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.

Multitudes celebrate dr Beyers Naude's selfless life
2013-09-14

26 September 2013

The lecture was held in partnership with the diverse churches, the youth, the house of traditional leadership. The theme was Love for Humanity.

In his special message to the gathered religious leaders, students and staff, Apostle Saki Thapong, challenged all in attendance to “look for your own miracles within yourself.”

“We need a generation of miracles and not a generation of people running after miracles”, said Apostle Thapong.

“Allow your miracle to manifest itself within you and never look at your own miracle through your own time, but through God's time and purpose”, Pastor Thapong said.

In focusing on the choice of the theme, Vice-Rector: External Affairs, Dr Choice Makhetha, said that the theme was very important to all stakeholders who needed to pledge their commitment to building a community of people who care deeply about the safety of its children and senior citizens.

“As stakeholders in the Thabo Mofutsanyana District Municipality, we need to collectively build a society courageous enough to dirty its hands to shape the socio-economic development of this area, for the benefit of the local people, the country and the world. We must build a community of people who work tirelessly to ensure that the dignity of every human being is restored and protected, especially women,” said Dr Makhetha.

Previous speakers in the series include, Dr Allan Boesak, Prof Kwandiwe Kondlo, Dr Frank Chikane, Mr Johann Naude (Dr Naude's son) and Prof Jonathan Jansen.

Dr Beyers Naude was an ordained minister in the Dutch Reformed Church who stood against apartheid despite his advantaged Afrikaner background. In the aftermath of the Sharpeville Massacre of March 1960, 'Oom Bey' started questioning the morality of the government's policies. At the time of his passing away in September 2004, he was described as a “true humanitarian and true son of Africa” by Nelson Mandela.
