We are pleased to announce a major update of the Harmonized IACS Database (v1.3), now publicly available via Zenodo. Now covering 20 countries, we invite researchers, policymakers, and data users to explore the new release and provide feedback. This release significantly expands our existing database, with a full list of upgrades listed below:
New regions covered:
- Baden-Wuerttemberg with data from 2022 (crop info)
- Bulgaria with data from 2014-2025 (crop info)
- Tuscany, Italy with data from 2016-2023 (crop info, farm ids)
- Wallonia, Belgium with data from 2015-2023 (only crop info)
Time series extended:
- Austria (+2025)
- Flanders, Belgium (+2025)
- Czechia (+2024, 2025)
- Denmark (+2025)
- Estonia (+2024)
- Finland (+2024, 2025)
- France (+2024)
- Germany-Brandenburg (+2025)
- Germany-Lower-Saxony (+2025)
- Germany-North-Rhine-Westphalia (+2025)
- Ireland (+2024)
- Lithuania (+2025 LPIS data)
- Netherlands (+2025)
- Portugal (+2025)
- Slovakia (+2024, 2025)
- Slovenia (+2024, 2025)
- Sweden (+2024)
Classification refinements:
- Mixed classes were introduced in the classification scheme to differentiate between pure classes and mixed classes, e.g. cereal-legume mixes, crops with undersowing, pastures with trees etc.
- Missing crop and land-use classes, such as agroforestry, landscape elements, sugar cane and many others were newly added to capture as many as possible different land-uses
- Existing classes were refined by adding more subclasses, such as greenhouses (to differentiate between different crops) and potatoes (to differentiate between growing seasons)
Corrections of translation and classification errors:
- Using LLMs we checked all crop name translations and the classification into HCAT classes and corrected where necessary
Corrections of geodata:
- Removed features with no geometry
- Removed duplicate features
- Made sure all crops of field blocks were reported (concerns Ireland)
- Made field-IDs truly unique
