With a 7% fiscal deficit on the Gross Domestic Product (GDP) projected by the National Treasury for the 2020/21 financial year, it would not take long to arrive at a dangerous level of debt at the rate that South Africa is borrowing. Although the South African Reserve Bank Governor, Lesetja Kganyago, does not consider a debt to GDP rate of 60% a disaster, he did express his concern regarding the country’s fiscal deficits being over 6% of the GDP.

Governor Kganyago presented a public lecture at the University of the Free State (UFS) on 4 March 2020, focusing on how we should use macro-economic policy and its role in our economic growth problem.

Unsustainable policies 
South Africa’s fiscal situation is not about tight monetary policy. According to the Governor: “Weak growth is endogenous in our fiscal problems. We cannot keep doing what we are doing and hope that growth will recover and save us. Growth is low, in large part, because of unsustainable policy.”

Avoiding an impending crisis
To address the problem, as a policymaker with more than 20 years’ experience, the Governor suggested that the recommendations made by Minister Tito Mboweni be taken into consideration. “The Minister of Finance, Tito Mboweni, is a man who says things that are true even when they are unpopular. His message is that we have to reduce spending and he is right to put this at the centre of our macro-economic debate,” said Governor Kganyago.

The state needs a radical economic turnaround strategy which is able to diminish the risk of losing market access and being forced to ask the International Monetary Fund for help. Governor Kganyago is positive that such a reformative tactic would go beyond monetary policy and ensure that the interest bill ceases to claim more of South Africa’s scarce resources.

“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.
