Conference
At the meet-and-greet last night, were from left Prof Ruad Ganzevoort, Diversity Officer and Dean of Theology and Religion at VUA, Prof Francis Petersen and Dr Gene Block, Chancellor of UCLA.

The Unit for Institutional Change and Social Justice at the University of the Free State (UFS) is hosting a colloquium on Fragility and Resilience: Facets, Features and Transformation in Higher Education which started on 29 January, with the official progamme concluding on 30 January 2020.

The colloquium is a annual collaborative partnership between the UFS, University of California, Los Angeles (UCLA), and the Vrije Universiteit Amsterdam (VUA).

Apart from the overarching themes the colloquium also placed some focus on mental health, within this context as all three regions are witnessing a spike in mental health issues among students and staff as well as a deficit in terms of being able to sufficiently address the crisis.

“All three universities are committed to discussing global developments in diversity and transformation in higher education to discussing global developments in diversity and transformation as it may constitute itself in higher education circles around the globe,” says Dr Dionne van Reenen, convener of the 2020 colloquium and research fellow at the unit.  

The idea is to discuss what has and has not worked and, hopefully, access best practices in a variety of contexts. The partnership between the three universities spans over six years starting in 2014 when the UFS first hosted the research colloquium. It is the third time the UFS has hosted the colloquium.
 
Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, along with other members of the UFS Rectorate, attended a meet-and-greet on Monday 28 January 2020, and was joined by Dr Gene Block, Chancellor of UCLA, Vice Provosts Cindy Fan, Patricia Turner, Charles Alexander, Professors Abel Valenzuela, John Hamilton and Dr Shalom Staub, director of Community Learning, as well as Prof Ruard Ganzevoort, Chief Diversity Officer and Dean of Theology and Religion at VUA

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.”
