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.

The University of the Free State’s (UFS) Centre for Education Development (CED) has this week launched a project on the Main Campus in Bloemfontein.
to enable and encourage more learners to enter into science-related studies and careers.

The grant of R4,5 million over a period of three years was made by the South African National Roads Agency Ltd (SANRAL). This week’s function was attended by the representatives of the sponsors and the UFS, as well as learners, parents, principals and Physical Sciences teachers of participating schools.

The grant will be utilised to foster a positive attitude towards Mathematics and Science amongst learners in the early school years as well as raising the knowledge and skills levels of learners in the Further Education and Training (FET) Phase. “This will be done through our Family Math and Family Science Programme for younger learners and through e-Education in Science and Mathematics for learners in the FET Phase,” said Mr Cobus van Breda, Project Coordinator at the CED.

About 330 selected Grade 10, 11 and 12 learners from 16 schools in the Free State are attending Physical Sciences and Mathematics sessions during weekdays at the ICT Laboratories on the Main and Qwaqwa Campuses of the UFS. In order to make provision for the needs of generation Y-learners (techno-clever generation), the project envisages to enhance their understanding of Science and Mathematics principles by utilising the advantages of ICTs (Information and Communication Technologies) during the sessions.

On average, learners attend four sessions per term, with one of the sessions a special event like visiting Boyden Observatory, departments at the UFS, etc. Learners will be exposed to about 36 sessions over the three years. Special attention to vocational guidance, in collaboration with the Unit for Prospective Students at the UFS, forms part of the support system of the programme to participating learners.

“Learning is a life-long experience and we must encourage our learners to grab this opportunity to learn more about important fields such as Mathematics and Science. It is a privilege for SANRAL to have this partnership with the CED and the university as it is an indication of our efforts to educate our youth,” said Mr Nazir Alli, Chief Executive Officer of SANRAL.

Mr Alli encouraged learners to grab the opportunity to learn and to make the field of science their career. “Science can be the foundation on which to build your career and this programme can assist you to reach your goal,” he said.

According to Prof. Teuns Verschoor, Acting Rector of the UFS, the SANRAL grant is a wise investment because it is an educational investment. “We cannot cut back on the investments we make in education and SANRAL’s investment in this programme is of benefit to schools and learners in the central region. Through this programme, its bursaries, various career opportunities and ongoing support of schools and universities SANRAL is making a huge contribution to promoting science-related studies and careers in our country,” he said.
