Desalination to secure water supplies: A problematic solution?

One out of nine people in this world still don’t have access to safe drinking water, and a global water crisis is just around the corner. To solve the problem, more and more countries and regions are turning to desalination - converting seawater into drinking water - to secure their water supplies.

Desalination is bringing clean water to millions. But despite technological breakthroughs, it remains an energy-consuming process and can be harmful to the environment.

Today, there are close to 19,000 desalination plants in the world and Saudi Arabia has most of them; processing some 12 million cubic meters of water a day.
