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.

UFS Extraordinary Professor involved in public signing of historic charter
2010-10-27

Prof. Iain Benson

Prof. Iain Benson, an Extraordinary Professor in the Department of Constitutional Law and Philosophy of Law at the University of the Free State (UFS), was one of the speakers at the signing of the historic South African Charter of Religious Rights and Freedoms on Thursday, 21 October 2010.

Thursday’s signing of the charter was the culmination of two years’ work of the Continuation Committee responsible for drawing up the document, of which Prof. Benson is a part. All the major religions signed the charter at the ceremony Thursday where Prof. Benson was one of the four speakers, who included the Deputy Chief Justice of South Africa, Justice Moseneke.

The charter, which has already received considerable international and national attention, will now be submitted to the ANC government for negotiations. Indicative of the important role that Prof. Benson played in the process of drawing up the charter is that he has been offered a role as an advisor for the newly created committee responsible for the drafting of the Constitution of the Council of Religious Freedom.

Originally hailing from Canada and currently residing with his family in France, Prof. Benson is an academic with a wealth of experience and expertise in the field of law, especially with regard to right of conscience and religion. His achievements number many, including being a Senior Associate Counsel at one of Canada’s leading law firms, Miller Thompson LLP; and serving on the Founding Board of the Global Centre for Pluralism. Prof. Benson gave his inaugural lecture last week with a lecture entitled Living together with Disagreements and the Limits of the Law.
