UFS BRICS-PLUS tackles global challenges
Dr Thulisile Mphambukeli (UFS), Dr Fidelia Dake (University of Ghana), and Dr Victor Okorie (UFS).

Over 70% of the earth is water yet more than two billion people lack access to clean water and sanitation. About 795 million people are food insecure but one third of all food produced in the world, which worth $1.6 billion, is thrown into the dustbin every year. These are the problems, the paradoxes, which seasoned social scientists, engineers and clinicians from universities, research institutions and non-governmental organisations in South Africa, Russia, India, Ghana, Nigeria, and Zimbabwe deliberated at the BRICS-PLUS conference.

The scholars also noted that the grim statistics of water and food-related human suffering, including illnesses, are on not only the increase but overweight and underweight now co-exist in the same household. Dr Victor Okorie, a Postdoctoral Fellow and Dr Thulisile Mphambukeli, a senior lecturer at the Department of Urban and Regional Planning at the University of Free State (UFS), along with Prof Lere Amusan of the North-West University, successfully hosted the first BRICS-PLUS Conference themed: Water, Food and Health Nexus in BRICS-PLUS: Problems, Progress and Prospects were the topics discussed.

The delegates collectively identified some drivers of the problematic paradoxes: including accelerated climate change, urbanisation, inequality, inequity, and population growth. Others were a move from family to factory food and limited physical activity, among other unhealthy lifestyles.

Recommendations based on observation

After the delegates deliberated on various issues of water, food and health nexus in BRICS-PLUS, they made the following policy recommendations:
• There should be strong collaboration among critical stakeholders such as the state, civil society and knowledge institutions with respect to reducing the challenges of water, food and health.

• Issues of gender and the youth should be explicitly incorporated into policies guiding water, food and health nexus across BRICS-PLUS.

• The BRICS-Plus research team should be upgraded into a more permanent organisation in order to strengthen how it deals with the challenges at hand.

• There is a need to balance competing uses of water and other natural resources to prevent further pollution and destruction of the commons.

• Investments in research on water, food and health to generate innovations for sustainable development should inform BRICS’ science, technology and innovation agenda.

• There is a need to promote a zero-waste circular economy through recycling in production, preservation, processing, more equitable distribution and consumption processes to reduce ecological footprints across BRICS-PLUS, and generate energy for sustainable economy.

• It’s necessary to encourage technology transfer, capacity-building and policy learning among member-states

• BRICS should encourage favourable terms of trade among member states with respect to water, food and health issues.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
