International Hydrographic Organization
The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the then member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, when a revision to the Convention on the IHO entered into force. Thereafter the IHB became known as the "IHO Secretariat", comprising an elected Secretary-General and two supporting Directors, together with a small staff of 17, at the Organization's headquarters in Monaco.
International Hydrological Programme
IHP’s activities are implemented by the efforts of its secretariat, located in UNESCO headquarters in Paris. The secretariat provides studies, information, and the facilities needed to employ the program’s activities. The backbone of IHP, however, is the network of National Committees. They are fundamental to ensuring the widest possible participation of Member States in IHP programs. The committees are run under the authority of National Governments and are responsible for implementing IHP initiatives.
