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.

A launch for the much-anticipated book by Dr Christian Williams from the University of the Free State (UFS) was sponsored by the Humanities Center and the Center for African Studies of Stanford University in the USA, among others.

The launch of the book, National Liberation in Postcolonial Southern Africa: A Historical Ethnography of SWAPO’s Exile Camps, coincided with the 40th anniversary of Angola’s independence.

The book was published by Cambridge University Press in September 2015, and the launch at Stanford was on 16 November 2015.

This groundbreaking study, which will be available in South Africa early next year, has already been lauded for its invaluable contribution and the depth of its scholarship. The author is a senior lecturer in the Department of Anthropology of the UFS, and member of the Vice-Chancellor’s Prestige Scholars Programme (PSP). He is a former Fulbright scholar, and holds a doctorate from the University of Michigan in History and Anthropology.

National Liberation in Postcolonial Southern Africa follows members of the South West Africa People's Organization (SWAPO) through three decades of exile in Tanzania, Zambia, and Angola.

It highlights how different Namibians experienced exile, as well as the tensions that developed within SWAPO as Namibians encountered one another while officials asserted their power and protected their interests.

It also follows the return of Namibians who lived in exile to post-colonial Namibia, examining the extent to which divisions and hierarchies that emerged in the camps still continue to shape Namibians today.
