Better coordination between bilateral, multilateral and private sector investments in water data and tools could provide synergies and reduce unnecessary spending.An example in the water sector are the long-operting data centres federated within the GTN-H that offer a long-term commitment to global (mostly) in-situ water observations (some of them since decades). Their data are widely used by scientific communities. Of course there are many more examples, in particular from space agencies and space-borne observations.- Can external funding for monitoring and capacity building help to encourage beneficiaries to share data with the data centres and the global community to address local and global problems? - Are there best practice examples of how this is a long-term benefit of external funding from which nations benefit?- What are good ways to monitor the impact of observational networks, databases or data sets for decision-making and capacity development? 

Facilitating the development and implementation of open tools and standards for managing and exchanging water data within and between organizations at sub-national, national and international levels could support water management and policy making at various levels.Please share your experience about, e.g.- (un) successful implementation of international standards for data transfer (e.g. OGC WaterML-2. netcdf-CF), or the FAIR Data principles, GEO Data Sharing and Management Principles- good practice examples of shared tools- How to enhance skills development and availability of shared data
