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.

The challenges of local governance highlighted at the JN Boshoff Memorial lecture

The annual JN Boshoff memorial lecture was hosted by the Faculty of Economics and Management Sciences in conjunction with the Department of Public Management on 21 August 2014. Mr Kopung Ralikontsane, Director-general of the Free State Provincial Government, presented the keynote address, ‘Challenges Facing Local Government in Service Delivery’.

In his opening remarks, Mr Ralikontsane gave the background of the South African municipal structures, the legal framework within which they operate and the challenges they are currently facing. He added that “local government is a sphere at the coalface of service delivery and if this sphere fails, South Africa would have failed to be a developmental state.”

He said the Free State provincial government has made great strides in developing local communities, with millions of rands invested in various development projects such as water and sanitation, electrification, roads and storm water structures, community facilities and solid waste disposal.

Local government is still faced with other challenges, though. He pointed out that public employees are subject to greater scrutiny and increased demands from citizens. As a result, they have to provide better services, but within stricter limits on resources. Conflict arises due to changing relationships between public servants and citizens, downsizing, restructuring and contracting out of government services and activities.

Despite the various structures implemented by local government, municipalities are serving an ever-growing population in an economic decline. Regulations have been put into place to devise credible Integrated Development Plans (IDPs) to improve municipal infrastructure, build competent management teams and strong operations and increase technical capacity for effective delivery of services.

Mr Ralikontsane invited students to join local government in crafting innovative solutions. “We know the problem, but we need to encourage you to join forces with your local government and tackle them.”

Mr Kopung Ralikontsane has served in local government for two decades and also serves as Head of Administration of the Free State Government and as Cabinet Secretary.
