Ntebohiseng Sekhele hopes her PhD study will address conservation conflicts that exist between communities and protected areas.

The University of the Free State’s Afromontane Research Unit (ARU) based on the Qwaqwa Campus has recently concluded the process of recruiting candidates for the University Capacity Development Programme (UCDP). Through this programme, two historically disadvantaged South African universities; Universities of the Free State (Qwaqwa Campus) and Venda (UNIVEN) and three universities in the United States will be collaborating on a number of PhD research projects.

“The programme is funded through the US-SA Higher Education Network and will give candidates and their supervisors the opportunity to regularly travel to the USA and spend time at participating US universities where their co-promoters will be based and allow them to collaborate with identified suitable academics based at those institutions,” said Prof Geofrey Mukwada, Associate Professor in Geography and the coordinator of the project.

One of the young academics selected for this is Ntebohiseng Sekhele from the Geography Department. She will be doing her research in collaboration with the Colorado State University.

“I am delighted to be part of this programme and it still feels like a dream. I feel honored to be selected to participate in such a prestigious programme. To be chosen amongst other applicants means the coordinators believe in my potential, and I look forward to working towards my full potential,” said Sekhele, who describes herself as ‘a simple and ambitious village girl from Monontsha in Qwaqwa.’ 

Sekhele’s proposed PhD study will focus on determining strategies and impacts of conservation practices by the local communities. “It will address conservation conflicts that exist between communities and protected areas; different interpretations of sustainability (including indigenous knowledge) and offer recommendations of harmonising the conservation practices with the sustainability of conservation areas. There is a great need to develop management strategies that will simultaneously satisfy conservation and human needs. She will be graduating with an MSc (Environmental Geography) degree in 2019.

Other US universities involved in the UCDP are Appalachian State University (ASU) and University of Montana (UoM).

UFS research could light up South African homes
2016-01-21

Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology, is using her research to provide solutions to the energy crises in South Africa.

A young researcher at the university is searching for the solution to South Africa’s energy and electricity problems from a rather unlikely source: cow dung.

“Cow dung could help us power South Africa,” explains Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology.

Reitumetse’s research is trying to understand how the bacteria works that is responsible for producing biogas.

“Biogas can be used for cooking, heating, lighting and powering generators and turbines to make electricity. The remaining liquid effluent can fertilise crops, as it is high in nitrogen, phosphorus and potassium.”

By using cow dung and food waste to produce biogas, we will be able to lower greenhouse gases.

Biogas is produced in a digester - an oxygen-free space in which bacteria break down or digest organic material fed into the system. This process naturally produces biogas, which is mainly a mixture of methane and carbon dioxide.

“Many countries, such as Germany and the United States, have begun generating electricity from cow dung and food waste, through a process known as biogas production. In South Africa, a number of industries, including waste-water treatment facilities and farms, have caught on to this technology, using it to generate heat and to power machines.”

Until recently the world has relied heavily on electricity derived from fossil fuels such as coal, natural gas and oil. Once these fuels have been extracted from underground reservoirs, they are treated or cleaned, transported to power plants and transformed into the electricity that will reach your house. Fossil fuels are considered a ‘dirty’ energy source which gives off greenhouse gases when burned. Those gases are the major contributing factor to climate change.

“We know very little about the interaction of the bacteria inside the biogas digester. To use biogas as a sustainable fuel source, we need to understand and describe the bacteria population and growth dynamics inside the digester to produce biogas optimally. Currently we are testing a variety of feedstock, including bran, maize and molasses, for biogas production potential, as well as optimising the conditions leading to maximum biogas production. We are also exploring the potential to use the effluent as fertiliser on local farms. The ultimate goal is to have biogas systems that will supply our university with clean energy.”
