Fighting Hunger in Africa: Gebisa Ejeta

Dr. Ejeta’s personal journey would lead him from a childhood in a one-room thatched hut in rural Ethiopia to the height of scientific acclaim as a distinguished professor, plant breeder, and geneticist at Purdue University. His work with sorghum, which is a staple in the diet of 500 million people living in sub-Saharan Africa, began in Ethiopia in the 1970s. Working in Sudan in the early 1980s, he developed Hageen Dura-1, the first ever commercial hybrid sorghum in Africa. This hybrid variety was tolerant to drought and out-yielded traditional varieties by up to 150 percent.

Dr. Ejeta next turned his attention to battling the scourge of Striga, a deadly parasitic weed which devastates farmers’ crops and severely limits food availability. Working with a colleague at Purdue University, he discovered the biochemical basis of Striga’s relationship with sorghum, and was able to produce many sorghum varieties resistant to both drought and Striga. In 1994, eight tons of Dr. Ejeta’s drought and Striga-resistant sorghum seeds were distributed to Eritrea, Ethiopia, Kenya, Mali, Mozambique, Niger, Rwanda, Senegal, Somalia, Sudan, Tanzania, and Zimbabwe. Yield increases were as much as four times the yield of local varieties, even in severe drought areas.
