GEMS is a worldwide collective effect to monitor the global environment and make periodic assessments of the health of its constituents. Data are collected through monitoring and assessment activities covering most of the environmental parameters. One hundred and fortytwo countries participate in atleast one of these activities. The system involves the collaborations, of which the most important are the FAO, WHO, WMO, UNESCO and IUCN.
GEMS network monitor changes in atmospheric composition and the climatic system, freshwater and coastal pollution, air pollution, food contamination, deforestation, ozone depletion, the build up of greenhouse gases, acid rain, the extend of global ice cover and many issues related to biological diversity.
GEMS was first proposed in 1971 by the Scientific Committee on Problems
of Environment (SCOPE) later it was formally created in 1975, as a small
secretariat of UNEP.
During 1990's, GEMS took over a newer area of investigation i.e. early warning system for Environmental threats and disasters.
