The increase in illumination levels in populated areas, including as a result of the implementation of several federal projects, has raised concerns about light pollution caused by artificial lighting. This has led to questions about identifying areas and cities where artificial lighting levels have significantly increased, as well as evaluating the impact of this increase on the environment. Light pollution is considered one of the types of physical pollution, and within this framework, it has been analyzed in the context of the Saratov region.

Introduction. The analysis of long-term and intra-annual changes in surface air temperature at the regional level allows us to track longterm trends in global warming and climate change, and is the basis for decision-making in various sectors of the economy. Theoretical analysis. The modern trends were studied in the surface atmosphere and quantitative changes in annual and average seasonal air temperatures in the Saratov region in the 20th–21st centuries under changing climate conditions.

The record of a mandibular tooth plate of the chimaeroid fish Ischyodus sp. from the Lower Cretaceous deposits of the north of the Saratov Volga River Right Bank is described. The presumed age of the find is the Lower Aptian. This is the first recorded occurrence of chimaeroid remains in the Lower Cretaceous (pre-Albian) deposits of the Middle and Lower Volga regions, and the fourth record in deposits of this age in Eastern Europe.

The article examines the application of topological concepts for analysing the structure and assessing the compactness of a regional settlement system. A methodology is proposed that adapts classical topological invariants to evaluate real transport-planning networks using OpenStreetMap data, taking into account physical-geographical and legislative constraints. Instead of abstract node connectivity indices in the settlement system graph, a new operational indicator – the “exit index” – is introduced.

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.

Archaeology, as a science, is constantly evolving and embracing various interdisciplinary methods. Currently, geoinformation technologies and aerospace remote sensing, along with other remote sensing methods, are becoming some of the primary tools at various stages of archaeological research. This study explores the potential of using open-source remote sensing data to identify archaeological sites.

The article is devoted questions of regional level geosystems landscape zoning with Saratov region’s right bank as an example. Mapping was organized with GIS technologies using on the basis of topographic and thematic maps and space images decoding

The article shows characteristic of regional features of oilfield’s geoecological risk (with Saratov region as an example). Geoinformation systems (GIS) and mathematical and cartographical models as a tool of their analysis are disclosed possibilities of using

The article represents possibilities of GIS technology in addressing the problem of optimizing route of gas main in the Petrovskiy district of the Saratov region. Also classical method of calculating the optimal search area of gas main and major factors that influence the position of the route are represented
