Climate

Koppen Geiger Climate ZonesAverage Annual PrecipitationAverage Temperature

Average monthly precipitation for Madagascar showing minimum and maximum (light blue), 25th and 75th percentile (blue), and median (dark blue) rainfall Average monthly temperature for Madagascar showing minimum and maximum (orange), 25th and 75th percentile (red), and median (black) temperature Quarterly precipitation over the period 1950-2012 Monthly precipitation (blue) over the period 2000-2012 compared with the long term monthly average (red)

More information on average rainfall and temperature for each of the climate zones in Madagascar can be seen at the Madagascar climate page.

These maps and graphs were developed from the CRU TS 3.21 dataset produced by the Climatic Research Unit at the University of East Anglia, UK. For more information see the climate resource page.

Surface water
Major surface water features of Madagascar. Map developed from World Wildlife Fund HydroSHEDS; Digital Chart of the World drainage; and FAO Inland Water Bodies. For more information on the map development and datasets see the surface water resource page.

Soil

Soil Map of Madagascar, from the European Commission Joint Research Centre: European Soil Portal. For more information on the map see the soil resource page.

Land cover

Land Cover Map of Madagascar, from the European Space Agency GlobCover 2.3, 2009. For more information on the map see the land cover resource page.


Geology

The geology map on this page shows a simplified version of the geology at a national scale (see the Geology resource page for more details). More information is available in the report UN (1988) (see References section, below).


Geology of Madagascar at 1:5 million scale. Developed from USGS map (Persits et al. 2002). For more information on the map development and datasets see the geology resource page.

Hydrogeology

The hydrogeology map below shows a simplified overview of the type and productivity of the main aquifers at a national scale (see the Hydrogeology map resource page for more details).

More information on the hydrogeology of Madagascar is available in the report United Nations (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.


Transboundary aquifers

For further information about transboundary aquifers, please see the Transboundary aquifers resources page.

References

References with more information on the geology and hydrogeology of Madagascar can be accessed through the Africa Groundwater Literature Archive.
