Water is a fundamental human right, says Dr Thulisile Mphambukeli, (left) Senior Lecturer at the Department of Urban and Regional Planning. On the right is Dr Victor Okorie.

Research shows that “access to water and food remains critical to the survival and stability of any nation”. This is according to a team of academics that has been hard at work exploring ways in which to secure water and food in Brazil, Russia, India, China and South Africa (BRICS nations).

These scholars from the University of the Free State (UFS) and North-West University recently published a paper titled: Exploring the Political Economy of Water and Food Security Nexus in BRICS. Dr Thulisile Mphambukeli, Dr Victor Okorie, and Prof Samuel Amusan are members of the Food Security Research Cluster of the South African BRICS Think Tank that has been fervently tackling the water and food in(security) challenge.

Water as a key to social justice 

The team argues that unequal access and distribution of water has in the past led to violent conflict. The paper cites Qwaqwa as one of the many areas affected by water-service protests in the recent past. “Water and food crises are worsening thanks to the intensification of climate change, rapid urbanisation, nutrition transition and population growth. Solutions to these crises partly lie in cooperation and collaboration among nation states, regional economic commissions, and global power brokers.”

What are some of the local solutions? According to the scholars: “For agronomic and husbandry practices, there is a pressing need for research activities on innovative ways of supplying water to crops and animals such that water loss through evaporation and run-off is significantly reduced. 

“Similarly, research activities on redesigning toilets, especially the urinary section – 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 the water and food security nexus crises.”

Improving livelihoods

In an effort to achieve food security, BRICS aims to stimulate domestic capacity for production. Food and nutrition security cannot be achieved without water security, and vice versa. 

It is evident that the water and food insecurity issues are complex. However, concerted efforts are being made by various sectors to solve these challenges and improve the livelihoods of urban and rural citizens within BRICS nations.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
