The article provides the possible reasons for the relatively high cancer rates in the Volga Federal District (VFD). The promoting on oncological situation factors are given. Among of them are: low incomes, poor environmental conditions, a high per cent of elderly, bad living conditions, increasing of alcohol consumption.

Indices of continental climate at different time intervals for Saratov and St. Petersburg are calculated. They reflect the tendency of a decrease in continentality, associated with a temperature increase in the winter seasons.

The possible connection was studied between the emission of various subsoil gases and the variation of the vertical component of gravity acceleration caused by the influence of the luni-solar tides. At negative values of tidal acceleration, the average concentration of methane and its homologues is reduced, accompanied by an increase in the average concentration of helium, nitrogen, oxygen, and carbon dioxide.

The key points of the Strategy for socio-economic development of the Saratov region till 2030 against primarily the spatial organization of а manufacturing industry are discussed. The proposed typology of districts is annalysed.

In the article to assess the continentality of the region’s climate at 10 stations in the Lower Volga region, the annual air temperature amplitudes were calculated, and the climate continentality indices were determined according to 5 formulas of different authors. The carried out calculation allows to allocate Zavolzhsky areas of the Saratov and Volgograd areas in region with as much as possible favorable conditions on cultivation of high-protein wheat.

The article compares the significance of the factors of migration attractiveness of the Russian regions on the example of the Volga Federal District (VFD). It is shown that for a short period (2012–2015), there was a significant decrease in the number of factors attracting migrants, at the same time, migration situation in the VFD regions has also changed, sometimes drastically. The study was carried out using multivariate linear regression analysis.

An agricultural production assessment of the unused parts of the Dubkovsky municipality was carried out, identified by the results of the work on the creation of GIS of Saratov region agro-industrial complex in the 2016. In order to involve unused arable land in agricultural production, almost all areas will require land management related to the transformation of land – the conversion of low-fertility soils to arable land.

The structure of population employment, both in the Russian Federation and individual regions, has an impact on the rates of their economic development and the level of incomes of the population. In the article it is proposed to use the method of structural-share analysis to assess the degree of influence of all-Russian and local socioeconomic factors on the employment structure of the population of the Volga Federal District.

The article presents the practical implementation of geomarketing tools and GIS technologies in the search for ways to optimize, as well as more successful operation of the branches of PJSC Sberbank in Saratov.

Pollution of the coastal zone of the sea by plastic debris is an important environmental problem. Especially dangerous are small particles (microplastic), as birds and fish mistake it for food. The article deals with the process of destruction of foamed polystyrene – one of the most frequently encountered pollutants – in the surf zone of the sea.
