Water Security in Australia

In the arid outback of the Australian state of New South Wales, the most famous waterway is the Darling River, highlighted in dark blue in this Proba-V image from November 2016. It flows from the northeast towards the southwest, where it will join the Murray River and head further towards the Great Australian Bight, near Adelaide.

In lighter blue, a series of freshwater lakes connect to the Paroo River that joins the Darling in the southwest of the image, near the historical village of Wilcannia. The area of the confluence of both rivers, along with Lakes Peery and Poloko, are part of the Paroo-Darling national park.

On the beds of the lakes, mound springs bring up fresh water from a vast acquifer that underlies almost 25% of the Australian continent, the Great Artesian Basin. This was an important water source for the indigenous Aboriginals and wildlife, but has more recently come under stress from competing uses, such as groundwater pumping for irrigation or mining.

Cape Town faces Day Zero

The beautiful Western Cape region in South Africa is naturally water-scarce. The historic dry spell, that started back in 2014, is now leaving water levels dangerously low.

The city of Cape Town, that is fed by water from six dams in and around the city, is imposing water restrictions to its citizens and visiting tourists. And measures are likely to become harder as Day Zero (currently expected in April) draws nearer.

Day Zero marks the day when dams fall below 13.5% capacity, so low that water taps to residential areas will be turned off and replaced by controlled water distribution at checkpoints.

These 100 m Proba-V images, comparing November 2014 with March 2017, clearly highlight the dramatic fall in water levels at three of the Big Six dams: Theewaterskloofdam (southern part of circle) and Brandvleidam & Kwaggaskloofdam that formed one impoundment in 2014, as the dividing ‘wall' between them was submerged. sports.
