The article is aimed at suggesting directions of formation of institutional support for introduction of the innovative financial-economic instrument of the internal carbon market (ICM) of the sector of agricultural land use and highlighting aspects of development of its legislative provision. The relevance of the suggested instrument is underlined by the necessity for Ukraine to fulfill the obligations under the Framework Convention on Climate Change of the UN, the Kyoto Protocol, the Paris Agreement, which are aimed at counteracting climate changes and adapting to their consequences. Through the use of the method of statistical analysis together with the analysis of dynamics of land-use categories in terms of farmlands, it has been proved that existing approaches to agricultural land use have a negative impact on the level of agri-ecological and food security of the State, lead to the loss of fertility and contribute to the increase of carbon emissions from the reservoir of mineral soils. The proposed approach forms the bases of further scientific and methodological developments for elaboration of the theoretical, normative-legislative, organizational and economic directions of development of the ICM of the sector of land use. The aspects of further improvement of legislation and of positive influence of ICM on the associated economic sectors are displayed.

The ecotoxicological hazard assessment of pesticide use on crops was performed. The study was conducted in 2021-2023 at the experimental field of the Skvyra Research Farm of the Institute of Agroecology and Environmental Management of National Academy of Agrarian Sciences of Ukraine, located in the Forest-Steppe zone of Ukraine. The influence of herbicides, insecticides, and fungicides on the formation of environmental hazards in crop agrocenoses was studied: experiment (1) - peas, winter wheat, buckwheat; experiment (2) - winter wheat, buckwheat, oats. The ecological risk was assessed taking into account the ecotoxic properties of the chemical active ingredients of pesticides. It was found that the main parameters characterizing the occurrence of environmental risks are: (i) the pesticide load, i.e. the amount of toxicant applied per unit of sown area; (ii) the ecotoxicity of the pesticide (LD50), which is established by hygienic standards; (iii) the persistence of the pesticide in the soil, namely, its half-life (DT50), etc. The calculations proved that the pesticides used had a low environmental risk of impact on agrocenoses. This is evidenced by the ecotoxicity index (E). The total pesticide load (ΣE) on the agrocenosis of each crop during the three years of the study (2021-2023) was calculated. It was found that in experiment (1) - ΣExperiment 1 = 0.23 conventional units (c.u.); in experiment (2) - ΣEexperiment 2 = 0.04 c.u. The results obtained indicate an insignificant environmental risk of pesticide use for experimental plots of crops of the studied farm. However, prolonged use of pesticides certainly leads to the concentration of their persistent residues in the soil. This can lead to contamination of crop products and environmental. The cereals (buckwheat and oats) grown on the farm are intended for dietary consumption. To confirm the reliability of the hypothesis of the safety of the obtained grain and cereal products, it is advisable to further study their quality in terms of pesticide residues. It is shown that this methodology can be used to assess the risk of pesticide contamination of an agroecosystem. The ecotoxicity criterion (E) can be considered as a management tool for reducing environmental risks in agroecosystems. [ABSTRACT FROM AUTHOR]

The purpose of this study is to analyse the use of agricultural land on the territory of united communities and their individual districts of Zhytomyr region as the smallest units of the administrative territorial division of Ukraine. The relevance of this study, due to current changes in national land relations, dictates the need to have information about agricultural lands, their owners, tenants and the lands status for planning agricultural production, the land-leases development, sale of land. The analysis of land use was carried out according to the following indicators: location of land plots of all owners within the community district and the whole community; their area; monetary evaluation; status of documents for each land plot, in particular the availability of lease, land cultivation presence. The initial data of the researches is the data of the state land cadastre database, and data of the real property rights register, both in general access and in need of special access. As a result of the research there were defined areas and location of lands of some landowners, who leased their lands and areas of lands not leased, also there were defined areas of lands, used illegally, without any documents on land use, defined areas of lands, used or owned by agricultural producers (farms, physical persons, legal entities). A cartographic core was created for the purpose of convenient planning of agricultural land use and land management within selected districts on the territory of the community.

The COVID-19 pandemic, creating massive social and economic challenges, has started additional risks in ensuring balanced forest land use at the national, regional, and global levels. In this regard, the issues of preserving ecosystems and improving the well-being of citizens, avoiding the risk of deforestation and degradation of forests due to the negative impact of the pandemic on the economy of the forestry sector have become relevant. The article's purpose is a theoretical and methodological substantiation of ensuring a balanced use of forestry lands in the context of the COVID-19 pandemic, which is associated with economic regulation, investments, and the level of financial support. The object of this study is five state forestry enterprises of the Small Polissia region of Ukraine, referred to the jurisdiction of the State Forestry Agency. The main economic problems and financial needs of the studied state forestry enterprises were identified by analyzing the dynamics of their income, the level of depreciation of fixed assets, the volume of capital investments, labor productivity, and workers' wages. Based on the analysis of reporting indicators of state forestry enterprises in the Small Polissia region of Ukraine, conceptual frameworks for coordinating efforts to ensure the balanced use of forestry lands in Ukraine have been prepared. Measures were proposed to help mitigate the impact of the COVID-19 pandemic on the social and economic dimensions of forestry land use. Recommendations for financing forestry activities, accelerating transformational changes in investment support of the forestry industry, revising the tax burden on state forestry enterprises have been substantiated. Balanced forest land use can reduce the risk of future pandemics. Therefore, its financing and incentives based on economic preferences should be a public policy priority on sustainable development.

The impact of the phases of the solar activity cycle on winter wheat production in different physiographic zones of Ukraine: Polesie, Forest-Steppe and Steppe have been researched. Particular attention is paid to indicators of yield that have a significant impact on the development of agricultural industries. A correlation dependence between the yield of winter wheat and the phases of the cycle of solar activity was established. With a proper research of these indicators, the sectoral structures of agro-ecosystems can predict for income or prevent the growth of zonal costs in social production. The optimal periods for obtaining high and stable yields of the studied culture connected with the physical factors of nature are determined. That is why a large role is played by the scientific understanding and practical use of each individual phase of the solar activity cycle in agroecosystems, which enables a business entity to obtain a reasonable dynamic system by their periodic changes. At the same time, and is a prerequisite for control at all stages of culture production. [ABSTRACT FROM AUTHOR]
