Spatial planning has to be carried out in accordance with the sustainable development principle. When compiling every document indicated in the Spatial Planning and Development Act, local authorities have to take into account the conditions that are valid in a gmina. They should rely on available materials which are a support for the decisions that are made. An element that constitutes support for local authorities is spatial data available in international sources, e.g. the European Environmental Agency or individual sources, e.g. vector versions of the documents in the scope of spatial planning.
The purpose of the article is to present which materials used by local governments can allow for an appropriate assessment of the need for new areas of housing development and the limitation of decisions concerning the liquidation of open areas in cities. The article presents tools and data which constitute a basis for an evidence-based spatial planning policy and have to be used by local authorities. The procedure presented in the article can be a tool supporting the spatial policy and an element of evaluation whether the decisions made by local authorities are correct.
Poland's Village Fund (Fundusz Sołecki) is an instrument operating at the level of the so-called sołectwo, into which local-administration units known as gminas may be further sub-divided. These are therefore auxiliary administrative units in rural areas whose receipt of means from the Fund in question allows for the activation of local communities. Against that background, the research detailed here sought to examine Village Fund by reference to the greenspace-related projects pursued using it in the rural gminas of Łódzkie Voivodeship. Additional aspects are the classification of the tasks carried out, presentation of the statistical analysis applied, and consideration of the breakdown obtained for indicators relating to the share of funds allocated to green areas – by reference to the properties of the normal distribution curve.
The article presents the issues of spatial planning on the case study of Łódź. Of significance in Łódź are its outer peripheries, which due to their natural value have become areas that must be protected and monitored in order to limit the anthropogenic impact. Protection of these areas may be carried out through the usage of instruments such as local land-use plans which help to limit the green field development phenomenon and to look after the biologically active surfaces within the borders of the city. The second step which may concern the areas with local land-use plans, as well as those without current local land-use plans, is monitoring. Such monitoring may be carried out through the analyses of satellite imagery of the city area. Such activities are a kind of low-budget enterprises which bring many benefits at a very small cost resulting from the purchase of satellite imagery. From the perspective of the authorities, a crucial fact is that the material collected during the analyses of the satellite imagery may be used in the initial phase of the planning process as an element of the inventory of areas designated for the development of land-use plans.
The use of geoinformation becomes more and more common due to the implementation of EU law to the regulations of individual member states. The opportunity of faster implementation of spatial information systems and geoinformation is possible thanks to the popularisation of knowledge concerning the ways of using spatial information. The pilot survey was conducted in rural and urban-rural gminas of Zgierz poviat (administrative unit of the 2nd order). The aim of the survey was to check if the officials in small gminas have knowledge and access to geoinformation. A part of the research was the identification of the sources of obtaining knowledge and sources of obtaining spatial data. The consequence of such an attitude was, as well, to prove in which areas of territorial unit activity geoinformation is used. An important element of the study was self-assessment of the knowledge level of the officials about geoinformation and spatial information systems. The study helped to determine if there is a knowledge gap in Polish gminas. The analyses allow for indicating the level and areas of geoinformation usage by the local authorities.
