In Poland there are no uniform regulations and legal norms establishing the principles of space assessment aimed at determining the demand for land consolidation works. The article is an attempt to answer the following question: what factors are important today in determining the demand for this kind of works? The factors were set on the basis of professional literature and on a questionnaire conducted on a group of specialists in land consolidation and on farmers. The aim of the questionnaire was to examine the preferences of chosen land fragmentation factors. The survey was carried out in the Pasym commune, situated in the Warmia and Mazury Voivodeship. The results of the research show that the land fragmentation mostly depends on the number of land plots (parcels) in a farm, their distance to a settlement and the size of a land plot. The least significant factors in this respect proved: a size of a farm and its irregular shape. The research has confirmed a general tendency in spatial changes of small farms in the Warmia and Mazury Voivodeship.
