High nature value (HNV) farmland

The concept of High Nature Value (HNV) farmland describes the link between extensive farming systems and their use of semi-natural land and the conservation of high biodiversity in agricultural landscapes. The HNV farmland data set supports analysis of the distribution and extent of farmland that holds a special biodiversity value and enables an analysis of spatial patterns and time trends. The data set presented here shows a 2017 update of the time series for the years 2000 and 2012 on the basis of the Corine Land Cover (CLC) accounting layers 2000 and 2012. This recalculation of the HNV farmland time series based on the CLC accounting layers ensures full coherence of the data points and enables a correct calculation of changes between HNV 2000 and HNV 2012. Please note that the JRC/EEA HNV farmland methodology is currently being revised and an updated time series for the years 2000 to 2018 will be published by the end of 2022.
