White science and indigenous maize: the racial logics of the Green Revolution

Indigenous maize from Mexico has become crucial for a wave of contemporary agricultural development initiatives seeking to cultivate a ‘Green Revolution for Africa’. Plant breeders developing disease-resistant hybrid maize for Africa use cutting edge technologies like CRISPR-Cas9 to mine the genomes of maize collected in Mexico 75 years ago, during the Green Revolution’s earliest incarnation. Historicizing this transnational linkage, this paper argues that Green Revolution science appropriates indigenous maize through racial logics rooted in whiteness. In the 1940s, American scientists sent by the Rockefeller Foundation to improve Mexico’s agriculture negotiated their own racial subjectivity through their encounters with Mexico’s indigenous people. In the process, they constructed a racial hierarchy that equated whiteness with scientific superiority and indigeneity with underdevelopment. This racialization undergirded a maize program led by E.J. Wellhausen that collected and catalogued hundreds of varieties of Mexico’s maize – and then distributed them to American seed companies. Wellhausen’s seeds formed the genetic backbone for subsequent Green Revolution projects. The ‘white science’ he embodied expanded as the Revolution sought out nonwhite agriculture across the global South. Today, the Green Revolution’s racial logics are re-articulated along its geographical and technological frontier, as indigenous maize provides the seeds for the African Green Revolution.
