Prof Motlalepula Matsabisa
This week, Prof Motlalepula Matsabisa, will give a keynote speech on Indigenous Knowledge Systems (IKS) and Health during a session at the eighth edition of the UNGA77 Science Summit around the 77th United Nations General Assembly (SSUNGA77).

Prof Motlalepula Matsabisa, Director of Pharmacology at the University of the Free State (UFS), has been invited to give a keynote speech on Indigenous Knowledge Systems (IKS) and Health during a session at the eighth edition of the UNGA77 Science Summit around the 77th United Nations General Assembly (SSUNGA77).

While in New York, Prof Matsabisa will also meet with officials from the Wellcome Trust – a global charitable foundation – where he will present a strong and compelling motivation for the Wellcome Trust to invest in traditional medicines. Says Prof Matsabisa: “I will deliver a compelling message for investment to be made in scientific research and development around traditional medicines. This development will be piloted in a hub-and-spoke model based on the African economic blocks, with the hub being in South Africa. The returns on the investment put in this initiative will be massive for the African continent, both socially and economically, and I believe it will lead to self-sustainability and Africa being a supplier of innovations based on the science of traditional medicines.” 

SSUNGA77 is organised by Intelligence in Science and will take place from 13 to 30 September 2022. It will bring together thought leaders, scientists, technologists, innovators, policy makers, decision makers, regulators, financiers, philanthropists, journalists and editors, and community leaders to increase health science and citizen collaboration across a broad spectrum of themes, including ICT, nutrition, agriculture, health, IKS, and the environment.

Prof Matsabisa, an expert in African traditional medicine (ATM) and Chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19 (REACT), is also the convener of this session, following his successful proposal for such a session. The session will take place in person on 20 September at the UN headquarters in New York. It is an official side event of the UN General Assembly’s 77th anniversary and will be co-sponsored by the permanent missions of Ireland, Spain, South Africa, Brazil, and Bangladesh to the UN.

His message at Science Summit

“At the end of the summit, we are to make recommendations to the UN, EU, and AU on IKS and health developmental matters. This is exciting and nerve-wracking for me, but I will remain calm knowing that I have a message to deliver to the highest global decision-making body. There can be nothing greater than presenting my talk and proposals for consideration to such a body.” 

“I will convey three simple messages, namely the importance of traditional medicines in contributing to universal health coverage, the need for Africa – through the heads of state and governments – to take seriously the local manufacturing of traditional medicines for industrialisation, economic emancipation, and responding to poverty and inequality. The third message is the need for sustained and adequate financial support by African ministries of health for the development, commercialisation, and market access to quality and well-researched, safe, and effective traditional medicines in order to contribute to priority diseases as well as responding to pandemics,” says Prof Matsabisa. 

According to him, this address at SSUNGA77 is a chance to correctly position the story on IKS with arguments based on good scientific evidence. “It means we are getting much closer to the institutionalisation and formal economic contribution of IKS to health, and that the African IKS health system is getting international recognition and acceptance,” he says.
Prof Matsabisa says he hopes the message will emerge clearly from his talk that Africa has the resources for raw materials and that the science, as well as the infrastructure, exists to develop IKS and to contribute to new health products. The spin-off is the industrialisation, job creation, and wealth generation that Africa can offer to the rest of the world.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
