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.

Q and A with Prof Hussein Solomon on ‘Terrorism and Counter-Terrorism in Africa’
2015-05-29

 

Political Science lecturer, Prof Hussein Solomon, has launched his latest book, Terrorism and Counter-Terrorism in Africa: fighting insurgency from Al Shabaab, Ansar Dine and Boko Haram, on Wednesday 26 May 2015 at the UFS.

In his book, Solomon talks about the growing terrorist threat in Africa, with the likes of Al Shabaab, Ansar Dine, and Boko Haram exploiting Africa's vulnerabilities to expand their operations. Explaining both the limitations of current counter-terrorist strategies and possible future improvements, this timely study can be appreciated by scholars and practitioners alike.

Q: If you speak of Al Shabaab, Ansar Dine, and Boko Haram expanding operations, do you see possibilities for their expansion even into South Africa, or is expansion mainly focused on northern African countries?
 
A: All three movements are operating out of their respective countries. Al Shabaab has attacked Kenya and Uganda and tried to attack the 2010 Soccer World Cup in South Africa. So yes, there is a danger that they are here and, more importantly, newer groups like ISIS are recruiting in SA already.
 
Q: If the traditional military response is ineffective, what would be a better approach then?

 
A:
What is important is that the force of arms needs to complement the force of ideas. What is being waged is an ideological battle, and, just as the West defeated Communism ideologically in the Cold War, we need to defeat radical Islamism ideologically. In addition, the military response needs to complement the governance and development responses.
 
Q: External players like the US have insufficient knowledge of the context, what would be the knowledge about context necessary for anyone concerned about the terror problem in Africa?
 
A: Allow me to give you some examples. The US trains African militaries to fight terrorist groups, but, when they return to their countries, they stage a coup and topple the civilian government. The US does not seem to understand that arming a predatory military and training them makes them more predatory and brutal, which results in civilians being recruited by terrorists, as happened in Mali. Similarly, the US sent arms to the Somali government, and members of that government sold those arms to Al Shabaab terrorists, the very people they were supposed to fight. So the Americans do not understand the criminalisation of the African state, which undermines good governance and promotes terrorism.
