Our estimates indicate an 8.80%–8.94% decline in farmland values in ‘non-attainment’ counties in response to the enforcement of PM_2.5 standards, suggesting that the economic costs of the prescribed standards were capitalised into farmland values, particularly in regions with higher fertiliser use.

After combining a factor analysis with a fractional multilogit model accounting for factor loadings, the findings reveal four distinct profiles across the sample: a competitiveness-oriented approach; a focus on reducing health and environmental impacts; a risk management perspective; and an integrated vision combining multiple priorities. Being a farmer, advisor or researcher significantly influences the likelihood of belonging to one profile or another. However, close interactions between farmers, researchers, and advisors help bridge differences in priorities, fostering more closely aligned perspectives on crop protection strategies.

Using the Latent Class Stochastic Frontier Model (LCSFM), we studied the unobserved differences in technologies among 387 Colombian coffee farms in the Andes. Our findings show that farms adhering to sustainable standards achieved an efficiency rate of 95.68%, compared to 74.93% for farms heavily reliant on chemical pesticides.

Existing research has primarily focused on agriculture in high-income countries in Europe, North America and Australasia (Pannell et al. &lt;span&gt;2006&lt;/span&gt;; Knowler and Bradshaw &lt;span&gt;2007&lt;/span&gt;; Dessart et al. &lt;span&gt;2019&lt;/span&gt;) or low-income countries of Africa and Asia (Kafle &lt;span&gt;2010&lt;/span&gt;; Yokamo &lt;span&gt;2020&lt;/span&gt;; Ruzzante et al. &lt;span&gt;2021&lt;/span&gt;). On a number of dimensions, agriculture in the three countries studied here, Uruguay, Columbia and Mexico, sits in between the characteristics of agriculture in high-income and low-income countries (e.g., yields, mechanisation, farm size, labour use), although there is overlap.&lt;/p&gt;&lt;p&gt;Another area of relative neglect is research on the adoption of technologies and systems for livestock production. The great majority of existing studies focus on crop-production practices, including practices for increasing productivity and sustainability. The four papers included here address a wide variety of livestock production practices whose adoption has not previously been widely studied. They include controlled mating, artificial insemination, ovarian activity diagnosis, early weaning, various grazing strategies, pasture management, pasture improvement, adjustments to stocking rates, defined breeding periods, pregnancy diagnostics, post-calving nutrition, and adjusting the age of first pregnancy.&lt;/p&gt;&lt;p&gt;Most studies of practice adoption in agriculture have analysed cross-sectional data at a point in time part-way through the adoption process. Most have used regression techniques to identify independent variables that are correlated with adoption, ex post. In most cases, causality is assumed, but the research methods do not allow it to be tested.&lt;/p&gt;&lt;p&gt;The four papers presented here demonstrate that a wider range of approaches to studying adoption is possible and can be fruitful. Guerrero et al. (&lt;span&gt;2026&lt;/span&gt;) conduct a Discrete Choice Experiment with 274 Uruguayan cattle producers to understand their stated preferences for adopting four different packages of sustainable livestock management practices, as well as adoption of silvo-pastoral systems (combining trees with pasture and livestock on the same land).

Efforts to promote sustainable cattle production emphasize two key practices: sustainable pasture management (including rotational grazing systems) and ecologically appropriate stocking rates. However, their adoption varies widely because of institutional, economic, and biophysical constraints. This study applies a dual binary choice framework to examine the adoption decisions associated with these two practices and to assess whether they operate sequentially or independently. Results show that tenure security, measured through formal landownership, is strongly associated with the adoption of sustainable pasture management. In contrast, access to technical assistance is negatively associated with adoption, suggesting issues of program quality, targeting, or reverse causality. Older and more experienced producers are less likely to adopt, indicating path dependence. For stocking-rate decisions, rotational and alternating grazing systems exhibit lower probabilities of meeting sustainable thresholds, likely reflecting implementation challenges in extensive systems. Larger finishing areas also tend to be managed less sustainably, and descriptive evidence suggests that unsustainable stocking in our sample is more frequently associated with understocking than overstocking, with 239 producers (70%) below 1 animal per hectare. These findings illustrate how structural and institutional conditions, including those linked to conflict legacies, shape sustainability transitions in the Orinoquía and can inform more tailored policy interventions for frontier livestock regions.</p>","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"77 2","pages":"304-319"},"PeriodicalIF":4.2,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1477-9552.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148072162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One major source of these emissions is chemical fertilizer application. Introducing clover into grassland can mitigate emissions by reducing the need for chemical fertilizers. In this study, we conduct an information experiment with over 300 Irish dairy farmers to examine how information impacts their beliefs about clover adoption, and how this in turn influences subsequent intentions. Methodologically, we contribute to the literature by combining qualitative (i.e., open‐ended questions) and quantitative (i.e., point estimates) belief elicitation measures in our experimental design. This approach provides more detailed insights into farmers' beliefs, as it captures top‐of‐mind concerns without priming responses. Our qualitative belief elicitation reveals that after exposure to the information treatments, while most farmers did not change their opinions, some shifted from concerns such as ‘ <jats:italic>bloat</jats:italic> ’ and ‘ <jats:italic>difficult</jats:italic> ’ to terms like ‘ <jats:italic>reduction</jats:italic> ’ and ‘ <jats:italic>possible</jats:italic> ’. Our quantitative measures show that farmers underestimated clover's potential to reduce chemical fertilizer use. This finding is key for policymakers, as similar underestimations may apply to other GHG mitigation practices. Importantly, we provide causal evidence that information could reduce misperceptions. This highlights the need for strategies that positively shift beliefs to encourage more widespread uptake of climate change mitigation practices. Nonetheless, there was no meaningful impact of the updated beliefs on intentions, which underlines the complexity of adoption decisions.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"426 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
