In wet subtropical environments, perennial groundcovers are common in horticultural plantations to protect the soil from erosion. However, there has been little investigation into whether seeding annual cover crops into the perennial groundcovers provides additional soil services including carbon and nutrient cycling in these systems. To investigate this, farmer participatory field trials were conducted in commercial avocado, macadamia, and coffee plantations in the wet Australian subtropics. Cover crops were direct-seeded into existing inter-row groundcovers in winter (cool season cover crops), and into the same plots the following summer (warm season cover crops). Inter-row biomass was quantified at the end of winter and summer in the control (no cover crop) and cover crops treatments. Soil carbon and nutrient cycling parameters including hot water extractable carbon, water soluble carbon, autoclavable citrate-extractable protein and soil enzyme activities were quantified every two months from early spring (September) 2021 to late autumn (May) 2022. Seeded cover crops produced 500 to 800 kg ha⁻¹ more total inter-row biomass over winter at the avocado coffee sites, and 3000 kg ha⁻¹ biomass in summer at the coffee site. However, they had no effect on biomass production in either season at the macadamia site. Soil functional parameters changed with season (i.e., time of sampling), with few significant effects of cover crop treatments on soil function parameters across the three sits. Growing a highly productive annual summer cover crop at the coffee site led to suppression and death of perennial groundcovers, exposing bare soil in the inter-row by 3 weeks after termination of the summer cover crop. Annual cover crops seeded into existing perennial groundcovers in tree crop systems had few significant impacts on soil biological function over the 12-month period, and their integration needs careful management to avoid investment losses and exacerbating the risk of soil erosion on sloping lands in the wet subtropics.

Organic agriculture is a complex, knowledge-intensive system, deeply aligned with sustainability goals. While the field has seen promising growth and innovation, it still grapples with significant challenges, particularly in how knowledge is shared, applied, and supported structurally within sustainability-oriented frameworks. To fill this gap, a systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, screening publications from the Web of Science and Scopus databases. A total of 39 scientific studies were analysed using content analysis and a bibliometric methodological approach. Findings reveal a balanced geographical distribution of studies and a dominance of qualitative methodologies. While farmers, advisors, and researchers are frequently involved in data collection, broader stakeholder engagement is limited. Key actors—research institutions, advisory services, and sectoral organisations—emerge as central to driving innovation and enhancing farmers’ access to actionable knowledge. However, the analysis identifies three core challenges: tailoring knowledge and innovation to diverse farming contexts; strengthening the intermediary role of advisors to bridge science and practice; and integrating organic agriculture more explicitly within the frameworks of sustainability and agroecology. Future research should focus on improving participatory dissemination strategies and strengthening intermediary roles to advance sustainability-driven innovation in organic agriculture. Full article

Addressing the interconnected challenges of food security, climate change, and population growth requires innovative and adaptive approaches to sustainable agriculture. Agricultural best management practices (BMPs) provide a promising framework for enhancing resilience, improving resource efficiency, and promoting biodiversity. However, the effectiveness of BMPs’ implementation largely depends on their alignment with local environmental, social, and economic conditions. This study presents a novel methodology for selecting and implementing BMPs based on stakeholder preferences, ensuring solutions are contextually relevant and widely accepted. Developed within the European Commission-funded WATDEV project, this methodology integrates a bottom-up and top-down decision-making framework, incorporating the perspectives of farmers, policymakers, and experts. The approach has been tested in four East African countries: Kenya, Ethiopia, Sudan, and Egypt, demonstrating its adaptability across diverse agroecological settings. Through a structured assessment involving stakeholder engagement, data-driven BMP selection, and participatory decision support tools, the study identifies and prioritizes BMPs that optimize water use, soil conservation, and climate resilience. Findings highlight that community-driven BMP selection enhances adoption rates and ensures solutions are technically feasible, economically viable, and environmentally sustainable. The methodology provides a scalable blueprint for integrating stakeholder preferences into agricultural planning, offering valuable insights for policymakers, researchers, and practitioners working toward sustainable food systems in East Africa and beyond.

Optimising kid rearing is essential for sustainable dairy goat farming, yet validated parameters and practical benchmark data are lacking. This study aimed to develop and evaluate a set of key performance indicators (KPIs) for monitoring kid-rearing practices through a participatory approach. Researchers, veterinarians and five dairy goat farms participated developed a prototype set of KPIs covering birth, colostrum management, average daily gain (ADG), and mortality, which were stratified across four rearing phases: perinatal (first 48 h), postnatal (birth to weaning), postweaning (weaning to 12 weeks), and final rearing (12 weeks to mating). The set of KPIs was subsequently tested for its added value but also for its feasibility in practice on the five participating farms as proof of principle. On these farms, data were gathered over a six-month period (June 2020–January 2021), combining routine census data with on-farm records. Only three out of five farms returned complete datasets encompassing data from 715 kids. Results revealed significant variation in rearing outcomes across farms, particularly in birth weights and postweaning growth. Birth weight emerged as a key predictor for ADG, while differences in weaning strategies had the greatest impact on postweaning performance. Although the farmers acknowledged the added value of the developed KPIs, collection of these data during the kidding season was challenging and required further automation to simplify data collection on the farm. This study demonstrates the feasibility and value of individual-level data collection in dairy goat systems and underscores the need for practical tools to support routine monitoring and data-driven management.

Oil palm is one of the primary vegetable oil sources worldwide, including in Tanzania. Tanzania’s mean palm oil yield is 1.6 tons per hectare, far below the 6 to 8 tons per hectare reported elsewhere. This low oil yield is attributable to underdeveloped, unsustainable oil palm production systems and improvements, several biotic and abiotic stresses, and socio-economic and policy challenges that have yet to be systematically documented to guide large-scale production, breeding, and research support. The objectives of this study were to appraise oil palm production and improvement in Tanzania, focusing on constraints, opportunities, and farmers’ major preferences. A participatory rural appraisal study was conducted in Kigoma Region, in three selected districts. Data were collected from 392 oil palm farmers using semi-structured questionnaires and 54 focus group discussants. Data were subjected to statistical analyses to discern the variables and their significant associations using the Statistical Package for Social Science (SPSS Inc., 2020). About 98.5% of the participant farmers engage in oil palm production. Most respondent farmers predominantly cultivate the Dura oil palm type (97.4%), followed by Tenera (50%). The farmers’ major reported oil palm production constraints were an inadequate supply of improved planting materials (reported by 82.7% of respondents), poor access to credit (72.4%), a high cost of production inputs (59.4%), poor market access (56.4%), insect pests and diseases (53.6), and poor production technologies (45.4%). A chi-square analysis of farmers’ production constraints revealed that the unavailability of labor (X² = 41.181; p = 0.000); limited extension services (X² = 29.074; p = 0.000); and diseases and pests (X² = 19.582; p = 0.000) differed significantly across the study area. Additionally, the lack of fertilizers (X² = 14.218; p = 0.001); inappropriate technology and knowledge gaps (X² = 10.529; p = 0.005); and poor market access (X² = 6.621; p = 0.036) differed significantly across districts. A high oil yield (reported by 58.7% of the respondents), a high number of bunches per plant (40.5%), early maturity (37.2%), and tolerance to droughts (23%) and diseases and insect pests (18.9%) were the most preferred traits by farmers in oil palm varieties. Therefore, integrative and sustainable breeding oil palm for enhanced yields and farmers’ preferred traits will increase the adoption of newly improved varieties for local palm oil production, import substitution, and economic development in Tanzania.

Food production faces significant economic, social, and environmental challenges. The Principles for Responsible Investment in Agriculture (CFS-RAI), aligned with the Sustainable Development Goals (SDG), provide a framework for implementing actions and investments in sustainable food production. Farmers are the primary investors in their agricultural activities, playing a fundamental role in the sustainability of rural territories. This study aims to analyze the rural development innovation system implemented by the Fundación Casa Campesina Cayambe and its alignment with the CFS-RAI principles and SDG. Focusing on 129 women producing healthy food within the Kayambi people and adopting a mixed-methods approach, including participant observation, interviews, and focus groups, the research examines the integration of public institutions, academia, and civil society in promoting sustainable rural development. The findings indicate that key innovation processes include a participatory, community-based, and gender-sensitive microcredit system implemented by the Foundation. Additionally, the technical and scientific support provided by the Universidad Politécnica Salesiana enhances investment capacity and knowledge acquisition, strengthening both individual and collective capacities for food production and commercialization. The study concludes that a decentralized and coordinated cooperation system, involving multiple territorial stakeholders, fosters the economic autonomy of female producers while adhering to the principles of CFS-RAI and the SDG.

Traditional cereals, recognised for their adaptability, high nutritional value, and unique sensory characteristics, have largely been excluded from global food supply chains. Recent shifts in consumption patterns, particularly in urban areas, indicate a growing demand for high-quality bread, creating new opportunities for farmers interested in sustainable production techniques and traditional varieties. However, challenges such as seed availability, regulatory constraints, marketing strategies, and logistical barriers persist. This study, conducted within the framework of the CERTRA project—Development of Traditional Cereal Value Chains for Sustainable Food in Portugal—aims to enhance the traditional cereal value chain in Portugal by identifying key challenges and opportunities and proposing effective development strategies. The research employs a mixed-method approach, including documentary research, a SWOT analysis based on the scientific literature and stakeholder insights, and a case study methodology examining twelve successful European initiatives. The findings highlight strengths such as seed sovereignty, resilience under low-input farming, and market potential through certification and short food supply chains. However, weaknesses such as lower yields, mechanisation challenges, and seed access restrictions remain critical obstacles. Our analysis suggests that participatory breeding programs, farmer-led seed networks, and hybrid distribution models integrating direct sales, online platforms, and local partnerships can support the revitalisation of traditional cereals. Future research should focus on consumer preferences, branding strategies, and technological innovations that enhance processing efficiency while preserving the ecological and cultural value of traditional varieties.

Aridification in the U.S. Southwest has led to tension about conservation and land management strategy. Strain on multi-generational agricultural livelihoods and nearly 150-year-old Colorado River water adjudication necessitates solutions from transdisciplinary partnerships. In this study, farmers and ranchers in a small San Juan River headwater community of southwestern Colorado engaged in a participatory, convergent research study prioritizing local objectives and policy. Acknowledging the historic and sometimes perceived role of academic institutions as representing urban interests, our goal was to highlight how research can support rural governance. This process involved creating community partnerships, analyzing data, and supporting results distribution to the surveyed population through social media. The survey was designed to support a local waterway management plan. Survey results showed lack of water availability and climate changes were selected by producers as most negatively affecting their operations, and many were extremely interested in agroforestry methods and drought-resistant crop species. Statistical analysis identified that satisfaction with community resources was positively correlated with scale of production, satisfaction with irrigation equipment, and familiarity with water rights. We hope to contribute our framework of a convergent, place-based research design for wider applications in other regions to uncover solutions to resource challenges. Full article

Background: Current evaluation tools are inadequate for assessing the impact of small-scale interventions, such as farmer’s markets or community meal programs, on fruit and vegetable consumption. This study analyzes the pilot data of a novel tool designed to evaluate community-based programs’ impact on fruit and vegetable consumption. Our research addresses the gap in effective evaluation methods for dietary behaviors within underserved populations. Methods: The survey tool was developed through a participatory research approach involving interest holders and community members. We conducted a pilot survey across four community-based programs, validated the findings, and compared them against the data from the Behavioral Risk Factor Surveillance System. Results: This pilot survey demonstrated a high completion rate of 98.2%. Notably, 62.5% of respondents reported an increased consumption of fruits and vegetables since participating in the programs and cited cost, time, and accessibility as primary barriers to healthy eating. There is a strong, though not significant, correlation of 0.876 (p = 0.12) between the pilot data of prevalence of daily fruit and vegetable consumption and the national average. Conclusion: Our findings suggest the survey tool effectively captures dietary behaviors and the influence of community-based programs. Further research is required to enhance its applicability in diverse settings and extend robust impact evaluation methods for these programs. Full article

Digital technology has facilitated the transformation and upgrading of agriculture, profoundly altering production and marketing methods, especially in peri-urban agriculture. Taking the peri-urban agriculture of Guangzhou, China, as an example, this paper delves into the digital transformation of peri-urban agriculture through in-depth interviews, field research, and participatory observation via a qualitative research approach. It explores the relationship between agricultural producers and consumers and its urban–rural integration mechanism. The findings reveal that digital technology promotes the digitization of agricultural production management and the networking of agricultural product sales markets. It further reconstructs the relationship between agricultural production and consumption, transcending traditional geographical constraints and fostering a direct production–consumption community link. With the empowerment of digital technology, peri-urban agriculture integrates seamlessly with manufacturing, services, culture, and ecology, thereby enhancing its value-added role in the metropolis’ fringes and facilitating the integration of urban and rural industries. Moreover, digital technology has significantly bolstered the role of peri-urban agriculture as a pivotal link between urban and rural areas, expanding its spatial function beyond mere production to include consumption and leisure. This not only solidifies the connection between urban and rural food systems but fosters social integration through subject interaction, cultural exchange, and value exchange. This paper broadens the interdisciplinary field of agricultural economics and digital technology, promoting sustainable agricultural development. It also accelerates urban–rural integration and harmonious development, providing new impetus for increasing farmers’ incomes and driving rural economic growth. Full article

Groundwater depletion in arid regions poses a significant threat to agricultural sustainability and rural livelihoods. This study employs geospatial analysis and economic modeling to address groundwater depletion in the arid Barind region of Northwest Bangladesh, where 84% of the rural population depends on agriculture. Using remote sensing and GIS, we developed an elevation map revealing areas up to 60 m above sea level, exacerbating evaporation and aquifer dryness. Field data collected through Participatory Rural Appraisal tools showed farmers exhibiting “ignorant myopic” behavior, prioritizing short-term profits over resource conservation. To address this, an Increasing Block Tariff (IBT) water pricing model was developed, dividing water usage into three blocks based on irrigation hours: 1–275 h, 276–550 h, and 551+ h. The proposed IBT model significantly increases water prices across the three blocks: 117 BDT/hour for the first block (from current 100–110 BDT/hour), 120 BDT/hour for the second block, and 138 BDT/hour for the third block. A demand function (y = −0.1178x + 241.8) was formulated to evaluate the model’s impact. The results show potential reductions in groundwater consumption: 59 h in the first block, 26 h in the second block, and 158 h in the third block. These reductions align with the principles of integrated water resource management (IWRM): social equity, economic efficiency, and environmental integration. The model incorporates economic externalities (e.g., well lifting costs) and environmental externalities (e.g., crop pattern shifts), with total costs reaching 92,709,049 BDT for environmental factors. This research provides a framework for sustainable groundwater management in arid regions, potentially reducing overextraction while maintaining agricultural productivity. The proposed IBT model offers a locally driven solution to balance resource conservation with the livelihood needs of farming communities in the Barind tract. By combining remote sensing, GIS, and economic modeling, this research provides a framework for sustainable groundwater management in arid regions, demonstrating the power of geospatial technologies in addressing complex water resource challenges.

Farmers have a pivotal responsibility in soil conservation: they can either preserve or deplete it through their choices. The responsibility of agriculture increases when practised in delicate ecosystems, such as lagoonal ones. The Venetian Lagoon islands, which are increasingly subjected to natural and anthropic subsidence, occasional flooding events (acqua alta), and eustatic sea level rise, are constantly exposed to erosive processes that challenge farmers to play with their adaptive capability. This research was carried out on the islands of Sant’Erasmo and Vignole, the most representative of island agriculture in the Venetian Lagoon: they almost exclusively rely on agriculture, which is almost nil in the other islands. This empirical research aimed to explore farmers’ agricultural practices, perceptions of soil changes, and how they adapt to them. It was fundamental for this study that the field research involved direct human contact with farmers (through semi-structured interviews) for data collection and using qualitative methods for data analysis, integrating scientific and non-scientific forms of knowledge and actors. The final purpose was to demonstrate the sustainability (valued on the potential depletion or regeneration capability) of agricultural practices and adaptation strategies on a theoretical basis. Despite their polycultural landscape (maintained by low-input farming systems), escaped from the predominant landscape oversimplification, Sant’Erasmo and Vignole are also subjected to unsustainable agricultural practices, including heavy mechanisation and synthetic inputs. Coupled with natural soil salinity that is exacerbated by increasing drought periods, these practices can contribute to soil degradation and increased salinity. The reported adaptation strategies, such as zeroed, reduced, or more conscious use of machines, were guided by the need to reduce the negative impact of soil changes on productivity. Our research revealed some of them as sustainable and others as unsustainable (such as increasing irrigation to contrast soil salinity). Participatory action research is needed to support farmers in designing effective sustainable agricultural practices and adaptation strategies. Full article

In Eastern and Southern Africa (ESA), smallholder rain-fed systems are vital, yet they are challenged by land degradation, soil fertility decline, and climate risks. To address these challenges, crop diversification has been promoted as a potential pathway to enhance productivity, improve nutritional security, and offer a viable pathway out of poverty and hunger. This study explores crop diversification among 150 smallholder households in the Kasungu, Mchinji, and Lilongwe districts of Malawi, where the project Sustainable Intensification of Maize Legume Systems in East and Southern Africa (SIMLESA) has engaged the smallholder farmers in conservation agriculture (CA)-based sustainable intensification participatory research and development for seven years since 2010. This study used Simpson’s diversity index (SDI) to estimate crop diversification, and a multiple linear regression model (MLRM) to analyze how smallholder farmers’ socio-economic characteristics influence adoption. The findings show a prevalence of small farms of less than 1.5 hectares, with most farmers perceiving crop diversification as beneficial for soil fertility. Key adoption constraints include labor shortages and a lack of legume seeds. SIMLESA participants lead in crop rotations, with a 63% higher adoption rate, and show the highest crop diversity, with a 99% increase in farmers growing three crops and a 74% increase in those growing four crops compared to non-SIMLESA farmers. The SDI values were 0.39 for non-SIMLESA, 0.48 for SIMLESA neighbors, and 0.57 for SIMLESA participants. Access to NGO inputs, larger farm sizes, and participation in research programs were positively associated with diversification, while food insufficiency was negatively associated with its adoption. The study highlights the importance of integrating participatory research methods to promote development initiatives effectively. Full article

This study explores how an inclusive governance of “niche” innovations with family farmers enables or limits the realization of just transitions in family farming at different scales, from the local to the national levels. The research focuses on a case study in the Brunca region of Costa Rica, which has pioneered innovations for bean research with family farmers. The primary source of information for the study was in-depth interviews with relevant stakeholders. Secondary information comes from a desk review of the relevant policies and strategic documents from the relevant authorities. Lastly, a semi-scoping review was conducted to explore gender and intergenerational gaps in plant breeding, as well as potential conflicts between plant breeding and on-farm agro-diversity. The inclusive governance of bean research contributes to the realization of just-transition dimensions of justice, such as recognitional, procedural, and distributional justice, as a result of farmers’ engagement in participatory plant-breeding processes, and due to the coordination between different institutions at the local and national levels. Progress has been made in terms of the recognition and participation of farmers in research and in decision-making locally. The findings show interactions between the local and national scales, in terms of the commercialization of farmers’ seeds. However, the Costa Rican program for bean research struggles to engage family farmers in national decision-making processes and falls short of addressing equality and intergenerational issues. It also faces challenges in reaching a balance between short-term income generation and long-term conservation of agro-biodiversity on the farm. Fostering just transitions in family farming would require a greater inclusion of women and youth by the Costa Rican bean system. This implies allocating resources to increase their capacities and participation in bean research, as well as in decision-making at all levels. This is imperative and could be achieved if the government and relevant stakeholders align their strategic objectives and priorities to shorten gender and intergenerational gaps within the bean production system.

Ecological engineering is defined as the design of ecosystems for the benefit of human society and the environment. In Asia, the ecological engineering of rice fields by establishing vegetation on bunds/levees for natural enemies has recently gained traction; however, its success depends on farmers’ willingness to implement changes. We surveyed 291 rice farmers in four regions of the Philippines to assess their bund management practices and willingness to establish bund vegetation that restores rice regulatory ecosystem services for pest management. During pre- and post-open field day (OFD) interviews, we assessed farmers’ perceptions of ecological engineering practices and sought their advice concerning bund vegetation. Over 60% of the farmers grew crops or allowed weeds on their bunds. Vegetables were grown as a source of extra food or income, and flowers were grown for pest management. Among the remaining farmers, their willingness to try ecological engineering increased from 36 to 74% after the OFDs. Furthermore, after the OFDs, willing farmers increasingly (from 2.6 to 15%) cited pest management as a reason to grow vegetables on bunds, and farmers almost exclusively focused on growing vegetables rather than flowers to adapt the system. While 46.5% of farmers who grew vegetables on their bunds applied insecticides, only ca 20% indicated that they would do so after the OFDs, if needed. Farmers had differing opinions on how vegetables would be incorporated into their rice farms. This range of options could be encouraged wherever farmers recognize the potential harm from pesticides for biodiversity and the restoration value of a diversified farm habitat. Full article
