Public institutions and private companies increasingly aim to shape agricultural landscapes by influencing farmer decisions. Farmer land-use decision-making is complex and highly dynamic, especially in tropical smallholder systems. The use of serious games has been proposed as a promising research approach to understand these processes. However, it is often unclear how land-use decisions in such simulated settings relate to real life. In this paper, we explore how decisions in games made by farmers relate to their real-life decisions. We draw on a case study in Madre de Dios, Peru, where we interviewed farmers to design a game representing key components of the local farming system and external interventions. The game was played during 20 sessions involving 103 farmers. This dataset enabled the first systematic comparison in land-use serious gaming between decisions made in a game and the same farmers’ documented real-life decisions. We explored the game’s credibility, salience, and legitimacy by comparing farmer decisions in the game, including deforestation, crop choice, and participation in support programs, with those made in real life. Results show significant relations between farmers’ realities and their game decisions. The degree to which farmers receive support in real life predicts their preference for support in the game, and crop choices in real life resemble those made in the game. Cooperative membership in real life is associated with less clearing of primary forest in the game, and governmental support with larger loans. Overall, farmers found the game to be a good representation of their reality, which allowed them to discuss complex land-use decisions. We conclude that serious games can be credible, salient, and legitimate tools to explore farmer decision-making around land use, allowing exploration of the impact of present and future interventions.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 6","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-026-01147-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet few studies have investigated the characteristics and underlying mechanisms of resilience responses to drought in these systems at a macro scale. To narrow this gap, this study establishes a novel disturbance–response-based framework using resilience curves to overcome limitations in static indicator-based assessments. County-level drought resilience across China’s ecologically fragile Loess Plateau was assessed using spatial autocorrelation analysis and Bayesian hierarchical modeling with irrigation-stratified random slopes to identify spatial patterns and their drivers. Results show that: (1) County-level drought resilience predominantly clusters within the moderate-to-high range (mean DRGP = 233.5), where high-resilience systems show lower drought sensitivity, and resilience-level differentials in yield loss scale exponentially with drought intensification; (2) Spatially, drought resilience manifests a steep west-to-east gradient. Hotspots concentrate in northwestern irrigation districts and southwestern alpine foothills, whereas coldspots prevail in the northeastern agro-pastoral ecotone. Significant positive spatial autocorrelation substantiates this pronounced spatial differentiation (Moran’s <i>I</i> = 0.50, <i>p</i> &lt; 0.01); (3) Irrigation infrastructure emerges as a core effect modifier, reversing the directional associations of nine out of eleven drivers. In irrigated districts, annual precipitation, mean temperature, soil organic carbon density, fertilizer application rate per unit area, cropland proportion, total power of agricultural machinery, and per capita disposable income of rural households are positively associated with drought resilience, whereas grassland proportion and cropland slope are negatively associated. These associations reverse in non-irrigated areas. These findings indicate that drought resilience follows irrigation-dependent pathways. Irrigation districts should pursue synergy-based intensification, whereas rainfed regions require damage-mitigation strategies and ecological buffers. These context-specific pathways provide theoretical and practical paradigms for climate-resilient agriculture in global drylands.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 5","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Globally, a “residue revolution” is underway, with substantial increases in the quantity and persistence of residues driven by the expansion and intensification of annual crop production systems, widespread adoption of conservation agriculture principles, and growing recognition of the system benefits gained through residue retention. However, crop residues also act as reservoirs for damaging fungal crop pathogens, allowing them to persist between seasons and initiate residue-borne disease epidemics via inoculum carryover. Current management relies heavily on in-season management via genetic resistance and chemical controls, rather than preventative strategies that address off-season inoculum carryover. Consequently, broadacre production systems are increasingly vulnerable, as pathogens adapt to overcome genetic and chemical controls, partly due to the large populations persisting on residues. Despite this growing risk, previous review articles have overwhelmingly focused on individual pathogens or in-season management, with limited examination of the universalities of residue-borne diseases with respect to off-season survival and reproduction on residues. Here, we review an interdisciplinary body of research to address this gap. We (i) summarize key aspects of residue-borne pathogen biology, including reproduction, survival, and dispersal; (ii) outline global trends in agriculture collectively driving residue-borne disease risk; (iii) evaluate current and emerging management strategies that target residue-borne pathogen inoculum using an integrated disease management pyramid, with emphasis on breaking the “brown bridge” of off-season inoculum carryover; (iv) highlight key social and economic barriers to the adoption and integration of these management strategies; and (v) outline future research and investment priorities for the development of sustainable, systems-integrated solutions. This review provides growers, agronomists, and researchers with a framework for managing crop residues to reduce residue-borne disease risk while preserving the agronomic and ecological benefits of crop residue retention.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 5","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-026-01146-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149150785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a comprehensive investigation of these systems, specifically regarding their role in enhancing climate resilience, is limited. This study addresses the gap by presenting a novel integrated framework that identifies, values and quantifies the ecosystem services (ES) of traditional agroforestry systems and use this information to develop a Climate Resilience Index (CRI). The framework was applied to traditional homegarden agroforestry systems situated across four distinct socio-ecological zones in the climate-vulnerable region in the foothills of the eastern Himalayas. Initially, using the PRISMA framework for the literature review combined with participatory and non-participatory field approaches, it identified 15 key ecosystem services provided by homegarden agroforestry systems in the study region. A perception-based valuation of the identified ecosystem services, using a Likert scale-based method for 17 experts and 192 homegardeners, revealed that high crop diversity (4.4) and connection with communities (4.3), i.e., the indicators of supporting and cultural ecosystem services, respectively, were the most valued. Economic valuation showed that homegarden agroforestry systems provide an average annual value of USD 394.97 from provisioning services (market-based) and USD 178 from regulating services (biomass and soil carbon-based). Based on the ecosystem services, a novel CRI was developed. The CRI ranged between 0.88 (Protected Area) and 0.58 (Tea Estate) with an overall average score of 0.70 (<i>p </i>&lt; 0.001) in one-way ANOVA. In addition, the study introduces the application of the DPSIR framework to guide targeted policy interventions such as payment of ecosystem services, carbon credit scheme and Globally Important Agricultural Heritage Systems (GIAHS). This approach bridges the gap between scientific assessment and practical conservation and policy efforts to support the conservation of these time-tested, ancient, traditional and mixed farming agroforestry systems.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 5","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We interviewed 72 stakeholders and 178 households from 3 ethnic groups in 15 villages at 2 altitudes in northern Vietnam. We assessed farmers’ encounters and experimentation with introduced pumpkin types, and why they grew different types, defined by fruit shape and seed origin (self-saved or purchased), using thematic analysis. Farmers were grouped according to the dynamics of their choices. In Mai Son (700 m above sea level), four groups emerged: (i) farmers abandoning traditional types and only growing introduced types, (ii) farmers growing traditional and introduced types, (iii) farmers only growing traditional types after experimenting with introduced types, and (iv) farmers exclusively growing traditional types without trying introduced types. In Sa Pa (1600 m above sea level), the first group was absent. Farmers encountered and experimented with introduced types, resulting in adoption or eventual dis-adoption based on agronomic performance, market opportunities, and how introduced varieties fitted within broader livelihood systems co-influenced by market access, land and labor allocation, and food and feed needs. These factors operated differently across the two agro-ecologies. Traditional types were maintained if serving farmers’ needs, not for conservation. We showed for the first time how the dynamics of variety use were shaped by a range of changes, not static decisions. Simple adoption models are not useful for designing interventions that enhance the use of introduced pumpkins or the conservation of traditional pumpkins: variety choice proved to be an ongoing, dynamic, contextualized process. Interventions need to align with farmers’ shifting priorities and constraints to support innovation and in situ conservation.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 5","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-026-01138-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing crop diversification promises to improve system robustness by reducing and spreading out crops’ exposure to hazards, mitigating their vulnerability if exposed, and thus preserving their performance. Vegetable crops face severe biotic and abiotic stresses. In southern France, most medium-sized market-gardening farms still rely on specialized and lettuce-centered winter cropping systems, compromising long-term field potential and robustness. Many other species are agronomically feasible, but farmers face numerous impediments to significantly diversifying their winter systems. Providing results from agronomic field trials of contrasted diversification options can help overcome these obstacles. Few system experiments target market-gardening cropping systems, and even fewer evaluate strategies of crop diversification combined with other agroecological levers. This article presents the system experiment DIVEGFOOD, implemented in the French Mediterranean region to assess three agroecological diversified cropping systems and a poorly diversified baseline. DIVEGFOOD provided an original assessment of connection between diversification levels and robustness of agroecological market-gardening systems. Diversified systems still tend to be exposed to biotic pressure and injuries to harvests, but less so than the baseline, and to be less exposed to non-optimal conditions. Their production was preserved or improved on average, although some trade-offs had to be accepted for agroeconomic outputs. As it involved complex agroecological systems, DIVEGFOOD illustrated how crop diversification design and assessment require time, trade-offs and a systemic approach. We discuss why this pluriannual system experiment is emblematic of agroecologists’ methodological challenge to design and test promising systems in consistent farming conditions, using relevant assessment and analysis methods. Systems design and outcomes are discussed beyond the single technical field level, highlighting the leeway that could be opened by better dialogue between production and supply chain stakeholders, to support the agroecological transition.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"46 5","pages":""},"PeriodicalIF":8.2,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-026-01144-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the effects of landscape-scale netting on bird assemblages and functional groups in unnetted organic apple orchards in southeastern France, distinguishing between nets enclosing single-row trees and nets covering whole orchards. Bird assemblages were surveyed in 29 orchards along a landscape gradient of netting coverage. The local density of extensive hedgerows was considered as a covariate due to its expected influence on bird assemblages. Landscape-scale netting had no significant effect on overall bird abundance and species richness. Insectivorous species showed a limited negative response to landscape-scale netting, being positively associated with the landscape-scale proportion of unnetted orchards but not with total orchard cover. Species-specific responses were detected: The Eurasian blackcap (<i>Sylvia atricapilla</i>) increased only with the area of unnetted orchards, whereas the Eurasian blackbird (<i>Turdus merula</i>) responded negatively to single-row netting. The other abundant species were unaffected. Extensively managed hedgerows had strong positive effects on bird assemblages, highlighting their importance in supporting bird communities in agricultural landscapes.

In China, rapeseed production is constrained by substantial yield gaps and limited potential for cropland expansion. Identifying sustainable strategies that enhance rapeseed yield while minimizing carbon emissions is therefore crucial. This study integrates 3853 farmer surveys, 45 field experiments, and multitemporal satellite images to assess the potential of sustainably increasing rapeseed oil production across the Yangtze River Basin by balancing yield gap closure and expansion into winter fallow land. Results show that the current average yield gap is 450.6 kg ha⁻¹ and winter fallow land suitable for rapeseed cultivation is 8.61 Mha. Under green management, appropriate reductions in fertilizer and pesticide inputs while expanding the cultivation area could decrease carbon emissions by approximately 10% compared to the conventional management baseline, without compromising total production. Crucially, multi-objective optimization shows that fully closing the yield gap is the superior strategy. It meets China’s 2050 rapeseed oil demand with a total rapeseed planting area of only 5.44 Mha, while minimizing total emissions to 15.26 Mt. Regionally, the double-cropping area of the middle reaches of the Yangtze River exhibited a recoverable yield gap exceeding 500 kg ha⁻¹, identifying it as the primary area for yield improvement, whereas green management reduced carbon footprints in the upper and lower reaches of the Yangtze River by 22% and 29%, respectively. This study introduces a novel approach by integrating yield gap closure, winter fallow land expansion, and multi-objective optimization at a regional scale. It reveals that optimized management to close yield gaps is more effective than expanding winter fallow land for boosting rapeseed oil production and reducing carbon emissions.
