The article has considered the influence of modern
climate changes on the intensity of erosion processes
within the boundaries of the basic landscapes of the
region. It has given the results of the spatial
distribution of the rainfalls. The most noticeable
climate changes of the Bryansk region are reflected in
the decrease in the activity of erosion during snowmelt
due to the lower amounts of snow and soil frost depth.
In the area, the dynamics of rainfall does not detect a
single trend. The processes of erosion and deflation are
studied in the relationship, the manifestation of these
processes on the territory of the Bryansk region. It has
published the results of the risk analysis of erosion and
deflation on forest soils of the region and justified the
application of G. V. Bastrakov’s method for
modeling erosion-resistant agricultural landscapes.
This approach has a number of advantages over the
other known methods. In our case, regardless of soil
and climatic and geomorphological conditions, the
challenge is to ensure such events in which erosion
resistance of the land will not be below a critical value.
The research results are the initial data in designing
soil conservation activities on the territory of the
Bryansk region. The obtained data of the erosive
properties of soils from climatic changes enable the
study and forecasting of the development of
agricultural landscapes of the region in the medium
term
The article analyzes the experience of zoning of
territory of the Bryansk region on the main factors of
erosion to select the measures to combat it. The
Bryansk region in its present borders, mainly
representing the middle course of the Desna river, has
been considered safe in relation to erosion. The
existing zoning is based on the quantitative
characteristics of the processes of erosion that
primarily allowed us to assess the scale of their impact
on nature and the region's economy. The erosion
zoning was performed on the basis of the map of
erosion-prone land. As a result of study and analysis of
all natural factors of erosion and land of the region
under study the regularities of distribution of land
erosion and intensity of spring rainfall and soil erosion
are detected. Under the leadership of Filin V. I., a
survey of the ravines of the region was conducted and
made the scheme of erosion zoning, according to
which the region is divided into three areas. It is
noteworthy Horinas E. V. research. When divided into
areas it was taken into consideration the need for each
of them specific actions to combat the causes and
consequences of erosion in relation to the peculiarities
of the latter in each district. According to the intensity
of the erosion processes and physico-geographical
zoning of the Bryansk region and the nature of
agricultural land use, specialists of the Bryansk branch
of the Institute "Rosgiprozem" produced erosion
zoning of the territory of the region, which highlighted
seven erosion regions. From the variety of methods for
zoning, the most appropriate in our view are created,
based on the estimated small-scale (medium-scale)
maps of erosion of land, capable of performing the
function diagrams of erosion zoning
The article defines the importance of growing potatoes in the Bryansk region. We carried out spatio-temporal re-search of the condition of the industry and identified key shifts in its development over the past 10 years. The pro-portion and its shifts were showed as well. We calculated ranking of administrative areas for potato production in general and by individual categories of farms for the period from 2008 to 2018. It allowed us to find out rates of spatio-temporal movements. The analysis showed increase of concentration and differentiation of growing potatoes in the region
