The article examines the formation features of the demographic and economic space in the Saratov region during the first half of the Soviet period (1917–1960). The spatial and temporal vectors of development and their determining factors are analised.

The problem of delimiting agglomerations is an integral part of the broader issue of economic zoning in the socio-economic space. Given its significance for development, it is important to make a methodology for identifying the influence zone of agglomerations as a specific area in spatial planning. To address this issue, this paper proposes a methodology for determining the territorial accessibility of cities based on population size, which combines the use of open data from Open Street Map, modern geospatial techniques, and visualization tools.

Introduction. Transformation is understood as a change in the properties of an air mass: its temperature, humidity, and stability. Transformation changes are especially strong in the summer when cold air from the Arctic basin shifts to the continental regions of Eurasia. When empirically studying the transformation process, there are difficulties associated with determining its beginning and end.

The article considers the influence of knowledge spillovers as a factor of innovative development on the efficiency and intensity of agricultural production in the regions of Russia. The territorial distribution of agricultural patents and references to them in the regions of the country was analyzed, which is one of the methods for identifying knowledge spillovers. Based on this, a typology of Russian regions was carried out on innovative functions of agriculture and the level of creativity.

Introduction. This study focuses on the examination of territorial barriers in urban environments. It analyses the main types of barriers, their role in the spatial development of the city, and their impact on the formation of socio-economic interactions. Data and Methods. A methodology for calculating the permeability coefficient of territorial barriers has been developed.

The issue of regional development in relation to the reproduction of human capital is becoming increasingly urgent every year. Therefore, it is necessary to analyze the potential for redistributing human resources within meso- and macro-territorial systems. Using the example of the Volga-Ural macro-region in Russia, the main areas with varying growth potential are considered. Special attention is given to the semi-peripheral or equilibrium zone.

The problem of solid municipal waste (SMW) management in Russia is becoming increasingly relevant, requiring the implementation of effective territorially-oriented solutions. The article analyzes the issues of optimizing the placement of SMW collection and processing facilities using the example of Balashovsky district of the Saratov region. The main focus is on using linear programming methods and geoinformation modeling to select optimal locations for waste processing plants.
