Statistical presentation |
Data description | Statistical survey on the land use distribution provides: Total area and share of the area of main land use types aggregated from the information about the land use of the land properties in the cadastral map. The data is presented on national level, by administrative-territorial units and by territorial units for statistics (NUTS). |
Classification system | - Classification of the main land use types:
- Urbanized areas
- Transport areas
- Agricultural areas
- Forest areas
- Areas occupied by water and water bodies
- Protected areas
- Disturbed areas
- Classification of the durable land use of the land properties
- Unified Classification of Administrative-Territorial and Territorial Units (UCATTU)
- Nomenclature of territorial units for statistics (NUTS)
|
Sector coverage | Not Applicable. The survey does not observe any socio-economic sectors. |
Statistical concepts and definitions | The unit of observation is the land property from up-to-date cadastral map, together with the main cadastral data on the durable land use of the land property and the purpose of use of the territory, recorded in the cadastral registers. Land property - part of the territory, including areas permanently covered by water, defined by boundaries in conformity with the right of ownership. Durable land use (specific purpose of use) of the land properties shall be determined by the relevant detailed plan and recorded in the cadastral registers. The classification of the durable land use of the land properties as well the relevant codes are determined in Annex 3 of Regulation No. RD-02-20-5 of 15 December 2016 on the content, creation and maintenance of the cadastral map and cadastral registers, issued by the Minister of the Regional Development and Public Works. The area of the land property shall be assigned to the territory of one of the main classes of land resources (land use types), according to the durable land use of the land property. Main land use types: Urbanized areas include land properties for residential use, for public buildings and complexes, for greened areas and sports facilities, for resort and recreational facilities, for production and storage facilities as well as land properties with special purpose and use. Transport areas include land properties for traffic and transportation facilities and land properties for conduit facilities. Agricultural areas include land properties - crop fields, permanent crops, meadows and pastures. Forest areas include land properties - wood producing and non-wood-producing forest areas. Areas occupied by water and water bodies include land properties for watercourses, water bodies and facilities. Protected areas include land properties for protected natural environment and for cultural heritage sites. In this category, by type of durable land use, fall mainly land properties that are state owned. Disturbed areas include land properties for mineral extraction sites, land properties, occupied by industrial and municipal waste, degraded land. Not classified - This category include all areas without digital cadastral map coverage. It also includes individual land properties from the cadastral map for which there is no value for the durable land use and for the purpose of use of the territory. |
