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.

New building for Centre for Financial Planning Law

During a recent tree planting ceremony, the Centre for Financial Planning Law in the Faculty of Law officially handed over the site for a new building for the centre. The building should be complete by the end of 2012.

The Centre for Financial Planning Law’s present premises has become too small for the needs of the centre, thus a decision was taken to build a new building.

The centre, which was opened in 2001 with three staff members, grew during the past 11 years to a centre with 13 permanent staff members. Some 1 300 students – 120 undergraduate and 1 200 postgraduate students in the Postgraduate Diploma in Financial Planning Law and the Advanced Postgraduate Diploma in Financial Planning Law respectively – are enrolled at the centre. Undergraduate students attend weekly contact sessions while the postgraduate students all study electronically through distance education.

According to Mr Rudolf Bitzer of Bitzer Design Studio, one of the two architecture firms involved in the development of the building, the new building was planned in order to to make provision for future extensions. “The opportunity for the centre to function independently was important from the beginning and facilities had to be positioned in such a way that the lecture hall and committee room could be hired out commercially when lectures were not being presented.

“The building consists of a large reception venue, which gives access to a lecture hall (which can be subdivided), a committee room, public amenities and a reception counter. The centre will present about ten lectures annually in its own building and the lecture hall can accommodate 80 students. Exams will also be written in the venue,” said Mr Bitzer.

The usable inside area of the building totals 827 square metres.

The staff function in their own section of the building, with the offices arranged around a courtyard. Security access makes it a secure environment. In addition, staff have access to a staff room with a service hatch to the reception room, reception counter, personal assistant’s office, nine individual offices and a large open plan office, a storeroom, a cleaners’ room and facilities for staff.

“With the design, an attempt was made to make the building stand comfortably in the landscape without disappearing into the natural landscape. It is an unpretentious building, which seeks to provide well articulated architecture,” said Mr Bitzer.

The architecture firms involved are Bitzer Design Studio and Roodt Architects.
