This study evaluates the global land use and associated carbon implications of expanding Brazilian corn ethanol production using second crop corn. Using a global agricultural trade model, which explicitly represents second crop corn production in Brazil, this analysis examines scenarios regarding ethanol demand growth, corn supply elasticity, and trade constraints. Results show that increasing Brazilian ethanol production using second crop corn can moderately impact international prices, land-use, and greenhouse gas (GHG) emissions, especially when corn supply is highly elastic or double cropping intensifies. Under the limiting assumption of a perfectly elastic second-crop corn land response, our findings show minimal or even negative net land-use change. Focusing on land use, a life cycle analysis reveals that second crop corn ethanol can achieve lower or negative GHG emissions, primarily due to the use of feedstock grown on land already used in the same year (second crop), renewable process energy, and the substitution of soybean meal through corn co-products. These findings suggest that Brazilian second crop corn offers a low-carbon pathway for SAF production, contingent on preserving double-cropping systems and avoiding land-use change.

However, adoption rates of CSA practices remain uneven across genders due to disparities in access to resources, decision-making power, and socio-economic barriers. Similarly, while CSA practices are widely recognized for their potential benefits, the combined effects of using multiple practices to improve food security, nutrition, and poverty reduction remain poorly studied and not fully understood. This study analyzes data from four waves of the Nigeria General Household Survey, using fixed effects multivariate logit models and a panel endogenous switching regression framework to examine the factors influencing CSA adoption and its outcomes. The results show notable gender differences: male farmers are more likely to adopt organic manure and practice mixed cropping, while women focus more on improved seeds and combining organic and inorganic manure. Integrated CSA strategies, especially combining organic manure with mixed cropping, lead to significant gains in food security and reductions in multidimensional poverty. Nonetheless, organic/inorganic manure combinations are underused, mainly due to resource constraints and perceived inefficiencies. Addressing gender-specific barriers and maximizing the benefits of CSA practices can provide valuable insights for policymakers and practitioners.

These subsidies reduce costs for essential inputs, such as seeds, fertilizers, and equipment, alleviating financial pressure on farmers. While their positive effects on productivity and household income are well documented, less attention has been paid to their unintended consequences, such as their influence on child labor (CL) and educational outcomes, and more so to how these unintended effects manifest under opposing kinship traditions. This issue is particularly relevant in Malawi, where CL remains prevalent in rural areas, important, since kinship norms could offer differential protection to children. This study investigates the effects of the Farm Input Subsidy Program (FISP) on CL and its secondary effects on school attendance in two opposing patrilineal and matrilineal kinship systems in Malawi. Using data from the 2020 Multiple Indicator Cluster Survey (MICS), the study uses the Instrumental Variables approach (IV), with political clientelism as an instrument for the distribution of subsidy vouchers. We found that FISP increases CL for children in matrilineal kinship. However, the program had no similar impacts on patrilineal kinship. The results also reveal that FISP significantly increases school attendance, but only in matrilineal kinship.</p></div>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566391","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}

This paper investigates the changing scale structure of pig production and assesses both static efficiency and dynamic total factor productivity (TFP) for farms of four sizes using panel data from 27 mainland provinces for the period 2010–2022. Static efficiency is estimated using an input-oriented Data Envelopment Analysis (DEA) model under variable returns to scale, specifically the Banker-Charnes-Cooper (BCC) specification, while dynamic productivity change is captured by the DEA-based Malmquist index and its decomposition. The findings reveal that average static technical efficiency remains high, with medium-sized farms slightly outperforming others. Large-scale farms suffered a transient dip under external shock conditions, but subsequently recovered, largely through gains in pure technical efficiency. On the dynamic side, TFP hovered around unity, with technological progress emerging as the dominant driver of efficiency improvement. Regionally, eastern coastal provinces leveraged technological advancement to enhance productivity, whereas central and western regions were held back by persistent high-input/low-conversion inefficiencies. The results suggest that enhancing technological capacity and management performance, combined with region-specific strategies supporting optimal scale development and technology diffusion, are key to narrowing regional gaps and promoting the high-quality, sustainable development of China's pig-farming industry.</p>","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"57 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.70105","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615040","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}

This study investigates the determinants of this phenomenon by examining the role of Regional Trade Policy Uncertainty (RTPU), with a particular focus on the impact of the China-ASEAN Free Trade Agreement (CAFTA). Emphasizing the pro-competitive effects of regional trade agreements (RTAs), we develop a theoretical framework grounded in a mathematical model and employed firm-level data from the Annual Survey of Industrial Firms and Chinese Customs Database for the period 2000–2013. The empirical results indicate that CAFTA significantly reduces RTPU, which in turn lowers firm markups by intensifying competition in export market and promoting economies of scale effects. These are more pronounced among smaller firms in the food manufacturing sector and producers of lower-quality agricultural goods. Furthermore, the reduction in RTPU enhances resource allocation efficiency within the agricultural export sector by narrowing the dispersion of markups across exporters. This paper contributes to understanding the “black box” of markup formation in agricultural export by identifying a novel mechanism—RTA-induced competition—that helps explain the persistently low markups of Chinese agricultural exporters. Our findings provide firm-level evidence on how RTAs foster regional competition, amplify the benefits of regional trade, and improve resource allocation efficiency.
