IHP anniversary

The UNESCO Intergovernmental Hydrological Programme (IHP), founded in 1975 following the International Hydrological Decade (1965-1974), is the only intergovernmental cooperation programme of the UN system dedicated to water research and management, and related education and capacity development. It addresses national, regional, and global water challenges, by supporting the development of sustainable and resilient societies.
