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.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
