Abstract
This paper discusses issues related to environmental problems that arose as a result of the virgin and fallow lands development in Kazakhstan in the second half of the twentieth century. The authors emphasize that the level of agricultural production in the post-war years failed to meet the needs of Soviet citizens. Under these conditions the massive plowing of land had to solve a whole range of tasks, first of all, to solve the problem of food hunger by means of a huge increase in the area for sowing grain crops. According to the authors, solid tracts of plowed soil, having a dark color, became very hot, provoking drought, which, with chronic manifestation, caused aridization of the entire steppe zone, causing significant drying up of rivers and lakes. The authors believe that large works on the virgin lands development have made serious changes in the nature of the region. Stocks of valuable hunting and game species of animals were undermined, and in some places completely destroyed. Taking advantage of the lack of control, the new settlers along with the local residents mercilessly consumed the gifts of the environment, which gave rise to massive poaching. The methodological basis of the study was the complex use of various approaches, methods and assessments used in interdisciplinary research.
