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.

Honouring Stanley Trapido – one of the most influential historians South Africa has produced

The International Studies Group and the History Department at the UFS hosted a seminar on Stanley Trapido by Prof Charles van Onselen on Monday 11 August 2014.

The seminar honoured the life and work of Trapido, one of the most important and influential historians South Africa has ever produced.

Trapido is probably best known for his work on the causes and consequences of the South African War of 1899–1902. It was to this broad time period that Prof Van Onselen spoke in his paper ‘The Political Economy of the South African Republic, 1881–1895’.

Prof Van Onselen’s lecture provided a major reinterpretation of the origins and causes of the Jameson Raid while emphasising that Paul Kruger’s ZAR was a state beset by crime and corruption. It was particularly fitting that Prof Van Onselen gave the inaugural seminar paper, since Trapido supervised his Oxford doctoral thesis.

The International Studies Group and the History Department were extremely honoured by Trapido’s widow, the Booker Prize nominated author Barbara, attending the seminar. They wish to thank her for donating her husband’s academic library to the UFS.

Following the Sharpeville massacre of 1960, the Trapido-couple emigrated to England. While there, Trapido began to shape what is now known as the ‘revisionist’ school of South African historiography. He argued the importance of analysing capital and class formation, which he maintained informed the racial ideologies that culminated in apartheid.

Prof Van Onselen’s inaugural seminar presentation will be followed later this term by papers from David Moore, Sabelo Ndlovu-Gatsheni and Giacomo Macola.
