Al Jazeera highlight: TechKnow - The Science of Water Sustainability

TechKnow on Al Jazeera

In The Science of Water Sustainability, TechKnow explores three solutions for water scarcity that don’t involve waiting for rain: fog-catching nets, intelligent watering and washing machines that use 80% less water.

The Western Cape is hardly the only place facing a water crisis: a United Nations report suggests that water consumption has grown twice as fast as population growth. By 2025, it’s estimated that two-thirds of the world’s population will live in water-stressed regions.

“Our entire system of living was based upon a paradigm of plentiful water,” Dr Daniel Fernandez, a professor of natural sciences at Cal State Monterey Bay, tells TechKnow. “It wasn’t considered: ‘What if we need to use less?’”

The Science of Water Sustainability premieres on TechKnow on Al Jazeera on Saturday, 22 April 2017 at 2230 GMT/2330 WAT and Sunday, 23 April 2017 at 0030 CAT and 0130 EAT. The full episode will be available to watch and embed from YouTube after it airs.
