Keep native maize as living national heritage

Keep native maize as living national heritage

Mexicans say Sin maíz, no hay país: without maize, there is no country. In March 2025 Congress ratified a constitutional amendment that names native corn as part of national identity and bans planting genetically modified maize in Mexico. The reform builds on decades of farmer and Indigenous defence of criollo varieties that breeders and communities still rely on for tortillas, tamales, and milpa fields.

Trade panels under the USMCA still allow most imported yellow corn for livestock feed. The amendment focuses on cultivation and biocultural protection at home, not a sudden end to cross-border grain. A 2021 executive goal to replace roughly 16 million tonnes of imports with homegrown maize was an ambition, not a finished programme: Mexico still imports on the order of 17 to 18 million tonnes a year.

What you can do

• Support a community seed bank or start a neighbourhood seed library that loans heirlooms and asks growers to return seed after harvest
• Buy criollo produce and garden surplus from fair-trade channels such as Traspatio Maya when you are in Yucatán
• Learn how constitutional reform frames maize as heritage (Business Standard summary, Paradigm Futures trade context)
• Document and share seeds from varieties that grow well in your climate, as small farmers in Mexico have done for millennia

How it works

National law now elevates native maize in Articles 4 and 27 while GM planting stays prohibited. Community action sits beside policy: seed libraries keep varieties circulating, milpa plots maintain diversity, and buyers who choose criollo maize help farmers keep landraces on the field instead of only in memory.

Why it matters

Mexico is a centre of origin for maize. Losing a local variety weakens the global food toolbox for drought, pests, and a changing climate. Protecting living seed is builder work: culture on the plate and biodiversity in the soil at the same time.
