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.

Weideman focuses on misconceptions with regard to survival of Afrikaans

On the survival of a language a persistent and widespread misconception exists that a “language will survive as long as people speak the language”. This argument ignores the higher functions of a language and leaves no room for the personal and historic meaning of a language, said the writer George Weideman.

He delivered the D.F. Malherbe Memorial Lecture organised by the Department Afrikaans at the University of the Free State (UFS). Dr. Weideman is a retired lecturer and now full-time writer. In his lecture on the writer’s role and responsibility with regard to language, he also focused on the language debate at the University of Stellenbosch (US).

He said the “as-long-as-it-is spoken” misconception ignores the characteristics and growth of literature and other cultural phenomena. Constitutional protection is also not a guarantee. It will not stop a language of being reduced to a colloquial language in which the non-standard form will be elevated to the norm. A language only grows when it standard form is enriched by non-standard forms; not when its standard form withers. The growth or deterioration of a language is seen in the growth or decline in its use in higher functions. The less functions a language has, the smaller its chance to survive.

He said Afrikaans speaking people are credulous and have misplaced trust. It shows in their uncritical attitude with regard to the shifts in university policies, university management and teaching practices. Afrikaners have this credulity perhaps because they were spoilt by white supremacy, or because the political liberation process did not free them from a naïve and slavish trust in government.

If we accept that a university is a kind of barometer for the position of a language, then the institutionalised second placing of Afrikaans at most tertiary institutions is not a good sign for the language, he said.

An additional problem is the multiplying effect with, for instance, education students. If there is no need for Afrikaans in schools, there will also be no  need for Afrikaans at universities, and visa versa.

The tolerance factor of Afrikaans speaking people is for some reasons remarkably high with regard to other languages – and more specifically English. With many Afrikaans speaking people in the post-apartheid era it can be ascribed to their guilt about Afrikaans. With some coloured and mostly black Afrikaans speaking people it can be ascribed to the continued rejection of Afrikaans because of its negative connotation with apartheid – even when Afrikaans is the home language of a large segment of the previously oppressed population.

He said no one disputes the fact that universities play a changing role in a transformed society. The principle of “friendliness” towards other languages does not apply the other way round. It is general knowledge that Afrikaans is, besides isiZulu and isiXhosa, the language most spoken by South Africans.

It is typical of an imperialistic approach that the campaigners for a language will be accused of emotional involvement, of sentimentality, of longing for bygone days, of an unwillingness to focus on the future, he said.

He said whoever ignores the emotional aspect of a language, knows nothing about a language. To ignore the emotional connection with a language, leads to another misconception: That the world will be a better place without conflict if the so-called “small languages” disappear because “nationalism” and “language nationalism” often move closely together. This is one of the main reasons why Afrikaans speaking people are still very passive with regard to the Anglicising process: They are not “immune” to the broad influence that promotes English.

It is left to those who use Afrikaans to fight for the language. This must not take place in isolation. Writers and publishers must find more ways to promote Afrikaans.

Some universities took the road to Anglicision: the US and University of Pretoria need to be referred to, while there is still a future for Afrikaans at the Northwest University and the UFS with its parallel-medium policies. Continued debate is necessary.

It is unpreventable that the protest over what is happening to Afrikaans and the broad Afrikaans speaking community must take on a stronger form, he said.
