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.

Nation-building projects the focus of 26th Sophia Grey memorial lecture

This year, the University of the Free State’s (UFS’s) Department of Architecture had the privilege of hosting the renowned Phil Mashabane and Jeremy Rose from Mashabane Rose Associates as guest speakers at their annual Sophia Grey memorial lecture. 
 
Mashabane Rose is known for the numerous awards they won for their work on nation-building projects, such as the Hector Pieterson Museum, the Apartheid Museum, Lilliesleaf Museum, the Nelson Mandela House Museum and several other cultural and heritage projects. They also have the design of commercial, tertiary education, school, community and health projects on their record. 
 
“It isn’t only the visual side of architecture that is important to architects. It is also the story behind the story that matters,” Phil Mashabane said. 
 
“We used architecture to communicate history, as in the case of the Hector Peterson Museum. The building becomes the interpreting device to help people understand history,” Jeremy Rose said. 
 
“Good architecture is not only a product, but also a process,” Mashabane said.

An exibition of Mashabane Rose Associates' major projects can be viewed in the Oliewenhuis Art Museum for six weeks.
