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.

Zubeida Jaffer short film to feature on SABC3

The nation-building initiative known as 21 ICONS South Africa, was recently thrilled to announce that Zubeida Jaffer will feature in their second season due to her professional excellence as a journalist and author.

Jaffer is a well-known South African reporter and author and has been a writer-in-residence at the UFS for three years now. The 21 ICONS project was inspired by Nelson Mandela and has created a movement for positive change. By sharing the stories of iconic South African men and women, the intention is to inspire new generations to follow in their footsteps.

One icon is featured per week in a visual celebration of engaging and entertaining portraits and short films, along with an essay biography across multiple media platforms such as print, broadcast, outdoor and social media. Jaffer’s short film will be broadcasted on 2 November 2014 at 20:27 on SABC3 and her collectable portrait will be published in City Press on the same day.

Jaffer’s short film discusses her truth as a journalist and activist who was a key figure in the struggle movement in the Western Cape during apartheid. In an intimate conversation with Adrian Steirn (creator, photographer and director of 21 ICONS, Jaffer talks about her journey as a journalist who always seeks to uncover the truth and give people who don’t have a voice an outlet to express their views, opinions and thoughts.

Other iconic South Africans that have featured on 21 ICONS, were among others, Francois Pienaar (former Springbok rugby captain who won the 1995 Rugby World Cup), Pieter-Dirk Uys (satirist who used comedy and caricature to oppose the apartheid government) and Frene Ginwala (the first female speaker in the National Assembly of South Africa).

With the country celebrating 20 years of democracy, the message that everyone can do something to make a difference – which is portrayed in these powerful and inspiring stories that make up the second season of 21 ICONS – has been well-received by South Africans.

Be sure to get your City Press early and tune in on the evening of 2 November 2014 to see Jaffer’s feature on 21 ICONS.

Jaffer is also the publisher of the Journalist website (http://www.thejournalist.org.za/) launched earlier in 2014, of which the UFS is the founding member. The Journalist is “an independent, non-profit organisation working with the academic community and a range of credible online entities to make their knowledge more accessible to the wider public.”
