The International Hydrological Programme (IHP), a UNESCO’s intergovernmental scientific co-operative programme in hydrology, is a vehicle through which Member States can upgrade their knowledge of the water cycle and thereby increase their capacity to better manage and develop their water resources. It is the only intergovernmental programme of the UN system devoted to the scientific, educational and capacity building aspects of hydrology. | UNESCO’s international hydrological programme and contribution of Viet Nam to the programme
