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.

International speakers unite to discuss diversity
2014-01-20


The Institute of Reconciliation and Social Justice is hosting a two-day colloquium on 30–31 January 2014. A broad range of keynotes will discuss the topic: ‘Diversity and the politics of engaged scholarship: A comparative study in higher education’.

Prof Jonathan Jansen, Vice-Chancellor and Rector, and Prof Dr Halleh Ghorashi from the Netherlands will lead as keynote speakers on the first day.

Prof Dr Ghorashi is a Professor of Diversity and Integration in the Department of Sociology at the Vrije Universiteit Amsterdam. She is the author of ‘Ways to Survive, Battles to Win: Iranian Women Exiles in the Netherlands and the United States’. She has also published extensively on topics such as identity, diasporic positioning, cultural diversity and emancipation.

During the second day, Dr Charles Alexander from Los Angeles and Prof Shirley Tate from Leeds will lead as keynote speakers.

Dr Alexander is Associate Vice-Provost for Student Diversity at the University of California. He has run several programmes for students who have been underserved by higher education, including students from immigrant families and underrepresented populations. In 2011, Dr Alexander received a Champions of Health Professions Diversity Award from The California Wellness Foundation in recognition of his commitment to increasing California’s health care workforce and its diversity.

Prof Shirley Tate’s work focuses, among others, on theorising ‘race’ performativity and the intersection between 'race' and gender. She has written on mixed ‘race’ identities, affect, beauty, embodiment, pain and women in prison, transracial intimacies, gendered prison identities, racial affective economies in organisations, as well as on domestic work and food.

The sessions led by these keynote speakers are open to the public and the Institution welcomes everyone to join in this topical discussion.

Date: Thursday 30 January 2014 and Friday 31 January 2014
Time: 09:00–11:00
Place: Centenary Hall
