Over 80 per cent of countries have reformed their water laws in the past twenty years as a response to growing pressures on water resources from expanding populations, urbanization and climate change.
In many cases, such water reforms have had positive impacts on development, including improvements to drinking water access, human health and water efficiency in agriculture.
But global progress has been slower where irrigation, rainwater harvesting and investment in freshwater ecosystem services are concerned.
These are among the findings of a United Nations survey of over 130 national governments on efforts to improve the sustainable management of water resources. The survey was specifically produced to inform decision-making at Rio+20.
The survey focuses on progress towards the implementation of internationally-agreed approaches to the management and use of water, known as Integrated Water Resources Management (IWRM).
