We use remote sensing data on forest fires and remaining tree cover to estimate the effectiveness of a project targeted at reducing fire incidences in 12 protected forests in arid Burkina Faso. The project consisted of two components that were implemented in the villages surrounding the target forests: a campaign aimed at raising community awareness about the detrimental effects of forest fires, and a program to support establishing and maintaining forest fire prevention infrastructures. Using the synthetic control method, we find that the project resulted in an overall reduction of <math>\u0000 <mrow>\u0000 <mn>35</mn>\u0000 <mo>%</mo>\u0000 </mrow></math> in the number of days on which an average forest grid cell was detected to be on fire in the month of the year when fires tend to be most prevalent—November, at the very end of the agricultural season. This impact is, however, short lived (as the reduction only occurred in the November months in the first 4 years of the program), and the overall reduction in forest fire occurrences was not sufficiently large to result in a detectable increase in vegetation cover. We then try to uncover the underlying mechanisms to shed light on which of the project's components were effective to also learn how the program can be improved.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 5","pages":"1684-1713"},"PeriodicalIF":4.2,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12464","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140004065","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}

Bigelow, Kate Binzen Fuller","doi":"10.1111/ajae.12465","DOIUrl":"10.1111/ajae.12465","url":null,"abstract":"The Conservation Reserve Program (CRP) allows agricultural producers to temporarily remove environmentally sensitive farmland from production in exchange for a yearly rental payment. While enrolled in the CRP, land typically complies with standards for organic certification, which prohibit the use of synthetic pesticides and fertilizers for three years prior to harvest. In this paper, we study the extent to which recent participation in the CRP promotes organic certification. We do so by estimating the relationship between exiting CRP contracts and new organic certifications at the county level over the years 2011–2020. Our primary results are based on an instrumental variables estimator, where we use the number of expiring CRP contracts as an instrument for endogenous net-exiting CRP contracts. We find that the exit of land from the CRP leads to increases in organic adoption, and estimate a 0.029% increase in new organic operations in response to a 1% increase in net-exiting CRP contracts. By highlighting this important co-effect of the CRP, our analysis contributes to contemporary discussions exploring the long-term linkages between land conservation policies, organic agriculture, and other conservation practices.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 5","pages":"1745-1774"},"PeriodicalIF":4.2,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140010978","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}

Williams, Steven Zahniser","doi":"10.1111/ajae.12463","DOIUrl":"10.1111/ajae.12463","url":null,"abstract":"Since joining the North American Free Trade Agreement, Mexico has increased its meat production and exports and become more dependent on imported feedstuffs such as genetically engineered (GE) corn. Mexico recently banned the use of GE corn in corn-based foods and called for a gradual substitution away from the use of GE corn for other uses (e.g., feed). This paper considers how a complete ban on GE corn might affect Mexican households using a computable general equilibrium (CGE) model to simulate the impact over the medium run (5 years). Results indicate that Mexico decreases corn imports by 76.9% and increases corn production by 65.6%—an increase that would require 3.3 million hectares more land for corn. The policy leads to a 24.8% increase in Mexico's corn price and up to a 6% increase in the prices of other agricultural products. But Mexico might have difficulty shifting land to corn; as such, we consider an alternative scenario that restricts land movements. We find that impacts are further exacerbated in this scenario—for example, corn prices triple. Our final contribution is to pair these results with a compensating variation calculation based on the almost ideal demand system. We find that Mexican households would need to spend, on average, between 6.7 and 13.9% more on food, depending on the scenario, to compensate for the resulting price escalations. Ultimately, our results show that a move toward greater food sovereignty in Mexico is ultimately borne by consumers via higher food prices.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 3","pages":"1300-1325"},"PeriodicalIF":4.2,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139953781","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}

We implement a fully incentivized condition within a geographically dispersed sample of consumers in which bids for a Criollo steak elicited by a Becker-DeGroot-Marschak mechanism are realized with certainty and the products are priority shipped in dry-ice coolers. The fully incentivized condition is compared to between-subject random incentivized schemes, in which only a fraction of subjects realize their choices. We tested two treatments with a 10% probability framed as a percentage or an absolute number of subjects, one treatment with a 1% probability, and a purely hypothetical reference condition. The results reveal that between-subject random incentivized schemes with 10% and 1% payment probabilities are effective in eliciting valuations that are statistically indistinguishable from the fully incentivized scheme. In addition to finding insignificant statistical differences between 10% and 1% and the fully incentivized scheme, all incentivized conditions mitigate hypothetical bias, resulting in lower product valuations than the purely hypothetical condition. We contribute a novel methodological framework for conducting large-scale experiments with geographically diverse and representative subjects, increasing the external validity and producing reliable valuations while significantly reducing financial and logistic constraints.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 4","pages":"1435-1453"},"PeriodicalIF":4.2,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12460","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139953687","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}
