In this Technical Brief NIVA describes the research done and showing examples on the Farm Registry. A Farm Registry is a registry of an administrative, public and informative nature that centralizes and unifies agricultural information and allows the (public) administration and the farmers to query all the data about farms and their agricultural parcels and to facilitate administrative procedures. NIVA has investigated the requirements coming from recent European Union Directives and other initiatives and based on these common requirements, the NIVA project has developed a common Farm Registry data model applicable in all EU Member States. This common data model is a good starting point that will enable common outputs, such as common indicators or harmonized data publication. These common outputs may be helpful for farmers, for Paying Agencies or for anyone having interest in agriculture data.
