Striving to make a difference in the field of biodiversity conservation, Dr Katlego Mashiane decided to pursue a PhD in Geography, focusing on the spatial modelling of grassland diversity and nutrients in subalpine environments. He received his PhD during the recent April graduation ceremonies on the Qwaqwa Campus.

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age. 

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park. 

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

Professor Antjie Krog to deliver public lecture at UFS Bloemfontein Campus
2015-06-19

Professor Antjie Krog – illustrious author, poet, and academic – will deliver a public lecture at the University of the Free State’s (UFS) Bloemfontein Campus. The topic of her discussion will be ‘They Couldn’t Achieve their Goal with Me: Narrating Rape during the South African War’.

Prof Krog’s lecture will be the third instalment of the Vice-Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past. The lecture series is hosted by Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness, and Reconciliation Studies at the UFS, as part of a five-year research project funded by the Andrew W. Mellon Foundation.

Details of the event:

Date: Tuesday 23 June 2015
Time: 12:00
Venue: Albert Wessels Auditorium, UFS Bloemfontein Campus
Members of the public are welcome to attend
RSVP to Jo-Anne Naidoo: NaidooJA@ufs.ac.za

Acts of rape during South African War

To set the context of her lecture, Prof Krog explains that, about two months before the South African War officially ended on 31 May 1902, affidavits were taken from women about transgressions experienced at the hands of British soldiers. These acts included plunder, killing of stock, abduction, sexual assault, and rape. Her lecture is the first scholarly focus in terms of narrative and agency on the affidavits of 24 incidents of sexual assaults and rape since the 25-year embargo on these documents was lifted in 1982. The shelving of these affidavits is indicative of how even transcultural multiple processes failed to create an honest discourse in post-colonial South Africa about sexual violence.

Paving the way to healing historical wounds

The series focuses on the portrayal of trauma and memory in multiple ways – such as the narrative arts represented by Prof Krog. These forms of expression may ultimately pave the way to healing historical wounds.

“This topic is very timely, given a recent NRF grant we’ve been awarded for research on transgenerational trauma related to the South African war,” Prof Gobodo-Madikizela says in anticipation of the lecture.

Previous instalments of Vice-Chancellor’s Lecture Series

The first instalment of the Vice-Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past was delivered by former Constitutional Court Judge, Albie Sachs, in which he discussed ‘Sites of memory, sites of conscience’. Internationally acclaimed composer and sound artist, Philip Miller, delivered the second lecture, ‘Disrupting the Silence: The Past and Transnational Memory’.
