While the taro industry had collapsed entirely in Ghana, researchers of the Crop Research Institute of the Council for Scientific and Industrial Research (CSIR) have succeeded in reviving it by developing new taro varieties that meet the industry’s current challenges.
Those are four new varieties that offer high yields and are incredibly resistant to taro leaf blight —scientifically known as phytophthora colocasia. This is a highly infectious disease responsible for the extinction of the crop.
The West Africa Agricultural Productivity Program (WAAPP) supported the institute to find solutions to the collapse of the taro industry in Ghana,”
Says Dr. Ernest Baafi, cocoyam and taro breeder at the Crop Research Institute of CSIR.
So, in 2017, after rigorous testing, Ghana’s National Variety Release Committee recommended four taro varieties for government approval.
After this step, the four varieties finally had the country’s Seed Board’s approval to be made available to farmers.
The varieties are currently at the stage of dissemination throughout the country. For that purpose, the CSIR is working in collaboration with government authorities, including the Department of Agriculture.
“We have set up a multiplication field in each municipality, and these fields will help serve the farmers in the municipality,” explains Dr. Baafi.
Farmers have welcomed the varieties and, in some municipalities, the impatience of having them is growing.
“I can’t wait to get the new taro seeds to resume my taro cultivation,” says Mrs. Akosua-Sera, who is also in charge of the seed multiplication field of her municipality located in the suburb of Kumasi.
“I am happy that these new varieties will come and have a higher yield. This will allow me to have good income-generating activity and to take care of my family,” she says.

Indeed, the new taro varieties offer a yield that varies between 12 and 25 tons per hectare, while the old one hardly offered five tons per hectare and suffered, helplessly, the assaults of the taro leaf blight.
“We can say today that the taro industry is reviving in Ghana through the WAAPP,” says Dr. Baafi.
The new varieties developed by the CSIR in Ghana can be eaten boiled or cooked; others can be used to make the pastry, chips, etc.
The WAAPP is an initiative of the Economic Community of West African States. It has been funded by the World Bank. Under the technical coordination of CORAF, the initiative started in 2008 and ended in December 2019.
Other benefits of Taro
Has good amounts of various nutrients that people often don’t get enough of, such as fiber, potassium, magnesium and vitamins C and E (2Trusted Source). Taro root is a good source of fiber and many vitamins and minerals that the standard American diet frequently lacks.
- May Help Control Blood Sugar
Contains fiber and resistant starch, which both slow digestion and reduce blood sugar spikes after meals.
- May Reduce Your Risk of Heart Disease
Its root is high in fiber and resistant starch, which help lower cholesterol and reduce your risk of heart disease.
- May Offer Anticancer Properties
Contains polyphenols and antioxidants that may combat cancer growth and protect your body from oxidative stress. Yet, more research in this area is needed.
- May Help You Lose Weight
Due to its high fiber and resistant starch content, it may increase feelings of fullness, reduce overall calorie intake and increase fat burning, potentially leading to weight loss and reduced body fat.
- Good for Your Gut
The fiber and resistant starch are fermented by gut bacteria to form short-chain fatty acids, which may protect against colon cancer and inflammatory bowel disease.
- Versatile and Easy to Add to Your Diet
It has a smooth, starchy texture and mildly sweet taste. It can be cooked and enjoyed in both sweet and savory dishes. You should not eat raw taro root as it contains compounds that may cause a stinging or burning sensation in your mouth.
