Many countries are currently facing droughts and water shortages, and this is not good at all because the human being cannot live without water, neither can the fauna and flora on earth.
Although there is still the exact same amount of water on earth as what there always has been, there are far more people and far more things water is being used for, such as industry, agriculture, and energy.
It is estimated that the majority of the world could experience perennial water shortages by as soon as 2025, according to and a leading expert on hydro climatology, climate change adaptation, and risk analysis, Dr Upmanu Lall, who is also the director of the Columbia Water Centre.
This means that in a world of around seven billion people, approximately four to five billion will not have access to freshwater for consumption, for growing or preparing food, or for generating electricity.
Water shortages mean devastation for some countries, especially in poorer regions where the staple diet is maize, wheat or rice, and especially if there is a water shortage in regions that grow these products. A 10% decrease in global production of wheat or rice due to drought translates into a 50% increase in global prices. This may not mean much for richer countries, but will mean starvation for third world countries.
It is vital that each country looks after its own freshwater resources and the infrastructure that delivers this water because wastage cannot be tolerated. The climate is changing, which means that areas that were getting minimal rain before are now getting even less; some areas that had good rainfall are experiencing flooding and others are now experiencing devastating droughts.
While all governments need to ensure that they look after the water in their countries, every citizen needs to also do their bit to conserve, recycle and reuse water where necessary. Remember, the human body is made up of around 70% water, so if there is no water to drink you will die!
