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.

UFS takes lead in improving quality of training in economics in schools
2006-06-20

The fourth international workshop for trainers in the National Council on Economic Education’s (NCEE) outreach programme for Africa, Latin America, Asia and the Middle East will be presented in Bloemfontein from 18-24 June 2006.

 “Because of the rapid success we achieved in the Free State with similar workshops in Economics education that were presented by the NCEE the past year, we have now invited representatives from education departments and universities of five other provinces to attend the international workshop for trainers,” said Prof Klopper Oosthuizen, lecturer at the University of the Free State’s (UFS) Department of Agricultural Economics and initiator of the cooperative agreement with the NCEE.

 The UFS and the Free State Department of Education are the NCEE’s first partners in Africa who received this training.  “The attendance of the five provinces and universities is the first step in the extension of the programme to the rest of the country,” said Prof Oosthuizen. 

 The NCEE is based in the United States of America (USA) and the workshop forms part of the council’s effort to improve the quality of the training of Economics teachers and lecturers across the world. 

 “South Africa is urgently in need of efforts to improve the integration of black people into the market economy.  An understanding of how markets work is one of the pillars of democracy.  Equipping young people with economic understanding and skills will help empower them for responsible roles as individuals and citizens,” said Prof Oosthuizen.

 According to Prof Oosthuizen representatives from the education departments of the Northern Cape, Western Cape, Eastern Cape, KwaZulu-Natal and North West will also be attending the international workshop for trainers.  Representatives from the Universities of Rhodes, of KwaZulu-Natal, North West and the Durban University of Technology as well as the Cape Peninsula University of Technology will also attend the workshop.

 During this workshop teachers and lecturers in Economics will receive certificates. 

 Various subjects will be covered during the workshop such as world trade patterns, cost and benefits of free trade, exchange rates and international finance.  The training will be done by representatives from the NCEE by using methods such as direct instruction and role play.

 The NCEE is also in the process of training teachers and learning facilitators in the Free State in an effort to improve the quality of Economics classes in secondary schools. 

 “A group of 84 teachers and learning facilitators were trained in December 2005, 50 were trained in January 2006 and the last group of 40 will be trained at the UFS Main Campus in Bloemfontein from 26 June - 1 July 2006,” said Prof Oosthuizen.

 During this seminar the teachers will be trained in issues such as broad social goals in an economy, economic decision making, government’s role in a market economy and fiscal policy.  The training will also be done by representatives from the NCEE.

 The NCEE has been working together with international partners since 1992 to strengthen their Economics teaching systems.  They have already succeeded in increasing literacy in Economics at schools in the USA and more than 20 East Block countries.  More than 1,5 million learners in the East Block countries have already been served by this initiative.  Since 2004 the NCEE’s focus has moved away from the East Block countries to Africa, Asia, Latin America and the Middle East.

 “Our future plans include strengthening the growing partnership between the UFS, the Free State Department of Education and the NCEE.  We also want to establish a council and centres for economic education which will serve as an umbrella for our joint efforts,” said Prof Oosthuizen.
