EO4SD forest management

Global Biomass

This product supports the quantification of Biomass Change, which can be used to identify degradation and forest loss for REDD+ and other forest monitoring purposes.

By combining a biomass map with a dynamic forest change map, rather than a static forest area map, it is possible to understand the change in biomass over time. Biomass maps can be used to derive emission factor (EF) information resulting from changes in land use (where land use/ land cover information is available) and can be used in reporting for a number of mechanisms. Areas of high carbon stock, and potential emission hotspots (if deforestation were to occur) can also be identified.

The Biomass product can be used as an input for:

  • Assessment of Activity Data for REDD+
  • Sustainable Forest Management (SFM)
  • Forest Landscape Restoration (FLR)
  • Forest management/ planning
  • Mangrove Monitoring
Image and products by ESA’s Climate Change Initiative Biomass Project



A global terrestrial biomass map of 100 m resolution was produced for 2010, 2017 and 2018.

The maps were produced by the ESA’s Climate Change Initiative Biomass Project (more info)


Global, Regional, National, Sub-national

Wall-to-wall global products available for several time periods


Three time periods are currently available: 2010, 2017, and 2018.


Sentinel-1 and ALOS-2 PALSAR-2 data (inputs),
SCANSAR data, ICESAT data and Moderate Resolution Imaging Spectroradiometer (MODIS) Vegetation Continuous Fields (VCF; or MOD444B for map production

Spatial resolution: 100m


Global AGB map tends to over-estimate biomass at low biomass ranges (50-100 Mg ha-1) and under-estimate at high biomass ranges (> 250 Mg Ha-1)

Between 50 and 300 Mg ha-1, mean differences between the map and reference dataset are well within 20% of the map values.

Per pixel error values expressed as standard error are provided.

Positional accuracy needs to be validated at a national level.
