Mangroves as a Nature-Based Solution and a Tool for Coastal Resilience

  • Prisca Ayassamy

摘要

Mangroves are increasingly recognized as effective Nature-Based Solutions (NBS) for enhancing climate resilience in coastal regions; however, their efficacy and the enabling conditions necessary for successful implementation remain inconsistently documented. This systematic review follows PRISMA guidelines and synthesizes findings from 13 peer-reviewed articles published between 2013 and 2023. Key findings reveal that mangroves mitigate annual flood damages by up to $65 billion globally while also delivering co-benefits such as improved water quality, enhanced fisheries, and increased recreational opportunities. The effectiveness of these interventions is strongly shaped by governance structures, especially adaptive and polycentric frameworks, and financial accessibility, which remains a predominant constraint, particularly in low-income tropical nations. Based on the analysis, four strategic interventions are proposed: (i) leveraging ecotourism to internalize local socio-economic benefits; (ii) framing large-scale mangrove restoration as an NBS to attract climate financing; (iii) creating blue-carbon instruments embedded within adaptive governance systems; and (iv) initiating community-level social resilience programs. This review calls for greater emphasis on multilingual research dissemination, comprehensive economic valuation, and equitable benefit-sharing models to fully realize the potential of mangroves as NBS for climate adaptation.
