Understanding the trophic ecology of the European brown hare (Lepus europaeus) is essential for its conservation in intensifying agricultural landscapes. To explore dietary niches across habitats, sexes, and age groups, we applied stable isotope analysis of carbon (δ¹³C) and nitrogen (δ¹⁵N) in hair samples from 151 hares collected in Lithuania and Poland from 2023 to 2025. δ¹³C and δ¹⁵N values varied significantly by country and habitat, but not by sex or age. Lithuanian hares exhibited lower δ¹³C values and a wider isotopic niche, reflecting more diverse foraging in heterogeneous habitats. In contrast, Polish hares from uniform orchard landscapes showed higher δ¹³C enrichment and narrower isotopic ranges, indicating greater dietary specialization on cultivated plants. Temporal variation was minimal, and isotopic overlap among months and years was high. These results suggest that habitat heterogeneity, rather than demographic factors, drives dietary flexibility in L. europaeus. Thus, stable isotope analysis provides a powerful tool for linking agricultural land use with trophic niche breadth in farmland mammals. Promoting mixed cropping systems, permanent vegetation, and structurally diverse habitats could improve food quality and support the recovery of declining hare populations. Full article

The socio-economic transformations that occurred across Central Europe in the 1990s profoundly influenced spatial development, as reflected in changes in population density and land cover, particularly in mountainous regions. This study investigates the relationship between population dynamics and land cover changes in the Polish Carpathians during the 20-year period following 1989, i.e., a time of major political and economic transformation. The research was conducted using detailed data based on 36 variables for 2250 statistical units at the lowest administrative level, combined with GIS-based analyses and statistical modelling. Results show that population density increased in more than 75% of administrative units, although the magnitude and direction of change varied considerably, both vertically and horizontally. The strongest growth occurred in the northern part of the study area, in the Foothills while depopulation was observed at higher elevations and in the eastern parts of the region. Land cover changes affected about 90% of administrative units, with built-up and infrastructural areas expanding mainly at the expense of heterogeneous agricultural land. At the same time, forest and shrub vegetation increased due to agricultural abandonment and natural regeneration. Principal component and mixed-model analyses identified topography, settlement location, and transport accessibility as the most significant drivers linking population and land cover changes. The findings highlight the lasting influence of historical spatial structures and initial demographic patterns on present-day development ways, illustrating how post-socialist transformation and EU integration have reshaped population distribution and land use in mountainous regions.

The differences in the forms of land rent in Poland and Ukraine are due to the specifics of the historical development of agrarian relations, the level of institutional support, and the condition of the land market in each country. The basis for this substantive analysis was the literature on the subject, primarily concerning the issue of land rent from a historical and contemporary perspective. Relevant legal acts and statistical data characterizing agriculture in the analyzed countries were also used. The aim of the conducted research and analysis was to identify and characterize the types of land rent in Poland and Ukraine. It was found that there are similarities and differences in the occurrence and perception of land rent between the analyzed countries. Not all types of land rent identified in Polish agriculture occur in Ukraine. In addition, those identified in Ukrainian agriculture are not always reflected in the same way in Polish conditions. This is related, among other things, to the historical conditions of the established agricultural system and Ukraine’s remaining outside the European Union. The comparative analysis of land rent types in Poland and Ukraine indicates a shared economic nature but significant differences in the mechanisms of their formation and distribution. Future research on land rents in Poland and Ukraine should be supported by empirical research and comparative analysis of the specific effects of the existence of individual types of rents.

Most Polish commercial dairy farms have expanded their production in recent years through herd increases and milk yield improvements. This study investigates internal and external drivers shaping farmers’ decisions regarding the future scale of milk production on family farms in Poland. The analysis is based on two sources of data. The primary input comes from a survey conducted in 2025 among 549 commercial dairy farms. To situate individual responses within a broader structural context, accounting data from 444 farms that continuously reported to the Polish FADN between 2005 and 2022 were used. Although not central to the analysis, these data illustrate long-term sectoral developments, particularly herd enlargement and resource concentration. The survey demonstrated a diversity of drivers shaping decisions to expand or stabilise milk production in the next five years. Farmers’ individual characteristics play a central role. The farmer’s perceived health and work ability (5-year horizon), as well as the availability of a successor, strongly influence the willingness to expand or maintain milk production levels. Other important factors include tangible resources, organisational capacity, and financial strength, such as herd size, agricultural land area, and investment capacity. This highlights the role of production potential and farm adaptability. External conditions such as land access, lease prices, and the market environment are not decisive by themselves but provide the background against which farmers evaluate their options. The study confirms that no single factor drives changes in dairy farms. What matters most is how farmers configure and align their available resources with external circumstances. The ability to combine human, physical, and financial capital in a coherent and strategic way is essential for shaping production strategies and ensuring the continuity of farm operations.

Solid biomass (agro-residue) is the most important source of renewable energy. The accelerating impacts of climate change and global population growth contribute to air pollution through the use of fossil fuels. These processes increase the demand for energy. The European Union has adopted a climate action plan to address the above challenges. The main aim of this study was to assess the economic performance of the producers of biomass for energy generation in Poland. The detailed objectives were to determine land resources in the studied agricultural farms and to determine the value of fixed and current assets in the analyzed farms. We used questionnaires as the main method to collect data. Purposive sampling was used to choose the farms. We conducted various tests to analyze the revenues from biomass sales and their normality, such as the Dornik–Hansen test, the Shapiro–Wilk test, the Liliefors test, and the Jargue–Berra statistical test. Moreover, we conducted regression analysis to find factors that are the basis for the economic performance (incomes) of farms that sell biomass. Results: This study demonstrated that biomass sales had a minor impact on the performance of agricultural farms, but they enabled farmers to maintain their position on the market. The economic analysis was carried out on a representative group of Polish agricultural farms, taking into account fixed and current assets, land use, production structure, and employment. The findings indicate that a higher income from biomass sales was generally associated with better economic results per farm and per employee, although not always per hectare of land. This suggests that capital intensity and strategic resource management play a crucial role in the profitability of bioenergy-oriented agricultural production. Conclusions: We concluded that biomass sales had a negligible influence on farm income. But a small income from biomass sales could affect a farm’s economic viability. Full article

Income level is a key indicator of the standard of living and the economic efficiency of undertaken activities. This paper aims to evaluate the earnings of Polish dairy farmers compared to those in other economic sectors between 2005 and 2022. The analysis covered 1688 family-run farms that participated continuously in the FADN system throughout the study period, with particular emphasis on farms that expanded their dairy cow herds. The remuneration for the labour of farmers and their families was estimated ex post by subtracting the opportunity costs of owned land and capital from farm income. The alternative cost of engaging one’s own land was determined on the basis of actual rental prices for farmland occurring in the surveyed farm groups in the years analysed. This information is collected in the FADN system from which the studied group of farms was drawn. The basis for determining the alternative cost of involvement of own capital was the average interest rates on deposits for households, concluded for a period of 6 months to 1 year inclusive, reported by the National Bank of Poland. The analysed population was divided into seven groups based on the number of dairy cows maintained. The analysis focused on two three-year reference periods: 2005–2007 and 2020–2022. The results were compared with average salaries and wages in non-agricultural sectors of the economy. Structural changes in agriculture, increased productivity, and the expansion of production scale in dairy farms indicate a growing professionalisation of the sector. The rise in farm incomes during the analysed period contributed to a significant increase in the remuneration for farmers’ and their families’ labour. The highest growth in remuneration was observed among farms with the greatest production potential and scale. While in 2005–2007 the remuneration for labour in dairy farms was lower than in non-agricultural sectors, this situation changed in 2020–2022. During this latter period, the average remuneration for labour on dairy farms slightly exceeded the average salary and wages in other sectors of the economy. Full article

The peculiarity of the wastewater produced in Polish dairies stems from the frequency and specific technology of cottage cheese production. The aim of this study was to determine the water consumption and the quantity and quality of wastewater and sewage sludge discharged from Polish dairies based on the size of the plant and the production profile of the plant to characterize the wastewater treatment plants (WWTPs). Data were collected from eighteen dairies. Most of them have their own WWTP. Water consumption ranged from 1.5 litres (L) of water per litre of milk processed to 3.71 L/L. The specific volume of wastewater ranged from 1.18 to 5.78 L per L of milk processed. The raw wastewater concentrations were comparable to those of dairy wastewater in other European countries. Despite the disposal of domestic wastewater in WWTPs, the results of the sanitary examinations of the sludge showed it was suitable for agricultural purposes. Its heavy metal also made it applicable on agricultural land. The ratio of the sludge to raw milk processing was between 0.137 and 7.927 kg of sludge per 100 L of milk processed. The amount of sludge produced per pollutant (BOD) load removed ranged from 0.404 to 18.895 kg/kg BOD_removed. Full article

The functioning and development of each economic entity requires the implementation of investments. In the case of farms in Poland, which are characterised by structural problems and a lack of capital, it is essential to undertake investment activities of a modern nature. The main objective of this research was to assess agricultural investments made in farms, considering the example of the Wielkopolska Voivodship in Poland, from the point of view of their impacts on changes in the economic efficiency of production factors. The data source was unpublished individual data from the agricultural accounting “Polish FADN” results for all farms in the Wielkopolska Voivodship who had continuously participated in the data collection system from 2009 to 2021. The project’s complexity was determined by measuring the scale of investments, relating the sum of investment expenditures to the average annual value of fixed assets (reduced by land value). Farmers endowed with a greater asset base had the ability to invest more comprehensively (i.e., in their most desirable scale regarding the value of possessed fixed assets) in a manner primarily concerning the value of fixed assets, especially the agricultural area, as a primary agricultural production factor. In terms of the effects of differentiating the scale of investment outlays (which was the aim of the study), a better initial state allowed farms to increase their area significantly, with an average annual rate of change of 3%. On the other hand, a lack of investment led to the decapitalisation of assets (−6.7% per year), which also concerned land sales (−1.5% per year). These research results indicate that not only does the undertaking of investments, in general, impact the development possibilities of farms—and, therefore, improvements in the resource situation of farms—but also the scale of investment (with respect to the value of possessed fixed assets).

Climatic conditions are the main factor influencing the suitability of agricultural land for crop production. Therefore, the evaluation of climate change impact on crop suitability using the best possible methods and data is needed for successful agricultural climate change adaptation. This study presents the application of a multi-criteria evaluation approach to assess climate suitability for maize production in Poland, for a baseline period (BL, 1981–2010) and two future periods 2041–2070 (2050s) and 2071–2100 (2080s) under two RCP (Representative Concentration Pathways) scenarios: RCP4.5 and RCP8.5. The analyses incorporated expert knowledge using the Analytical Hierarchy Process (AHP) into the evaluation of criteria weights. The results showed that maturity and frost stress were the most limiting factors in assessing the climatic suitability of maize cultivation in Poland, with 30% and 11% of Poland classified as marginally suitable or not suitable for maize cultivation, respectively. In the future climate, the area limited by maturity and frost stress factors is projected to decrease, while the area of water stress and heat stress is projected to increase. For 2050 climate projections, water stress limitation areas occupy 7% and 8% of Poland for RCP4.5 and RCP8.5, respectively, while for 2080 projections, the same areas occupy 12% and 32% of the country, respectively. By 2080, heat stress will become a limiting factor for maize cultivation; according to our analysis, 3% of the Polish area under RCP8.5 will be marginally suitable for maize cultivation because of heat stress. The overall analyses showed that most of Poland in the BL climate is in the high suitability class (62%) and 38% is moderately suitable for maize cultivation. This situation will improves until 2050, but will worsen in the 2080s under the RCP8.5 scenario. Under RCP8.5, by the end of the century (2080s), the highly suitable area will decrease to 47% and the moderately suitable area will increase to 53%. Full article

This study discusses the issue of determining the direction and strength of changes taking place in the structure of agricultural land in the mountain and foothill areas of the Carpathians in Poland in comparison with Slovakia, Romania and Ukraine. The most important financial institutional measures dedicated to the protection of the natural environment in Polish agriculture in the Areas facing Natural and other specific Constraints (ANCs) mountain and foothill in the first year of the CAP 2023–2027 were also established. Satellite data from 2001 to 2022 were used. The analyses used the land use classification MCD12Q1 provided by NASA and were made on the basis of satellite imagery collections from the MODIS sensor placed on two satellites: TERRA and AQUA. In EU countries, a decreasing trend in agricultural areas has been observed in areas below 350 m above sea level. In areas above 350 m, this trend weakened or even turned into an upward trend. Only in Ukraine was a different trend observed. It was found that in Poland, the degree of involvement of farmers from mountain and foothill areas in implementing financial institutional measures dedicated to protecting the natural environment during the study period was not satisfactory.

Agriculture is one of the key sectors of the economy, but it also generates many residues and waste that are only partially used (as, for example, feed, litter, and fertilizer). The resulting residues and waste can be valuable components for other sectors of the economy (e.g., energy), contributing to the implementation of a circular economy. The main aim of the research is to assess the diversity of the biomass potential from agricultural residues in the context of the level of organization of agricultural production and circular agriculture in Poland at the local level (314 counties). The level of organization of agricultural production was determined using the synthetic measure based on four variables (average farm size, number of tractors per farm, share of farms producing for the market, and the number of AWU per 100 ha of UAA). The potential of agricultural biomass was estimated on the basis of existing surpluses of straw, hay, energy crops grown on marginal lands, and residues from orchard maintenance. The data came from the General Agricultural Census conducted by the Polish Statistical Office in 2020. The conducted research showed that over 75% of counties are characterized by a high and medium level of organization of agricultural production. However, unused biomass resources from agricultural production residues are common (2/3 of counties are characterized by high and medium potential). There is a positive relationship between the level of biomass potential from agricultural residues and the level of organization of agricultural production at the local level in Poland, but the strength of this relationship is weak.

The study is part of the trend of searching for research methods to demonstrate changes in forest cover at the level of basic units of public administration with greater precision and accuracy. The purpose of the article is to present, for the first time, changes in forest cover of municipalities in Poland from 1990 to 2018 using CORINE Land Cover (CLC) data. The contributions of this study are threefold. Firstly, using GIS and CLC data (3.1. Forests), multivariate analyses of forest cover changes were carried out for 2481 municipalities for the CLC data collection years (1990, 2000, 2006, 2012, 2018), which showed the temporal and spatial dynamics of changes, with a predominance of deforestation in 1990–2000 and 2012–2018, and afforestation in 2000–2006 and 2006–2012. Secondly, the formal, legal and financial rationale for these changes was indicated. The increase in afforestation was a result of financial incentives under the National Program for Increasing Forest Cover and the EU’s Common Agricultural Policy (under Rural Development Programs—RDPs). Deforestation was related to a decrease in the supply of land for afforestation, the competitiveness of subsidies implemented under RDPs, and statutory liberalization of logging. Thirdly, the main discrepancies between the data obtained from CLC and from the public data collected by Statistics Poland (GUS) and the State Forests were indicated, which ranged from −32 kha to +310 kha, corresponding to percentage differences of 2.3% and 1.8%, respectively. This was mainly influenced by the differences in the complexity and updating of data collected for state and private forests, as well as delays in introducing changes to the land register by the public administration. This work contributes significantly to our understanding of the dynamics of forest cover changes in relation to the actual degree of forestation and deforestation, and the determinants of forest transformation in Polish municipalities, as well as demonstrating the new applicability of CLC data and their limitations related mainly to the generalization of forest cover area.

The research was motivated by the growing interest of scientists and practitioners in land consumption. It was assumed that the multifaceted and space–time analysis of the dynamics of land use change reveals agricultural and forest land conversion into artificial areas, and thus highlight the regions of high human pressure. To fulfill the research objective, the proprietary coefficient of admissible (maximal) land take (aLT) was used. This study, based on open, publicly available spatial and statistical data, presents agricultural and forest land losses in four periods (2005, 2010, 2015, 2020) in Polish provinces. The analysis reveals both the value and the trend of land take and indicates Mazowieckie and Małopolska as the provinces of the highest land take pace since 2005. In contrast, provinces such as Zachodnio-Pomorskie and Opolskie, located in the northwest and southwest of Poland, are characterized by small and decreasing losses of agricultural and forest land, prompting them to be classified as lower outliers. The paper concludes, in part, that admissible (maximal) land take (aLT) is a useful tool for monitoring land conversion and planning spatial development of any region in the world. Full article

The purpose of this paper was to examine the differences in using agricultural entrepreneurship support and how it relates to characteristics such as the agrarian structure, socioeconomic development level, and land use across the Polish territory. The analyses were carried out at the district (poviat) level which is an intermediate administrative unit. This study found that the decisions on co-financing the measures dedicated to non-agricultural economic activity heavily depended on the agrarian structure. The highest levels of activity were witnessed in districts where the agrarian structure was particularly fragmented. Full article

Changes in the agrarian structure are among the indicators of Polish agriculture’s adaptation to competition with the EU agriculture and therefore require a thorough examination. The purpose of this paper is to determine the scale, direction and level of diversification of Polish agricultural farm size structures in 2010–2020 by typological groups of voivodeships. The research was carried out on the basis of Statistics Poland (GUS) data on the number of farms by size groups for the years 2010 and 2020. The following farm size groups were analysed: up to 2 ha of agricultural land (AL), 2–5 ha, 5–10 ha, 10–20 ha, 20–50 ha and over 50 ha. Based on fuzzy classification, four typological groups were distinguished, comprising voivodeships with similar farm size structure. Then, changes in the structure of the typological groups and changes in the number of farms in absolute terms were presented. The structure of the typological groups changed only marginally, while changes in the number of farms in absolute terms were very significant. In all groups, a decrease in the total number of farms was observed, notably farms of up to 10 ha in size, as well as an increase in the number of farms larger than 20 ha, with the rate and scale of those changes varying regionally. The largest decrease in the number of farms was recorded for voivodeships with the most fragmented agrarian structure. Full article
