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.

Institute for Reconciliation and Social Justice: cultivating humanity
2014-12-15

Directors of university centres focusing on Social Justice, Diversity and Transformation met at the UFS to establish the Directors' Forum. The forum discussed the state of higher education transformation in South Africa  The forum consists of (from the left) Mr Allan Zinn from the The Centre for the Advancement of Non-racialism and Democracy at the Nelson Mandela Metropolitan University, Profs Melissa Steyn from Wits University's Centre for Diversity Studies,  Andre Keet Director of the The Institute for Reconciliation and Social Justice at the University of the Free State; Rozena Maart  from The Centre for Critical Research on Race and Identity  at the University of KwaZulu Natal and Mr JC van der Merwe, researcher at the UFS Institute for Reconciliation and Social Justice

The Institute for Reconciliation and Social Justice at the University of the Free State (UFS) provides a critical space that brings different voices, ideas and practices together to advance the Human and Academic Projects of the university. Students, staff and community members meet here to find ways to engage with diverse views, realities and aspirations.

“We cultivate humanity so that reconciliation and social justice can be expressed in our everyday life and we work against disrespect and inequalities on our campuses and in our society,” says Prof André Keet, Director of the Institute for Reconciliation and Social Justice.

“Through our various critical conversations, public lectures, seminars and colloquia, fresh understandings and ideas come to the fore and new inclusive ways of doing life in a local and global multicultural society are invented,” Prof Keet says. A host of international experts formed part of the institute’s events during 2014.

Dr Charles Alexander (University of California), Prof Halleh Ghorashi (Vrije Universiteit Amsterdam), Prof Alex Hinton (Rutgers University), Dr Shirley Anne Tate (University of Leeds) and Prof Susan Spearey (Brock University) were but a few of the international experts contributing to the work of the institute during the last year.

“We play key roles in transformation debates within Higher Education South Africa (HESA) and ministerial processes,” Prof Keet says. “We promote, protect and monitor human rights across our campuses and are frequently requested to support the work of the South African Human Rights Commission and to provide advice to other state agencies.”

The institute prides itself on their leading-edge research on social cohesion, reconciliation, human rights and higher education transformation. In addition, staff of the institute teaches, on invitation, at various faculties, as well as at other national and international universities.

To further bolster their impact, the institute is launching three master’s and doctoral postgraduate programmes in January 2015.
