Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation

The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

Colloquium probes solutions for student hunger
2015-08-03

While higher education is deemed necessary for future financial security, high tuition and accommodation fees, as well as increasing food prices, are forcing students to drop out of university.

Dr Louise van den Berg, Senior Lecturer and Researcher at the University of the Free State (UFS), says university campuses are not often associated with food insecurity, but, due to the increase in first-generation students and students of low-income households receiving tertiary education, student hunger at some of the country’s prominent campuses needs urgent intervention.

On 14 August 2015, the University of the Free State (UFS) will host the first higher education colloquium in the country, on food insecurity on university campuses.  Best practices will be shared, exploring the available research on student food insecurity at institutions of higher education. Programme of the colloquium.

A study by the UFS Department of Nutrition and Dietetics found that as many as 60% of students on our campuses were food-insecure, and experienced hunger. This study was the first of its kind in South Africa, and led to the No Student Hungry Bursary Programme (NSH) at the UFS. The level of severe food insecurity reported was much higher than that reported in Australia, New York, and Hawaii by the only other three studies that have been done.

“The UFS is not the only campus struggling with food insecurity,” say Dr Van den Bergh.

“The general misconception is that a student, having money for studies, should have money for food. Funders need to reassess bursaries, keeping issues such as food insecurity in mind, and not just focusing on tuition.”

Bursaries, especially government funding, became easily available to bridge the inequality gap in our country.

“Although bursaries pay for tuition, many students have no resources for food. Universities currently have a 50% drop-out rate currently, with many students dropping out due to poverty.”
