Mangrove forests are broadly recognized to support a variety of ecosystem services on coastal margins worldwide. These may significantly contribute the wellbeing millions people, but there is limited information about their importance in Global South. This study mapped for first time flow Brazilian Amazon mangroves, which represent over 700,000 ha mangroves country. We also identified spatial changes across landscapes, including urban, agricultural upland areas and natural protected areas. Our matrix model indicated that waterbodies, sandflats mudflats critical multiple services, provisioning (fish, mariculture), cultural (historical intrinsic value, research, education), regulation (climate, flood control, nursery, breeding grounds).

Conversion mangroves results potential emissions 1228 Mg CO 2 e , 3-fold land use conversion rainforest.

Abstract Mangroves, integral to ecological balance and socioeconomic well-being, are facing a concerning decline worldwide. Remote sensing is essential for monitoring their evolution, yet its effectiveness hindered in developing countries by economic technical constraints. In addressing this issue, paper introduces MANGLEE (Mangrove Mapping Monitoring Tool Google Earth Engine), an accessible, adaptable, multipurpose tool designed address the challenges associated with sustainable mangrove management. Leveraging remote data, machine learning techniques (Random Forest), change detection methods, consists of three independent modules. The first module acquires, processes, calculates indices optical Synthetic Aperture Radar (SAR) enhancing tracking capabilities presence atmospheric interferences. second employs Random Forest classify non-mangrove areas, providing accurate binary maps. third identifies changes between two-time maps, categorizing alterations as losses or gains. To validate MANGLEE’s effectiveness, we conducted case study mangroves Guayas, Ecuador, region historically threatened shrimp farming. Utilizing data from 2018 2022, our findings reveal significant loss over 2900 hectares, 46% occurring legally protected areas. This corresponds rapid expansion Ecuador’s industry, confirming tool’s efficacy despite cloud cover challenges. demonstrates potential valuable monitoring, offering insights conservation, management plans, decision-making processes. Remarkably, it facilitates equal access optimal utilization resources, contributing significantly preservation coastal ecosystems.
