However, the extent to which these shocks co-occur depends on local contextual factors. To inform the prioritization of interventions aimed at mitigating compound risks and strengthening agrifood system resilience, this paper examines where, and to what extent, climate extremes, food price volatility, and conflict events overlap, in Northern Nigeria, a region characterized by a high concentration of major agricultural markets and sufficiently rich data to support long-panel analysis across multiple commodities. Using data from 52 retail agricultural markets between 2002 and 2023, we estimate 9680 local regressions that permutate over a breadth of variables and their combinations. In doing so, we relax the constraint on co-occurrence allowing the measure to vary across locations to capture local specificity. Results reveal significant co-occurrences of climate extremes (especially drought), food price volatility (especially in locally important commodities), and increased intensity of conflict in the study area. In specific hotspots, the estimated intensity of co-occurrence is up to five times higher than in other locations, indicating a substantial within-country heterogeneity in exposure to compound risks. Our findings suggest the need for localized evidence to guide the targeting of interventions and to identify priority locations for investigating the root cause of vulnerability to compound risks.</p>\u0000 </div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 5","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148785196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Nigeria, multiple local conflicts have arisen as a result of climate-related changes in coastal regions. This study investigates the impact of cooperatives and climate change adaptation on conflicts among artisanal fisherfolk in Nigeria. To capture climate change adaptation complexity, we employed the number of climate change adaptation strategies adopted as a count variable. We applied Endogenous Treatment Poisson Regression and Unconditional Quantile Regression models to analyze cross-sectional data collected from artisanal fisherfolk in the coastal area of Nigeria. Findings from this research revealed that non-fishing strategies are equally important as part of the climate change adaptation strategies with 43%, 22%, and 14% of the respondents adopting livelihood diversification, a community conflict resolution committee, and formation of local security outfits (vigilante), respectively. The results further showed that cooperatives play a significant role in increasing the number of climate change adaptation strategies adopted. Also, the study empirically established that cooperatives lessen the incidence, especially of the most severe conflicts among artisanal fisherfolk. Therefore, policy efforts should be geared towards strengthening and developing cooperative societies among artisanal fisherfolk in order to strengthen climate adaptation and reduce conflicts.</p>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 5","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.70135","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, empirical evidence about how heterogeneity across farm sizes is associated with the joint production of desirable outputs and undesirable by-products remains limited, preventing our understanding of technical and environmental efficiency. Using country-representative survey data on rice production in China from 2014 to 2018, we estimate farm-level technical and environmental efficiency by employing a by-production function combined with a stochastic meta-frontier approach, accounting for heterogeneous technology across farm sizes. Our findings reveal considerable room to improve both technical and environmental performance, and the extent of both differs markedly by farm size. Medium-sized farms (2–6.67 ha) exhibit the highest meta-frontier technical efficiency, whereas large farms (6.67–33.33 ha) achieve the highest meta-frontier environmental efficiency. The estimated shadow prices indicate that the mean marginal abatement cost of nitrogen pollution is 129.233 yuan/kg. We also identify a range of farm-scale factors, such as technical training, land consolidation, higher educational attainment, and cooperative membership, which are significantly associated with higher levels of technical and environmental efficiency in rice farming. Counterfactual simulations further indicate that combining farm-size-specific measures could enhance meta-frontier technical and environmental efficiency. In particular, cooperative participation is positively associated with technical and environmental performance among smallholders, while high-level education and technical training are more impactful at large farms. Land fragmentation is consistently associated with lower efficiency and wider technology gaps across farm sizes. Our findings underscore the importance of designing farm-size-specific policies and implementing integrated interventions in promoting sustainable agricultural development.</p>\u0000 </div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 5","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The empirical application concerned the 126 prefectures in the Yangtze River Basin for the period 2000–2020. The empirical findings indicated an upward trend, with an average environment-adjusted agricultural productivity growth rate of 0.213 during this period when spatial spillovers and agricultural undesirable output were considered, suggesting that agricultural productivity was increasing rapidly and at an accelerating pace.

Fungus-resistant grapevine varieties are less susceptible to fungal diseases, reducing fungicide use by up to 80%. However, their adoption remains limited, despite their economic and environmental advantages. We develop a bio-economic simulation model with a real options investment perspective to analyze farmers’ decisions to adopt resistant varieties, accounting for different risk factors (e.g., production, market, policy). We apply the model to the case of Swiss viticulture. Results indicate that in the short-term, adoption barriers persist for the majority of farmers, with replanting occurring only when favorable conditions are met, such as low discount rates, high disease pressure, and available price premia. Conversely, we find that in the long-term, as vines reach replacement age, resistant varieties are favored over traditional ones. Our findings further indicate that increases in disease pressure, for example, due to climate change, are likely to accelerate the early adoption of fungus-resistant varieties. We highlight potential avenues for improving current support for replanting in Switzerland, for example, through market access and information provision. By integrating risk and managerial flexibility into a dynamic, real options decision-making framework, this study provides new insights for designing effective policies to promote sustainable pest management in viticulture.</p>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 5","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.70132","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation findings reveal that the transition to large farms results in long-term welfare losses for employed smallholsers, as well as rural households as a whole. This outcome is attributed to a reversed income effect, whereby the initial employment gains gradually diminish as the scale of transition progresses. Conversely, urban consumers gain substantial welfare improvements owing to lower retail pork prices, which are driven by the credit advantages and technological innovations of large farms. Additionally, aggregate social welfare improves as consumer surplus outpaces smallholder welfare losses.
