FEATURES OF THE IMPACT OF ANTHROPOGENIC AND CLIMATIC FACTORS ON THE STATE OF AGRICULTURAL LANDS IN ZAPORIZHIA REGION

Abstract

Purpose: to substantiate the features of the impact of anthropogenic and climatic factors on the condition of agricultural lands in Zaporizhia region. Discussion. The intensive agricultural use of soils in Zaporizhia region has led to a number of negative environmental changes and deterioration of their properties. The main factors of anthropogenic impact of agriculture on land resources are the irrational use of agricultural land, agricultural sphere pollution, plant chemicalization, scientifically unsubstantiated application of organic and mineral fertilizers. The negative impact is an increase in the disturbed lands area and the lack of reclamation. High ploughing of agricultural lands in Zaporizhia region (84.8 %), the use of heavy tillage machinery, erosion control measures neglect, as well as the ineffective use of funds aimed at erosion control, lead to an increase in eroded lands. The special military operation conducted in the Zaporizhia region also had a significant impact on the land fund structure. The region belongs to the zone of risky agriculture, which is associated with insufficient natural moisture against the background of increasing air temperature. Reduction of the negative impact of air and soil drought on the agricultural crop productivity can be achieved through irrigation. However, with the Kakhovka reservoir dam destruction, irrigation of fields became impossible. Conclusions. Significant anthropogenic impact on the region territory is associated with agricultural production, namely, with crop production and, accordingly, high agricultural development of the territory. The intensity of adverse natural processes depends on the natural features of the territory – relief, soil type and their mechanical composition, climatic indicators and wind exposure. As a result of the analysis of soil and climatic conditions of Zaporizhia region, the relevant data is presented.
