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.

His research on the implementation of the Integrated School Health Programme (ISHP) in rural South Africa led to André Janse van Rensburg being selected to become part of the Emerging Voices for Global Health (EV4GH) group.

It is a collection of young, promising health policy and systems researchers, decision-makers and other health system professionals. A total of 222 applications from 50 countries were received for this programme, from 3-19 November 2016 in Vancouver, Canada.

The EV4GH is linked to the fourth Global Symposium on Health Systems Research (HSR2016), from 14-18 November 2016. It also taking place in Vancouver and Janse van Rensburg will be taking part, thanks to his research on the ISHP in the Maluti-a-Phofung area. He is a researcher at the Centre for Health Systems Research & Development (CHSR&D) at the University of the Free State (UFS).

The theme of the HSR2016 is Resilient and Responsive Health Systems for a Changing World. It is organised every two years by Health Systems Global to bring together roleplayers involved in health systems and policy research and practice.

Janse van Rensburg also part of Health Systems Global network
The EV4GH goals relate to the strengthening of global health systems and policies, particularly from the Global South (low-to-middle income countries with chronic health system challenges). The initiative involves workshops, presentations, and interactive discussions related to global health problems and solutions.

As an EV4GH alumni, Janse van Rensburg will become part of the Health Systems Global network. Partnering institutions include public health institutes from China, India, South Africa, Belgium, and the UK.

“The EV4GH is for young, promising health
policy and systems researchers, decision-makers
and other health system professionals.”

Research aims to explore implementation of schools health programme
In 2012, the ISHP was introduced in South Africa. This policy forms part of the government's Primary Health Care Re-engineering Programme and is designed to offer a comprehensive and integrated package of health services to all pupils across all educational phases.

Janse van Rensburg, along with Dr Asta Rau, Director of the CHSR&D, aimed to explore and describe implementation of the ISHP. The goals were to assess the capacity and resources available for implementation, identify barriers that hamper implementation, detect enabling factors and successful aspects of implementation and disseminate best practices in, and barriers to, ISPH implementation with recommendations to policymakers, managers and practitioners.

“A lot of people were saying they don’t
have enough resources to adequately
implement the policy as it is supposed to
be implemented.”

Findings of project in Maluti-a-Phofung area
Janse van Rensburg said the ISHP had various strengths. “People were impressed with the integrated nature of the policy and the way people collaborated across disciplines and departments. The school team were found to work very well with the schools and gel well with the educators and principles.”

He said the main weakness of the implementation was resources. “A lot of people were saying they don’t have enough resources to adequately implement the policy as it is supposed to be implemented.

“Another drawback is the referral, because once you identify a problem with a child, the child needs to be referred to a hospital or clinic.” He means once a child gets referred, there is no way of knowing whether the child has been helped and in many cases there is no specialist at the hospital.
