Climate change threatens crop yields through changes in temperature, precipitation, and more significant changes in weather conditions. Thus, it is important to monitor the potential impact of changing weather parameters on crop yields in order to adapt to climate change. Ukraine is of particular interest in this regard, as this country is an important player in the world grain market due to its large area of agricultural land. Historical climate data already indicate an increase in temperature in Ukraine, and climate forecasts show a further increase in temperature, especially in the South of Ukraine. Therefore, the purpose of the article is to determine the impact of climate change on agricultural land use in Ukraine. The global trends of climate change, which is one of the most urgent threats with a long-term negative impact on the population, the environment and the economy, have been studied. The impact of global climate change on land resources, agriculture, forestry, water resources, energy, infrastructure, biodiversity, public health, emergency situations is analysed. The article describes the most noticeable manifestations of global climate changes on the territory of Ukraine, researches and summarizes their consequences on agricultural land use. The potential impact of climate change on the yield of major agricultural crops and possible economic losses are analysed. The article summarizes the results of studies of the dynamics of changes in climate indicators (air temperature and precipitation), the main consequences and risks of climate change for the agricultural sector of Ukraine are given.

The indirect approach is mainly used to assess the forest-growing potential of lands in the forestry of Ukraine. For these purposes, a comparative ecological (forest typological) method is used to assess soil conditions according to their forest growth effect. The species composition of the forest stand and its productivity are the main indicators of the forest growth effect. The undoubted advantages of this method are high forestry value, low labour intensity and cost, and the main disadvantages are the subjectivity of determining the types of forest conditions (especially derivatives and artificial plantations), its insufficient environmental sensitivity, and the difficulty of applying to places where there is no forest vegetation. The aim of the study was to quantify the quality of forest land and develop markers of the forest-growing potential of soils. The studies were carried out by synthesizing two methodological approaches – forest typological as the leading method for assessing the potential of habitats and direct study of soils (field and analytical). The package of markers was developed to assess forest potential of soils based on the establishment of a correlation between the productivity of forest stands (height, quality class) and soil indicators (thickness of the humus part of the profile, pH, content of clay particles, humus, total and exchange forms of N, P, K, Ca, Mg). The package of markers depends on the soil type and consists of the following soil indicators: the content of particles of physical clay (d<0.01 mm), the thickness of the humus part, as well as the content of humus, N, Ca, K, and Mg. A gradual increase in their quantitative values leads to increase in the forest productivity of the soil and, as a result, the productivity of the forest stand.
