Effects of Climate Change on the Dynamics of Crops Yield - Case of Ukraine

Abstract

The purpose of the publication is to determine the influence of meteorological factors on the yield of grain crops in different regions of Ukraine, as well as to study the correlation dependence of grain yield on meteorological factors. The research methodology is represented by general scientific and special methods (use of satellite information, climate models, data from long-term agrotechnical experiments, and statistical information). Empirical-theoretical (heuristic analysis and generalization), system methods, modeling, and formalization methods should be distinguished among the methods; economic and mathematical methods and methods of statistical analysis. The results of the research can be used as a basis for the formation of new strategies for adaptation to climate change in the fields of agriculture, namely crop production. And also, to take into account changes in the planning of grain crops and the organization of the appropriate infrastructure for their cultivation, storage, and sale. This research indicates noticeable climate changes in different regions of Ukraine over the past 24 years in the direction of significant warming, which is accompanied by a decrease in precipitation. These changes directly affect changes in grain crop yields. Originality / scientific novelty. The scientific novelty of this research is in linking meteorological factors, such as average monthly temperature and monthly precipitations with values of grain yield in the regions of Ukraine. Furthermore, this research studies the dependence of grain yields on meteorological factors. Practical value/implications. The results of the research can be used as a base for formulating new strategies regarding adaptation to climate change in the fields of agriculture, namely crop production. As well as for considering changes when planning grain crops and organizing appropriate infrastructure for their cultivation, storage, and sale.
