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.

Degree in Forensic Science for 2014
2013-08-16

16 August 2013

A BSc degree in Forensic Science will be presented for the first time at the University of the Free State (UFS) from 2014. It is also the first degree of its kind to be presented in South Africa.

According to the Department of Genetics in the Faculty of Natural and Agricultural Sciences the three-year degree is, among others, aimed at people working on crime scenes and on criminal cases in the SA Police Service and in forensic laboratories. At postgraduate level, students can specialise in a variety of forensic fields up to PhD.

A maximum of 80 students will be selected for admission to the course in 2014. Entrance requirements are an admission point of at least 34, as well as a combined minimum point of 17 for Mathematics, Life Sciences and Physical Science. Applications for 2014 close on 30 September 2013. About 700 to 800 new appointments were advertised in this field by the SAPS in the past two years.

The UFS has been offering an honours programme in Forensic Genetics since 2010.

The new course comes at a time when the Government is taking significant steps to eradicate crime in South Africa. At the first conference of the SA Police Service’s National Forensic Service in July 2013, it was reported that milliards of rand are spent to establish an integrated, modernised, well-manned and well-managed criminal justice system. New laboratories are already operational and more laboratories are planned, including one in each province.

The so-called DNA Bill is likely to be approved by Parliament before the end of 2013. Under this bill, all current schedule-1 criminals and suspected criminals will be obliged to provide DNA samples. This information will be stored in a DNA database.

According to the SAPS’ Serial Unit, approximately 1 300 serial killers are currently active in South Africa and the DNA database can be helpful to bring these and other criminals to book. About 80% of all crimes are committed by about 20% of the criminals.

More information on the Forensic Science degree can be found at forensics@ufs.ac.za or +27(0)51 401 9680 or +27(0)51 401 2776.
