Got water?

 

Climate change and rising demand are making it harder to meet the world’s water needs. At World Water Week, the OECD will join experts, political leaders and civil society to look at how we can better manage this vital resource.

 

Water is a powerful element – essential for sustaining life but also capable of causing great destruction. As a result, governments face the dual challenge of protecting water supplies while safeguarding against the risk of natural disaster.

 

It’s not an easy task. Governments around the world face significant challenges in managing their water resources effectively. The problems are multiple and complex: billions of people are still without access to safe water and adequate sanitation; competition for water is increasing; and major investment is required to maintain and improve existing water infrastructure.

 

The need to reform water policies is as urgent as ever. According to the OECD Environmental Outlook to 2050, global water needs are projected to increase by some 55% due to growing demand from manufacturing, thermal electricity generation and domestic users. As a result, more than 40% of the world’s population is projected to live under severe water stress by 2050. At the same time, nearly 20% will be exposed to flood risks.

 

OECD work on Water provides governments with practical advice and policy tools to pursue urgent reform in their water sectors, and help align the world to a more sustainable path.
