Could wave power be an answer to SAs electricity crisis

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 under the spotlight
2015-08-20

 

"Food insecurity is   becoming an increasing problem at South African universities, much to the surprise of university managers." - Dr Louise van den Bergh, senior lecturer and researcher at our department of Nutrition and Dietetics

More than 70% of early university dropouts in the country were forced to abandon their tertiary studies because of food insecurity and financial need.

This was one of the conclusions drawn during the first higher education colloquium on food insecurity. The colloquium was hosted on by the University of the Free State (UFS) on the Bloemfontein Campus on 14 August 2015, where researchers from universities across the country shared their research about food insecurity on university campuses.

In South Africa, university campuses are not usually associated with food insecurity but, over the last few years, tertiary education has become more accessible to an increasing number of first-generation students and students from low-income households.

Some of the research indicated that students from lower-income households are often lacking financially, even with bursaries. The research has also shown that students frequently have to use part of their bursary money to support their families. This results in students not having enough money to buy food, which means they will do almost anything to get food.

A study by the UFS Department of Nutrition and Dietetics found that as many as 60% of our students are food insecure, and experience hunger frequently. This study was the first of its kind in South Africa. In 2011, the UFS launched the No Student Hungry Bursary Programme to provide food bursaries to food-insecure students.

At the opening of the colloquium, Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said by helping students with a basic commodity like food, you give them much more than food; you give them humanity and dignity.

Dr Louise van den Bergh, senior lecturer and researcher in the UFS Department of Nutrition and Dietetics, explains that the problem is considerably more complex than just providing for students financially.

Dr Van den Bergh says that funders need to reassess bursaries, keeping issues such as food insecurity in mind, and not focusing just on tuition.
