In the documentary 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?’”
TechKnow is a series exploring how the latest scientific and technological discoveries are changing our lives.
