Global spatial database on water and agriculture

AquaMaps is the FAO global online spatial database on water and agriculture. It makes accessible through a simple interface regional and global spatial datasets on water resources and water management considered as a standard information resource, produced by FAO or by external data providers.

AquaMaps is complementary to AQUASTAT, FAO's Information System on Water and Agriculture. While AQUASTAT focuses on collecting mainly statistical data and qualitative information on (sub)country level, AquaMaps concentrates on geographical information. For most of the maps that have been generated by spatial modeling, Aquastat information has been used to calibrate and validate the model results.

AquaMaps builds on the FAO GeoNetwork data catalogue, from which it retrieves a thematic collection of layers, data and metadata, allowing users to query, explore, and download spatial data in commonly used GIS format.

The collection of dataset is organized by themes:

  • River and water bodies: regional hydrographic networks derived from Hydrosheds
  • Irrigation and infrastructures: area equipped for irrigation, dams
  • Hydrological basins: global and regional layers of hydrological basins derived from Hydrosheds
  • Climate: Monthly grids of precipitation and reference evapotranspiration
  • Models: output grid of FAO global soil water balance model (GlobWat), including modeled actual evapotranspiration, runoff and infiltration
  • Analyses: examples of global analyses performed on the basis of the above mentioned dataset.
