Although Australia is known for being the world＇s driest inhab-ited continent, water scarcity is hardly an issue that is isolated to just one country. In recent months, the prolonged drought in South Africa has led to a water crisis that prompted real and urgent warn-ings that Cape Town, the country＇s second-largest city, faced the possibility of running out of water. In India, the northern summer has brought on a repeat of acute water shortages, with reports of taps running dry in many areas and with one policy think-tank warning that around 600 million people in India are facing water stress.
