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.

Ukraine is one of the countries where the problem of waste management is particularly acute and deteriorating every year. The Regional Waste Management Plan in Volyn region by 2030 envisages a reduction in the total amount of landfilled waste from 97.68% to 30%, and the number of sites for their disposal – up to 4–8 regional landfills per region. Ecological-economic mechanism of solid non-hazardous waste (SNHW) management is based on a harmonious combination of environmental constraints with the economic attractiveness of regional landfills and involves working with geographically defined objects based on the use of methods of processing geospatial information, one of which is mathematical-cartographic modelling. Thus, the main purpose of this work is to substantiate the possibilities of applying the method of mathematical-cartographic modelling in the design of the system of regional landfills of SNHW in the Volyn region. In order to address the issue of placement of SNHW management facilities, the territory of the region is divided into four management clusters. The division of the territory took into account the composition, properties, methods of solid waste collection, logistics, load on waste processing complexes, volumes of waste generated, spatial planning, etc. Three probable options for the location of regional landfills have been developed for the Lutsk SNHW cluster. The results of the study can be used in the development and adjustment of regional plans, waste management programs, as well as in the work of the executive bodies of the united territorial communities.
