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.

Lecture: THE BLACKNESS OF BLACK: Africa in the World Today

Audio of the lecture

Profile of Professor Ngugi wa Thiong'o (pdf format)

“Flowers are all different, yet no flower claims to be more of a flower than the other.” With these words Kenyan writer and one of the continent's most celebrated authors, Prof. Ngugi wa Thiong’o, delivered the tenth annual Africa Day Memorial lecture on 25 May 2012 in the University of the Free State's (UFS) Odeion Theatre on the Bloemfontein Campus. The lecture was hosted by the Centre for Africa Studies.

Long before Prof. wa Thiong’o was led inside the venue by a praise singer, chairs were filled and people were shown to an adjoining room to follow the lecture. Others, some on the university's Qwaqwa Campus, followed via live streaming.

In his speech titled the Blackness of Black: Africa in the world today, Prof. wa Thiong’o looked at the standing of Africa in the world today. He highlighted the plight of those of African descent who are judged “based on a negative profile of blackness”.

Prof. wa Thiong’o recalled a humiliating experience at a hotel in San Francisco in the United States, where a staff member questioned him being a guest of the hotel. He shared a similar experience in New Jersey, where he and his wife were thought to be recipients of welfare cheques. He said this was far deeper than overt racism.

“The certainty is based on a negative profile of blackness taken so much for granted as normal that it no longer creates a doubt.”

Prof. wa Thiong’o said the self certainty that black is negative is not confined to white perception of black only.

“The biggest sin, then, is not that certain groups of white people, and even the West as a whole, may have a negative view of blackness embedded in their psyche, the real sin is that the black bourgeoisie in Africa and the world should contribute to that negativity and even embrace it by becoming participants or shareholders in a multibillion industry built on black negativity.”

“Africa has to review the roots of the current imbalance of power: it started in the colonisation of the body. Africa has to reclaim the black body with all its blackness as the starting point in our plunge into and negotiations with the world.”

Prof. wa Thiong’o concluded by saying that Africa must rediscover and reconnect with Kwame Nkrumah’s dreams of a politically and economically united Africa.
