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.

Almost 2000 degrees and diplomas conferred at Winter Graduation
2015-06-26

Live streaming will be available on: http://livestream.ufs.ac.za/

The 2015 Winter Graduations are almost underway. The highlight on the university calendar for every graduate will take place on the Bloemfontein Campus on 1-2 July 2015. On 1 July 2015, diplomas will be awarded by the Centre of Financial Planning Law (331 in total) and the School of Open Learning (376 in total). On 2 July 2015, a total of 1 220 master’s and doctoral degrees will be awarded to graduates from all seven faculties.

A highlight at this year’s Winter Graduation is the awarding of three honorary degrees by the university. Ambassador Lakhdar Brahimi, Dr Mercy Oduyoye and Mr John Samuel will receive honorary degrees.

On 17 August 2012, Ambassador Brahimi was appointed by the United Nations as the new peace envoy to Syria, replacing Kofi Annan. He is also a member of the Commission on Legal Empowerment of the Poor, the first global initiative to focus specifically on the link between exclusion, poverty and the law. Prof Heidi Hudson, Head of the Centre for Africa Studies at the UFS, will receive the honorary degree on his behalf.

Dr Oduyoye is widely regarded as one of the most influential women theologians Africa has produced in recent history. Currently, she directs the Institute of African Women in Religion and Culture at the Trinity Theology Seminary in Legon, Ghana.

Mr John Samuel, who will receive an honorary award, is also scheduled to be a guest speaker at the two ceremonies on 1 July 2015.

Wednesday 1 July 2015:

John Samuel will be the speaker at both ceremonies. He is one of South Africa’s leading education experts with international and national experience, covering a period of more than forty years. He was involved in the founding of the South African Campaign: Public Participation in Education Network (PPEN), established the Centre for Education Policy Development, the Joint Working Group (for The National Party Government and the ANC), the National Education Conference, and the National Education and Training Forum. He also made leadership contributions to the First Education and Training White Paper, the Transformation Strategy for the National Education Department, and the first Green Paper on Higher Education.

John is also Senior Programme Director of the WK Kellogg Foundation in the USA. He has also been the Chief Executive of the Nelson Mandela Foundation, and the CEO of the Oprah Winfrey Leadership Academy for Girls.

Thursday 2 July 2015:

Nataniël will be the speaker at both ceremonies. Nataniël is a singer, songwriter, and South African entertainer, who has crossed from the alternative circuit to the stage. For the past 10 years, he has become well-known for his outspoken Kaalkop column in SARIE magazine. His solo career was launched in 1987 and, since then, he has released 16 albums, staged more than 70 original theatre productions, and published 15 books. Over the past two decades, Nataniël has gained the title of South Africa’s leading exponent of the solo stage act. He manages Kaalkop Studio, his lifestyle retail company, and records on his own independent label, Nataniël House Of Music. He is an ambassador for Child Welfare SA, and also heads his own charitable foundation, The Nataniël Progress Project.
