It has been proven that the production of grains and legumes may decrease by up to 30% compared to 2021. Wheat production is expected to decrease by 34%, barley by 45%, and corn by 2%, respectively. However, this will not influence the satisfaction of domestic demand for grain and legume products. By the way, buckwheat production by reseeding and changing the structure of crops will make it possible to fully meet the needs of the population and get some residues. As for industrial and other crops, production is expected to decline by up to 30% and sunflower by up to 34%, respectively. The practice of vegetable gardening, popular in the 1990s, becomes relevant again. More and more citizens mention that they have land plots and undertake to cultivate them in order to grow basic products. In rural areas, the tendency toward self-sufficiency can be expanded by breeding poultry and animals, including cattle. It has been analyzed that before the war, wheat, sunflower, and corn accounted for the majority of the harvest since a significant part of it was intended for export. The blocking of ports has shown the disadvantages of exporting large volumes of these crops. Consequently, there is a growing demand for niche highmargin crops (peas, berries, mustard, etc.), the transportation of which is more variable. Thus, there are reasons to believe that such trends will continue in the coming years; however, this will not harm the cultivation of wheat, sunflower and corn as the major crops. It has been indicated that the primary task of the Ukrainian agricultural sector in the conditions of hostilities has become the reliable provision of the population with agricultural products and food. As a result, farmers and private agricultural households have demonstrated their key role in preserving and developing local markets and food supply chains. Thus, the conclusion of the classical agroeconomic theory was demonstrated in practice: the major pillar of the sustainability of small-scale agriculture is not its economic benefits over large-scale agriculture but the important fact that large-scale agriculture is conducted as a capitalist enterprise for the sake of profit and rent, while small-scale agriculture is conducted to ensure the existence of the producer himself. A peasant farmer will not stop farming even if it gives him nothing but an average salary. Therefore, small-scale agriculture can exist and develop with much less income than large-scale capitalist agriculture.
