Prestige Lecture by Justice Albie Sachs

Invitation

Who actually wrote the Constitution?

The Dean of the Faculty of Law, Prof Serges Kamga, invites you to a Prestige Lecture which will be delivered by Emeritus Constitutional Court Justice Albie Sachs.

Date: 30 October 2024

Time: 17:30

Venue: Equitas Auditorium

RSVP: Before 20 October 2024 (RSVP here)


Albie Sachs is an activist, writer and former judge on the Constitutional Court of South Africa (1994 – 2009). He began practising as an advocate at the Cape Bar at the age of 21, defending people charged under the racial statutes and security laws of apartheid. After two spells of being detained in solitary confinement without trial, first for five months, then for three months, he went into exile in England, where he completed a PhD at Sussex University. In 1988, he lost his right arm and his sight in one eye when a bomb was placed in his car by South African security agents in Maputo, Mozambique. After the bombing, he devoted himself to the preparations for a new democratic constitution for South Africa. When he returned home from exile, he served as a member of the Constitutional Committee and the National Executive of the African National Congress until the first democratic elections in 1994.

Sachs is a Board member of the Constitution Hill Trust, which promotes constitutionalism and the rule of law. He has travelled to many countries sharing South African experiences that might help heal divided societies.

He is the author of several books, including The Jail Diary of Albie Sachs, Justice in South Africa, Sexism and the Law, Soft Vengeance of a Freedom Fighter and The Strange Alchemy of Life and Law. His latest books are We, the People: Insights of an activist judge (2016) and Oliver Tambo's Dream (2017). He received an honorary doctorate in Law from the UFS in 2022.

“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.
