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.

“This new development will strengthen the long-lasting collaboration between DiMTEC and the United Nations University, Institute for Environment and Human Security (UNU-EHS) in Bonn in Germany. This [collaboration] goes back for almost a decade of joint training courses and increasingly also includes collaboration in the frame of scientific projects, especially in Africa.”

These were the words of Dr Joerg Szarzynski after his appointment as Affiliated Associate Professor to the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS). Dr Szarzynski will assume his new position with immediate effect.
 
The United Nations University (UNU) is a global thinktank and postgraduate teaching organisation headquartered in Japan.

Dr Szarzynski, head of the EduSphere section and Education Programme Director at UNU-EHS, brings with him a wealth of experience, including serving as senior expert to the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER). Within the team, he was principal desk officer for Africa responsible for relief activities after natural disasters, technical consultation, information management, collaborative network development and the cluster on health and climate change adaptation. He also has broad expertise in climatology and remote sensing, global environmental change research, capacity-building and web-based data and information management.

“Dr Szarzynski’s appointment brings
new research opportunities.”

Lecture focus on vulnerability and disaster risk reduction
As part of his new academic responsibilities, Dr Szarzynski will conduct face-to-face lectures during a course on vulnerability and disaster risk-reduction. With this course the centre aims to increase awareness of the complexity and importance of vulnerability and resilience in the field of disaster risk management. Dr Szarzynski’s teachings will focus on Early Warning Systems and Geospatial Technologies in Support of Disaster Risk Reduction (DRR) and Emergency Response Preparedness. He will also lead courses on Assessment and Coordination in International Disaster Management and Humanitarian Response and Information Technology in Disaster Risk Reduction and Disaster Management.

Furthermore he will give lectures via distance learning for the wider curriculum at DiMTEC.

Collaboration between DiMTEC and UNU
Dr Andries Jordaan, Director of DiMTEC at the UFS said: “His appointment opens new networks within the United Nations system, which brings new research opportunities. Furthermore, his expertise is important to us. He has already provided input and delivered lectures through Skype in the course of Information Technology and Communication.”

Dr Szarzynski has been lecturing for the past 10 years in the UFS’ international PhD curriculum.
