Researchers to represent UFS at BRICS Summit

A Brazil, Russia, India, China and South Africa (BRICS) delegation is to hold the 10th Annual BRICS Summit in the last week of May 2018 in Johannesburg. Dr Thulisile Mphambukeli, leader of the University of the Free State (UFS) research team alongside Dr Victor Okorie from the Department of Urban and Regional Planning, in collaboration with Prof Lere Amusan of North-West University, will ensure that water and food security is a prominent feature on the gathering’s agenda.
 
First, the project titled: “Exploring the political economy of water and food security nexus in BRICS and Africa” will debut at the National Institute for the Humanities and Social Sciences BRICS Think Tank Forum”.

According to Dr Mphambukeli, the key to water security is attitudinal change by means of education and conscientisation. This, she is adamant about, holds the potential to drive behavioural adjustments in the way society interacts with water.
 
Genetic and social approaches
Dr Okorie asserts that if strides towards reducing the demand for water were to be made, research efforts should be geared towards effecting changes at DNA level. Meaning we need to explore waterwise ways that enable crops and animals to thrive optimally. 

The project also looks at social dimensions of water such as flushing a toilet. “Research activities on redesigning toilets, especially the urinal, where more than nine litres of water are used to flush less than one cubic centimetre of urine, are timely in the context of managing water and the food nexus crises,” said Dr Okorie.

Combining the genetic and social approaches would allow us to produce more with a smaller water footprint. This can be made possible by implementing precision agriculture which is about estimating and applying exact quantities of water and nutrients needed for the production of crops or the raising of livestock.

Paradigm shifting policies
Prof Amusan said the team intended to propose functional solutions that take the quality of water into consideration. Equitable production and distribution of water depends on endorsing policies of co-production between citizens, governments and the public sector. BRICS member states mutually consider water and food security as an issue of paramount significance, hence its feature on this prestigious summit’s agenda.

Scientists discover a water reservoir beneath the Free State
2009-12-09

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
