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.

Research and court cases confirm that the trade in people is a reality in South Africa. According to Dr Beatri Kruger from the Unit for Children's Rights and the Department of Criminal and Medical Law at the University of the Free State (UFS), complex challenges are faced in combating human trafficking. One of these challenges is a lack of knowledge of this crime and the difficulty in identifying trafficked victims.

To address the lack of knowledge, a number of discussions took place between Dr Kruger and delegates from the Department of Health.

A project has been initiated to address this problem in the public health sector. A need to raise awareness and provide training to medical practitioners to better understand human trafficking was identified. The most important aim of this initiative is to empower medical staff, to identify trafficked victims that visit hospitals and clinics countrywide and to also treat them appropriately in light of the severe trauma they have often been exposed to. The initiative will also empower medical practitioners to refer patients to other service providers such as social workers and psychologists.

The talks with medical practitioners from the Department of Health have led to training and awareness raising that will be provided at some of the local hospitals before the end of the year. Further training seminars are planned for medical practitioners, which will include a presentation by Dr Kruger on legal issues that are relevant for staff in the public health sector. The multidisciplinary cooperation that was established between representatives from the UFS Faculty of Law and the Department of Health has contributed substantially to a more effective response to human trafficking in South Africa.
