Dr Katlego Mashiane
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.

Alcinda Honwana: Youth Protests Main Mechanism against Regime
2015-05-25

Prof Alcinda Honwana

"Enough is Enough!": Youth Protests and Political Change in Africa (speech) 

The Centre for Africa Studies at the UFS hosted an interdisciplinary project on the Bloemfontein Campus from 20-22 May 2015.

The project, entitled Contemporary Modes of Othering: Its Perpetuation and Resistance, looked at different perspectives, representations, and art forms of otherness, how it is perceived, and how it is resisted.

The annual Africa Day Memorial Lecture was held on Thursday evening 21 May 2015 at the CR Swart Auditorium. Guest speaker Prof Alcinda Honwana addressed the subject of ‘Youth Protests and Political Change in Africa’.

“Youth now seem able to display what they don’t want, rather than what they do want,” Honwana said in her opening remarks. “Thus, we see the young driven to the streets to protest against regimes.”
 
Honwana shed some light on recent examples of youth protests in Africa that have enjoyed global attention. Looking at the protests in Tunisia (2010), Egypt (2011), Senegal (2012), and Burkina Faso (2014), it is clear that these events in northern and western Africa have inspired others globally. Yet, Honwana stated that, despite these protests, no social economic change has been seen, and has left dissatisfaction with new governments as well.

“Once regimes fall… young activists find themselves more divided, it seems…

“Which leaves the question: Will street protests remain young people’s main mechanism to avert those in power?”

Background on Prof Alcinda Honwana:

Alcinda Honwana is currently Visiting Professor of Anthropology and International Development at the Open University (UK). She was chair in International Development at the Open University, and taught Anthropology at the University Eduardo Mondlane in Maputo, the University of Cape Town in South Africa, and the New School for Social Research in New York. She was programme director at the Social Science Research Council in New York, and worked for the United Nations Office for Children and Armed Conflict. Honwana has written extensively on the links between political conflict and culture, and on the impact of violent conflict on children and youth, conducting research in Mozambique, the Democratic Republic of the Congo, Angola, Colombia, and Sri Lanka. Her latest work has been on youth and social change in Africa, focusing on Mozambique, Senegal, South Africa, and Tunisia.

Honwana’s latest books include:

• Youth and Revolution in Tunisia (2013); 
• Time of Youth: Work, Social Change, and Politics in Africa (2012);
• Child Soldiers in Africa (2006);
• Makers and Breakers: Children and Youth in Postcolonial Africa (2005, co-edited).

Honwana was awarded the prestigious Prince Claus Chair for Development and Equity in the Netherlands in 2007.
