Land use and land use change have a significant impact on national greenhouse gas (GHG) emissions and are therefore an integral part of national GHG reporting. The Land Parcel Identification System (LPIS) is a high-resolution agricultural database that was developed to assist farmers and authorities with applications for agricultural subsidies as part of the European Union Common Agricultural Policy. The system is based on agricultural parcels (a single crop type on a single farm), providing a high spatial and temporal resolution land use database.  This high spatial and temporal accuracy allow for a much better understanding of Irish agricultural processes at local and macro scales, and the potential of the Land Parcel Identification System to be used in conjunction with ancillary data allows for a much better assessment of local conditions of specific land use types.
