Lammert Hilarides and Susanna Tol of Wetlands International, alongside Luz Gil from The Nature Conservancy, have issued a stark warning regarding the accelerating destruction of mangrove forests along the Rakhine coastline in Myanmar. Satellite data from the Global Mangrove Watch (GMW) platform has pinpointed the active clearing of old-growth mangrove stands, a phenomenon that, while often unseen by those on the ground, is starkly visible from space. This alarming trend underscores a pervasive challenge in contemporary mangrove conservation: the difficulty in safeguarding ecosystems that often disappear beyond the reach of routine monitoring and immediate human observation.
The fundamental principle of effective conservation, as highlighted by the GMW initiative, is that "you can’t save what you can’t see." Mangrove ecosystems, critical for coastal resilience, supporting biodiversity, and sustaining livelihoods, frequently vanish in remote areas, far from capital cities and the immediate purview of park managers and local authorities. Governments often lack the sophisticated national systems required to meticulously track changes in these vital habitats. Consequently, decision-makers are frequently compelled to rely on outdated inventories, fragmented field surveys, or anecdotal evidence. This data deficit also hinders financial institutions in their ability to accurately assess their interdependencies and the inherent risks associated with these crucial natural assets. The cumulative effect of this lack of granular, up-to-date data is a predictable recipe for delayed action, misdirected investments, and the forfeiture of invaluable conservation opportunities.
The Transformative Power of Satellite Mapping in Mangrove Conservation
In response to this critical information gap, satellite mapping has emerged as a revolutionary tool for mangrove conservation and restoration efforts worldwide. The Global Mangrove Watch (GMW) platform stands at the forefront of this technological advancement, providing near real-time data on mangrove forests across the globe. This sophisticated platform empowers countries and conservation practitioners to monitor vast and often inaccessible coastlines with unprecedented regularity and consistency. GMW offers free, user-friendly annual maps detailing mangrove extent, loss, and gain for every nation, generated through the advanced analysis of optical and radar satellite imagery.
For policymakers, land managers, researchers, and conservation professionals, access to such reliable mangrove data is transformative. A coastal planner can now conduct detailed comparisons between different districts, identifying areas of urgent need or successful intervention. Community organizations gain the ability to validate their on-the-ground observations with objective, satellite-derived evidence. Crucially, governments can receive near real-time alerts of mangrove loss, enabling rapid response rather than waiting years for outdated reports.
Translating Global Goals into Tangible On-the-Ground Action
Beyond monitoring, GMW plays a pivotal role in enabling countries to integrate mangrove-positive commitments into their national climate, biodiversity, and development agendas. The platform facilitates the translation of these ambitious targets into concrete priorities and investment-ready opportunities at the local level.
The GMW platform is built upon open-source, state-of-the-art scientific methodologies and continuously refined data. This ensures that countries possess the credible baselines essential for tracking progress and reporting on outcomes. The data generated by GMW is instrumental in supporting a wide array of critical initiatives, including greenhouse gas inventories, national wetland assessments, and reporting for major international agreements such as the Paris Agreement, the Kunming-Montreal Global Biodiversity Framework, and the Ramsar Strategic Plan 2025–2034.
By 2026, the Global Mangrove Watch is set to release its fourth revision of mangrove extent and change maps. This iteration promises enhanced accuracy and extends the historical data record back to 1985, providing an unparalleled historical perspective of mangrove dynamics through to 2025. This comprehensive dataset equips coastal managers, project developers, local communities, and financial institutions with the precise, up-to-date information necessary to effectively prioritize, plan, finance, and monitor conservation and restoration activities, even in the most remote locations.
A Unified Foundation for Global Mangrove Protection and Finance
The crucial data provided by GMW forms the bedrock of the Mangrove Breakthrough initiative. This global call to action aims to mobilize $4 billion by 2030 with the overarching goal of securing 15 million hectares of mangroves. This ambitious target is to be achieved through a three-pronged strategy: halting mangrove loss, restoring half of the area that has been lost, and doubling the area of protected mangroves. This initiative is supported by a growing coalition of governments, civil society organizations, research institutions, and financial stakeholders.
Achieving such bold objectives necessitates a credible and actionable plan to translate global ambition into localized impact. This includes identifying precise locations for protection and restoration efforts and clearly articulating the multifaceted benefits derived from these actions. The GMW platform serves as the essential shared baseline and monitoring system for the Mangrove Breakthrough. By providing the most current information on mangrove ecosystems, GMW offers governments, funders, and communities a common understanding of where change is occurring, where interventions are most needed, and whether those interventions are proving effective.
Leveraging GMW’s spatial data, the Mangrove Breakthrough has meticulously calculated regional and national targets for each of its global goals. These detailed breakdowns are accessible through the Regional Readiness reports for Asia, the Americas, and West Africa, complemented by supplementary national summaries for key focus countries. These reports delineate country-specific enabling conditions and strategic priorities for mangrove action. The consistent mapping methodology employed by GMW also fosters transparency, enabling year-on-year progress tracking, facilitating comparisons across different countries and regions, and ensuring clear accountability to funders and local communities.
The Mangrove Breakthrough is thus poised to catalyze a fundamental transformation in how mangroves are protected, restored, and financed. It achieves this by integrating cutting-edge scientific data, practical implementation guidance—such as best practices for successful mangrove restoration—robust financial mobilization strategies, and a framework for sustained global collaboration.
Bridging the Gap: From Mangrove Mapping to Restoration Finance
Further amplifying the impact of GMW’s data, the Mangrove Breakthrough has partnered with Restor, a leading platform for mapping and monitoring nature-based projects worldwide. This collaboration is already cataloging hundreds of mangrove projects and their demonstrable impacts. By consolidating critical information on biodiversity outcomes, innovative financing approaches, and viable business models, the platform aims to elevate high-quality mangrove conservation and restoration opportunities to potential funders and investors. This crucial step helps to bridge the persistent gap between well-conceived mangrove initiatives and accessible financial resources. Moreover, it equips fund managers with the tools to identify credible projects and to accurately assess the environmental impact of their investment portfolios, fostering a more informed and effective flow of capital towards mangrove conservation.

The Global Mangrove Watch (GMW) initiative traces its origins back to 2011, established under the auspices of the Japan Aerospace Exploration Agency’s (JAXA) Kyoto & Carbon Initiative. Its foundational objective was to provide open-access geospatial information regarding mangrove extent and changes to the Ramsar Convention on Wetlands. Today, a collaborative effort involving The Nature Conservancy, Wetlands International, Aberystwyth University, and soloEO continues to host and develop the GMW Platform, dedicated to supporting the critical mission of mangrove conservation and restoration worldwide.
