The digital transformation of the agricultural sector has received considerable attention due to its potential to increase efficiency and productivity. This paper reviews recent research and publications to identify key themes and gaps in the digitalisation of agriculture. The analysis shows that while some studies highlight the potential benefits of digital agriculture, others emphasise the limitations and challenges associated with its implementation. The case of Ukraine fits into the ‘light digitalisation’ scenario, where agriculture digitalisation is at a basic level, data control is limited, and digital literacy and technology adoption varies among different agricultural stakeholders.To promote the digitalisation process, data exchange between stakeholders such as farmers, government, traders, producers, consumers and AgriTech should be improved. Digital platforms, e-governance, agricultural extension, access to financial services and information exchange are very important for digital transformation. The author explores digital interactions between farmers and agri-tech companies, food traders/producers and consumers, highlighting the elements and benefits of such interactions.The role of the government in creating a reliable digitalisation system and facilitating cooperation between stakeholders is discussed. It proposes the implementation of solutions such as farm management systems, data collection tools, decision support systems and data-driven farming technologies. These solutions facilitate data analysis, informed decision-making and optimisation of farm operations.Challenges and limitations associated with the digital transformation of the agricultural sector are limited financial resources, regulatory constraints, resistance to change, and privacy concerns. Further research is needed to explore data quality standards, data ownership and privacy rules, skills development, modelling systems and digital platforms. JEL classification: H83, O38, Q10, Q18

Russia's war against Ukraine has significantly increased food security risks and caused disruptions in agricultural production, supply chains, and trade, leading to unprecedented levels of global food and fertilizer prices. The current situation in the world agricultural markets by the middle of 2022 has shown the importance of the Ukrainian agricultural sector for the global market of agricultural products in general and the economy of the European Union, in particular. The article examines the place of the Ukrainian agriculture sector in the world agricultural market. The structure of export and import of agricultural products was analyzed. The dynamics of agrarian exports of Ukraine have been studied and the main reasons for its negative change have been determined. It has been established that the main problems during the war for the Ukrainian agrarian sector were: the occupation of Ukrainian territories, breaking of logistic chains inside and outside the country, reduction of the volume of the domestic market, and decreasing purchasing power of the Ukrainian population, insufficient resources for agricultural production, problems with labor force and theft of Ukrainian agricultural machinery and products. The domestic agricultural sector needs support from both the state and foreign funds, organizations, and countries. The Ukrainian government created several programs to support agricultural producers during military operations. In the tax, the support took place at the expense of VAT reduction, payment of taxes for FLP of 1 and 2 groups at will, payment of ERU by the state for the mobilized workers, cancellation of excise tax on oil products, etc. State support of the agrarian sector in the financial sphere is realized by providing access to cheap credits and the opening of new grant programs. Deregulation processes also took place at the state level: cancellation of business inspections, the introduction of the declarative system of business operation, and simplification of customs procedures. The prospects of the agricultural sector in the post-war economy have been studied. In particular, it was found that the key factor of agrarian sector development is people. Important for the recovery of the agricultural sector is the development of agricultural education and science, creation of sustainable chains in the regions, integration with competitive products into world markets, adaptation to the climate, sustainable and ecological agriculture, technological development, and digitalization of the agricultural sector.

The war in Ukraine has caused significant losses to the Ukrainian agricultural sector and threatened global food security. This study aims to comprehensively analyse the impact of the Russian invasion on Ukrainian agriculture in its initial phase, examine the responses of Ukrainian agricultural policy and outline key elements for the post-war development of the Ukrainian agricultural sector. Using a systematic approach that includes thorough data collection and analysis from official sources, the Ukrainian press, relevant legislation and statistical data, our study focuses on the first five months of the conflict, from February 24, 2022 to July 24, 2022, to identify the main challenges during this period. The agricultural policy analysis shows that the Ukrainian government has adopted a reactive approach, including tax simplification, affordable credit, deregulation, financial support for the agricultural sector, reduced prices for inputs and resources to support farmers, and improvements in logistics. Critical factors identified for post-war development include repatriation and agricultural education, support for small and medium-sized farms, integration into global markets, emphasis on organic practices and sustainable development, and digitalization in agriculture. The integration of a systematic overview of the Ukrainian agricultural sector and an analysis of key elements of post-war development provides essential insights for policy-makers and researchers concerned with the impact of war on the agricultural sector and food security.

With the significant growth of the cyber environment over recent years, defensive mechanisms against adversaries have become an important step in maintaining online safety. The adaptive defense mechanism is an evolving approach that, when combined with nature-inspired algorithms, allows users to effectively run a series of artificial intelligence-driven tests on their customized networks to detect normal and under attack behavior of the nodes or machines attached to the network. This includes a detailed analysis of the difference in the throughput, end-to-end delay, and packet delivery ratio of the nodes before and after an attack. In this paper, we compare the behavior and fitness of the nodes when nodes under a simulated attack are altered, aiding several nature-inspired cyber security-based adaptive defense mechanism approaches and achieving clear experimental results. The simulation results show the effectiveness of the fitness of the nodes and their differences through a specially crafted metric value defined using the network performance statistics and the actual throughput difference of the attacked node before and after the attack.

This paper aims to provide a retrospective assessment of Ukraine’s state policy concerning state-owned banks and evaluate their impact on the sustainability of Ukraine’s public finances. The research methodology employs an empirical study of the cash flow of public funds to state-owned banks and the reverse cash flow to determine the impact of the activity and stability of public finances. The cash flow to state-owned banks includes the expenditure of public funds for the creation of authorised capital during the establishment of state-owned banks, the acquisition of shares in operating commercial banks, additional capitalisation of state-owned banks, etc. The reverse cash flow comprises dividends paid based on the performance of state-owned banks, as well as revenue generated for public funds through the sale of shares (privatisation) of state-owned banks. This study highlights the costs associated with recapitalising state-owned banks. These costs disrupt the stability of public finances, create additional debt dependency for Ukraine, impose an additional burden on public finances, and lead to structural changes that reduce funding for social spending. As a result, Ukrainian taxpayers are financing the inefficient activities of state-owned banks while experiencing reduced investments in education, healthcare, social protection, environmental protection, and other essential areas.
