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.

“I must congratulate the University of the Free State on doing something like this,” Dr Gansen Pillay said at the farewell function for the participants in the Southern African Young Scientists Summer Programme (SA-YSSP) at the UFS.

The 19 young scientists from 16 countries completed their three-month programme at the end of February 2013. As another step in the process the participants must write articles for reputable journals and complete their doctoral studies. Their performance in the research world will also be tracked.

Dr Pillay, deputy executive officer of the National Research Foundation (NRF), said an investment was made in the researchers to secure the future of the programme. A lot of persuasion and proof was necessary to convince the Austrian Institute for Applied Systems Analysis (IIASA) that a programme of this nature could be presented in Africa.

The SA-YSSP was hosted and managed by the UFS. The programme was developed by the NRF in collaboration with the Department of Science and Technology (DST) and IIASA into a novel and innovative initiative.  The official launch was by the Minister of Science and Technology during November 2011.

The SA-YSSP will be an annual three-month education, academic training and research capacity-building programme. Aligned with the YSSP model, annually presented in Austria, the SA-YSSP offered scientific seminars covering themes in the social and natural sciences, often with policy dimensions, to broaden the participants’ perspectives and strengthen their analytical and modelling skills, further enriching a demanding academic and research programme.

Prof Martin Mtwaeaborwa, SA-YSSP deputy dean, said the academic performance of the young scientists superseded the expectations. “I hope the scholars will look back at the programme as the moment their careers began.”

The added, “The UFS received positive remarks for organising the programme and we hope to get it again in future.”
