Agricultural Global Value Chains (GVCs) link input suppliers, primary production, processing, and consumption across borders but are increasingly exposed to upstream disruptions. This study develops a network-based Leontief framework to analyze international trade in agricultural GVCs, explicitly modeling fixed-proportions technologies, intermediate input dependence, trade costs, and capacity constraints. It traces how final demand and supply-side shocks propagate through multi-country input–output networks, affecting both quantities and prices. A stylized numerical illustration motivated by war-related disruptions in Ukraine demonstrates how export constraints, trade frictions, and fertilizer shortages can be represented within the proposed framework. The illustrative exercise shows how nonlinear downstream effects may arise mechanically within a fixed-coefficient production network when upstream constraints bind. Fertilizer availability is treated as a potential amplification channel rather than as an empirically estimated determinant of output losses. Full article

Contemporary post-war cities increasingly require adaptive urban systems capable of addressing climate vulnerability, infrastructural instability, environmental degradation, and human well-being simultaneously. This study develops an interdisciplinary framework for adaptive biophilic infrastructure and resource governance within the context of sustainable post-war reconstruction in Ukraine. The research combines literature analysis, comparative urban assessment, and experimental evaluation of eco-modified construction materials. Particular attention is given to vertical greening systems, adaptive underground infrastructure, daylight-integrated public environments, multifunctional urban systems, and environmentally responsive concrete composites incorporating porous minerals and plant-based biomass. Comparative examples from Montreal, New York, Seoul, and Singapore are examined alongside differentiated Ukrainian urban contexts, including Kyiv, Kharkiv, Dnipro, Odesa, Kherson, Lviv, and Uzhhorod. The findings demonstrate that adaptive biophilic infrastructure may improve urban microclimates, strengthen thermal and acoustic regulation, enhance infrastructural adaptability, and support psycho-emotional comfort within dense and post-conflict urban environments. The study further indicates that underground and layered urban systems increasingly function as multifunctional socio-ecological infrastructures integrating mobility continuity, environmental regulation, public accessibility, emergency protection, and human-centered spatial resilience. The experimental assessment demonstrates that eco-modified materials contribute to moisture stabilization, thermal buffering, acoustic moderation, and passive environmental regulation within adaptive urban systems. The incorporation of porous mineral additives and plant biomass improved the environmental responsiveness of the investigated composites while supporting more resource-efficient construction approaches. The study concludes that sustainable post-war reconstruction requires a transition from fragmented technological interventions toward integrated socio-ecological urban frameworks capable of combining environmental regulation, infrastructural resilience, resource efficiency, adaptive governance, and human-centered spatial design within long-term urban sustainability strategies.

Russia’s invasion of Ukraine has exposed millions of individuals to traumatic experiences, displaced them under temporary protection, and caused psychological distress. This exploratory study examined resilience, emotional experiences, and psychosocial profiles among displaced and non-displaced Ukrainian women affected by the war. A total of 249 adult women participated, including 122 displaced women under temporary protection residing in Spain and 127 women living in Ukraine. Participants completed the Brief Resilient Coping Scale (BRCS) and the Scale of Positive and Negative Experience (SPANE). Group comparisons and cluster analyses were conducted to identify distinct psychosocial patterns. Displaced women showed slightly higher resilience scores than non-displaced women, although differences were not statistically significant. Non-displaced women reported significantly higher levels of both positive and negative emotional experiences, suggesting greater emotional intensity among those remaining in Ukraine. Cluster analyses identified three psychosocial profiles: an adaptive profile characterized by high positive affect, low negative affect, stronger social support, and higher resilience; a vulnerable profile marked by low social support, elevated negative affect, and lower resilience; and an intermediate profile showing high negative affect despite moderate-to-high social support. Although displaced women under temporary protection were more represented in the vulnerable profile, this association was not statistically significant. The findings highlight the heterogeneity of psychological adaptation during war and displacement and emphasize the protective role of resilience and social support. Full article

This study investigates the cross-border consequences of large-scale military attacks on Ukraine’s critical energy infrastructure and their implications for European energy resilience. Unlike prior research focused primarily on national-level disruption, this paper conceptualizes wartime infrastructure destruction as a source of systemic spillover risk within interconnected electricity systems. We develop an analytical framework integrating three dimensions: shock probability, structural vulnerability, and recovery capacity. Using evidence from 2022–2026 and comparative assessment of selected European Network of Transmission System Operators for Electricity (ENTSO-E) countries, we identify substantial asymmetries in exposure and resilience. Moldova appears highly vulnerable due to structural dependence and limited flexibility, whereas Poland demonstrates stronger resilience supported by diversification and institutional capacity. The findings show that shocks originating in Ukraine propagate through electricity trade flows, balancing constraints, and price volatility. The results highlight that large-scale attacks on the energy system threaten not only immediate regional security but also the long-term energy sustainability of the interconnected European network. The paper contributes to the literature by linking war-induced infrastructure damage with sustainable energy governance and by proposing resilience tools such as digital twins and blockchain coordination. The results are relevant for policymakers, transmission operators, and crisis management institutions across Europe. Full article

Small rural businesses face significant challenges due to geographical constraints, transportation costs, small market size, and low population density. On top of that, the energy crisis that arose after the start of the 2022 Russia–Ukraine war and the sanctions imposed by the EU and the US have created a stifling energy environment. The latter has exposed the businesses to the risk of energy poverty. The current study examines energy poverty within three business sectors that are prominent in the Greek countryside. These are entities firstly involved in the processing, manufacturing, and standardization of agricultural products; secondly, involved in the trade of agricultural products; and lastly, certain businesses operating in the tourist area. More specifically, this research examines the energy needs and energy obligations of these businesses as well as the energy efficiency of their facilities by simultaneously exploring the impact of European and national energy policies on addressing energy poverty in rural micro-businesses. To detect the opinions, experiences, perceptions, estimations, and expectations of entrepreneurs who maintain these businesses in rural areas, a qualitative approach was adopted utilizing personal in-depth interviews. Overall, fifteen micro-entrepreneurs were interviewed. Findings revealed that energy costs for rural businesses are becoming a major issue for their survival. Moreover, they have a substantial effect on their operational costs, exceeding other expenses and leading to an increase in energy poverty. These findings have also been confirmed by statistical data. Energy costs for small businesses range from 15% to 35% depending on the business, and during peak periods or crises, they exceed 40%. In addition, fees and taxes account for over 40% of electricity bills. Full article

This article examines how sacred vocabularies from Orthodox Christianity and Judaism function in racialised public discourse in Poland and Ukraine between 2020 and 2025. It asks how terms such as imago Dei/tselem Elohim, neighbour-love and chesed, holiness/purity, suffering/martyrdom, and exile/return are mobilised across pulpit, policy, and platform communication. Drawing on a corpus of 23 publicly available texts, the study applies comparative rhetorical discourse analysis informed by Burke’s concepts of identification and logology and Pernot’s account of the religious dimension of rhetoric, alongside a coding scheme focused on topoi, metaphors, frames, appeals, and boundary work. The findings show convergences in dignity claims, memorial warning, and care rhetoric under conditions of war and displacement but also clear divergences: Jewish discourse more often mobilises peoplehood as a rhetoric of continuity and communal protection, whereas Orthodox discourse more often ties sacred language to national-historical self-location, ecclesial autonomy, and opposition to russkii mir (“Russian world”). Across the retained corpus, dog-whistle-like discourse appears mainly as an object of quotation or denunciation, while explicit counter-speech is widespread. The article concludes that sacred language remains an active rhetorical resource for defining dignity, injury, solidarity, and belonging, although its function varies across arenas, traditions, and the corpus’s asymmetries.

This paper assesses the role of green hydrogen and green ammonia in the low-carbon reconstruction of Ukraine’s energy sector. The country, severely affected by war, has more than 70% of its energy infrastructure damaged or destroyed, which calls for novel solutions for not only reconstructing but also rethinking Ukraine’s energy sector shaped by the Soviet-era planning. In this context, decentralized and renewable energy solutions appear to be one of the best options to achieve this goal. This study combines four novel and mutually reinforcing methods: a Scopus-based literature review of highly cited green hydrogen publications, natural language processing (NLP) and bibliometric network analysis of Ukraine-related hydrogen research, a SWOT assessment, and a geospatial hydrogen production cost model (GEOH2). The novelty of this research lies in this integrated Ukraine-specific framework, which links research trends, wartime reconstruction constraints, hub-level policy choices, and financing risk-sensitive cost modeling. Therefore, the quantitative part of GEOH2 estimates the levelized cost of green hydrogen, while ammonia is treated as a downstream screening-level conversion and export pathway rather than as a full plant-level ammonia model. Our results show that Ukrainian green hydrogen research is concentrated on renewable-energy strategy, wind and solar electrolysis, water and desalination constraints, gas grid blending, underground storage, ammonia derivatives, and decentralized energy systems. The GEOH2 results indicate that southern Ukraine has strong physical potential for competitive green hydrogen production under de-risked financing, while war risk financing can make even resource-rich areas economically unattractive. Odesa and Dnipro emerge as important export-oriented and industrial hubs, whereas Zakarpattia remains strategically relevant as a safer western corridor linked to European markets. Our findings demonstrate that Ukraine’s hydrogen and ammonia development needs to follow a phased pathway: domestic renewable build-out and grid repair, pilot electrolysis projects and screening-level ammonia conversion pathways, targeted de-risking and insurance mechanisms, and only then broader export corridor development. This pathway can support decarbonization, energy security, industrial modernization, and Ukraine’s long-term integration into European clean energy value chains. Full article

Sustainable agriculture has been a focus of research for over three decades, gaining particular urgency with the escalation of global conflicts, especially the Russian–Ukrainian war. Selecting appropriate parameters for objectively assessing sustainable agricultural development remains challenging, with limited studies addressing the aggregation of all relevant indicators into a single analytical framework. Given that these indicators and their quantitative values change annually, continuous updating and analysis are essential. This study was guided by selected SALSA/PRISMA principles to structure the indicator-selection process for examining Ukraine’s agricultural sector, which is vital to both national and global food security and accounts for approximately 10% of GDP, more than 50% of exports, and nearly 17% of employment. Alongside climate change pressures, the sector faces severe disruption from military aggression, undermining its economic contribution and stability. This research identifies and selects the most relevant economic, ecological, and social indicators to assess sustainable agricultural development in Ukraine, comparing values before and during the war. Based on these, this study proposes the Sustainable Agriculture Index (ISA), an aggregated measure that integrates multiple dimensions of sustainability. The ISA was calculated using a normalized weighted aggregation approach across economic, environmental, and social indicators. This approach enables a comprehensive evaluation of Ukraine’s agricultural resilience and its capacity to contribute to sustainable development under crisis conditions. Full article

This study examines how Ukrainian enterprises of different size classes adapted their trade activity under the compounded shocks of COVID-19 and the full-scale war. The article addresses national economic resilience and sustainable recovery by examining how export and import dynamics changed among micro-, small-, medium-, and large-sized firms during 2015–2023. The methodology combines the logarithmic decomposition of intensive and extensive trade margins with a strategic positioning matrix based on labour productivity and the net-export coefficient. The results reveal marked size-based differences in aggregate trade-adaptation patterns. During the pandemic, microbusinesses shifted toward a quantity-led compensatory pattern, whereas during the war, medium-sized and large enterprises showed a stronger efficiency-led export pattern. Micro- and small firms displayed characteristics associated with technology-oriented adaptation, combining rapid labour productivity growth with negative trade balances, whereas large enterprises were positioned closer to the niche-exporter profile, supporting the balance of payments but showing signs of slower productivity growth. Medium-sized firms occupied a transformation zone, indicating unresolved adjustment pressure and continued dependence on trade restructuring. These findings suggest that enterprise-size heterogeneity can serve as an analytical basis for differentiated recovery policy. The results are relevant for trade-dependent sectors, including agri-food and food-processing systems, where recovery depends on technological upgrading, export capacity building, and the more effective conversion of imports into future export potential.

Cryptocurrencies have become increasingly in demand in Ukraine’s wartime economy, yet little is known about how entrepreneurs perceive them in terms of trust, business use, and reputation. This study examines trust dynamics in cryptocurrencies among Ukrainian small-to-medium enterprise (SME) entrepreneurs under wartime conditions, exploring their association with business behavior, investment decisions, and reputational perceptions. The analysis is based on a survey of 561 Ukrainian entrepreneurs. The results show a statistically significant increase in trust in cryptocurrencies during the war. Higher trust is associated with more intensive operational use of cryptocurrencies and greater importance in investment portfolios. Entrepreneurs who associate cryptocurrencies with traditional liquid assets are more likely to assign them a stronger investment role. The use of cryptocurrencies affects both cryptoassets’ reputations and entrepreneurs’ business reputations. Greater engagement with cryptocurrencies is associated with a higher likelihood of viewing their use as a reputational advantage. However, overall assessments remain cautious due to regulatory uncertainty, financial risks, and potential involvement in tax evasion or speculative activities. Different perceived value propositions of cryptocurrencies are also linked to distinct behavioral strategies. Overall, the findings suggest that, in wartime Ukraine, trust in cryptocurrencies is shaped by their practical usefulness during periods of financial disruption and by their implications for entrepreneurs’ reputations.

This study assesses liquidity, profitability, and working capital management (WCM) strategy in Polish manufacturing companies in the pressure-casting industry, drawing on evidence from the pre-COVID-19, COVID-19, and Russia–Ukraine war periods. Using panel data from 19 companies representing 90% of the Polish aluminum diecasting industry, we employ non-parametric tests (Mann–Whitney U and Kruskal–Wallis) to analyze the data. The period after the COVID-19 crisis coincides with the Russian–Ukrainian war. These countries are Poland’s neighbors. This period of uncertainty for Poland has led to supply chain disruptions and reduced investments. For manufacturing companies, this is dangerous because they have limited development opportunities. The results indicate the adoption of a conservative WCM strategy in Polish aluminum foundries during the pre-COVID-19, COVID-19, and Russia–Ukraine war periods, characterized by increased inventory levels, extended operating cycles in large firms. Additionally, the results showed reduced the level of receivables in large companies and visible decrease in the level of financial liquidity and profitability—however, these differences are not statistically significant. Polish aluminum foundries are adapting their WCM strategies toward an optimal, conservative approach that incorporates both safe and risky elements to ensure continued operations and profits. In addition, larger Polish aluminum foundries exhibit distinct liquidity patterns relative to smaller foundries, particularly in indicators of inventory, receivables, and fixed assets. In addition, the Russia–Ukraine war period exhibits distinct liquidity characteristics in Polish aluminum foundries compared with the COVID-19 and pre-COVID-19 periods, particularly in inventory turnover and operating cycle. The results of this study offer several novel contributions to the existing literature on financial security indicators by examining unexplored factors related to size and period. The results of this study have several practical implications for business leaders seeking to adopt an optimal liquidity, profitability, and WCM strategy. Full article

Agriculture, as a production sector, is exposed to external shocks. The instability of agricultural markets, changes in prices of inputs, dropping crop prices, or changes in climate patterns put their economic resilience to the test. Agroecological diversification of production is widely cited as a key adaptive strategy to increase farms’ resilience to these shocks. At the same time, empirical evidence linking crop diversity to economic stability across different production systems remains limited. The aim of the study was to assess whether the integration of more complex crop rotations and livestock production increases the economic resilience of organic farms compared to stockless organic farms and conventional farms. The analysis utilized data from the Polish FADN covering the multi-crisis period of 2020–2022, which included the COVID-19 pandemic, Russia’s war against Ukraine, and the sharp rise in fertilizer and energy prices. Farms were grouped by production type. Crop diversity was assessed using the Shannon–Wiener index (H′) and the Pielou evenness index (J′). The economic resilience of tested farms was determined based on their income, income variability during the study period, and the ability to maintain income above the parity threshold. The results indicated the existence of different pathways for building resilience. Organic farms with permanent crops and field crops were characterized by the highest crop diversity on arable land, while organic farms with dairy cows had the highest overall economic resilience, despite relatively low crop diversity on arable land. This phenomenon can be explained by the high proportion of permanent grasslands, which promoted feed self-sufficiency and the internal circulation of nutrients. The results indicate that in organic systems, the integration of crop and livestock production, based on permanent grassland, may be a more effective way to strengthen economic resilience than crop diversification on arable land alone.

The article is devoted to developing methodological approaches to multi-criteria resource optimization of technological solutions in Nature Use Projects, considering the growing shortage of water and energy resources, climate change, and post-war transformation of Ukraine’s agricultural sector. The need to transition from traditional technical and economic optimization models to integrated assessment approaches, which consider ecological, resource, and economic aspects of the project implementation effectiveness, is substantiated. The methodological basis of the study is a combination of Multi-Criteria Decision-Making and the Water-Energy-Food Nexus concept, enabling the necessary adaptive management and formalizing the process of project decision-making under multifactor uncertainty. A set of indicators of resource-ecological and economic efficiency is proposed, including indicators of productivity, weather and climate risk, resource use, environmental reliability, investment attractiveness, etc. A key feature of this approach is the transformation of resource-ecological indicators into a value form, ensuring their integration with economic indicators within a single optimization model. Based on a machine experiment for the conditions of the Kherson region, an assessment of the effectiveness of various irrigation regimes, which differ from the project irrigation regime in terms of watering and irrigation norms, in terms of their level of provision with water and energy resources, was carried out. It was determined that, under the studied conditions, in dry years (p = 70%), the permissible deficit threshold is approximately 30%, achieving a compromise between economic efficiency and environmental acceptability. Adaptive management of irrigation regimes has been shown to reduce the resource intensity of production without a significant loss of productivity. This creates a basis for revising outdated design standards, which focused on 100% satisfaction of water needs, in favor of adaptive models that account for the real resource potential of the territory. This approach transforms irrigation from a resource-intensive industry into a tool for sustainable territorial development, where the priority is the efficiency of each cubic meter of water and kilowatt-hour of energy used, rather than gross collection. It has been proven that the implementation of resource optimization as a basic principle of natural resource project management contributes to increasing the efficiency of natural capital use, minimizing ecological risks, and ensuring the sustainable development of the agricultural sector. The obtained results can be used to substantiate engineering solutions in projects for the restoration and modernization of water management and land reclamation systems in Ukraine. Full article

This study examines the network dynamics and shock transmission in the relationship between BRICS property market returns and geopolitical risk indicators, applying a time-varying parameter vector autoregression (TVP-VAR) method. The goal of this study is to investigate the dynamic connectedness and shock transmission between geopolitical risk and property returns in BRICS countries, with further insight into how geopolitical events lead to risk transmission. Using monthly data from February 2011 through June 2025 and isolating two tension periods after COVID-19, 2022 and 2024, we investigate geopolitical events and their shock transmissions. The findings illustrates the complexity of shifting geopolitical tensions and their effects on cross-market spillovers. That being, there exists moderate but economically significant systemic interconnectedness, with approximately half of the forecast error variance explained by cross-market shocks. This study further provides robust empirical evidence on the direct effects of geopolitical risk on BRICS property markets and their dynamic interconnectedness. Geopolitical risk especially originating from Russia and China, is found to be the key net transmitter of shocks to the region, whereas Brazil, India, and South Africa are the main net receivers. The results add to the evidence of regime-dependent spillovers, magnified by major geopolitical episodes such as the Russia–Ukraine war and the 2024 expansion of BRICS. Property markets are more vulnerable to geopolitical instability, showing their susceptibility to external risk spread. This study has implications for the sustainability and financial stability literature by emphasising the systemic nature of geopolitical risk in property markets, and it provides practical guidance for portfolio diversification, risk management and policy coordination in the BRICS bloc.

Under wartime conditions, conceptual approaches to organizing the education system are changing, and the means of achieving goals are being modified. All of this affects the development of infrastructural provision for the educational network and simultaneously requires adequate management. The state, as the main subject of social management, employs management theory and practice of competent (professional) business leadership. This approach not only allows it to survive but also to develop in the objectively existing competitive environment. It has been determined that the main elements of educational management (EM) organization include the quality of intellectual resources, analysis of internal and external environments, analysis, selection and implementation of educational system (ES) development strategies and evaluation and control of their execution. Attention is focused on forming an ecologically oriented society through the lens of knowledge transfer, with a focus on the irrational use of natural resources across various spheres of human activity, energy resource deficits, and sustainable development tasks in Ukraine. A central place in this process is assigned to organizing project activities and to forming an ecologically oriented worldview among future specialists trained by educational institutions at various levels and forms of ownership. The analysis of educational management (EM) models shows that the project-investment model remains relevant. Trends in quantitative indicators of EM and ecological projects in Eastern European countries have been analyzed, based on which conclusions have been formulated that reflect the current state of ecological education development and demonstrate existing changes, challenges, and prospects. A visualized flowchart of optimizing the organization of higher education through the prism of an environmentally friendly society has been developed, with four blocks highlighted: methodological, organizational, analytical, and resultant. It has been determined that knowledge transfer from universities to communities should become a priority in the state’s post-war reconstruction, ensuring the socio-economic development of regions, including strengthening Ukraine’s energy independence. The practical significance of the obtained results lies in developing recommendations for implementing the integration of educational management (new functions) and project activities in educational institutions, which can be used when forming their development strategies, establishing international partnerships in the educational sphere, as well as for developing state programs to support the development of Ukraine’s economic, ecological, and social policy.
