The pursuit of sustainable development and climate adaptation is increasing the demand for weather, climate, and water information and services to help protect lives and livelihoods from hydrometeorological hazards and optimize weather sensitive sectoral production. The core business of hydrological services is the provision of information about the water cycle and the status and trends of a country’s water resources. Most typically, this focuses on assessing water resources, including drought monitoring and outlooks and flood forecasting and warnings.
