Could wave power be an answer to SAs electricity crisis
Attending a recent guest lecture, were from the left: Prof Marian Tredoux UFS Department of Geology, Prof Stoffel Fourie fromWalter Sisulu University, and Thoriso Lekoetje a third-year UFS Geology student.

South Africa has a 2800-km long coastline with high wave energy potential that can generate electricity. Presenting a lecture at the UFS Department of Geology, Prof Stoffel Fourie discussed wave power as a possible solution to the country’s electricity needs. Prof Fourie is a geophysicist and the chairperson of research and development in the faculty of engineering at Walter Sisulu University.

Power at any time
Wave power is a renewable and sustainable resource. “It can provide continuous base load power because wave energy systems do not suffer from ‘time of day’ issues as other renewable energy options. This means that it can generate power at any time of the day,” said Prof Fourie. 
Discussed also was the wave power advantages and disadvantages. 

Wave energy advantages
• Wave energy is a reliable renewable energy resource;

• Reduces dependency on fossil fuels;

• Wave energy is predictable and consistent;

• Generates little or no pollution to the environment compared to other energy resources; and

• Presents no barriers or difficulty to migrating fish and aquatic animals.

Wave energy disadvantages
• Wave energy conversion devices are location dependent, thus limiting possible sites where they can be implemented;

• Offshore wave energy devices can be a threat to shipping as they are too small to detect by radar; and

• High capital investment required for start-up costs, construction and maintenance.

“Looking at both advantages and disadvantages, there is no doubt that South Africa can use this method to harvest energy. With the right investment and political buy-in, wave power could provide a continuous supply of energy and contribute to all South Africa’s electricity needs,” Prof Fourie said.

Food insecurity at university campuses a growing threat
2015-07-28

Food insecurity on university campuses in South Africa has come to the fore as one of the more pressing subjects that needs to be tackled to ensure the continuing education of disadvantaged students across the country.

On Friday 14 August 2015, the University of the Free State will host the first higher education colloquium on food insecurity on university campuses.  The one-day colloquium will take place during the Arts and Social Justice Week, in collaboration with the UFS’s Institute for Reconciliation and Social Justice Best practices will be shared, exploring the available research on student food insecurity at institutions of higher education.

Food insecurity has emerged as a pressing social justice issue affecting students countrywide. Action needs to be taken to promote the academic success of students, who will ultimately contribute to the country’s economic growth. One of the primary focus areas of the colloquium will be to establish a common practice to address this need.  Universities leaders, staff from wellness and social work departments, and SRC members from across the country who have been invited, and are expected to attend, are the University of Pretoria, the Tshwane University of Technology, North West University, UNISA, and the Central University of Technology.

Professor Jonathan Jansen will participate in a panel discussion alongside Ruda Landman and Prof Edelweiss Wentzel-Viljoen (HPCSA). This promises to be an inspiring meaningful dialogue, by asking the difficult question:  How do we change the food insecurity situation at universities?

The University of the Free State is currently the country’s leading university in addressing food insecurity on all its campuses through its flagship No Student Hungry Bursary programme, which has funded more than 500 students since it was established in 2011.
