Iowa State University’s Seed Science Center is mourning the loss of Joseph (Joe) Cortes, retired Global Seed Program leader, who passed away Friday, August 22, after a long illness. His wife and colleague, Adelaida Harries, preceded him in death just days earlier. The two shared a lifelong dedication to advancing seed science and policy around the world.
Cortes built his career around the belief that farmers everywhere should have access to quality seed and science-based policies and regulations. Born in Colombia, he earned a bachelor’s degree in agricultural engineering from the National University of Colombia, a master’s degree from the University of Campinas in Brazil, and a Ph.D. in seed technology from Mississippi State University. Early in his career, he worked at the International Center for Tropical Agriculture (CIAT) as a research and training associate, supporting seed system development across Latin America.
In 1991, Cortes joined Iowa State University as the Global Seed Program Leader after working in Peru on a USAID-supported seed systems development project. Over more than two decades at ISU, he became a recognized leader in seed policy harmonization in Africa, Latin America, and Asia. His work helped establish frameworks for regional seed trade in SADC, ECOWAS and COMESA countries, opening markets and strengthening the seed industry for millions of farmers.
His leadership earned broad recognition. In 1999, the American Seed Trade Association honored him for his vision and impact in Latin America. A year later, the Central American Organization for Regional Plant and Animal Health recognized his technical leadership in seed policy harmonization. He co-developed policy frameworks, produced training manuals used worldwide and mentored professionals who continue to advance his mission.
Beyond his professional contributions, Cortes was admired for his humility, generosity, and steadfast belief that quality seed is central to global food security. His legacy lives on through the systems and policies he helped build and through the people and institutions he inspired.
As we grieve the loss of Cortes and Adelaida, we honor their shared commitment to strengthening agriculture, empowering farmers and advancing seed science. Their work leaves a lasting impact that will continue to shape seed systems for generations to come.
