Abstract

In the research, a spatial analysis of the degradation of Samara region agricultural land with the assessment of economic losses due to water erosion is carried out. A map chart of the distribution of districts with different degrees of erosion has also been developed. The values of the degradation factor coefficient and economic losses due to the influence of erosion processes are calculated. The key points of antierosion territory organization and land regulation depending on landscape nature and kind of damage are represented. The plan of action for the antierosion territory organization of a farm in Kinelsky district is proposed and its effectiveness to stop and prevent erosion processes, as well as for rational use of land and increase soil fertility is shown.

Highlights

Water erosion, as a natural process of moving soil solid matter and ground due to the influence of water flows, occurs almost everywhere
The aim of the research was a spatial analysis of the agricultural land degradation in Samara region with an assessment of economic losses because of water erosion, and the development of a plan of action for territory organization and antierosion soil protection
Samara region is located in the southeastern part of the East European (Russian) Plain, in the middle course of the Volga river, which divides the territory into the rightbank and left-bank parts

Summary

Introduction

As a natural process of moving soil solid matter and ground due to the influence of water flows, occurs almost everywhere. It is typical for most agricultural regions of Russia. Its consequences appeared in the form of soil degradation depending on the topography and afforestation of the land, the soil cover, and climate characteristics. In the economically developed lands, erosion is a source of environmental pollution by chemical soil components and introduced pollutants. It is one of the primary cause of the siltation of small rivers and degradation of agricultural landscapes. Antierosion protection is the key step in the conservation and rational use of land resources
