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.

Invitation to International Cardiothoracic congress
2011-06-01

Our Faculty of Health Sciences is pleased to announce the European Association for Cardiothoracic Surgeons Academy (EACTS) and Hannes Meyer Cardiothoracic Surgery Registrar Symposium, which will be taking place on our Bloemfontein Campus from 3 to 5 June 2011.

The congress first started in 2004 as the Hannes Meyer Registrar Congress, which was jointly hosted by the UFS and the Society of Cardiothoracic Surgeons of South Africa. This event was hosted on our Bloemfontein Campus annually, except in 2009, when the University of Cape Town was the host.

The focus of this year’s symposium is new techniques in perfusion and surgery, with specific emphasis on research methodology, inflammatory lung disease and cardiac surgery in children and adults, which can be performed without the aid of a heart-lung machine in developing countries.

Prof. Francis Smit, Head of the Department of Cardiothoracic Surgery in the Faculty of Health Sciences, says EACTS identified the UFS as the Sub-Saharan training unit they will support in terms of training. The first of these symposiums was accordingly hosted in 2010.

This year’s symposium will be attended by approximately 70 delegates from cardiothoracic units from across South Africa and 10 doctors from 6 African countries, as well as 30 perfusion technologists.

“We are fulfilling a leadership role in Africa and South Africa with this course,” says Prof. Smit.

Several international visitors will be present, like Prof. Paul Sergeant and Prof. Marko Turina, two previous EACTS presidents and Prof. Charles Yankah, a Ghanaian Cardiothoracic Surgeon from the Charite Medical University in Berlin. The current president of the European Board of Cardiovascular Perfusion (EBCP), Mr Frank Merkle, will also be one of three international speakers delivering lectures on perfusion technology.

You are invited to attend the conference on the following dates:

 
Date: 3 - 5 June 2011

Time: 09:00

Venue: Faculty of Health Sciences in the Francois Retief Building on our Bloemfontein Campus
