sector value of water use. Optimization criteria will incorporate the results of project research linking water management, ecological function, and the economic value of ecosystem services. New experimental approaches will be implemented to better understand the impacts of scenario information type and uncertainty on both selection of decision criteria and evaluation of model predictions among individuals and groups of local stakeholders. These experiments are designed to improve understanding of the roles of cognitive and perceptual biases in decision-making when stakeholders examine hydro-economic projections coupled with scenario forecasts. Comparative behavioral analyses of stakeholder evaluations and institutional decision-making will provide unique insights into how information type, information content, and cognitive biases combine to influence risk perception, and how the perceived risks to individual and collective well-being influence scenario selection. Finally, with agency and stakeholder involvement, the project will collaboratively develop recommendations for adaptive water management plans that foster long-term support from the stakeholders. Low-lying coastal regions subject to sea level rise, climate change, and diverse water demands, including growing populations, will benefit from the development of innovative, pragmatic approaches to optimizing the social-ecological benefits of water resources allocation. The research will include novel approaches for dynamically incorporating economics into stakeholder evaluations of adaptive land use and water management strategies. Local, state, and federal agencies responsible for managing south Florida's water resources will benefit from analyses of adaptive schemes that explicitly incorporate uncertainty estimates of potential outcomes. The multiple societies that exist in south Florida, whose options for managing public water resources are limited by climatic, physical, and/or legal constraints, require this type of integrated assessment to promote cooperative decision-making while preparing for uncertain hydro-climatic conditions and socioeconomic futures.

南佛罗里达州的水管理的特征是需要平衡多个目标。目标包括维持高地下水水平以限制海水入侵和防洪措施，这些措施也用于减轻干季水短缺。此外，南佛罗里达州目前的600万人口预计将在未来20年内增长到1000万，并且必须可靠地管理城市用水。在这个异常脆弱的地区，海平面上升和盐水入侵已经影响饮用水，并威胁着与迈阿密海滩和Everglades一样多样化的低洼和高价值建筑和自然环境的完整性。需要长期的自适应策略，以确保可持续的水资源以扩大人口，农业和湿地，这些人口具有多种功能，包括支持佛罗里达捕鱼行业。利益相关者利益以及技术，经济和政治挑战的冲突，这种战略的制定受到了阻碍。该项目将利用多个机构的专业知识进行高度的跨学科研究，以调查可持续水管理的水文，经济，生态和人类行为维度，以及在各种气候变化，经济，人口和海平面上升的情况下的土地利用计划。该研究将采用基于强大的决策制定的水力经济优化方法来制定管理策略，以确保水供应对建筑物和自然系统的供应的弹性，同时还考虑了用水的广大价值。优化标准将纳入将水管理，生态功能和生态系统服务的经济价值联系起来的项目研究结果。将实施新的实验方法，以更好地了解场景信息类型的影响和不确定性对选择决策标准的选择以及对当地利益相关者的个人和群体的模型预测的评估。这些实验旨在提高对认知和感知性偏见在决策中的作用的理解，当利益相关者检查水力经济投影以及场景预测的结合。利益相关者评估和机构决策的比较行为分析将提供有关信息类型，信息内容和认知偏见如何结合影响风险感知的独特见解，以及对个人和集体福祉的风险如何影响场景选择。最后，随着代理商和利益相关者的参与，该项目将协作为自适应水管理计划提供建议，以促进利益相关者的长期支持。在海平面上升，气候变化和多样化的水需求（包括日益增长的人群）中，低洼的沿海地区将受益于创新的，务实的方法来优化水资源分配的社会生态益处。该研究将包括将经济学动态融入自适应土地使用和水管理策略的新方法。负责管理南佛罗里达州水资源的地方，州和联邦机构将受益于对明确纳入潜在结果的不确定性估计的自适应方案的分析。南佛罗里达州存在的多个社会，其管理公共水资源的选择受到气候，物理和/或法律约束的限制，需要这种类型的综合评估，以促进合作决策，同时为不确定的水性气候条件和社会经济期货做准备。
