Explanation:

GEO is a unique global network connecting government institutions, academic and research institutions, data providers, businesses, engineers, scientists and experts etc. to create innovative solutions to global challenges at a time of exponential data growth, human development and climate change that transcend national and disciplinary boundaries.

The unprecedented global collaboration of experts helps identify gaps and reduce duplication in the areas of sustainable development and sound environmental management.
Justification: GEO was established in 2005 as an intergovernmental mechanism for coordinating all existing and future Earth observations systems and implementing a “Global Earth Observation System of Systems” (GEOSS).
It is working to improve the availability, access and use of Earth observations.
It was launched in response to calls from the WSSD, the G8 and three ministerial Earth Observation Summits to improve existing Earth observation systems.
GEO now boasts over 1oo member countries and 45 participating organizations. It is constructing GEOSS on the basis of a 10-Year Implementation Plan that runs from 2005 to 2015. It is funded by voluntary contributions.
It aims to construct a global public infrastructure for Earth observations consisting in a flexible and distributed network of systems and content providers.
Ministers of the GEO member governments meet periodically to provide the political mandate and overall strategic direction for GEO.
