This project will bring together a cross-section of disciplinary experts, community leaders, and policymakers as a research coordination network to address the problems of rising sea-level and salt-water intrusion into coastal regions. Nearly all of the North American Coastal Plain is subject to rising sea levels, land subsidence, more severe hurricanes, and more intense droughts. All four of these trajectories of change are leading to more frequent and higher magnitude inputs of marine salts into coastal plain soils. The penetration of salinity into the coastal interior is exacerbated by groundwater extraction and the high density of agricultural canals and ditches throughout much of the rural landscape. The resulting saltwater intrusion and sea-level rise represent significant challenges for the largely rural landscape and small communities throughout the North American Coastal Plain. Loss of agricultural productivity and rapidly changing habitats in conservation areas may differentially impact disadvantaged rural populations and communities. These environmental justice issues are multi-generational, involving land availability, bank and agency lending practices, and race. The community of scholars and practitioners engaged in research and management of sea-level rise and saltwater intrusion will help develop plans to adapt to this expanding environmental change. The decisions that coastal communities make in response to rapid environmental change will shape the future socioecological trajectory of US coastal plain landscapes.The primary focus of the Saltwater Intrusion and Sea Level Rise (SWISLR) Research Coordinating Network is to build an integrated conceptual scaffolding that will expand the capacity to forecast and prepare for impacts throughout the rural communities of the Atlantic and Gulf coasts of North America. In addition to variable rates of sea-level rise across the outer coastal plain, differences in geomorphic setting, water resources infrastructure and management, and climate extremes are generating very different patterns of saltwater intrusion. Documenting both the absolute magnitude of this rapid environmental change, and the causes and consequences for its spatial and temporal variation, represent an opportunity to construct new mechanistic models that link directional climate change to temporally and spatially dynamic socio-environmental impacts. The diverse effects on various landscapes provide opportunities to examine modern theories of ecosystem state change in systems with exceptionally strong socioecological feedbacks.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.

该项目将汇集各领域的学科专家、社区领袖和政策制定者，作为一个研究协调网络，以解决海平面上升和咸水入侵沿海地区的问题。北美沿海平原几乎所有地区都受到海平面上升、地面下沉、更严重的飓风和更严重的干旱的影响。所有这四种变化轨迹都导致海盐更频繁和更大程度地输入沿海平原土壤。地下水开采以及遍布大部分农村地区的高密度农业运河和沟渠加剧了盐分向沿海内陆的渗透。由此产生的咸水入侵和海平面上升对整个北美沿海平原以农村为主的景观和小社区来说是一个巨大的挑战。农业生产力的丧失和保护区内快速变化的生境可能会对处于不利地位的农村人口和社区产生不同的影响。这些环境正义问题涉及多代人，涉及土地可获得性、银行和机构贷款做法以及种族。从事海平面上升和咸水入侵研究和管理的学者和实践者社区将有助于制定计划，以适应这一不断扩大的环境变化。沿海社区为应对快速环境变化而做出的决定将塑造美国沿海平原景观未来的社会生态轨迹。咸水入侵和海平面上升(SWISLR)研究协调网络的主要重点是建立一个综合的概念脚手架，以扩大预测和准备整个北美大西洋和海湾沿岸农村社区的影响的能力。除了外围沿海平原海平面上升的速度不同外，地貌环境、水资源基础设施和管理以及极端气候的差异正在产生非常不同的咸水入侵模式。记录这一快速环境变化的绝对规模，以及其时空变化的原因和后果，为构建将定向气候变化与时间和空间动态社会环境影响联系起来的新的机械模型提供了机会。对不同景观的不同影响提供了机会，在具有异常强烈的社会生态反馈的系统中检验现代生态系统状态变化理论。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。
