Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

UFS discontinues one Masters programme

2006-07-26

As from next year, the University of the Free State (UFS) will no longer offer one of its specialist master’s degrees in education – the M Ed in Education Management.

The other six M Ed programmes that are currently being offered at the UFS will continue as normal.

The decision to discontinue one of the M Ed programmes follows a national review of M Ed programmes in Educational Management and Leadership by the Higher Education Quality Committee (HEQC) of the Council on Higher Education (CHE).

Of the 23 tertiary institutions whose M Ed programmes in Educational Management and Leadership were reviewed by the HEQC, only 7 received full accreditation.

“The findings of the HEQC affect only one of our M Ed degree programmes, namely the M Ed in Educational Management,” said Prof Magda Fourie, Vice-Rector: Academic Planning at the UFS

“We will be paying full attention to the findings of the HEQC with a view to correcting some of the shortcomings that have been identified by the HEQC and will consider submitting a reviewed proposal for such a qualification in two years time,” she said.

According to Prof Fourie, the programme currently has 30 students enrolled. “These students – spread across their first and second years of the degree programme – will be allowed to complete their studies with the full support of the UFS and the School of Education,” said Prof Fourie.

“The qualification that has been awarded to students who have already completed their studies for this specific M Ed in Education Management degree programme remains a valid qualification and is not affected by the HEQC review,” said Prof Fourie.

She said the UFS welcomed the efforts of the HEQC to ensure that all academic programmes offered by higher education institutions meet certain standards.

“One of the primary problem areas in the M Ed in Educational Management offered by the UFS identified by the HEQC, was that the programme is too practice orientated and must be more theoretical to comply with the academic requirements of a master’s degree. This was a result of the fact that the programme was initially compiled in consultation with principals and the provincial Department of Education to address their needs,” said Prof Fourie.

“The UFS will in the mean time offer an advanced certificate in Educational Management and Leadership from next year. This is a new course that will stretch over a period of two years and will ensure that we can still address the needs of teachers and principals,” said Prof Fourie.

“The UFS remains committed to providing top quality degree programmes in all its six faculties and will continue to work with the HEQC in ensuring that this actually happens,” said Prof Fourie.
