Since the 1990s, many peatlands that were drained for peat extraction and agriculture in Russia have been abandoned with high CO2 emissions and frequent fires, such as the enormous fires around Moscow in 2010. The fire hazard in these peatlands can be reduced through peatland rewetting and wetland restoration, so monitoring peatland status is essential. However, large expanses, poor accessibility, and fast plant succession pose as challenges for monitoring these areas without satellite images.

The farming system at landscapes preserving and restoring soil fertility of agricultural lands have been developed. Typification of lands was made and the types of agricultural landscapes were allocated: plain, hollow-gully, and gully-field. The analysis of the current structure of arable areas was made and resulted in the assessment of structure's influence on the state of soil fertility. The main degradation processes reducing the fertility of south chernozems were studied. There were proposed the ways of creating the sustainable artificial agricultural landscapes.

Taking into consideration all the data of collectibility of land payments (land tax and rent), the dependence of collectibility of land payments on economic and geographical factors is analysed in municipalities of the Samara region. The factors are defined with the help of mathematical methods, which are closely associated with payments growth from the land area of a municipality and the number of residents. The dependence simulation of the level of land payments on geographical and demographic characteristics has been implemented in a municipality.

Much is reported about the destruction of natural forests and the consequences for global warming, while on the other hand, exotic plantations in some regions struggle to gain public acceptance. The earth's population is projected to rise to around 9 billion by 2050, with a concomitant increase in demand for forest products. Inevitably, forests in general, and managed forest in particular, will be called on to provide an ever-increasing proportion of local supplies and the international wood trade.

The purpose of the research is to find varieties and hybrids of crops that are productive in the irrigated lands of the Foothill zone of the Stavropol Territory. The studies were conducted according to generally accepted methods by B. A. Dospehov, All-Russia Research and Development Inst. of Irrigation Agriculture and the V.R. Vilyams All-Russia Research and Development Inst. of Forages. The investigations revealed that the most productive corn hybrids are Zernogradsky 354 MW and Mashuk 355 MW, their crop yield – 10.2 and 10.9 t/ha.

In the structure of the land fund of the Altai Region the category of agricultural lands is the most extensive, it is more than 11.5 million hectares. More than 6.1 million hectares belong to individual citizens. There are more than 5 million hectares of state and municipal ownership. The rest of the lands are owned by legal entities. There were analyzed the natural and climatic conditions of the land fund of the Altai Region and its patterns in the natural subzones.

Lands of industrial regions are often subjected to long-term contamination with heavy metals such as cadmium, zinc, lead, copper etc. Heavy metals circulate mostly due to water flows, and in the areas with humid (micro) climate, the heavy metal pollution propagates from sources with increased intensity because of acidic environment and soil water logging. We established that natural or artificial drainage effectively increases the washout of heavy metal pollutants due to subsurface and groundwater flows.

The aim of research was to study the advanced reclamation techniques to deal with the irrigated land degradation (the rise of the groundwater, resalting, dehumification, etc.). Research was undertaken in some farms in the dry steppe zone of Saratov Trans–Volga region. The object of research was degrated (hydrogenic, solonized, saline, fractured) irrigated dark chestnut soils. The prediction of water–salt regimes on the basis of mathematical modeling of moisture and salt transfer in soils of aeration zone was carried out.
