WomenOfKovsies Dr Hoppener research affects access of rural youth to university
Dr Mikateko Höppener is also the author of a book titled, Engineering Education for Sustainable Development: A Capabilities Approach, which is based on her PhD research.

Since September 2016, Dr Mikateko Höppener and a team of researchers have been engaged in a four-year long investigation of the multidimensional factors and dynamics that influence low-income learners’ opportunities to access, participate, and succeed in higher education.

Dr Höppener is a Senior Researcher at the university, working under the leadership of Prof Melanie Walker, South African Research Chairs Initiative (SARChI) Chair and Director of the Higher Education and Human Development Research Programme.

Women in academia

Dr Höppener is part of a team comprised of women whom she constantly learns from and who inspire appreciation.. “I am filled with gratitude for being in the position I am in as a young woman. I have the privilege of working with a team of very inspirational, motivating and encouraging women. The Miratho Project is led by a woman and the rest of the team members are also women,” she says.

Access to higher education
The Miratho Project is undertaken in collaboration with Thusanani Foundation, a youth-led, nonprofit organisation. It is funded by the Economic and Social Research Council, and the UK’s Department for International Development. Rural and township learners from low-income backgrounds are the subject of this multimethod, longitudinal study which tracks their progress into higher education and through to employment.

Among its key objectives, Miratho aims to develop a multidimensional learning outcomes index as an instrument of public debate and guiding government policy. As such it contributes to transforming and decolonising higher education.

“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.
