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 Council of the University of the Free State (UFS) unanimously reappointed Dr Khotso Mokhele as Chancellor during its quarterly meeting held on 13 March 2015. He was first appointed in this portfolio by the Council on 4 June 2010.

“It is an honour for the Council to reappoint someone of this stature as Chancellor of the UFS. With his solid academic background and high profile in the business world, Dr Mokhele has been a great asset to the UFS. On behalf of the Council and the university community, I extend a word of appreciation for the work he has done during his first term as Chancellor of the UFS. He is an exceptional leader, and the university community is looking forward to have him as Chancellor for a second term,” said Judge Ian van der Merwe, Chairperson of the UFS Council.

Dr Mokhele was awarded a BSc Agriculture from Fort Hare University, and continued his studies at the University of California Davis (USA) on the Fulbright-Hays Scholarship Programme, completing his MSc (Food Science) and PhD (Microbiology). He was subsequently a postdoctoral fellow at Johns Hopkins University School of Medicine (USA) and the University of Pennsylvania School of Medicine (USA). Dr Mokhele is the recipient of honorary doctorates from nine South African universities including the UFS, and from Rutgers University in the USA.

He was Chairman of the Rhodes Scholarship Selection Committee for Botswana, Malawi, Namibia, Lesotho and Swaziland (2007-2011), and served on the South Africa at Large Rhodes Scholarship Selection Committee for more than 10 years. As President and Chief Executive Officer (CEO) of the Foundation for Research Development (1996-1999) and the NRF from 1999 to 2006, Dr Mokhele played a central role in providing visionary and strategic direction to the South African science system. He was the Founder President of the Academy of Science of South Africa (ASSAf), Founder President and CEO of the National Research Foundation (NRF), Chairperson of the Economic Advisory Council to the Premier of the Free State (2001-2004), and a member of the Advisory Council on Innovation to the Minister of Science and Technology (2003-2007). His role in securing government and international support for the Southern African Large Telescope Project (SALT) is evidence of his dedication to science in South Africa. The success of this project laid the basis for South Africa being selected to host more than 70% of the Square Kilometre Array, an international mega telescope for radio astronomy.

In recognition of his contribution to the development of science, he was the recipient of the Technology Top 100 Lifetime Achievers Award in 2009 and the National Science and Technology Forum Award in 2005. His role in science is recognised internationally. He was an elected Vice-President: Scientific Planning and Review of the International Council for Science and Chairperson of its Committee for Scientific Planning and Review (2005-2008) as well as a member of the Committee on Developing and Transition Economy Countries of the International Social Science Council (2008-2010). He also represented South Africa on the executive board of UNESCO, and was awarded the Member Legion of Honour of the Republic of France for his work in strengthening scientific ties between South Africa and France.

Dr Mokhele currently serves as Special Advisor to the Minister of Science and Technology, the Honourable Naledi Pandor. His current corporate positions include: Non-Executive Chairman: Board of Directors, Impala Platinum Holdings Ltd (Implats); Lead Independent Non-Executive Director: African Oxygen Ltd (Afrox); Non-Executive Director of Zimbabwe Platinum Holdings Ltd (Zimplats); Hans Merensky Holdings Ltd; and Tiger Brands Ltd. He is the President of the Hans Merensky Foundation (South Africa) and a Trustee of SciDev.Net (a web-based scientific magazine based in London, UK) and Start International Inc (USA).
