According to the regionalisation procedure based upon OECD and EUROSTAT typologies, the land of EU Member States is subdivided into rural areas (ca. 90 per cent of the total EU territory) and urban areas (ca. 10 per cent thereof), generally based on the criterion of population density, with a threshold of 150 (OECD) or 300 (EUROSTAT) inhabitants per square kilometre. The proposed modification of both typologies relies on distinguishing, on the local level, of the third type of areas, called “natural areas,” and characterized as follows: • zero density of population; • occurrence of dense areas with habitats of natural type (forests, lakes, mountains, swamps etc.) within the given area; combined with; • low (negligible) level of human intervention. Desirability of distinguishing between the “natural area” type as opposed to the “rural area” type results from: • its functionality, which is wholly different from that of other types of “rural areas”; • high share of such land in the total area of the EU (more than 40 per cent); • the fact that the share of such areas in current type of rural areas – estimated as ca. 40 to 50 per cent – varies between the member states, from ca. 10 per cent (Benelux, Ireland) up to 80 and more per cent (Finland, Sweden), with less than 40 per cent share in Poland; • possibility to obtain a better approximation of the actual condition, reflected in quality data, including spatial data, describing the environment of natural areas and the remaining rural areas. As a consequence of distinguishing the “natural areas” on local level, we would be able to classify a region/sub-region type of “MOSTLY NATURAL” at regional level, with the share of “natural areas” on a threshold, e.g. 80 or 85 per cent, but no less than two thirds. Implementation of the aforementioned modification of methodology in both types is simple, and it could be performed fast. This is because all of the EU Member States (including Poland) al- ready possess the necessary data in the framework of their IT systems including spatial data sys- tems such as GIS (Geographic Information Systems) included, inter alia, in the IACS (Integrated Administration and Control System), which is mandatory for all the EU Member States for the implementation of the Common Agricultural Policy; as well as other relevant ortho-photos and airborne imagery.

Skorupka122 GLL No. 1 • 2017 Moreover, each of the EU Member States possesses, in digital form, a “cadastre” or an equivalent thereof (such as the “records of land and buildings” in Poland) as well as a system of the State’s administrative division (TERYT in Poland) down to the level of a village/town/settlement. Furthermore, the proposed modification for both typologies is not contrary to the provisions of the existing EU’s and Poland’s regulations on regionalisation.
