Evidence on the adoption of sustainable agricultural practices in urbanizing areas is scarce and mostly based on cross-sectional data. Cross-sectional studies, however, cannot reflect the dynamics of urbanization and adoption. We use household panel data from 2017 and 2020 to analyze the adoption of sustainable agricultural practices among peri-urban farmers in Bangalore, India, a rapidly urbanizing region. We focus on practices for water and erosion management, integrated pest management and soil fertility management, and an integrated package of sustainable practices. Using random effects probit models with the Mundlak approach, we consider various factors besides urbanization, including exposure to weather variability, awareness of climate change, connection with institutional actors, and household and farm characteristics. Results show that urbanization, measured as changes in the percentage of built-up area, reduces the probability that farmers adopt sustainable agricultural practices. Like prior studies, we find that wealth indicators, market access, knowledge of climate change, and rainfall variability facilitate adoption. However, contact with institutional actors largely reduces farmers’ probability of adoption. Policies should promote the integration of sustainable farming technologies at the institutional level and in information and training programs to achieve sustainable intensification of peri-urban agriculture.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 2","pages":"167-198"},"PeriodicalIF":9.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cjag.12355","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140011455","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}

We investigate how household behavior changed during the COVID-19 crisis, documenting both food stockpiling and increased food waste. The econometric analysis relies on a control function approach to handle endogeneity. We decompose the effects of increased risk on waste during the crisis into two components: the direct effect reflecting household decisions conditional on food stock; and the indirect effect associated with induced adjustments in food stock. Both effects on food waste are found to be positive, reflecting difficulties households have in managing large food stocks. We present evidence that one percentage point increase in household stocks during a period of supply disruption contributed to a 0.055–0.297 percentage point increase in food waste across food categories.

Our results suggest that the implementation of this policy significantly increased annual corn production in Northeast China by 15.1%. We also observed a substitution pattern between corn and soybean cultivation in the treatment area, with a percentage point increase in the net soybean-to-corn profit ratio leading to a decrease in corn production by 0.023 percentage points. Overall, based on changes in crop patterns during the system reform, increased straw resulted in increased burning and the resulting consequence to the environment is a net pollution increase equivalent to 16.03%, 0.33%, and 3.64% of the smoke and dust, SO2, and NOX, respectively, from the industrial sector in the treatment provinces.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 2","pages":"131-148"},"PeriodicalIF":9.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139760618","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}

However, the availability of residues for biofuel production is uncertain, because farmers have the option to grow different crops and use the residues for alternative purposes, such as livestock bedding and feed, or leave them in the field to improve soil quality. Taking Canadian wheat straw supply as an example, we develop a dynamic programming model to investigate a farmer's wheat straw supply decision in response to different wheat straw and grain prices. Our model considers crop choices between wheat and canola in the context of disease risk, the trade-off between the immediate payoffs a farmer may receive from bailing and selling wheat straw, and the long-term adverse effects that removing wheat straw from the soil surface may have on wheat and canola yields. The results from this study provide insights into how farm-level supply decisions, in response to wheat straw price changes, affect soil quality dynamics and scale up to regional wheat straw supply for biofuel production. This information also has implications for land use change and the sustainability of feedstock supply for biofuels.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 3","pages":"285-307"},"PeriodicalIF":2.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cjag.12350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139760691","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}

Participants completed a food choice task selecting five snacks out of twenty healthy and unhealthy options in an online experiment. Prior to the food choice, we randomized whether adolescents were exposed to unhealthy food or non-food online advertisements. To induce experimental variation in adolescents’ emotions, they were assigned to watch two, two-minute film clips validated to elicit the targeted emotion. The online food advertisement did not significantly impact food choices, except that Black and Hispanic groups selected a higher share of calories from unhealthy foods. Participants in a negative emotional state selected more unhealthy sweet snacks. Finally, we find only weak evidence that a positive emotional state amplified the impact of food advertisements on the nutritional quality of food selection. Together, results suggest that while a negative emotional state drives food choices, this pattern occurs independently from food advertisement exposure.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 1","pages":"45-76"},"PeriodicalIF":9.0,"publicationDate":"2024-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cjag.12353","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139677814","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}

We review the impacts of agricultural insurance on climate adaptation and mitigation, identifying impacts on both the intensive and extensive margins of production. We consider five potential program modifications, including: (1) changes in producer insurance premiums in AgriInsurance for the adoption of practices that would decrease the actuarially fair insurance rate if they were properly incorporated in the calculation; (2) dedicated insurance products related to trials of specific BMPs; (3) adjustments to current programs to allow more whole-farm considerations and intercropping; (4) cross-compliance measures on AgriInvest tied to environmental education; and (5) reduced insurance coverage for unfavorable environmental practices. While the effects of these potential modifications remain uncertain, they will drive the data collection process necessary to ensure that Canada's BRM programs play an appropriate role in greenhouse-gas reducing BMP adoption and climate change adaptation and mitigation.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 3","pages":"309-324"},"PeriodicalIF":2.5,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cjag.12349","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142099935","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}

While prices initially decreased, the shutdowns of beef packing plants led to a large reduction in the supply of beef and a corresponding increase in the wholesale price with ramifications along the entire supply chain. This study examines the effect of COVID-19 on price transmission and price volatility in the Canadian beef supply chain using monthly farmgate, wholesale, and retail price data covering the period from July 2005 to February 2022. We find evidence indicating that COVID-19 affected long-run price transmission from farmgate and wholesale markets to the retail market. Specifically, we find that the pandemic resulted in a 94.42 and 81.48% decrease in price transmission from the farmgate and wholesale market, respectively, to the retail market, indicating that higher prices at the wholesale level were not being passed on to consumers to the same extent. In the short run, we find asymmetric price adjustments and both direct and indirect volatility spillovers among the three levels of markets, implying strong market interactions across the beef supply chain. Overall, our results suggest the resiliency of the Canadian beef sector to COVID-19 shocks.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"72 3","pages":"389-406"},"PeriodicalIF":2.5,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139560590","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}

BMP measures include reduced fertilizer application, cover crops, buffer strips, and the restoration of wetlands. Environmental SWAT model results feed into a spatial optimization procedure using two separate objective functions to distinguish between public BMP program implementation costs (PIC) on the one hand and farmers’ private pollution abatement costs (PAC) on the other hand. The latter account for the opportunity costs of land retirement and changing land productivity. PAC are initially lower than PIC but exceed the latter after 30% of the annual TP baseline load is eliminated. This suggests that under optimal conditions existing grant and incentive payments cover the economic costs farmers face up to a maximum of 30% of the baseline load reduction. Imposing further reductions of up to 40% results in a cost to farmers of almost $52 million per year. This is 45% higher than the optimal solution based on PIC and therefore not deemed incentive-compatible under the watershed's existing cost-sharing scheme.","PeriodicalId":55291,"journal":{"name":"Canadian Journal of Agricultural Economics-Revue Canadienne D Agroeconomie","volume":"71 3-4","pages":"329-353"},"PeriodicalIF":9.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cjag.12342","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138535937","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}
