Global Groundwater Information System

IGRAC Global Groundwater Information System (GGIS)Global Groundwater Information System (GGIS)

The Global Groundwater Information System (GGIS) is an interactive, web-based portal to groundwater-related information and knowledge. The main purpose of the system is to assist in collection and analysis of information on groundwater resources and its sharing among water experts, decision makers and public.

At this moment GGIS contains several modules/viewers, divided in the following six themes:  

  • Transboundary Groundwater, which contains all versions of Transboundary Aquifers of the World Map produced so far (with additional features and browsing functionality)  
  • Global Country Data, which provides a general review of the groundwater conditions per country, containing a set of aggregated groundwater-related attributes for each country.
  • Project Related Information, which contains all Information Management Systems (IMS) developed within the scope of projects such as TWAP and GGRETA.
  • Managed Aquifer Recharge, which contains the MAR Portal that shows a global inventory with site names, coordinates, MAR types and references.
  • Small Islands, which contains all SIDS (Small Islands Developing States) data collected within the framework of the TWAP project
  • Groundwater Monitoring, which gives insights on the availability of groundwater monitoring data through space and time.
