Interdisciplinarity in Action


Lunchtime learning webinar on


The  Intersection between Science and Visual Arts


In this webinar, Prof Willem Boshoff and Prof Louis Scott, both from the University of the Free State, will discuss the intersection between science and the visual arts. The webinar will explore how new levels of understanding may emerge when seemingly unrelated fields of interest intersect, supported by the ideas we may find in the endless diversity of nature.

This webinar is part of a series of three webinars on Interdisciplinarity presented from November to December 2020 via Microsoft Teams for a duration of 45 minutes each. The webinar topics in the series explore the intersection between Neuroscience and Music, between Science and Entrepreneurship, and between Science and Visual Arts. 
 
Date: Tuesday 8 December 2020
Topic: The intersection between science and visual arts 
Time: 13:00-13:45 (SAST)
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 7 December 2020 
Platform: Microsoft Teams

Introduction and welcome
 
Prof Corli Witthuhn – Vice-Rector: Research at the University of the Free State 

Presenters

Prof Willem Boshoff
Willem Boshoff is a Senior Professor in Fine Arts at the University of the Free State. As a conceptual artist, he engages primarily with language. Notably, his works have included the writing of several themed dictionaries, most often made accessible to a broad audience in the form of large art installations. His broad interdisciplinary interests, including the fields of botany, music, and lexicography, have over the years led to the development of a digital research archive, which he recently donated to the University of the Free State.  Prof Boshoff’s work is exhibited extensively, both locally and abroad, and has been included in major private collections and museums. Recently, he became the first South African artist to be awarded an A2 rating by the National Research Foundation (NRF). 

Prof Louis Scott
Prof Louis Scott is a retired professor and mentor in the Department of Plant Sciences at the UFS, with an interest in visual arts. He studies fossil pollen in natural lake, cave, swamp, and fossil dung deposits. He attempts to reconstruct our heritage associated with African prehistory through environmental history, including natural long-term processes of change. Prof Scott is widely published in this field, serves on the editorial boards of international journals, and has a B-rating with the National Research Foundation.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
