Howarth Bouis

Founding Director, HarvestPlus 
emeritus Fellow, IFPRI 

Howarth Bouis, a recipient in 2016 of the World Food Prize, pioneered the concept of biofortification in the early 1990s and founded HarvestPlus in 2003. He has devoted his career to turning this idea into a global movement that currently reaches more than 50 million people in smallholder farming families in low-income countries. He continues to actively champion biofortification and the work of HarvestPlus in the international agriculture and nutrition communities. Bouis received a bachelor’s degree in economics from Stanford University and a master’s degree and PhD from Stanford University's Food Research Institute. Prior to beginning his graduate studies, Bouis worked for three years as a volunteer in the Philippines with Volunteers in Asia. After receiving his PhD, Bouis was offered a postdoctoral position in 1982 in the Food Consumption and Nutrition Division of IFPRI to undertake a two-year research project on the Philippines. He subsequently worked as a Research Fellow and Senior Research Fellow in the same division. His research concentrated on understanding how economic factors affect food demand and nutrition outcomes, particularly in Asia. Insights gained during this research led him to propose the concept of biofortification. Bouis also chairs the Board of Trustees of the Micronutrient Forum.  In 2017, he was awarded a Doctor of Science, Honoris Causa, by the University of Greenwich. In 2018, Bouis was named a Nutrition Champion by the African Leaders for Nutrition, a joint initiative of the African Development Bank and the African Union to promote high-level engagement and advance the nutrition agenda. Bouis currently resides in the Philippines.
