 Mangrove ecosystems are found along tropical and subtropical coastlines around the world and provide a wide range of important services, including coastal erosion control, water filtration, fish and shrimp breeding grounds, and tourism attractions. However, they are among the most threatened and vulnerable ecosystems globally, with a significant decline in population occurring over the past few decades. International efforts, such as the Ramser Convention on Wetlands and the Kyoto Protocol, highlight the need for urgent protection measures and conservation activities to preserve mangrove habitats. Remote sensing has emerged as a powerful tool for providing spatial and temporal information about mangrove ecosystems, including identification, mapping, and monitoring of changes in mangrove populations. This review paper provides a comprehensive overview of the use of remote sensing for mangrove ecosystem mapping and analysis, covering the variety of remote sensing data types and techniques used for data analyses. It also discusses the potential and limitations of remote sensing for mangrove ecosystem research and management.
