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.

Vice-Chancellor honoured with major awards
2013-05-02

02 May 2013

The University of the Free State (UFS) is proud to announce that Prof Jonathan Jansen, Vice-Chancellor and Rector, has been awarded a number of major awards recently.

The University of California in the United States awarded him the Alice and Clifford Spendlove Prize in Social Justice, Diplomacy and Tolerance. The award is made in recognition of persons who exemplify in their work the delivery of social justice, diplomacy and tolerance in the diverse local and global society.

“The committee was very impressed with the commitment that Prof Jansen has had to reconciliation and forgiveness as a way to build bridges and to find common ground. Prof Jansen is following in the steps of many of our greatest peace-time leaders and we support his efforts to bring understanding to all cultures,” said Mark Aldenderfer, chair of the awards committee and Dean of the School of Social Sciences, Humanities and Art at the University of California.

Prof Jansen also received the 2013 Academia Award at the Sixth Annual Ubuntu Lecture and Dialogue Awards Ceremony of the Turquoise Harmony Institute on 4 April 2013 in Johannesburg. The Institute aims to foster relations among different faith and cultural traditions to contribute to the well-being of humanity.

According to the organisers, “outstanding individuals who made noteworthy contributions to dialogue, peace and harmony in the society,” are given recognition during the ceremony. The awards are made in a number of different categories. Prof Jansen was among the recipients who included Graca Machel and the South African National Editors Forum (SANEF). Previous winners of Turquoise Awards include Ahmed Kathrada, Chester Williams, Dr Frene Ginwala and Prof Russel Botman.

On 10 May 2013, Prof Jansen was also honoured by Kappa Delta Pi International Honour Society in Education. He was awarded membership of the Laureate Chapter of the society founded in 1911 which “is comprised of men and women who have made distinguished contributions to education, and is limited to 60 living persons”. Prof Jansen joins an exclusive membership of 293 which includes such luminaries as Albert Einstein, Eleanor Roosevelt, Jean Piaget and George Washington Carver.

Also in the United States, Prof Jansen has been invited to be Messenger Lecturer for Fall 2013 at Cornell University. He will give three lectures and interact with the students and staff of Cornell at various functions.

“This is a significant honour and it will really allow members from across the university to get a deeper appreciation of the work you are doing at UFS and in South Africa more broadly,” said Prof Judith Byfield of Cornell’s Department of History and Director of Graduate Studies at the department’s Africana Studies and Research Centre.

On the local front, City Press published its inaugural 100 World Class South Africans on 28 April 2013. During a rigorous selection process, 100 of our country’s most extraordinary citizens who have achieved world-class status were chosen. Prof Jansen’s achievements procured him a place on this prestigious list in the category: Heroes and Mavericks.
