Without water, there would be no life on Earth. Yet there is still significant inequality between those who have access to water and those that don’t.

This year’s World Water Week brings scientists, business leaders, policy-makers and community organisations together to tackle many of the world’s water issues. These are some of the things they will be talking about.

1. Only 0.5% of the earth’s water is suitable for human consumption
