The purpose of the paper was to assess the impact of climate changes on agricultural development and food security in Ukraine and Slovakia using statistical data from Statistical Office of the Slovak Republic, State Statistics Service of Ukraine, Eurostat, Food and Agriculture Organization and other sources. The comparison method was used to evaluate changes in agricultural development indicators, as well as climate changes in 1998-2021 in Ukraine and Slovakia. The main indicators of agricultural development used in the research were agricultural raw materials exports(%), agricultural raw materials imports (%), agriculture value added (% of GDP), agriculture value added (annual % growth), agriculture value added (current US$), cereal production (metric tons), cereal yield (kg per hectare), crop production index, food production index. Correlation and regression equations were used to establish the relationship between climatic factors and agricultural development indicators. The multiple correlations between air temperature and indicators of agricultural development was r=0.75 for Ukraine, r=0.69 for Slovakia. Using neuromodeling tools, the indicators of cereal production volumes and cereals yields in Ukraine and Slovakia in 2024-2033 were predicted. Tables were used to summarize the results. In conclusion, it should be noted that climatic conditions should be analyzed in each sector of crop production, and measures should be taken to adapt technologies for the gradual expansion of obligations for the production and export of agricultural products to world markets.

The aim of this paper is to justify the strategic priorities of financial provisions for sustainable soil management in agriculture of Ukraine. In conditions of limited financial resources, there is a need to identify the top priorities of sustainable soil management. The study found that the most important priority of financial support for sustainable soil management is to suspend the decrease of the content of humus and achieve its deficit-free balance (global priority - 0.556); the second position is occupied by the protection of soils from erosion (priority - 0.274); third place - enrichment of soils with nutrients substances (priority - 0.101); fourth place - amelioration of acid and solonets soils (priority - 0.069). In the context of identification of priorities of financial support for practical implementation of the proposed conception of sustainable soil management this paper also addresses the empirical expert evaluation of the relative importance (significance) of the principles of sustainable soil management, as well as the level of adherence (compliance) of these principles in agricultural enterprises of Ukraine. The obtained results demonstrate the state of compliance with the principles of sustainable soil management in agricultural enterprises, the availability of opportunities and reserves for improving the situation for their implementation, and as well due to which this should be carried out. Thus, 77.8 % of the principles were implemented at a low level, the rest (22.2 %) - at a very low level, so there are significant reserves to improve the situation. [ABSTRACT FROM AUTHOR]

The article examines the prospects of Ukraine on the world grain market and ways to increase the efficiency of maize cultivation using environmentally safe technologies in the conditions of the negative impact of climate change and other stress factors. The methodological approach takes into account the peculiarities of agrarian production based on the use of data of the Food and Agriculture Organization of the United Nations, United States Department of Agriculture, United Nations, Ministry of Agrarian Policy and Food of Ukraine and State Statistics Service of Ukraine. The dynamics of world production and export of maize grain, sown areas, production and yield of maize in Ukraine are demonstrated, which directly focuses attention on the competitiveness of Ukrainian maize on the world grain market. These arguments are confirmed by analytical results, which show that in 2022, among the world leaders of maize grain producers, Ukraine took fifth place, and among exporters - fourth. In order to mitigate the impact of climate change and other stress factors on the effective production and export of Ukrainian maize, adaptation measures are proposed, which consist in the application of modern technologies, which include: optimization of the structure of sown areas and scientifically based crop rotations with the effective use of competitive varieties and hybrids of agricultural crops, the introduction of organic and mineral fertilizers and plant protection products, the use of soil protective tillage, sideration and mulching, irrigation systems, and also the productive use of plant residues with the application of modern biodestructors. Their comprehensive implementation will contribute to the development of maize yield, grain quality, preservation of biodiversity and the solution of the grain-food problem in the world.

This paper studied the economic assessment of soil carbon sequestration and financial support for development of low-carbon land use in Ukrainian agriculture in the context of climate change. Results of evaluation show that Ukraine plays a strategic role in the soil carbon sequestration in Europe. Ukrainian soils contribution is equal to one third of SOC sequestered in agricultural soils of the European Union. Economic assessment of stocks of SOC in Ukrainian soils indicates that its value is in the range from 14.4 thousand USD/ha (Gray forest soils) to 103.7 thousand USD/ha (Chernozem-meadow soils). The results of analysis revealed that for agricultural production and the formation of the economic fertility of soils in Ukraine, the effects of climate change on warming will be both positive and negative. Taking into account the international experience of adaptation of land use processes to climate change, the basis of strategy of adaptation of agriculture in the enterprises of Ukraine to warming is proposed to put the concept of low carbon land use. As a result of the study it was determined the macroeconomic assessment of the need of financial resource for development potential of low carbon land use in Ukraine for the period until 2030.

The purpose of the article is multi-year research and analyze of the dynamics of cultivated areas, production volumes and yield of cereal crops in Ukraine, in the context of world cereals production and export. Ukraine's prospects on the world cereals market have been established thanks to the formation of ways to adapt the production of wheat, barley and maize to the conditions of climate change. Graphically illustrated data of the State Statistics Service of Ukraine on cultivated areas, production volumes and yield of cereal crops in Ukraine, data of the Food and Agriculture Organization of the United Nations on world cereals production and export. It was established that the production of cereal crops in Ukraine during 1990-2021 increased by 69% - from 51.0 to 86.0 million tonnes thanks to an increase in maize production almost 9 times - from 4.74 to 42.1 million tonnes due to the growth of its of cultivated areas by 4.5 times - from 1.23 to 5.52 million hectares. During 2008-2022, the world production of cereals increased by 32%, and the world export of cereals increased by 76%. At the same time, the transformation of the structure of cultivated areas, climatic changes and the war of the rf against Ukraine led to the yield of cereal crops being much lower than the potentially possible level. For effective cereals production, a number of adaptation measures are proposed to overcome the negative impact of climate change, which consist in the use of innovative technologies in environmental and genetic research, which ensure the cultivation of highyielding varieties and hybrids of cereal crops that are resistant to drought, diseases and pests, as well as the optimization of cultivated areas with the introduction of scientifically based crop rotations and organic technologies.
