The water scarcity at the heart of today’s global water crisis is often rooted in power, poverty, inequality and poor management (known as socio-economic water scarcity), rather than because demand for water exceeds supply (known as physical water scarcity). In the vast majority of cases the sector has been unable to extend access to water even where supplies are plentiful, which indicates the enormity of these socio-economic challenges. Although physical scarcity is not the main issue, it is increasingly having an impact. Pressure must be maintained on governments to fulfil their obligations to deliver WASH to all their citizens through increased access, but the sector must also recognise the growing threat that physical water scarcity poses to the goal of universal access to WASH by 2030. Governments and service providers must be prepared for the compounding effect that emerging physical water scarcity will have on existing socio-economic challenges.
