"Planning for Day Zero

After a third consecutive year of drought, Cape Town residents have been asked to reduce their water consumption to 50 litres a day. If reservoir levels drop below 13.5 per cent capacity, the taps will be turned off, forcing people to collect a maximum daily ration of 25 litres from one of 200 sites.

Snowfall in the Rocky Mountains is the source of water for tens of millions of people across North America. "The water from this mountain range flows into the Arctic Ocean and the Pacific and the Atlantic, so what happens here matters for the whole continent," says John Pomeroy, a hydrologist who has been studying the snowpack for nearly 15 years.

Disappearing glaciers

In the past, glaciers provided a reliable source of water that could feed rivers in times of drought, but the warming climate has shrunk icefields in places like Glacier National Park in Montana, which contains the headwaters of the Milk River in Alberta.

Water levels in the Dead Sea, between Jordan and Israel, have been dropping by more than a metre a year.
