The UNESCO Intergovernmental Hydrological Programme (IHP) was established in 1975, evolving from the International Hydrological Decade (IHD) which spanned from 1965 to 1974. The IHD was a pivotal global initiative aimed at enhancing the understanding of hydrological processes and water resources management. Following its success, the IHP was launched to continue and expand upon these efforts.

Historical Background

International Hydrological Decade (1965-1974) The IHD was a coordinated global effort to advance hydrological research and address water management issues. This decade of intensive research laid the groundwork for international collaboration in hydrology and significantly contributed to the scientific understanding of water cycles, distribution, and management.

Inception of IHP (1975) Building on the foundations of the IHD, the IHP was created as the first intergovernmental programme dedicated exclusively to water research and management within the United Nations system. Its main goals were to foster sustainable water resource management, enhance scientific understanding, and develop capacity in water-related fields through education and training.

Evolution and Expansion Over the years, the IHP has grown to address various emerging challenges in the hydrological sciences. The programme has expanded its focus to include integrated water resources management, climate change adaptation, and the sustainable development of water resources. Through its various phases, IHP has facilitated international cooperation and provided a platform for countries to collaborate on water-related issues, sharing knowledge and best practices globally.

Key Phases and Achievements

• IHP-I (1975-1980): Focused on improving the understanding of hydrological processes and advancing basic research.
• IHP-II to IHP-V: Gradually incorporated aspects of water resource management, education, and policy development.
• IHP-VI (2002-2007): Emphasized water interactions and focused on interdisciplinary approaches to water management.
• IHP-VII (2008-2013): Addressed water scarcity, quality, and sustainable water management.
• IHP-VIII (2014-2021): Concentrated on water security and responses to local, regional, and global challenges.
• IHP-IX (2022-2029): Current phase, emphasizing science for a water-secure world in a changing environment, with a focus on innovative solutions and transdisciplinary approaches.

Throughout its history, IHP has played a crucial role in shaping global water policies and advancing the scientific understanding of water resources. It continues to support member states in achieving sustainable water management goals, contributing to global efforts towards the United Nations Sustainable Development Goals (SDGs), particularly SDG 6, which aims to ensure availability and sustainable management of water and sanitation for all.

The mission of the UNESCO Intergovernmental Hydrological Programme (IHP) is to advance water security through international cooperation in hydrological science, education, and capacity-building. This involves fostering sustainable water resource management, enhancing scientific knowledge about water systems, and promoting policies and strategies that address global, regional, and national water challenges. The IHP aims to support the development of resilient societies by integrating scientific research, innovation, and the practical application of water management techniques.
