The aim of the research is to find out the causes of emergence of uninhabited dwelling houses, to state the criteria of their defining and identification, to work out possible solutions for improvement of the situation. The information from the Central Statistical Bureau, the data from the census of 2011 and the information about buildings or slums gathered by the local municipalities have been used in the research. As a result, the classification of uninhabited buildings and recommendations have been worked out.

From a theoretical point of view, the authors have grounded a new paradigm of theoretical planning of land management, which is based on space definition of a complex of factors of rational use of the existing land resources in correlation of interests of subjects-land-users and corresponding land relations in the terms of support of a balanced social-ecologic-economic environment. From a methodological point of view, the authors have proposed a set of methodic approaches as to determination of mechanisms of arrangement of the process of territorial planning in land management according to institutional fundamentals of land relations harmonization at different space levels of management. It is proposed to consider planning of land use as an obligatory and logically inevitable stage of the process of territorial space management that is determined as a primary link, because it specifies aims of the management. It is proved that effective territorial management of land resources and land-use is caused by its territorial planning, which determines the aims of an object development and activity of a managerial subject. A regional link of management should secure the supply of appropriate conditions for living standards of population, effective utilization of territorial resources and development of mutually favorable inter-regional relations. Implementation of efficient regional policy on the basis of market mechanisms requires further improvement of institutional fundamentals.
