Hydrogeology
The hydrogeology map below shows a simplified version of the type and productivity of the main aquifers at a national scale (see the Aquifer properties resource page for more details).
More information on the hydrogeology of Madagascar is available in the report UN (1988) (see References section, below).
Groundwater management
There was information on more than 3,000 water boreholes across the country, in 2009. Geological logs for the boreholes are not available. There was no information about large diameter wells.
