FADN2Footprint
FADN2Footprint is an R package currently under development that estimates the main environmental impacts of farms (climate, biodiversity, water) on the sole basis of their accountancy data (as recorded in the Farm Accountancy Data Network - FADN). It bridges farm-level economic data with environmental performance indicators in a life-cycle assessment spirit.
Input Data
The package supports two versions of FADN: EU level and national FADN paired with the national Land Parcel Information System (LPIS). The latter allows to mobilize spatially explicit open data (e.g. maps of hedges) to refine the estimates.
National FADN + Spatial Data
- National FADN — Detailed farm accountancy data at country level
- National LPIS — Land Parcel Identification System for spatial crop allocation
- National hedges map — Hedge density and landscape structure data
- Cover crop map — Ground cover and inter-crop management data
EU FADN
- EU FADN — Harmonized European-level farm accountancy data, enabling cross-country comparison
Additional Data Sources (embedded in the package to calibrate fixed parameters)
- Farm practices survey & feed tables — Used to derive allocation keys for inputs across activities and products
- Emission parameters — From national Greenhouse Gas Inventories (GHGIs) or IPCC default values for footprint computation
Scope
Adopts an LCA-inspired methodology covering upstream and on-farm processes
Accounts for indirect emissions and impacts along the supply chain (purchased inputs, feed, energy)
