Region:
In recent decades over exploitation, pollution, and climate change have led to severe water
stress in locales across the world.
• 2.2 billion people lack access to safe drinking water.
• 4.2 billion people lack safely managed sanitation.
• Climate change is exacerbating the situation, with increasing disasters such as floods
and droughts.
• 80 per cent of wastewater in the world flows back into the ecosystem without being
treated or reused.
• 70 per cent of the world’s natural wetland extent has been lost, including a significant loss
of freshwater species.
Now more than ever the world needs to transform the way it manages its water resources and
delivers water and sanitation services for billions of people. Urgent action is needed to
overcome this global crisis.
