We have thorough knowledge of the water resources of our world

Collecting, managing and sharing data on water resources and their use are fundamental for a better understanding of these resources, and for developing appropriate water management solutions, informing the decision-making process from local to global scale. 

The sixth of the eight long-term ambitions on water aims at ensuring that we have thorough knowledge of the water resources of our world, as foreseen in the WMO Vision and Strategy on Hydrology.

An appropriate monitoring system, addressing all the key variables associated with operational hydrology including the cryosphere, should span the globe and produce information that can be used to optimize the efficiency of existing services, future policies, services, and political decision-making from the local to the global scale. 

Further development of WMO initiatives matched with other international efforts should enable local and global assessments of the availability of water resources.
