Urban Sprawl Impact on Farmland Conversion in Suburban Area of Wroclaw, Poland

The developments in suburban areas are changing the peri-urban landscape, by transforming the agricultural land into discontinuous urban fabric. Tracking these changes requires different approaches. The aim of the research is to identify the spatial development of suburban zone with the use of the spatial information-based approach of estimating the location of suburban plots. The authors introduced parameters describing the building plots for single family housing in the suburban areas on the example of the surrounding municipalities of the city of Wrocław, Poland. Landscape metrics tools were used to delineate the suburban plots not identified by Corine Land Cover 2012. The results were verified with the use of the prices and values register for real estates. The results show that there is an increasing pressure on farmland conversion into suburban areas expressed by the number of transactions and the total areas of sold housing plots. The plots that have been purchased for the single-family housing between 2004 and 2016 constitute about 10 % of all existing plots. About 42 % of suburban properties are designed in the distance not exceeding 3 km from the existing settlements; they are, however, not connected by infrastructure with other build-up areas.
