Abstract

Drought, as one of the consequences of contemporary warming, has become one of the main topics discussed by researchers at the moment. Thus, with an increase in the temperature, there observes the decrease in the precipitation, an increase in the frequency of the drought in some regions of the world. Naturally, in this case, the threat of the decrease in crop yields and agricultural productivity is inevitable. Of course, in some regions, the revers processes can occur, in which an increase in the temperature can lead to the increase in the precipitation, the decrease in the tendency of the drought, and in this case productivity can increase. On the other hand, methods are presented to determine the probable risks of each of processes that will affect the dynamics of the productivity during the warming period. For this purpose, it is proposed to use the trend angle coefficient.
