iBIOM-EU Database

The iBIOM-EU Database is a harmonised geospatial database for Europe, developed to serve the integrated modelling work of the Biodiversity and Natural Resources (BNR) programme at IIASA. It brings together land use and management, and other biophysical data on forestry, agriculture, water, and biodiversity, into consistent spatial layers that can be used directly across BNR’s modelling ecosystem, including GLOBIOM, EPIC, G4M, CWatM, and iBIS.

The database is under active development. This page summarises what is currently available, how to access it, and what is on the near-term roadmap.

Status

The iBIOM-EU Database is in active development. Datasets listed under Data Available below have been produced and are accessible to IIASA researchers via the Accelerator. Datasets listed under Future Developments are in progress and will be added to this page as they are released.

Feedback from researchers and modellers using the database is welcome and actively shapes its development.

Data Available

Land Use and Management (LUM)

European land use and management at 100 m resolution for the years 2000, 2010, and 2018. The classification distinguishes management intensity within each broad land use category and covers EU27 plus the United Kingdom.

  • Resolution: 100 m

  • Coordinate system: EPSG:3035 (ETRS89-LAEA Europe)

  • Years: 2000, 2010, 2018

  • Coverage: EU27 + UK

  • Files: ibiom_LUM_europe_100m_[YEAR].tif

See LUM Classification: Full Code List for the full list of LUM classes.

Land Use with Enhanced Wetlands (LUM-EWM)

A version of the LUM layer with wetland classes refined using the European Wetland Map (Tegetmeyer et al., 2025). Approximately 20.7% of wetland pixels are reclassified with more detailed wetland categories. Agricultural and forest pixels are unchanged.

Forest Aboveground Biomass

JRC forest aboveground biomass data redistributed onto the LUM forest mask using NUTS2 statistical balancing. Currently available for the year 2010 only; additional years are planned (see Future Developments).

  • Resolution: 100 m

  • Coordinate system: EPSG:3035

  • Year: 2010

  • Units: Mg/ha

  • Files: ibiom_forest_biomass_2010.tif

Future Developments

The following data products are in active development and will be added to the database as they are released:

Forestry

  • Forest aboveground biomass for additional years beyond 2010

  • Species shares

  • Age class distribution

  • Forest increment data

Crops

Spatial distributions of area and production for 18 European crops: barley, beans, chickpeas, maize, cotton, groundnuts, millet, potatoes, rape seed, rice, soya beans, sorghum, sugar cane, sunflower seed, sweet potatoes, wheat, rye, sugar beet.

Access

The iBIOM-EU Database is hosted on the IIASA Accelerator. Access is currently available to IIASA researchers.

  • Location: IIASA Accelerator

  • Authentication: IIASA credentials required

  • Formats: GeoTIFF (.tif) and Cloud-Optimised GeoTIFF (.cog.tif)

  • Coordinate system: EPSG:3035 (ETRS89-LAEA Europe)

  • Resolution: 100 m
