Abstract:

Following a decision of the European Parliament, the European Statistical Office (EUROSTAT) in close cooperation with the Directorate General responsible for Agriculture and the technical support of the JRC, is organising regular, harmonised surveys across all Member States to gather information on land cover and land use. This survey is known as LUCAS (Land Use/Cover Area frame statistical Survey). The name reflects the methodology used to collect the information. Estimates of the area occupied by different land use or land cover types are computed on the basis of observations taken at more than 250,000 sample points throughout the EU rather than mapping the entire area under investigation. By repeating the survey every few years, changes to land use can be identified.

The LUCAS 2015 Soil Module targeted a revisit to 90% of the locations sampled in the 2009 survey and expanded to cover all 28 EU Member States (MS) and locations at altitudes above 1000 m. The remaining 10% of samples were reassigned to new locations within each MS. Approximately 22,000 samples have been analysed for pH, organic carbon, nutrient concentrations (N, P, K) and electrical conductivity (new in 2015) - over 23 000 samples were analysed if countries outside the EU). Particle size has was only measured for locations that were sampled for the first time in 2015 (otherwise see 2009 data for particle size). An additional 1,000 samples (approximately) were collected and analysed from Albania, Bosnia-Herzegovina, Croatia, North Macedonia, Montenegro, Serbia and Switzerland. Data for these countries will be uploaded in the coming months.
