“…Based on the aforesaid, there is a need to study climatic factors on the basis of nonlinear dynamics methods that take into account the current volatility of natural processes and phenomena, namely the fact that the grain crop production productivity predicting develops along cyclic trajectories, the stability of the characteristics of which is much higher than the stability of the periodicity of separately selected points of the process. A qualitative grain crop production productivity forecast and scenarios of its development dynamics will allow the DM (decision maker) to control and regulate the ambitious plans of Russian producers, prescribed in the Long-term strategy for the development of the grain complex of the Russian Federation until 2035, according to which the gross harvest of grain and leguminous crops for 2020-2035 should grow by 27.3%, and the volume of exports should increase by 83% [1] and assess the prospects for the necessary reserves and grain reserves creating [9,10,11,12], intended for guaranteed supply of the country, taking into account the agro-climatic and geographical features of the macro-regions.…”
