Global Environment Facility
        - “The Global Environment Facility (GEF) unites 182 member governments — in partnership with international institutions, nongovernmental organizations, and the private sector — to address global environmental issues.  An independent financial organization, the GEF provides grants to developing countries and countries with economies in transition for projects related to biodiversity, climate change, international waters, land degradation, the ozone layer, and persistent organic pollutants.”

    Global Water Partnership
        - “The Global Water Partnership's vision is for a water secure world. Its mission is to support the sustainable development and management of water resources at all levels.”

    International Programme on the State of the Ocean
        - “IPSO's unique consortium of scientists and other Ocean experts — including those from the legal, communications and political arenas — identify the current problems, project the future outcomes of these problems and develop workable solutions to alter the trajectory of degradation.”

    International Rivers
        - “International Rivers' mission is to protect rivers and defend the rights of communities that depend on them. We oppose destructive dams and the development model they advance, and encourage better ways of meeting people’s needs for water, energy and protection from damaging floods.”

    International Water Association
        - “The International Water Association (IWA) is the global network of 10,000 water professionals spanning the continuum between research and practice and covering all facets of the water cycle.”

    The Water Supply and Sanitation Collaborative Council
        - “The Water Supply and Sanitation Collaborative Council (WSSCC) is a global multi-stakeholder partnership and membership organisation that works to save lives and improve livelihoods. It does so by enhancing collaboration among sector agencies and professionals who are working to improve access for the 2.6 billion people without safe sanitation and the 0.9 billion people without clean drinking water.”

    World Glacier Monitoring Service
        - “Today, the World Glacier Monitoring Service (WGMS) collects standardized observations on changes in mass, volume, area and length of glaciers with time (glacier fluctuations), as well as statistical information on the distribution of perennial surface ice in space (glacier inventories). Such glacier fluctuation and inventory data are high priority key variables in climate system monitoring; they form a basis for hydrological modelling with respect to possible effects of atmospheric warming, and provide fundamental information in glaciology, glacial geomorphology and quaternary geology.”

    World Meteorological Organization
        - “The World Meteorological Organization (WMO) is a specialized agency of the United Nations.  It is the UN system's authoritative voice on the state and behaviour of the Earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.”

    World Water Council
        - “The World Water Council was established in 1996 in response to increasing concern from the global community about world water issues. Its mission is to promote awareness, build political commitment and trigger action on critical water issues at all levels, including the highest decision-making level, to facilitate the efficient management and use of water in all its dimensions and on an environmentally sustainable basis."
