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.

Headed by Prof Ian Phimister, the UFS International Studies Group comprises six master’s, twelve PhD and twelve postdoctoral fellows who concentrate their research endeavours on African, Imperial and Global History. All of these students are top achievers drawn from South Africa, Southern and Central Africa and even further afield. This group, now only in its third year, presents a phenomenal research output with an international reach.

In the course of the past year alone, five PhD students secured fully-funded invitations to conferences and research seminars in South Africa, Britain, as well as the Netherlands. Our researchers have been publishing articles globally and securing visiting fellowships and research awards.

Dr Clement Masakure and Dr Rosa Williams won funding to present papers at the International Network for the History of Hospitals. Tinashe Nyamunda won a prestigious three-month Cadbury Fellowship at the University of Birmingham in the United Kingdom. Anusa Daimon has been selected as a 2015 Harry Guggenheim award winner, which covers workshop attendance in Nairobi, Kenya.

From among the group, twelve articles have been published or accepted for publication in refereed scholarly journals, as well as four chapters in edited books. Book reviews written by these highly-motivated graduate students, have appeared or will appear in leading national and international academic journals. Remarkably, seven book reviews appearing in one particular issue of African Studies Review, were written by this group. Four scholarly monographs have recently been published, or soon will be. One PhD student is the joint editor (with a senior Canadian academic) of a forthcoming study on Zimbabwe’s controversial Marange diamond mining industry.

Another outstanding researcher, Dr Lindie Koorts, won the award for the best debut writer at the 2014 Woordfees for her book ‘DF Malan and the Rise of Afrikaner Nationalism’ – the first non-fiction writer to achieve this. Her book now appears on the longlist for the 2015 Alan Paton Award.
