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.

Dr Mercy Oduyoye receives an honorary doctorate for changing how women are viewed in theology

Dr Mercy Amba Oduyoye received an honorary degree from the UFS Faculty of Theology in acknowledgement of the trailblazing work she has done in the field of African women’s theology. Known as the Mother of African Women’s Theology, Dr Oduyoye is the first black woman in Africa to have received a degree in theology. Ever since then, she has been changing views on gender in theology across the globe. Still at the office at the age of 82, Dr Oduyoye’s life work has centred on two areas: her work with churches, and her work with female theologians.

Women in religion and culture
Following the 2015 Winter Graduation Ceremony on the Bloemfontein Campus, during which Dr Oduyoye received her honorary degree from the University of the Free State (UFS), she presented a lecture on women in religion and culture at the Faculty of Theology. Dr Oduyoye gave a brief overview of her involvement in organisations since the early 1970s to eliminate patriarchal structures in theology, in order to produce a relationship of partnership between women and men. An area that lies especially close to Dr Oduyoye’s heart is that of storytelling, and the use of language. Therefore, a driving force behind her work has been the question: “How do we communicate what we believe as Christians?”

Writing in a way people can understand

This question led Dr Oduyoye on her journey to vernacularise theological language, and it became her mode of writing. “Very seldom will you find the classical or official theological language in my writing, because I’m writing as if I’m speaking to a youth group, a women’s group – or even my grandmother.” In this way, communication became her focal point to present Christianity in such a way that people can understand it, thus rendering it relevant to the situation in Africa.

Changes toward inclusive language
Dr Oduyoye has gone on to author four books and over eighty articles on theology from a feminist perspective. And after toiling for many years, Dr Oduyoye can now see the changes emerging – especially in the US – as Bibles, lectionaries, and hymns are increasingly adopting an inclusive language, giving women a presence and voice within the church.
