Priority Needs for the Operationalization of the Global Framework for Climate Services (2016–2018)
The global community is rapidly putting in place measures to protect societies from adverse socioeconomic and environmental impacts caused by extreme weather-, climate- and water-related events, and also to take maximum advantage of any positive benefits of these changes that may exist. However, many projects are being undertaken in isolation, in the absence of mechanisms for alignment of the diverse efforts being made at project level, and without conforming to relevant international standards. This can result in duplication of efforts, which may prove unsustainable or ineffective in the long ...
