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.

Listen to Dr Abuelaish's public lectures (audio)

In 2009 Israeli forces bombed the house of Palestinian doctor Izzeldin Abuelaish killing four people: three of his daughters and a niece. Speaking about this life-changing event, Dr Abuelaish delivered two public lectures at the University of the Free State (UFS) this week spreading the message of hope and peace.

Dr Abuelaish, who was introduced as the Nelson Mandela of Palestine by Prof. Jonathan Jansen, Vice-Chancellor and Rector, spoke emotionally about the loss of his daughters Bessan, Aya and Miyar.  He told the audience that there was no reason for them to be killed. His girls were armed with love, hope and education.

He urged people to have moral courage and encouraged them to strive for justice, truth and peace. When there is justice and truth, peace is a consequence. “As a medical doctor I never lose hope. By the end of this world we will forget what enemies did, but will never forget the silence of brothers.”

Dr Abuelaish spoke passionately about the role of women in society and said a country develops by how much it invests in women’s education. “We must realise the strongest members in a community are women. Women maintain the hope.”

Speaking about his life in the war, being born Palestinian, Dr Abuelaish said it was painful to hear that Palestinians are numbers and statistics. “When a soldier is killed in Iraq or another place, the screen speaks for days about what he ate and what he hoped for, others are figures and numbers.”

Dr Abuelaish, who wrote the book I shall not hate, A Gaza Doctor’s Transformational Journey of loss, Love and Change, said the death of his daughters made him stronger and more focused not to give up. “I swore to my daughters and God not to rest, I fully believe I will meet them one day. I will meet them with the big gift of justice.”
