About

Wetlands play a fundamental role in climate change mitigation, and provide essential ecosystem services. Yet there is still a lot we don’t know about their precise distribution, extent and inter-annual variability around the world, particularly in the tropics.

The Global Wetlands Map is an initiative to collect and share information on tropical wetlands in a visual format. Users can access data and contribute their own, using standard geographic information systems software such as ArcGIS.

Explore the interactive web-based map, to contribute and verify data, or download the datasets to conduct your own analysis.

The Global Wetlands Map is produced by the Sustainable Wetlands Adaptation and Mitigation Program (SWAMP), a collaborative effort between the Center for International Forestry Research (CIFOR) and the United States Forest Service, supported by the United States Agency for International Development (USAID) and the CGIAR Research Program on Forests, Trees and Agroforestry (FTA).

Data description:

This dataset shows a distribution of wetland that covers the tropics and sub tropics (38° N to 56° S; 161° E to 117° W), excluding small islands. It was mapped in 236 meters spatial resolution by combining a hydrological model and annual time series of satellite-derived estimates of soil moisture to represent water flow and surface wetness that are then combined with geomorphological data. The dataset consist of 6 classes that covers: Fen, Bog-ombrotrophic peat domes, Riverine, Mangrove, Flood-out, Floodplain, Swamp and Marsh.

Data description:

This dataset shows global distribution of histosols (a soil consisting primarily of organic materials) that covers the tropics and sub tropics (38° N to 56° S; 161° E to 117° W), excluding small islands. It was mapped in 236 meters spatial resolution by combining a hydrological model and annual time series of satellite-derived estimates of soil moisture to represent water flow and surface wetness that are then combined with geomorphological data. Methodologically, histosols are identified using the same method than wetlands but with an important alteration: the surface has to be continuously wet (e.g. minimum wet conditions forced to be positive (pTWImin > 0) and the wettest annual conditions are forced to be above a certain threshold (pTWImax > 500) (Gumbricht 2015). Our model identifies areas with hydrological potential for histosol formation, without considerations on activities in the land that might remove this organic matter (e.g. drainage, fires, etc).

Data description:

Forest carbon database system (ForestCDB) is part of the effort to support initiatives such as greenhouse gas inventories, the development of forest reference emission level, monitoring, reporting and verification. ForestCDB invites its visitors, especially those who maintain forest inventory data, manage permanent sample plots or conduct research on carbon stocks, to participate in this initiative. ForestCDB accommodates carbon stocks in five carbon pools: above- and belowground biomass, woody debris and litter, understorey and soil. As a Meta Database, it also provides general information related to the site, such as geographic location, land cover or forest type, and climate and soil.
