Ancient Maize v. Agribusiness: Why Colombia’s ‘Seed Guardians’ Are Fighting the Use of GM Crops
June 26, 2025 | Source: The Guardian | by Gabriela Barzallo
On a hillside farm in San Lorenzo, in the mountains of Colombia’s southern Nariño department, Aura Alina Domínguez presses maize seeds into the damp soil. Around her, farmers Alberto Gómez, José Castillo and Javier Castillo arrive with their selected seeds, stored in shigras – hand-woven shoulder bags – as has been done for generations.
In San Lorenzo, they call themselves “seed guardians” for their role in protecting this living heritage and passing it down the generations. “Each seed carries our grandparents’ story,” says Domínguez, arranging the dried cobs that hang from her rafters.
Domínguez, Gómez, and the Castillos are among the farmers supporting draft legislation, under review by the lower house of the Colombian parliament, that would ban genetically modified (GM) seeds, which they claim threaten their traditions, livelihoods and food sovereignty.
The initiative has the backing of Indigenous, peasant and environmental organisations, but faces opposition from agribusiness and sectors that support GM as a strategy for economic development.
