The prediction was made during a recent AfS Live webinar featuring four public sector scientists who are using cutting edge tools to improve food security and agricultural sustainability in Ghana.
The country’s cowpea productivity has been generally very low, said Dr. John Eleblu, head of cowpea and soybean projects at the West African Center for Crop Improvement (WACCI). It has been stagnate for years, with diseases, pests and drought affecting the yield of small holder farmers. This has made farmers over-reliant on chemicals, which are expensive, bad for their health and labor intensive, he noted.
“My research focuses on developing cowpea varieties that can tolerate these environmental stresses, using a combination of tools such as conventional breeding, mutagenesis, tissue culture and genetic modification,” Eleblu continued. “This will ultimately contribute to yield improvement for smallholder farmers in Ghana.”
In addressing the issue of nutrition insecurity, Dr. Agyemang Danquah, head of the tomato genetics program at WACCI, spoke about his efforts to improve access to healthy and nutritious vegetables using innovative tools.

“Tomatoes are one of the widely consumed vegetables in Ghana, especially among smallholder families,” he said. “However, its production faces many challenges like bacterial wilt disease, which has caused a lot of farming families in the north to stop tomato cultivation. Similarly, there’s the issue of drought and extreme heat in these northern climates.” Due to these challenges, Ghana has relied heavily on importation from neighboring countries, leading to a 10-fold increase in costs, Agyemang said.
“We are developing varieties that can adapt to these challenges, using a traditional breeding approach which involves screening several germ plasms for specific traits and then making new crosses to generate new varieties,” he explained. “But this takes a lot of years to develop, which is why tools like gene editing will help us address these issues within a shorter time frame. We need new and improved tomato varieties to not only improve the income of small holder farmers, but also improve nutrition among consumers.”
Ofosu noted that while improved technology is good, the adoption of new crop varieties also requires a favorable policy environment. “Ghana has recognized the potentials of biotechnology and new plant breeding methods techniques to improve food and nutrition security in the country,” he said. “So, what we’ve been doing is to build a system where a state institution can understand the technology better to enable them implement policies that would facilitate technology uptake.”
“The future of Ghana depends on these policies, especially the biosafety law,” said Dr. Mavis Owusuaa, molecular biotechnologist at the University of Energy and Natural Resources (UENR). “Once the door is open to GM crops, food insecurity will be a thing of the past. We will be able to feed the population and export more food, which will go a long way in improving the economic lives of Ghanaians.”
Owusuaa also noted that given the number of projects ongoing in Ghana, “it is obvious that we are ready to embrace the gene revolution.” Scientists are also ready to support it, she said, and “the farmers are welcoming. All they want is a good product, and the scientists are ready to work. We only need the government’s support in terms of funding and policy to make Ghana a better place for everyone,” she concluded.
