Cooperation with International Organizations
The IAEA works with many other international organizations to
implement its programme on water resources:
The Global Network for Isotopes in Precipitation (click here for
figure 13) is
maintained in collaboration with the World Meteorological
Organization (WMO), with which the Agency also collaborates on
Global Atmosphere Watch Programme.
Regional and global problems associated with fresh water
are carried out in cooperation with the UN Environment Program
(UNEP), the World Health Organization (WHO) and the UN Economic
Commission for Africa (UNECA).
Close cooperation is maintained with in the International
Biosphere Programme (IGBP), the Global Environmental Monitoring
System (GEMS), the Global Climate Observing System (GCOS) of WMO
and Earthwatch of UNEP.
Training programmes are conducted and results published together
with UNESCO under its International Hydrological Programme (IHP).
Cooperative efforts with UN Food and Agriculture Organization
and other UN bodies allow food security, soil erosion and
sedimentation concerns to be addressed.
Special interagency linkages have been created to address the
pressing environmental problems of the rapidly rising Caspian
The IAEA-WMO Global Network for Isotopes in Precipitation
Interpretation of the isotopic composition in terrestrial water
requires knowledge about the meteoric water that feeds them: rain
and snow. Their isotopic composition is quite variable in time
space, and depends on climate, geography, nuclear fallout and
The need for comprehensive global information was recognized many
years ago, when the IAEA, in cooperation with the World
Meteorological Organisation (WMO), launched the World Survey of
Isotopes in Precipitation Network in 1961. The Survey, now called
the Global Network for Isotopes in Precipitation (GNIP) has grown
increasingly important in studies of the environment and climate
change. (Click here for figures 11 -
The results of this survey, as well as statistical analyses, are
published regularly in the Technical Report Series of the IAEA.
