Mexico: Migration, Borders, and Transnational Communities


This research delves into the repercussions of Mexico's presidential decree in late 2020, which imposed a ban on the human consumption of genetically modified (GM) corn by January 2024. In a trade dispute under the United States-Mexico-Canada Agreement (USMCA), the decree has sparked tensions between Mexico and the United States, particularly concerning the disruption of GM corn exports. Beyond trade dynamics, the study aims to address the broader impact on Mexico's food security landscape, exploring the intricate connections between the ban and various factors, including agricultural practices, economic implications, and shifts in the corn market dynamics. This research seeks to bridge the communication gap between policymakers and agricultural stakeholders in Mexico and the United States, focusing on the input of smaller producers in Oaxaca, Mexico. By addressing existing knowledge gaps, the research aims to provide a nuanced analysis of economic, agricultural, and cultural factors shaping the trajectory of food security in Mexico. The intention is to inform policymakers, agricultural stakeholders, and the broader community about the potential challenges and opportunities arising from Mexico's stance on GM corn and its implications for the nation's overall food security. The synthesis of findings suggests that the ban on genetically modified seeds has the potential to bolster food sovereignty in Mexico, safeguarding the food security of rural populations reliant on sustenance and traditional farming practices.
