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.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
