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.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
