Large-scale CoPe: Reducing Climate Risks with Equitable Nature-based Solutions: Engaging Communities on Reef-Lined Coasts

大规模应对：通过公平的基于自然的解决方案降低气候风险：让珊瑚礁沿岸的社区参与该项目支持美国的国家利益，以减少气候风险，应对环境退化，增强脆弱社区的适应能力，并促进公共和私人投资，预防和减少灾害风险。海岸带为当地社区提供关键服务，但也带来了来自陆地和海洋的重大风险，包括来自海浪、风暴潮、洪水和海平面上升的威胁，所有这些都随着气候变化而增加。保护和恢复沿海生态系统，如珊瑚礁和红树林，有助于减轻这些威胁，同时也支持当地经济和社会复原力。该项目探讨了依赖热带珊瑚礁的社区的风险和利益，在那里，补充珊瑚礁和红树林生态系统已经试行，可以扩大到区域和国家管理水平，称为“基于自然的解决方案”(NBS)。该项目正在与佛罗里达、美属维尔京群岛和伯利兹的沿海社区共同创造新的知识，了解基于生态系统的进程如何帮助应对气候风险并支持公平和适当的国家统计局。该团队在工程、生态和社会科学方面的互补专业知识，将七个学术机构、多个当地合作伙伴和跨区域组织联系在一起，将潜在研究成果的范围扩大到整个美国，并最终扩展到三个重点地区以外的全球热带海岸线。该项目促进了我们对沿海洪水和侵蚀风险以及生态系统和基于自然的解决方案(NBS)的作用的理解，以经验性地评估减灾、社会脆弱性和总体社会环境风险。目标是(1)建立一种包容性的参与性共同设计办法，评估当前和未来的沿海风险，并严格量化国家BS的效益，包括珊瑚礁和红树林的恢复和保护，以公平地降低风险，同时增进人类福祉、经济复苏和生物多样性惠益；(2)确定社区在地点内和地点之间的风险体验有何不同，这如何影响国家BS的执行，以及减缓日益严重的气候变化的适应能力如何与局部影响相关联。这一趋同研究方法通过评估生态系统的社会和经济共同效益，推动了国家统计局减少灾害风险的量化、数据驱动的评估。项目成果支持为国家统计局制定有效的政策变化、社区参与、工程指导、激励和创新融资。这项研究正在使监测和分析方法标准化，以便有效地将积极的沿海可持续性管理解决方案纳入主流。国家统计局的扩大和标准化使用也为扩大不同利益攸关方在气候适应进程中的参与打开了机会。这一奖项反映了国家科学基金会的法定使命，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。

Large-scale CoPe: Reducing Climate Risks with Equitable Nature-based Solutions: Engaging Communities on Reef-Lined CoastsThis project supports US national interests to reduce climate risk, confront environmental degradation, enhance adaptive capacities of vulnerable communities, and advance public and private investment in disaster risk prevention and reduction. Coastal zones provide key services to local communities but also carry significant risks from the land and ocean including threats from waves, storm surges, floods, and sea level rise, all of which are increasing with climate change. Protecting and restoring coastal ecosystems such as coral reefs and mangroves can help mitigate these threats while also supporting local economies and societal resilience. This project explores risks and benefits to communities in tropical coral reef-dependent communities where replenishing coral reef and mangrove ecosystems has been piloted and can be scaled up to regional and national management levels as “Nature-based Solutions” (NBS). This project is co-creating new knowledge with coastal communities in Florida, the US Virgin Islands, and Belize on how ecosystem-based processes can help address climate risk and support equitable and appropriate NBS. The team's complementary expertise in engineering, ecology, and social sciences, linking seven academic institutions, multiple local partners, and cross-regional organizations, expands the scope of potential research outcomes to the entire US and ultimately to global tropical coastlines beyond the three focus regions.This project advances our understanding of coastal flood and erosion risk and the role of ecosystems and “Nature-based Solutions” (NBS) to empirically assess hazards reduction, social vulnerability, and overall socio-environmental risk. The goals are to (1) establish an inclusive participatory co-design approach for assessing current and future coastal risks and rigorously quantifying the benefits of NBS, including coral reef and mangrove restoration and protection, for equitably reducing risks while enhancing human well-being, economic recovery, and biodiversity benefits, and (2) determine how community experiences of risk differ within and across sites, how that affects NBS implementation, and how adaptive capacity to mitigate increasing climate change is related to localized impacts. This convergence research approach advances the quantitative, data-driven evaluation of NBS for hazard risk reduction through the assessment of ecosystem social and economic co-benefits. Project results support the development of effective policy changes, community engagement, engineering guidance, and incentives and innovative financing for NBS. The research is standardizing monitoring and analysis methods to allow for effective mainstreaming of active coastal sustainability management solutions. The expanded and standardized use of NBS also opens the opportunity to broaden participation of diverse stakeholders in the climate adaptation process.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.
