German stamp about the general meeting of the International Union of Geodesy and Geophysics in 1983

The International Union of Geodesy and Geophysics (IUGG; French: Union géodésique et géophysique internationale, UGGI) is a non-governmental organisation dedicated to the scientific study of the Earth and its space environment using geophysical and geodesic techniques.

The IUGG was established in 1919.[1] Some areas within its scope are environmental preservation, reduction of the effects of natural hazards, and mineral resources.


IUGG objectives are the promotion and coordination of studies related to Earth's physical, chemical and mathematical representation. This includes geometrical shape, internal structure, gravity and magnetic fields, seismicity, volcanism, hydrologic cycle, glaciers, oceans, atmosphere, ionosphere, and magnetosphere of Earth; and also solar, lunar and planetary studies.[2]


The IUGG consists of eight semi-autonomous associations:[3]

It has also established five commissions to promote interdisciplinary problems:[4]

  • Climatic and Environmental Changes (CCEC)
  • Mathematical Geophysics (CMG)
  • Geophysical Risk and Sustainability (GRC)
  • Study of the Earth's Deep Interior (SEDI)
  • Data and Information (UCDI)
