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.

"Participation without insight leads to pronouncements without prospects"
2004-08-30

Taking the poor off the streets and encouraging their participation in the planning process is not always empowering them but it might be robbing them of their power, said Prof Das Steyn, of the Department of Urban and Regional Planning at the University of the Free State (UFS).

Speaking on public participation in the planning process during his inaugural lecture, Prof Steyn said this meant that people in the streets sometimes have more power than people in the system.

“Public participation is an overgeneralization that is often defined as providing citizens with opportunities to take part in governmental decisions and planning processes. But there must be a balance between power and responsibility,” he said.

According to Prof. Steyn, public participation in town planning plays a vital role and can be both deliberation and participation.

After 1994 there was a widespread insistence on democracy, and legislation passed since then was based on the belief that the community must be involved in the planning process.

He said the experience of the Department of Urban and Regional Planning at the UFS was that in some cases people showed lack of interest in public participation.

He believed that the aim of public participation is to improve the effectiveness of planning and that public participation democratises project planning.

“Public participation can help us know how the public feels about certain issues. It has the potential of resolving a conflict, but this is not guaranteed,” Prof Steyn said.
