Abstract
Variations due to climate change like rising sea levels, recurring storm surges and changing wave conditions coupled with unsustainable development along the coast are exacerbating coastal populations' vulnerability to coastal dangers globally. The ecosystem based solution to achieve sustainable development is increasingly advocated in the last two decades to leverage nature's robust adaptive capacity to change and protect people against its negative consequences. Mangroves protect and maintain a rich marine biodiversity in the tropics and subtropics and are crucial carbon sinks. The present study thus analyses mangroves' role as ecosystem-based technique to reduce disaster risk and adapt to climate change using Mauritius, a small island state, as case study, particularly the coastal protective and climate change adaptive capacities of the two local species Rhizophora mucronata Lam. and Bruguiera gymnorrhiza (L.) Lam. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were used to retrieve resources from Google Scholar, Web of Science and ScienceDirect for the 2002 to 2022 period. A total of 41,789 records were identified and through a robust screening and filtering process only 50 studies were deemed relevant to the present study. In this context, key attributes of mangrove forests were found to be in reducing coastal flood risk, sheltering coastal regions during storms and stabilizing the coast. This study lays the foundation to consider Rhizophora and Brugueira as robust nature based solutions for Mauritius which will be of key importance to decision makers, researchers and the public at large to consider restoring degraded mangrove sites and promote ecosystem-based approaches to reduce disaster risk, adapt to climate change, enhance marine spatial planning and better coastal zone management.
气候变化引起的变化,如海平面上升、反复出现的风暴潮和不断变化的海浪条件,加上沿海地区不可持续的发展,加剧了全球沿海人口对沿海危险的脆弱性。在过去二十年中,越来越多的人提倡以生态系统为基础的可持续发展解决方案,利用大自然强大的适应能力来改变和保护人类免受其负面影响。红树林保护和维持了热带和亚热带丰富的海洋生物多样性,是至关重要的碳汇。因此,本研究以小岛屿国家毛里求斯为例,分析了红树林作为基于生态系统的技术在减少灾害风险和适应气候变化方面的作用,特别是两种当地物种Rhizophora mucronata Lam的沿海保护和气候变化适应能力。和木榄(L.)林。使用PRISMA(系统评价和荟萃分析首选报告项目)指南从谷歌Scholar, Web of Science和ScienceDirect检索2002年至2022年期间的资源。总共确定了41,789条记录,通过强有力的筛选和过滤过程,只有50项研究被认为与本研究相关。在此背景下,红树林的关键属性是降低沿海洪水风险,在风暴期间为沿海地区提供庇护和稳定海岸。这项研究为考虑Rhizophora和Brugueira作为毛里求斯强大的基于自然的解决方案奠定了基础,这将对决策者、研究人员和广大公众考虑恢复退化的红树林遗址和促进基于生态系统的方法来减少灾害风险、适应气候变化、加强海洋空间规划和更好的沿海地区管理具有关键意义。
期刊介绍:
The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
