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.

UFS to send a second group of first-year students overseas
2011-03-23

Some of the students who were chosen in 2010

Following the resounding success of the University of the Free State’s (UFS) Student Leadership Development Programme in 2010, the UFS will send a second group of students to the USA in 2011 and also extend the programme by sending students to various universities in Europe and Asia.

This year a total of 150 first-year students will be selected compared to the 71 students that were selected last year. Last year’s group of students spent two weeks, between September and October 2010, at various universities across the United States.
                                         
The programme intends to expose the students to diverse cultures and enable them to learn leadership skills. The goal of the programme is to build a new class of UFS students who become leaders during their years of study and commit to building a non-racial community during and beyond their years at university.
 
Mr Rudi Buys, the UFS Dean of Student Affairs, says: “With the programme we want to develop participants’ thinking and capacity to lead in the contexts of diversity and change and we hope to direct them to programmes leading to change in student life in general upon their return.”
 
The three core purposes of allowing students an opportunity to study abroad are:
  • to introduce South African students to positive models of racial integration and integrated residential life;
  • to share and exchange ideas around issues of race, racism, racial integration and racial reconciliation, with undergraduate students abroad; and
  • to build long-term networking and collaboration between academics and researchers interested in scholarly work on themes of race, reconciliation and social justice.
 
Last year students were selected based on their ability to reflect critically on knowledge of societal issues and successful candidates were put through a preparatory development programme. They were divided into groups and given assignments to complete during the programme. A similar selection process will be undertaken this year.
 
Upon their return, last year’s group of students demonstrated extremely positive outcomes, during an assessment of the project’s goals and achievements. More than 80% of participants agreed that the course met all expectations; the content was meaningful and challenged their existing views. More than 90% felt that the course meaningfully addressed diversity. Among the successes achieved by the programme is the influence of participants in the student community.
 
Many serve as peer mentors for the Gateway First-Year Welcoming and Orientation Programme, while others serve as mentors in well-being and academic peer advisory programmes. Many have also been elected as members of executive committees of student associations and management committees in residences, while some have availed themselves to run for student governance structures throughout 2011 and 2012.
 
The programme proved to be so successful that it was decided to expand the number of students selected for the programme to 150 this year and first-year students are invited to apply. It is envisaged that 90 students will visit American universities, while 60 will visit institutions in Europe and Asia.
 
Last year the students were hosted by, amongst others, Cornell University, the University of New York, Cleveland State University and the University of Massachusetts.
Yale University, Amherst College and other American universities will join these host universities in 2011, in addition to the European and Asian institutions.
