Ukraine’s commitments under the international framework agreements to reduce CO ₂ emissions and the Global Climate Change Initiative provide the basis for the implementation of bioeconomy mechanisms in the country’s Energy Development Strategy until 2035. One of the goals of this strategy is to reduce the consumption of fossil fuels and switch to alternative fuels. The agriculture of Ukraine is assigned the leading role in ensuring the replacement of fossil fuels with biomass of plant origin. The bioenergy potential of the agro-industrial sector of the economy requires extensive research in order to determine and integrate it into the country’s energy sector. The essential characteristics of energy efficiency in the context of the cluster model of organizing the activities of enterprises for the production of biofuel as stable interactions of geographically concentrated economic entities are investigated in this article. Peculiarities of introduction of bioenergy clusters as stable interactions of geographically concentrated business entities (enterprises, suppliers and organizations, including scientific institutions, etc.) have been determined according to a pre-defined and agreed development strategy for all participants without exception at the stage of formation of which the competitive environment is supported taking into account the energy, ecological and socio-economic parameters of the sustainable development of territories. A model of a territorial bioenergy cluster for the production of biofuels from crops and waste was formed and the advantages of creating bioenergy clusters were analyzed. Furthermore, a matrix of a PEST analysis of the formation of bioenergy clusters in Ukraine was formed.

The specificities of the sowing and harvesting campaign of 2022–2023 in Ukraine and its impact on the world energy and food market in the conditions of the full-scale invasion of Ukraine by the Russian Federation are analyzed in this paper. The purpose of the study is to determine the role of Ukraine in ensuring energy and global food security, to analyse the situation regarding the possibility of conducting a sowing and harvesting campaign in Ukraine in the conditions of hostilities and to provide recommendations on preserving the potential of Ukraine in meeting the energy and food needs of Ukraine and other countries. The provided analysis of data of the Food and Agriculture Organization (FAO), the State Customs Service and the State Statistics Service of Ukraine has confirmed the role of Ukraine in ensuring energy and food safety of many countries in the Middle East and North Africa, which are the main importers of agricultural products from Ukraine. It has been found that the 2022–2023 sowing and harvesting campaign in Ukraine is facing a number of problems, including: military operations over a large area, which makes it impossible to conduct agrotechnical activities in a timely manner; a lack of seed material due to its systematic destruction by the Russian military; problems with the supply of fuel and lubricants (systematic shelling and destruction of oil bases throughout Ukraine); problems with the supply of fertilizers; bombing wheat fields and food warehouses; blocking Ukrainian sea ports; mobilization of a significant part of the population in the ranks of the Armed Forces of Ukraine; logistics problems. The study proposes recommendations to preserve the potential for meeting energy and food needs in Ukraine and for countries importing agricultural products from Ukraine.
