Fostering human capabilities in universities may potentially transform education, says Prof Melanie Walker.

Education is at the centre of human life, and has the potential to be a crucial support for democratic life. Prof Melanie Walker’s recent research paper strikes a balance in dealing with people, education and the implications for democracy through the lens of human capabilities theory and practice and her own research.

People and papers

In her capacity as the SARChI Chair in the Higher Education and Human Development Research Programme at the University of the Free State (UFS), Prof Walker recently published a paper titled: Defending the Need for a Foundational Epistemic Capability in Education. It appeared in the special issue of the Journal of Human Development and Capabilities in honour of renowned Nobel Laureate Amartya Sen’s 85th birthday.

Nurturing epistemic justice

Within the context of existing literature such as that of Sen’s concern with the value of education on the one hand, and public reasoning on the other, Prof Walker argues for a foundational epistemic capability to shape the formal education landscape – as well as quality in education – by fostering inclusive public reasoning (including critical thinking) in all students. It would contribute to what Sen calls the ‘protective power of democracy’ and shared democratic rights, which, he argues, are strongly missed when most needed.

“Sen’s approach asks us to build democratic practices in our university and in our society in ways which create capabilities for everyone. If our students learn public reasoning in all sorts of spaces in university, including the pedagogical, they may carry this into and back to society,” she said.

Educating for equality

Empowering society and fighting for justice are some of the crucial contributions made possible through fostering the epistemic capability of all students. “The capability requires that each student is recognised as both a knower and teller, a receiver and a contributor in critical meaning and knowledge, and an epistemic agent in processes of learning and critical thinking,” states Prof Walker.

In a young democracy like South Africa’s, inclusive public reasoning becomes all the more essential in order to achieve equality, uphold rights and sustain democracy as enshrined in the constitution, thereby improving people’s lives.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
