Prof Melanie Walker is one of two NRF A1-rated scholars at the UFS.

The Higher Education and Human Development (HEHD) research group under the leadership of Prof Melanie Walker has grown to become a pocket of academic excellence and innovation at the UFS. “The group’s research positions universities (if ‘reimagined’) as potentially powerful sites for achieving human development by challenging the status quo and entrenched interests and inequalities,” Prof Walker notes. 

HEHD researchers draw substantially on the capability approach, which offers a contribution to higher education in South Africa, primarily because it derives from a normative framework that places human flourishing as its primary goal, chiming with the country’s transformation goals.

Prof Walker is an internationally acclaimed researcher and academic and one of three A-rated National Research Foundation (NRF) scholars at the UFS. In 2021, she was elected as the first president of the international Human Development and Capability Association (HDCA) from the Global South. Back then, Prof Walker said the UFS already had a strong research presence within the HDCA, and her group was known for its work in African higher education. The HDCA brings together academics who generate ideas and research on human development.

The research group, which was founded by Prof Walker, is an embodiment of the quality and of the impact elements of the institutional narrative of the UFS. The HEHD is now happily based in the Centre for Development Support within the UFS Faculty of Economic and Management Sciences.

Top-tier research outputs from HEHD

The outputs of the HEHD research group have a far-reaching impact, given the nature of its national and international affiliated researchers, students, and collaborators. Members of the group have published 19 peer-reviewed books since 2013, and since 2016, the HEHD has graduated 20 PhDs whose research focuses on diverse aspects of higher education and capabilities across the sub- Saharan region. A range of international examiners in the USA, the UK and Europe attest to the quality of the HEHD’s doctoral graduates.

“I am immensely proud of the quality of the research and collective ethos of our graduate students and our researchers and, as importantly, the substantive focus on human development and social justice in and through higher education in Africa,” Prof Walker says. “As Professor Tristan McCowan and others have noted, this group is quite unique internationally,” she continues.

Projects and research collaborations

The numerous institutional and national and international research collaborations are also testament to the interdisciplinarity of Prof Walker’s academic approach. Various recent and current projects attest to this, for example, the recently completed Miratho project on inclusive higher education learning outcomes for low-income rural youth with Birmingham and Nottingham.

A further current example is the project under the Transforming Education for Sustainable Futures (TESF) with Bristol and Rhodes led by Dr Mikateko Mathebula, and a new edited book underway with Alejandra Boni and Diana Velasco (Spain) on higher education and reparative futures.

 
Furthermore, national collaborations such as the project with colleagues in the Centre for Development Support at the UFS and the University of Pretoria, which will be investigating the sustainable (ecologically and socially), developmental South African university and justice facing university futures from a variety of stakeholder 
perspectives.

This research project is informed by the 17 Sustainable Development Goals, because achieving them cannot be done without the contributions of higher education institutions.

It is thus evident that under the leadership of Prof Walker, the HEHD research group is now established as one of the finest research groups at the UFS and contributes actively to the research and academic excellence at the university.

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.
