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.

Wetlands are the most important natural resources; they are the sources of biological, cultural, and economic diversity. The article presents an analysis of the current situation of the wetland area in Klaipeda County. Analytical, comparative, statistical, and logical analysis methods were used for the investigation. The aim of the investigation is to carry out the analysis of Klaipeda County’s wetland area during the period between the years 2002 and 2022. In 2022, wetlands occupied 1.21 percent of Klaipeda’s County, i.e. 6,337.53 ha. In 2002, the area of wetlands in Klaipeda County was 1.68 percent and occupied 8,748.33 ha. So, in Klaipeda County during the period between the years 2002 and 2022 wetland area decreased by 2,410.80 ha or 27.56 percent. After the analysis of the change in wetland areas in the districts of Klaipeda County, it can be seen that in all municipalities, wetland areas decreased in the period of 2002–2022. Many wetlands in Klaipeda County have been exploited and managed for various purposes. Large wetland areas have been drained and reclaimed mainly for agriculture and the establishment of human settlements. Monitoring and inventory of wetlands are important for of conserving and managing wetland resources. An important element of all peatland restoration projects is a programme of monitoring to check results and progress. The aim of the investigation is to carry out the analysis of the Klaipeda County wetland area during the period between the years 2002 and 2022.
