We employ data from the Nigeria Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) from the years 2010, 2012, and 2015. Our findings show that although current high temperatures decrease crop yields, the overall agricultural output value is not affected by high temperatures, primarily due to increments in the area under cultivation. Our analysis also reveals that farmers re-allocate farm inputs in the face of high temperatures. Specifically, farmers shift from productivity boosting inputs, like fertilizers, to protective measures such as pesticides. This is accompanied by a greater dependence on hired labor after experiencing high temperatures in the previous year. Additionally, we find an increase in the adoption of mixed-cropping practices as a response to the high temperatures in the current season, indicating differential effects of high temperatures on crop production decisions. These insights highlight the importance of considering farm-level adaptive behaviors in policymaking, especially in initiatives aimed at increasing the use of specific inputs, as high temperatures can undermine such policy goals.</p>","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"54-76"},"PeriodicalIF":3.3,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12509","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706471","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}
{"title":"Who carries the burden of climate change? Heterogeneous impact of droughts in sub-Saharan Africa","authors":"Edouard Pignède","doi":"10.1111/ajae.12507","DOIUrl":"https://doi.org/10.1111/ajae.12507","url":null,"abstract":"<p>Droughts can dramatically affect economic activities, especially in developing countries where more than half the labor force is in the agricultural sector. This paper highlights the causal impact of drought on income inequality using a new methodology known as the quantile treatment effect on the treated under the copula stability assumption. This method generalizes the difference-in-differences framework to the entire distribution. The methodology is applied to a geo-referenced and nationally representative household survey of two sub-Saharan African countries: Ethiopia and Malawi. The results show that droughts worsen income inequality in both countries. Lower income quantiles are subject to a higher decrease in per capita income, up to 40% for the lowest income quantile. In contrast, higher income quantiles are largely unaffected or appear to benefit from the drought. These results are robust to several specifications and offer quantitative insights into how extreme weather conditions affect inequality dynamics in developing countries. Inequality formation is driven by differences in the ability to cope with droughts. The results show that wealthier households have a higher capacity to find alternative sources of income to prevent a welfare drop. In contrast, the most vulnerable households, particularly those that are low in assets, remote, or headed by women or older individuals, are most seriously harmed. Finally, consumption-smoothing behaviors and asset depletion strategies in middle income households are also observed.</p>","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 3","pages":"925-957"},"PeriodicalIF":4.2,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826658","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}
