Mary Oyiela Abukutsa-Onyango (born 20 February 1959) is a humanitarian and agricultural scientist from Kenya who specializes in olericulture, agronomy, plant physiology. Abukutsa-Onyango is a professor of horticulture at Jomo Kenyatta University of Agriculture and Technology whose work focuses on African indigenous food crops.Abukutsa Onyango has studied how African indigenous vegetables can be used to combat malnutrition in Africa while maintaining a secure form of revenue even during more challenging weather and climate.

She attended Ematsuli Primary School from 1966 to 1972 in Emuhya, Kenya. She later attended Bunyore Girls High School from 1973 to 1976 in Wekhomo, Kenya and Ng’iya Girls High School in 1977 in Ng’iya, Kenya. She obtained a Bachelors of Science in Agriculture in 1983 from the University of Nairobi. She received her Masters of Science in Agriculture in 1988 from the University of Nairobi. Finally, she received her Doctor of Philosophy in Olericulture, Plant Physiology and Nutrition in 1995 from Wye College, University of London.

Abukutsa-Onyango’s interest and appreciation of indigenous African vegetables was sparked by an allergy to animal proteins she had as a child. This led her to pursue a career in agriculture as she wanted to unravel the potential hidden in African indigenous vegetables. She has been involved in research of African indigenous vegetables since 1990 on an academic level and a practical level with farmers. She surveyed Kenya’s indigenous plants to investigate the viability of seeds used by farmers. Her research has changed and she focuses on the nutritional properties of vegetables. Her research has shown that amaranth greens, spider plant, and African nightshade contain substantial amounts of protein and iron and are rich in calcium, folate, and vitamins A,C, and E. The cooking of these vegetables as studied by Abukutsa-Onyango could help combat malnutrition in Africa as they provide necessary nutrients and proteins to those who cannot afford meat.

Abukutsa-Onyango is a member of the African Women in Agricultural Research and Development (AWARD) team, a program created to increase the skilled women demographic supporting Africa’s women farmers. With this profile, Abukutsa-Onyango has been able to influence Kenya’s policy-makers. For example, the Health Ministry has advised hospitals to use African indigenous vegetables in HIV patients’ diets.

Abukutsa-Onyango has published over 20 peer-reviewed scientific articles and now teaches as a professor of horticulture at Jomo Kenyatta University of Agriculture and Technology in Juja, Kenya.
