IITA and Pairwise secure $3.8M to boost yam production through gene editing

An important staple crop in many countries, optimizing yam production will help narrow the widespread nutritional deficit in Africa.

Nairobi, Kenya: The International Institute of Tropical Agriculture (IITA), in partnership with Pairwise, a US-based technology company pioneering the application of gene editing in food and agriculture, is delighted to announce a grant of US$ 3,874,356 from the Bill & Melinda Gates Foundation. This grant will support the "Yam Optimized Architecture through Gene Editing (YOAGE)" project, an innovative project aimed at delivering novel genetic variation to yam (Dioscorea spp.) that improves plant architecture. The project goal is to reduce labor and environmental impact associated with traditional plant staking while also enabling mechanized farming in Nigeria, where yam is an important staple food crop.

The 4-year YOAGE project will focus on developing yam varieties with optimized growth characteristics, improving cultivation practices, and boosting productivity and profitability while collaborating with various stakeholders, including local farmers, agricultural experts, and policymakers. Yam is the second most important root and tuber crop in sub-Saharan Africa after cassava, with a production of about 75 million metric tons (FAO, 2021) and provides about 200 kilocalories daily to over 400 million people in the low-income and food-deficit countries of the tropics. Africa produces over 97% of the global yams, with Nigeria alone accounting for about 66% of the world's total (FAO, 2021). In West Africa, particularly in Nigeria, yam is not only a staple crop but also plays a central role as a traditional flagship crop deeply intertwined with societal norms, fulfilling various social and religious functions.
