The water situation in the world

The situation in South Africa

The amount of water on Earth is constant and cannot be increased or decreased, but it is unevenly distributed across the planet. South Africa receives an annual rainfall of
492 millimetres per year, whereas the rest of the earth receives 985 millimetres.
This is nearly half the earth’s average.

Thus South Africa is classified as a water-stressed country.

There is also uneven distribution of rainfall across South Africa. The eastern half of the country is much wetter than the western half due to the nature of the weather conditions. South Africa also experiences alternating periods of droughts and floods which affects the amount of water across the country. In addition, hot, dry conditions result in a high evaporation rate. Scientists predict that with global warming, South Africa will experience much wetter wet seasons and much drier dry seasons, resulting in an increase in floods and droughts.

… and in the Western Cape

In the Western Cape, the demand will have exceeded the supply by 2019

The city of Cape Town has implemented level 3B water restrictions (level 4 from June, 1st)

On the 3rd of April 2017 , at the current consumption rate, there was only 100 days of water supply left for Cape Town.

As of May 2017, figures suggest dam levels to be at 11.2%
