Efforts to improve agricultural sustainability have increasingly focused on enhancing productivity while minimizing environmental impact. In the Republic of Serbia, dairy farming remains a critical sector due to its dual role in food production and environmental pressure. This study aims to evaluate the technical and eco-efficiency of dairy farms in the Republic of Serbia using FADN data and the Stochastic Frontier Analysis (SFA) method. Specifically, the SFA methodology was applied, which enables a separate assessment of time-invariant and time-variant efficiency, with the aim of clearly identifying the factors that shape milk production in the Republic of Serbia. It was found that the technical efficiency for the 2015–2023 period was at a level of 58.7%, while the eco-efficiency was estimated to be 13.1%. Observing the relationship between the estimated technical and eco-efficiency, it can be concluded that they share similar mechanisms for improvement. In both cases, time-invariant inefficiency dominated, indicating that factors under the control of farms, such as the characteristics of agricultural producers and farms, play a key role in shaping production efficiency. In this context, adopting circular economy principles, such as nutrient recycling, the use of renewable energy, and optimized input utilization, offers an additional opportunity to enhance both economic and environmental performance.

The transition toward sustainable, resource-efficient production has become a key challenge for agri-food systems, particularly in emerging economies, where profitability and environmental goals must be balanced. This study aimed to examine the relationship between financial structure, macroeconomic conditions, and circular economy (CE) indicators in determining the profitability of Serbian agri-food enterprises. Using panel data for 625 firms from 2014 to 2021, a two-step system GMM model was applied to control for endogeneity and firm-specific effects. The results indicate that in agriculture, moderate leverage enhances profitability, while excessive debt reduces it. Recycling and efficiency-oriented circular practices have a positive and significant effect on financial performance, suggesting that resource-efficient management supports long-term profitability. In the food industry, profitability shows strong persistence but remains mainly driven by internal and economic factors, with CE indicators exerting weaker short-term effects. Robustness tests confirm the validity and stability of the estimates. Overall, the findings highlight that integrating circular economy principles into business strategies can contribute to both financial sustainability and more efficient resource use in the agri-food sector.

In recent years, Serbia has become increasingly popular as a tourism destination, attracting travelers from the surrounding region, as well as Europe and even distant locations. The environmental impact linked with tourism activities, specifically their carbon footprints, has gained growing attention as sustainability becomes an important factor when discussing the future of tourism. This research, which is based on the DEFRA and ADEME methodologies using the Greentripper tool, examines the significance of carbon footprint estimations for incoming tourism in Serbia from a scientific standpoint. By considering the emissions produced from transportation, accommodation, and on-site activities, the results of 1,431,394,511 kg CO2e offer valuable information about the extent of carbon emissions linked to tourism movements. The primary driver of this carbon footprint is transportation (80.2%), on-site activities (15.2%), and housing (4.6%). The per capita tourism carbon footprint is 670 kg CO2e, which is lower compared to the values derived using general data and carbon emissions on a worldwide basis, which amount to 759 kg CO2e. These findings are essential for comprehending the environmental sustainability of tourism operations. Furthermore, carbon footprint assessments play a crucial role as a tool for making informed decisions and implementing initiatives to reduce carbon emissions in the tourism business. This could involve selecting environmentally friendly modes of travel, advocating for sustainable hotel choices, or integrating carbon offsetting activities into vacation packages. In addition, carbon footprint assessments promote transparency and responsibility in the tourism industry.

In contemporary tourism, gastronomic offerings increasingly go beyond the boundaries of mere taste enjoyment, becoming an important element of the sustainable development of destinations. At the same time, food safety is gaining importance as a key aspect of the tourist experience and trust in a destination. The research was conducted in Serbia, focusing specifically on agritourism farm stays known for their local food production and sustainable hospitality practices. This study highlights the crucial link between local agricultural practices and tourists’ perceptions of food safety, positioning food safety as a key dimension of both sustainable gastronomy and rural development. The research was conducted on a sample of 650 tourists in farm stays, using a structured survey questionnaire, with data analysed through descriptive statistics, factor analysis, Pearson correlation, ANOVA, and multiple regression analysis. The results indicate that tourists highly value food safety, particularly in the context of local and traditional gastronomy, and that there is a significant correlation between the perception of food safety and the intention to revisit or recommend a destination. This study suggests that the integration of food safety standards into sustainable gastronomic practices is essential for enhancing competitiveness and building long-term trust among individuals of various sociodemographic profiles.

The transition toward sustainable and circular agricultural systems is increasingly important, yet evidence linking circularity and farm profitability in transition economies remains limited. This study examines the determinants of farm profitability in Serbia by combining micro-level structural and productivity indicators with a macro-level agro-eco efficiency measure, used here as a sector-wide ecological pressure indicator rather than a direct proxy for circular practices. Using a balanced Farm Accountancy Data Network (FADN) panel of 443 farms (2015–2022) across dairy, mixed, field crop, and fruit & wine sectors, dynamic panel estimators (difference and system Generalized Method of Moments-GMM) reveal strong sectoral heterogeneity. Asset turnover is the primary driver of profitability in field crops and perennial systems, while dairy farms benefit from scale and land productivity. Energy intensity consistently reduces profitability across all sectors. Agro-eco efficiency shows a negative effect in livestock-based systems, indicating higher sensitivity to macro-ecological pressures. These findings suggest that environmental and economic vulnerabilities differ across production systems, highlighting the need for sector-specific strategies aimed at improving resilience rather than inferring the profitability of circular technologies.

Climate change presents interconnected challenges to global agriculture, particularly within vulnerable regions, such as the Pannonian Biogeographical Area (PBA), which experiences extreme weather events. Traditional reductionist approaches have proven insufficient against complex issues such as increasing droughts, high temperatures, floods, and new pests and diseases. This review proposes and validates innovative systemic solutions to enhance climate resilience across identified critical key agricultural sectors: crop production, agroforestry, the water-food nexus, and cattle production. Utilizing a consistent model, four deep demonstration sites will be established in two sectors (Serbia and Hungary) to develop and test the proposed solutions. Multi-environment trials replicated across eight additional diverse European environments will provide a robust validation of performance under varied conditions, mimicking real-world agricultural complexities across Serbia, Croatia, Romania, and Czechia. This holistic, systems-thinking approach aims to create comprehensive strategies that build climate resilience, secure agricultural production, foster long-term sustainability within the PBA, and serve as a blueprint for broader European implementation.
