Despite its low water requirement in comparison to maize, relative drought-resistance and potential benefits for health and sustainable agriculture, sorghum has received little attention in comparison to other crops. However, the increasing impact of climate change calls for renewed exploration into sorghum as a crop for food and beverage.
Sorghum is the third most important cereal grain after maize and wheat, yet many South Africans don't know about the grain said UP’s Professor Riëtte de Kock, speaking during the National Research Foundation’s Science for Society Lecture.
Rapid urbanisation and rising incomes have caused extensive changes in diets, as people opt for convenience over health. Indigenous grains present healthier alternatives to high-energy, high-glycaemic index (GI) foods made from highly refined wheat and maize. Indigenous grains like sorghum present alternatives to reduce the risk of strong climatic conditions in Africa and the world. A lot of work has been done to identify the health-promoting properties of indigenous grains, but “more research is needed, particularly in human studies, to increase the knowledge base concerning the health benefits of legumes,” said Professor Gyebi Duodu of UP and an affiliate of the Centre of Excellence in Food Security (CoE).
“Not only do indigenous grains like sorghum have potential to improve diets, if properly marketed, they can contribute to developing small businesses,” Duodu added.
Similarly, Professor Julian May, director of the CoE called for intensifying efforts to bring indigenous grains to the market and make them readily available for consumers. He also emphasised the need for scientists to make their research more accessible to help educate the public about the health-promoting properties of indigenous grains.
This sentiment was echoed 2009 World Food PrizeLaureate, Professor Gebisa Ejeta, who during the NRF Lecture said: “Africa's development must come from within through establishing excellent universities, doing cutting-edge research with scientists that are socially engaged and making policy impact.”
