The Dean of the Faculty of Law invites staff and interested individuals to attend the inaugural lecture of Prof Ulrike Kistner, Department of Public Law, titled The ‘person’ in question – legally, grammatically, philosophically.

Date: 17 March 2022
Time: 17:30
Venue: Equitas Auditorium

To attend the lecture, please RSVP to Refilwe Majola at MajolaRRM@ufs.ac.za

More about the speaker:

Prof Kistner has held teaching positions in Comparative Literature at Wits University, Modern European Languages at UNISA, and Philosophy at the University of Pretoria. She is currently working at intersections between political philosophy, social theory, jurisprudence, and psychoanalytic theory.

Abstract:

A major shift has been noted in constitutionalism and human rights frameworks – from human and civil rights to principles centred on ‘personhood’ and ‘dignity’. This shift calls for closer historical-critical investigation of the status of ‘person’. Roberto Esposito directs this inquiry to a philosophical grammar of the impersonal third person.

My contribution to this inquiry sets in with a probing of Esposito’s propositions, considering the post-apartheid elevation of ‘person’ in constitutionalism and philosophical elaborations of communitarianism. To the extent that the concept of ‘ubuntu’ is embedded in a linguistic ontology developed by Kinyarwanda, my argument will navigate between Rwanda and South Africa in the mid-1990s, and between juridical, moral-philosophical, linguistic, and Africanist notions of ‘ubuntu’ and corresponding claims on African philosophy.

The radical questioning of ethnolinguistic tenets on the part of some African philosophers brings me back to the philosophical grammar of the third person which, far from being confined to study old grammar books, opens alternatives to ethnophilosophical approaches to the ‘person’ in question.

“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.
