The World Bank Group Hydromet Expert Services Central Asia Project seeks to enhance regional cooperation for effective delivery of climate and hydrological services. To achieve this, the project requires guidance in assessing service gaps related to transboundary water management, in alignment with global frameworks such as the 2030 Agenda for Sustainable Development, the Sendai Framework for Disaster Risk Reduction 2015-2030, the Early Warning for All (EW4All) Initiative, and the WMO Guidelines and Recommendations. To ensure that the specific needs and priorities of each country are fully understood, the World Bank, with support from WMO, proposes to conduct National Capacity Assessments (NCAT) for five Central Asian countries. These assessments will focus on water resources, operational hydrology, and cryosphere issues, ensuring that CAHMP-II addresses both regional and national needs while aligning with local development priorities. The assessments will also map hydrological service delivery requirements and confirm the validity of previous evaluations to reflect the current needs of the region.
