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.

US professor makes the case for public scholarship

The university of the 21st century should not be an ivory tower; rather it should work with communities to co-create things of public value. This was one of the observations made by visiting US Prof. Timothy Eatman. He delivered a public lecture on the topic Public Scholarship and the democratisation of knowledge in the engaged university at the University of the Free State (UFS) on Monday, 15 August 2011. Prof. Eatman challenged people at the lecture to think about richer ways of thinking about engaged public scholarship and said they need to prepare for a new citizenry of academia.

Prof. Eatman, an assistant professor of Higher Education at Syracuse University in the United States, said that knowledge was revealed in diverse ways and advised institutions of higher education to demonstrate an increasing sensitivity to issues of relevance to public good. Prof. Eatman said the present era calls for the development of a more sophisticated understanding of knowledge creation.

Prof. Eatman, who is visiting our country for the first time, brought along his mother, Lorraine, and daughter, Jasmin, who performed a contemporary dance during the event. The family had been in Bloemfontein for the past week or so and Eatman expressed his gratitude to staff and people of Bloemfontein, saying he can deliver personal testimony to the beauty of the Free State.
