Research informs about sustainable use of fresh water for food production

The fact that South Africa is a water-scarce country has been highlighted during the past couple of years, and even city dwellers were suddenly very aware of the drought due to the strict water restrictions. These are the words of Dr Frikkie Maré, Head of the Department of Agricultural Economics at the University of the Free State (UFS) and one of the graduates who received his PhD on water-footprint assessment studies at the recent June 2018 graduations.

The department is currently involved in various water-footprint and water-management research projects which assist in providing solutions for better water management in the future. “As department, we want to be at the forefront of research that will assist all agricultural producers with sustainable production practices to ensure economic, environmental, and social sustainable food and fibre products for the society at large,” said Dr Maré.

Research funded by Water Research Commission
The UFS recently conferred two PhD degrees (Drs Enoch Owusu-Sekyere and Frikkie Maré) and one master’s degree (Adetoso Adetoro) in the Department of Agricultural Economics. All three have been working in the field of water-footprint assessment. The research formed part of two different projects that were initiated and funded by the Water Research Commission.

According to Dr Henry Jordaan, Senior Lecturer in this department, four of his students already received their master’s degrees on the topic of water-footprint assessment, while two students are busy with PhDs and three more are working on their master’s degrees.

Topic gains momentum in research community
The water-footprint concept serves as a useful indicator to sensitise society about the impact of the food we eat on scarce freshwater resources – from agricultural producers using water to produce primary food crops and products on the farm, to the end consumer buying the food products in the retail store in town.

“Water-footprint assessment is a relatively new field aimed at informing the sustainable use of fresh water for food production. This topic is gaining momentum in the research community, given the substantial increase in the global population in the context of freshwater resources that is getting increasingly scarce. The challenge is to feed the growing population while still using the scarce freshwater resources sustainably.

Volume of water used to produce food
“In order to inform water users on how to use the resource sustainably, it is important to know the volume of water that was used to produce the required food products. Through our research, we are contributing to this knowledge by assessing the volume of water that was used to produce selected products, and to interpret the water use in the context of water availability to gain insight into the degree of sustainability with which the resource is used. The results are expected to inform water users, water managers, and policy makers regarding the sustainable use of fresh water for food production,” said Dr Jordaan.

Researcher shares platform with Nobel Laureate at conference on nanomedicine

Profs. Lodewyk Kock and Robert Bragg from the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) both presented lectures at the first International Conference on Infectious Diseases and Nanomedicine that was held in Kathmandu, Nepal, late last year.

At the conference, also attended by senior representatives from the International Union of Microbiological Societies (IUMS), Prof. Kock delivered one of the two opening lectures, titled: Introducing New Nanotechnologies to Infectious Diseases (the other opening lecture was presented by Nobel Laureate, Prof. Barry J. Marshal). Prof. Kock also participated in the farewell address.

In two excellent lectures, Prof. Bragg spoke on Bacteriophages as potential treatment option of antibiotic-resistant bacteria, and on Bacterial resistance to quaternary ammonium compounds.

For Prof. Kock this very first conference on infectious diseases and nanomedicine was followed by a very exciting yeast research excursion through the Mount Everest Highway which winds through the villages of the Sherpa tribe.

He describes his journey: “The Mount Everest Highway is a rough road stretching through hills and glacial moraines of unfamiliar altitudes and cold temperatures. Throughout the journey I had to take care of not contracting altitude sickness which causes severe headaches and dizziness.

“The only way of transport is on foot, on long-haired cattle called Yaks, donkeys and by helicopter. After flying by plane from Kathmandu (the capital of Nepal), I landed at Lukla, regarded as the most dangerous airport in the world due to its short elevated runway and mountainous surroundings. From Lukla, the land of the Sherpa, I walked (trekked) with my Sherpa guide and porter (carrier) along the Everest Highway surrounded by various Buddhist Mani scripture stands, other Buddhist representations and many spectacular snow-tipped mountains of more than 6 000 m above sea level. Of these, the majestic mountain called Ama Dablam (6 812 m), the grand 8 516 m high peak of Lhotse and to its left the renowned Mount Everest at 8 848 m in height, caught my attention.

“Dwarfed by these mountain peaks on the horizon, I passed various villages until I eventually reached the beautiful village called Namche Bazar, the heart of the Khumbu region and hometown of the Sherpa. This took three days of up to six hours walking per day, while I spent the nights at the villages of Phakding and Monjo. From there I walked along the Dudh Kosi River which stretches towards Mount Everest, until I reached the high altitude Everest viewpoint – the end of my journey, after which I trekked back to Lukla to return to Kathmandu and South Africa.

“This expedition is the first exploration to determine the presence of yeasts in the Everest region. Results from this excursion will be used in collaborative projects with local universities in Nepal that are interested in yeast research.”
