Monitoring and information sharing
“Far too little is understood in regards to the true state of the world’s freshwater assets. We can’t handle what we don’t measure,” Ms. Saulo said.
“This report seeks to contribute to improved monitoring, data-sharing, cross-border collaboration and assessments. That is urgently wanted,” she added.
WMO mentioned the report seeks to boost the accessibility and availability of observational information, via higher monitoring and improved information sharing, significantly within the World South.
Early warning
The report aligns with the main focus of the UN’s international Early Warnings for All initiative in addressing water-related challenges.
The worldwide effort goals to enhance information high quality and entry for water-related hazard monitoring and forecasting, with the aim of offering Early Warning techniques for all by 2027.
The WMO has emphasised the pressing want for motion to deal with water-related challenges, calling for improved monitoring, information sharing and cross-border collaboration to raised perceive and handle international water assets.
