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.

In 2006, the University of the Free State (UFS) signed an institutional agreement with the Autonomous University of Chapingo (UACH) in Mexico. This made the UFS the first South African academic institution to establish scientific relations with Mexico.

It was for this reason that Prof. Wijnand Swart, Director of the UFS Strategic Academic Cluster 4: Technologies for Crop Industries in Semi-arid regions, was invited to participate in the First Joint Subcommittee on Technical, Scientific and Technological Cooperation held recently in Mexico City. During his visit, Prof. Swart secured the working relationship between the UFS and the UACH.

During the first meeting of the Mexico-South Africa Bi-national Commission, the Mexican Foreign Secretary and Minister of Foreign Affairs and South African Minister for International Relations and Cooperation signed a joint statement. The statement, “Mexico and South Africa: Towards a Priority Relationship”, together with a Scientific and Technological Cooperation Agreement, will lay the foundations for monitoring existing collaboration and promote new actions between institutions in Mexico and South Africa.

Prof. Swart spent the remainder of his stay in Mexico presenting lectures to staff and students at the UACH on integrated pest management and challenges facing South African agriculture. He also engaged in discussions with Dr Gisela Pena-Ortega, Director of the UACH Office for International Affairs and Academic Exchange, about the establishment of a staff and student exchange programme with the UFS.
