One of the most pressing issues related to soil preservation is its loss due to urbanization and industrialization. The ongoing conversion of land for industrial, residential, and transport infrastructure poses significant threats to the environment and society, which are often not properly recognized or evaluated. This study analyses the progression of this phenomenon at three spatial scales: national, regional (the Lower Silesian Voivodeship), and local (the municipality of Kobierzyce near Wrocław). The latter was selected as a model research area due to its exceptionally high proportion of high-quality arable soils (soil classes I–III) and intense human-induced pressure. The national and regional analyses were based on data from the Agricultural Statistical Yearbooks (2014–2023), while the local analysis drew on exclusion decisions issued between 2004 and 2015, as well as cadastral data from the Land and Building Register. The extent of land conversion was examined according to soil quality classes and the intended use of each excluded plot of land. The results show that, at the national level, exclusions from agricultural use are roughly proportional to the distribution of soil classes. However, in the Lower Silesian Voivodeship, high-quality soils are disproportionately affected. In the Kobierzyce municipality, the data revealed that between 2000 and 2015, 97.9% of agricultural land exclusions involved soil classes I–III, with the majority being black earths from the Wrocław region. The authors advocate substantial amendments to the Soil Protection Act to enhance its effectiveness in safeguarding valuable soil resources. Furthermore, they demonstrate that allocating development projects to high-quality soils is economically unjustifiable and socially irresponsible in the long term.
