The technology utilizes soil agricultural maps and provides information on quality of sealed soils.
It involves cellular automata software to build the model of land use change and produce the forecasts for various soil protection scenarios.
Spatial development of the functional areas. These are mostly areas of soil protection for food production purposes. The delineation is based on land productivity information (present on soil-agricultural maps), distribution of high nature value areas, need for establishment of “green rings” around the bigger cities.
The maps will be sent to the municipal authorities, with a scientific comment on the problem. The technology enables determining the scale of the soil sealing threat in the province, also what is the soil quality class of the area of interest. In the municipalities with the greatest soil sealing problem and with perspective to expand in the future, there is a need for new legal regulations to force soil protection in local spatial plans. The regional spatial planning office should become a coordinator for the local spatial planning offices, to raise the knowledge about how to use soil digital maps in spatial planning, especially in the case of protecting the soil against soil sealing process. For the municipalities, large scale maps are produced, which contain results of soil sealing forecasting model.
Land use maps of at least 10-meter resolution are produced for two historical periods through classification of the satellite images and using available local land use information. The information on land use change is superimposed on maps characterizing soil quality in order to detect to what extend the urbanization took place on valuable soils. The new sealed area, reflecting the built up sprawl of at least last 15 years, consists with expansion of the following land use classes: continuous residential area, commercial/industrial area and transport facilities. The soils under these new land use types fully lost their environmental functions.
In the soil sealing forecasts the Cellular Automata-based Metronamica model is used. The software was developed and provided by the Research Institute from Knowledge Systems (RIKS) from Maastricht, The Netherlands. The software utilizes cellular automata model to spatially distribute areas of particular land use classes with assumption that the neighborhood of a cell (surrounding cells) influences the transition of this cell into other land use class in the next time step. The method utilizes land use maps and soil quality maps.
