However, human-induced climate change coupled with other anthropogenic pressures have substantially reduced seagrass distributions, making them one of the most threatened ecosystems on Earth. The challenges associated with seagrass conservation include substantial data gaps and limited low-cost, near-real monitoring methods. To address these challenges, we used 507 Sentinel-2 satellite images, filtered between August 2020 and May 2021, in the Google Earth Engine cloud computing environment for regional scale seascape habitat mapping in north-eastern Brazil, a region where conservation efforts are particularly hampered by data limitations. We mapped 9452 km<sup>2</sup> of coastline up to a depth of 10 m. We identified 328 km<sup>2</sup> of seagrass ecosystems, providing vital open access positional information for a variety of research applications. We also assessed the capability of Sentinel-2 in monitoring temporal changes in coastal habitats, and revealed up to 15.9% declines in seagrass meadow coverage in specific areas over a five-year period in north-eastern Brazil. Our results demonstrate that Sentinel-2 is an effective tool in mapping seagrass distributions at a regional scale. The resulting maps are critical for supporting the conservation of Neotropical coastal biota, including the endangered Antillean Manatee. Our study emphasises the importance of replicable and systematic monitoring methods in the race to conserve threatened coastal ecosystems globally.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This underscores the formidable task of precisely defining and quantifying sustainability within these community contexts. Based on the “You can't manage what you can't measure” adage, this study developed dual frameworks at community scale to assess and enhance the water supply system's sustainability. The assessment framework includes dimensions, indicators, and variables that convene into a Water Sustainability Index (WSI). WSI ranges from 1 to 4 where a score below 1.5 indicates poor water sustainability, while a score exceeding 3.5 signifies excellent sustainability. Likewise, the enhancement framework consists of dimensions, goals, and strategies. These frameworks relied on three specific dimensions, efficiency, resiliency, and community support. The identification of indicators, variables, and goals was based on SMART criteria. While the dimensions, indicators and goals are to remain consistent regardless of study areas, variables and strategies are site-specific and their selection needs to be based on each community's situations and data availability. The assessment framework suggested that the Asian Institute of Technology (AIT) community has achieved fair water sustainability status with a score of 2.25. The strategic framework yielded several recommendations aimed at enhancing the sustainability of the water supply system at the AIT. The study's outcomes offer tools to evaluate the current situation of sustainability and assists local community authorities in devising solutions to enhance sustainability in community supply systems.

Cultivation of the PP-W system under IOM registered the highest energy use efficiency (73.24). Concerning the eco-efficiency index (EEI), cultivation of PP-W under the IOM production scenario registered ∼ 2.85 times higher EEI (0.20 US$ MJ<sup>−1</sup>) over the M-Mus cropping under CS. Thus, findings inferred that legume-embedded systems under either IOM or ICM production scenarios are sustainable production models for fetching higher profitability with minimum environmental impact under semi-arid regions.</p></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266597272400148X/pdfft?md5=92e2d35c55606818ee2bc40b2e538c12&pid=1-s2.0-S266597272400148X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142272957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
