Water as short resource
Water is vitally important. Water shortage is a big challenge in many regions. At first view, this is astonishing, because 70% of the earth’s surface is covered by water. There are totally 1.4 quadrillion liters of water (1.400.000.000.000.000), from which more than 97% is salt water. There are less than 3% fresh water, from which more than two third are bound in ice and glaciers. The biggest of the fresh water is the ground water. Usually, this is available in sufficient quantities.
People mainly use to live in regions with good water supply. As a consequence, water shortage can be seen in the summertime, e.g. in South European countries: Water has to be saved in order to guarantee a basic supply.
Europe has a per-capita-consumption of 100 – 250 liters per day. Already nowadays, more than two billion people have access to less than 50 liters per day. More than 800 million people do not have access to sufficiently clean potable water (World Water Development Report, WHO). It is expected that in 2050, 44% of the earth population will not have sufficient access to potable water. The change of climate (increasing temperatures, changing rainfall, rinsing sea level) will getting even worse in the next decades. Worldwide, 884 million people do not have access to sufficiently clean potable water.
As a result of a study by the Technische Universität Berlin, 70% of the consumed water is used in agriculture. For the production of food & water is of essential importance. For the production of 1 kilo tomatoes 80 liters are needed, for the production of 1 kilo bread 1000 liters are needed, and for the production of 1 kilo lamb over 10000 liters are needed. Therefore, anno 2050, many countries in Europe, Asia and Africa are expected not being able to sustain their own population without the import of food. Countries like India or Central Africa have the opportunity to expand area of arable land.
Also for industry, water is of high importance. For the production of 1 jeans 8000 liters are needed, for the production of 1 tonne of paper between 500000 and 1500000 liters are needed up to the used technique (www.wasserstiftung.de, 2011).
We offer custom-made solutions to challenges in the fields of water supply and water storage. Additionally, we can provide fresh water from our ten drinking-water springs in the Andes.
