This study presents a comparative analysis of the barriers, motivations, and social implications of conversion to organic farming in four European countries: Germany (Thuringia), the Czech Republic, Hungary, and Slovakia. Conducted within the ETICOF project (Education, Training and Innovations in Conversion to Organic Farming), the research draws on 80 in-depth interviews with 40 organic and 40 conventional farmers (10 from each country). It explores perceived and experienced obstacles to organic conversion, identifies transnational patterns, and examines the role of social engagement in this process. Both conventional and organic farmers identified bureaucratic complexity, insecure markets, limited processing capacity, and knowledge gaps as key barriers. Conventional farmers often emphasized yield decline, profitability risks, and saturated markets, frequently overestimating challenges compared to the actual experiences of organic farmers. Organic farmers reported administrative burdens and initial capacity constraints but highlighted adaptive strategies such as cooperation, diversification, and direct marketing to overcome obstacles. Climate change emerged as a growing concern in Hungary and Slovakia, where droughts and extreme weather exacerbate production risks. Cross-country comparison revealed that Germany’s mature institutional framework and advisory services reduced perceived risks, while in Hungary, volatile markets and climate conditions were major deterrents. Czech farmers stressed administrative burdens and yield decline, whereas Slovak farmers found that long-term marketing strategies and consumer demand mitigate challenges. Here we show, for the first time, how the concerns and motivations of conventional farmers diverge from the lived experiences of organic farmers, revealing new insights into how farmers perceive and navigate the transition process across diverse institutional and climatic contexts. The findings demonstrate that supporting knowledge exchange, simplifying administrative procedures, and investing in infrastructure and climate resilience are essential to facilitate conversion. Overall, this study confirms that organic conversion is not only an economic and technical process but also a socially embedded transformation towards sustainability.

The inclusion of organic and locally grown foods in school meal programs has recently gained attention with the focus on improving child nutrition, supporting local agriculture, and reducing the environmental impacts. This research examines the financial implications of replacing imported conventional apple shares with locally grown conventional and organic apples in Czech school meals for children aged 7–10 and 11–14. Using real cost data and typical meal compositions, several substitution scenarios were modeled, including full replacement of apples and partial (5% of the meal portion) inclusion of local organic apples. Findings revealed that even at the complete replacement of imported apples with local organic apples, the total meal price increased by a small percentage (1.67%–1.89%) depending on the age group. The introduction of 5% share of organic apples resulted in minimal cost increases (0.54%–1.27%). These results are contrary to the public assumption that local and organic food sourcing imposes unsustainable costs on public institutions. The results also provide a feasible pathway for stepwise school meal reform in the Czech Republic. The study confirmed that gradual integration of organic produce is cost-friendly and supports goals related to child nutrition, regional food nutrition, and environmental sustainability.

Conflicts between crop farmers and herdsmen in Nigeria have intensified in recent decades, posing a danger to agricultural sustainability, rural livelihoods, and food security. This study investigated coping strategies that arable crop farmers have adopted in Enugu State, Nigeria, against herders’ incursions. Data were collected through the use of a structured questionnaire. According to the result, herders’ activities, including crop destruction, assaults on women, and intimidation, have severely affected livelihoods, which has resulted in reduced income and declining productivity. In response, most farmers applied some measures such as fencing, group farming, and cultivating small plots near homesteads to avoid clashing with the marauding Fulani pastoralists. Among all the measures adopted by the farmers, results reveal that only collective strategies, such as group farming and cultivating small plots close to homesteads, were sustainable. The study pointed out the limited capacity of rural households to cope alone and suggested the need for government assistance, such as the provision of less expensive protective infrastructure and stronger community security arrangements. The study recommends that the government should ensure and employ conflict management strategies through empowering traditional institutions with delegated legislation to ameliorate further occurrences. The research contributes to the body of literature by revealing the farmers’ viewpoints and strategies within the broader discourse on farmer–herder conflicts in Nigeria.

Agroecology offers a transformative pathway toward sustainable food systems by integrating ecological, economic, and social dimensions of farming. While its conceptual and policy foundations are increasingly recognized in European Union (EU) strategies, the practical adoption of agroecological principles at the farm level remains uneven, particularly in socio-economically peripheral Member States. This article investigates the enabling and constraining factors of agroecological uptake in three EU countries—Czech Republic, Hungary, and Portugal, using a mixed qualitative approach that combined literature review, policy mapping, and 42 in-depth farmer interviews conducted in 2020–2021. Data were analyzed through a shared coding framework, iterative team discussions, and a standardized comparative matrix to ensure cross-country validity. The results reveal shared barriers, including limited institutional coordination, subsidy dependency, and structural land inequalities, alongside country-specific dynamics such as farmer-to-farmer learning in Portugal, family-farm identity in Czechia, and trust-based advisory relations in Hungary. The findings underscore that systemic constraints, rather than conceptual gaps, impede agroecological transitions, and highlight the need for context-sensitive policy instruments, advisory reforms, and training programs aligned with agroecological principles. The paper contributes to the literature by providing empirical insight into farmer attitudes and practices in Central and Southern Europe and by offering actionable recommendations for designing policies and training.

Foodwaste (hereinafter, FW) is the most voluminous solid waste and its amount is growing rapidly all over the world. The turning of FW into biogas via anaerobic fermentation is widely recognized as an environmentally responsible and economically reasonable option. Based on the knowledge obtained from agricultural biogas stations, the current methods of FW fermentation management are based on balancing the ratio of total carbon and nitrogen. However, it was repeatedly and independently reported that the stability of this process is low, resulting in many concessions in terms of prolonged hydraulic retention time or reduced biogas yield. Hence, biochemical as well as economic performance of the process is balanced by mixing of FW with agricultural residues. FW samples of various origin were collected and biochemically analyzed. The data indicate that FW originating from homes and luxury restaurants tends to be lignocellulose-based, whereas the levels of crude fiber (25% up to 27%) are higher than those from agricultural feedstock (18%). In contrast, FW from school canteens and inexpensive restaurants tends to be starch-based with high levels of amyloids (21% up to 23%) and fat (5% up to 7%). A novel method better reflecting the bioavailability of carbon and nitrogen to anaerobic consortia is proposed. It is demonstrated that the previous optimization methods could somehow reflect the availability of nutrients in agricultural feedstock, as carbonaceous and nitrogen sources are relatively equally biodegradable. Nevertheless, the biodegradability of FW is considerably different, which is why higher amounts of proteins and lipids lead to increased levels of ammonia and sulfide, resulting in an inhibitory effect on the metabolism of anaerobic consortia. Optimizing the anaerobic fermentation of FW by the new method outperforms the previous technique and makes it possible to process FW more intensively, or, more precisely, with higher profitability and lower proportion of ballast agricultural feedstock.

Carrot cultivation in south-eastern Nigeria could reduce the need to transport carrots from northern regions. To explore this, a field experiment with three replications was carried out in Nsukka, south-eastern Nigeria, focusing on four carrot varieties (Carotte Touchon, Touchon Mega, Super Mega, and Touchon France) and three poultry manure rates (0, 10, and 20 t ha−1). The study revealed that Carotte Touchon had the highest root production (11.6 t ha−1) with 20 t ha−1 of manure, followed by 7.5 t ha−1 at 10 t ha−1, while Touchon Mega had the lowest root yield (1.4 t ha−1) in the control group. Proximate quality of carrots was mostly unaffected by the varieties, except for fat content. The study found significant variations in vitamins A, C, and E, phytochemicals (phytate, tannins, and oxalate), and minerals (Fe, Mg, Na, and K) among the varieties, although no impact on Zn and Ca was observed. This research suggests that carrots have substantial growth potential in south-eastern Nigeria, offering a solution to vitamin and mineral deficiencies prevalent in this area. Additionally, Carotte Touchon with either 20 t ha−1 or 10 t ha−1 of poultry manure is recommended for optimal carrot cultivation in this region.

The share of renewables is rising rapidly, especially in developed countries. Biogas production from purpose-grown phytomass is undergoing the fastest growth. The trend is linked to the production of vast amounts of fermentation residues. However, it has been repeatedly and independently reported that intensive or long-term application of fermentation residues into arable land changes soil structure, resulting in sharp degradation of its fertility. This is now compensated by more intense use of agrochemicals and additional agrotechnical operations such as biochar addition. However, the increased cost is beginning to threaten the economic sustainability of biogas production. Given the fact that the production of biogas from purpose-grown phytomass has become a strong pillar of the electricity grid, the threat to soil fertility may endanger its stability. The quality and quantity of soil organic matter (SOM) and in particular its stable organic fractions with ion-exchange properties (SOF) that determine soil fertility, or, more precisely, the transport of nutrients and their availability for plant growth, were investigated in detail. A novel, undemanding and quick method allowing the analysis and interpretation of SOM and its SOF was proposed and compared with conventional methods. It was confirmed that the adaptation of the new method enables farmers to better choose organic and mineral fertilizers and corresponding agronomic operations, so the soil can provide higher yields and an increased water retention capacity (up to 7%), which results in improved water retention during extreme rainfalls or droughts, altogether lowering the cost of purpose-grown phytomass, or, more precisely, improving the economy of biogas production.

Drawing upon literature from both impact assessment of development projects and agricultural research, the aim of this article is to analyse the pilot testing of a new multi-dimensional assessment framework for defining and evaluating the societal impact of agricultural research and corresponding education. The research approach involves an action research effort of pilot testing in three case studies from three different countries. The framework assumes a systems view, understands impact as socially embedded, and adopts the concepts of contribution and productive interactions rather than cause-and-effect attribution. The emerging experiences include developing both project-specific and universal indicators; gauging impacts at different levels and sustainability dimensions; handling the issues of attribution and time frame; and the role of stakeholder involvement. The results have the potential to support the development of a new role for impact assessment, by enabling principal actors in research and higher education institutions to take responsibility for contributing to concrete and demonstrable sustainability changes in society.

The demand for agricultural products is growing and is resulting in significant environmental impacts due to the overuse of fertilizers (and pesticides in some cases). There is a continued need to find sustainable methods in agricultural systems without harming the environment. Regenerative agriculture can be considered as one of the best methods of sustainable agriculture. The aim of this comparative life cycle assessment (LCA) study was to quantify the environmental impacts associated with the production of silage maize at different doses of fertilizers and pesticides under conventional agriculture and without the use of fertilizers and pesticides under regenerative agriculture. The input data were obtained from the experimental fields and supplemented by background process databases of Ecoinvent, World Food Live Cycle Assessment Database (WFLCD), and the French database AGRIBALYSE. The results of the study were related to six midpoint impact categories: global warming, marine eutrophication, freshwater eutrophication, freshwater ecotoxicity, marine ecotoxicity, and terrestrial ecotoxicity. Although the variant of growing silage maize without the use of fertilizers and pesticides according to the principle of regenerative agriculture showed the lowest burden on the environment, the yields of the cultivated silage maize were 43–55% lower than those of the fertilized variants.

Wheat (Triticum aestivum L.) is a strategic agricultural crop that plays a significant role in maintaining national food security and sustainable economic development. Increasing technical performance considering lowering costs, energy, and environmental consequences are significant aims for wheat cultivation. For drylands, which cover approximately 41% of the world’s land surface, water stress has a considerable negative impact on crop output. The current study aimed to assess the environmental aspects of chemical fertilizer in combination with compost in dryland and irrigated winter wheat production systems through life cycle assessment (LCA). The cradle-to-farm gate was considered as the system boundary based on one tone of wheat yield and four strategies: D-C (dryland with compost), D (dryland without compost), I-C (irrigated with compost), and I (irrigated without compost). Based on the results, the highest and lowest amounts of wheat yield were related to the I-C and D strategies with 12.2 and 6.7 ton ha−1, respectively. The LCA result showed that the I strategy in comparison with other strategies had the highest negative impact on human health (49%), resources (59%), ecosystem quality (44%), and climate change (43%). However, the D-C strategy resulted in the lowest adverse effect of 6% on human health, 1% on resources, 10% on ecosystem quality, and 11% on climate change. Utilizing a combination of fertilizer and compost in dryland areas could ensure a higher yield of crops in addition to alleviating negative environmental indicators.

Sugar beet (Beta vulgaris L.) is a well-known sugar crop essential for supplying the global demand for sugar. Examining how different farming techniques affect the environment may help produce a high-quality crop with the least negative environmental effects. To this, the life cycle assessment (LCA) of biochar (B) and cattle manure (CM) applications at three different rates (5, 10, and 15 tons ha(-1)) compared with conventional chemical fertilization (CH) in the autumn and spring sugar beet crops has been studied. The system boundaries for LCA analysis were set from the cradle to the sugar factory gate. Based on the results, the highest amounts of root yield were obtained under CM10 and CM15 treatments with 24.5% and 23.2% increase in autumn cultivation and 34.8%, and 33.9% increase in spring cultivation, compared to CH. However, CM15 resulted in significantly lower sugar content (10.9%) than B5 (17%). Also, B utilization significantly reduced molasses content in sugar beet rather than CM in both cultivation periods. Further, biochar treatments (B5, B10, B15) significantly increased the white sugar yield in both cultivation times by 43.7%, 39.2%, and 36.1%, on average. Generally, the highest and the lowest global warming potential (GWP) were obtained from CM15 and B15 with 638.5 and 437.2 CO2-eq ton(-1) root/sugar yields, respectively. These findings validate the hypothesis that using biochar in sugar beet production could reduce greenhouse gas emissions while increasing the amount of white sugar produced.

In the agricultural sector, where factors like the type of agriculture, management techniques, and access to funding are critical, disadvantaged people face significant barriers to employment. This study investigated the effects of these factors, especially with regard to sustainability and social farming, on the employment of disadvantaged persons in the Czech Republic. We sent questionnaires to 2036 agricultural businesses within the Czech Republic, and the data we received were sorted and analyzed. There was a favorable relationship between farm size and employment chances. Disadvantaged people were more likely to be hired by large farms, especially those larger than 250 hectares. Furthermore, mixed-production farms were more capable of employing disadvantaged persons, unlike conventional farms, which reached their maximum employment levels at one, three, or six workers. Organic farming had a more even distribution, while biodynamic farming showed limited capacity to employ disadvantaged persons. Farms involved in fundraising had fewer farms but employed more disadvantaged persons (number of employees peaked at two, four, and six), while farms that did not engage in fundraising hired more disadvantaged individuals (peaked at one and three employees). The motivations for employing disadvantaged persons were primarily social concerns, as well as labor shortages and economic and innovative factors. These findings show the importance of agricultural enterprises using these factors to improve the social and economic well-being of disadvantaged persons.

Agriculture is vital to human life and economic development even though it may have a detrimental influence on soil quality. Agricultural activities can deteriorate the soil quality, endangers the ecosystem health and functioning, food safety, and human health. To resolve the problem of soil degradation, alternative soil conditioners such as wood ash are being explored for their potential to improve soil-plant systems. This study provides an overview of the production, properties, and effects of wood ash on soil properties, crop productivity, and environmental remediation. A comprehensive search of relevant databases was conducted in order to locate and assess original research publications on the use of wood ash in agricultural and environmental management. According to the findings, wood ash, a byproduct of burning wood, may improve the structure, water-holding capacity, nutrient availability, and buffering capacity of soil as well as other physico-chemical, and biological attributes of soil. Wood ash has also been shown to increase agricultural crop yields and help with the remediation of polluted regions. Wood ash treatment, however, has been linked to several adverse effects, such as increased trace element concentrations and altered microbial activity. The examination found that wood ash could be a promising material to be used as soil conditioner and an alternative supply of nutrients for agricultural soils, while, wood ash contributes to soil improvement and environmental remediation, highlighting its potential as a sustainable solution for addressing soil degradation and promoting environmental sustainability in agricultural systems.

The demand for wheat production is increasing and is associated with environmental effects. To sustain the increased demand, there is a need to find sustainable methods of wheat production. The choice of cropping system can significantly affect the environmental burden of agricultural production systems. This study presents the results of monitoring emission loads resulting from winter wheat cultivation under different cropping systems: organic unfertilized (ORG), organic fertilized (ORG-F), conventional unfertilized (CON), and conventional fertilized (CON-F). The system boundaries include all the processes from “cradle to farm gate” and the functional unit was 1 kg of wheat grain. The primary data were obtained from experimental field trials and secondary data from Ecoinvent v3.5, WFLDB, and Agri-footprint v5.0 databases. The results of this study are related to eight impact categories. The SimaPro 9.2.0.1 software and ReCiPe Midpoint (H) V1.13/Europe Recipe H were used for calculation. The results show that fertilized variants recorded higher environmental impacts compared to the unfertilized variants. The results indicate that ORG-F was more environmentally friendly compared to the CON-F variant at the expense of lower yields. Overall, ORG imposes the lowest environmental impact and is deemed to be more environmentally friendly.

This report presents the results of qualitative research done on social farms in Ireland, Germany, Czech Republic and the Netherlands and focuses on the beneficial elements of a farm environment for different target groups. The research was part of the Erasmus+ project SoFarTEAM.

Phenolic compounds, especially phenolic acids (PAs), are believed to be one of the major contributors to the antioxidant activity of cereal grains. This study determined and compared phenolic concentration, radical scavenging activities, individual PA concentrations of emmer cultivars, and breeding lines to common wheat in a three-year controlled field experiment under organic management. It was found that common wheat had the highest ability to scavenge DPPH radicals (51.7%), followed by emmer Farvento (35.4%). DPPH scavenging activity of bound phenolic extracts was higher compared to free ones. Total phenolic concentration was the highest for common wheat (1902.6 µg FAE g−1 DM) compared to the highest level of all emmer cultivars—Farvento (1668.3 µg FAE g−1 DM). The highest PAs concentration was determined for emmer Farvento (431.3 µg g−1 DM) and breeding line PN 4-41 (424.5 µg g−1 DM). Free PAs concentration was the lowest for common wheat (29.5 µg g−1 DM). The dominant free PA was ferulic (66.3%), followed by syringic (11.7%), sinapic (7.4%), p-hydroxybenzoic (5.3%), salicylic (3.8%), p-coumaric (3.6%), and caffeic (2.1%). Bound ferulic acid accounted for 94.0% of total bound PAs, followed by p-coumaric (2.8%), p-hydroxybenzoic (0.8%), syringic (0.8%), caffeic (0.6%), sinapic (0.6%), and salicylic (0.4%). Emmer cultivar Farvento was distinguished by the highest concentration of individual free and bound forms of PAs. Effect of growing year was more evident on the concentration of free PAs compared to bound PAs. Extremely dry and hot weather during maturity stages has a negative impact on analysed free and bound PAs.

The aims of this study were to evaluate and compare the radical scavenging activities (DPPH), phenolic concentrations and concentrations of selected phenolic acids (PAs) of spelt cultivars and breeding lines with common wheat in a three-year controlled field experiment under conditions of organic farming. No significant variations were observed in the total and free DPPH of Altgold, Ebners Rotkorn, Ostro and PN-1-36 with common wheat. The total DPPH ranged from 52.13% to the lowest value of 44.01% in Franckenkorn. Total, free and bound phenolic concentrations were the highest for common wheat (1902.55 µg FAE g−1 DM of total), while all spelt cultivars achieved significantly lower values (from 1434.94 µg FAE g−1 DM in Franckenkorn to 1650.22 µg FAE g−1 DM in Ebners Rotkorn). Bound phenolic compounds represented 86.3% of the total ones. An extremely dry and warm ripening period had a negative impact on the synthesis of phenolic compounds. The highest concentration of total PAs was observed in spelt Ebners Rotkorn (681.75 µg g−1 DM) and the lowest in common wheat (396.05 µg g−1 DM). The total share of free and bound PAs was 5.7% and 74.8%, respectively. The extremely dry and very warm grain filling period had a more evident negative impact on the concentration of free PAs compared to bound forms. The dominant free PA was ferulic (70.48%), followed by syringic (9.30%), p-HBA (5.59%), sinapic acid (5.40%), salicylic (4.18%), p-coumaric acid (3.22%) and caffeic acid (1.93%). Spelt cultivar Ebners Rotkorn was distinguished by the highest concentration of free and bound forms of PAs.
