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.

Prisca Odero awarded ASA Presidential Fellowship

Dr Prisca Odero, a Centre for Africa Studies (CAS) fellow, received the African Studies Association (ASA) Presidential Fellow award in Indianapolis, USA, recently.

She was nominated for ASA by Dr Cyril Obi from the Social Science Research Council (New York), and was selected competitively, based on her PhD thesis and applied research work in rural development in Africa. Odero obtained her PhD in Africa Studies from the UFS at the July 2014 Graduation Ceremony.

On 22 November 2014, Dr Odero gave a public lecture at the Brooklyn College of the City University of New York. The event was hosted by the Political Science Department at the College.

Her paper, titled Sources and role of social capital in smallholder agricultural production: The value of membership of community groups to Zimbabwe rural livelihoods, sought to address the question of whether social capital contributed to the resilience of rural households in the face of economic difficulties and food security challenges. Dr Odero argued that the link between social capital and agricultural production is manifest in the ways in which farmers use social capital derived from membership of groups to alleviate agricultural production challenges.

Smallholder farmers in Zimbabwe, who face constraints in acquiring the necessary resources for production because of failing markets and reduced agri-industry productive capacity, employ a range of methods to deal with these challenges.  She presented an analysis of data collected through focus group discussions with representative groups and through a household survey.

Dr Odero’s research forms part of a book project. While books on agricultural development knowledge do exist, more studies analysing issues and offering solutions from an African perspective would help to address the gap in African knowledge production.
