Africa - Hydrological Basin Boundaries (FAO)

River network of Africa derived from the WWF HydroSHEDS drainage direction and stream network layers at 15 arc-second resolution. Includes major rivers, tributaries and stream networks with basin and sub-basin attribution, Strahler stream order, and upstream area. Use this layer for hydrological analysis, water resource mapping, flood risk assessment, infrastructure planning near waterways, and environmental impact studies across Africa. No additional information provided.

This dataset divides the African continent in major hydrological basins and their sub-basins according to its hydrological characteristics. It was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data (WWF HydroSHEDS and Hydro1K). The dataset consists of the following information:- numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); - area of the major basin in square km (MAJ_AREA); - numerical code and name of the sub-basin (SUB_BAS and SUB_NAME); - area of the sub-basin in square km (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea) **Data publication:** 2021-12-15 **Supplemental Information:** This dataset is developed as part of a GIS-based information system on water resources for the African continent. It has been published in the framework of the AQUASTAT - programme of the Land and Water Division of the Food and Agriculture Organization of the United Nations. **Contact points:** Metadata Contact: [AQUASTAT](mailto:aquastat@fao.org) Resource Contact: [Jippe Hoogeveen](mailto:jippe.hoogeveen@fao.org) **Data lineage:** The linework of the map was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data with a resolution of 15 arc-seconds.The elevation dataset was part of a mapping product, HydroSHEDS, developed by the Conservation Science Program of World Wildlife Fund.

This dataset was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data (HydroSHEDS and Hydro1K). Input data resolution is 15 arc-seconds between 60 N and 60 S latitude (based on SRTM), and 30 arc-seconds for higher latitudes (based on GTOPO30). The dataset consists of the following information: numerical code (MAJ_BAS), name (MAJ_NAME) and area (MAJ_AREA) of the major basin in square km. **Data creation:** 2011-02-02 **Supplemental Information:** This dataset is developed as part of a GIS-based information system on water resources. It has been published in the framework of the AQUASTAT - programme of the Land and Water Division of the Food and Agriculture Organization of the United Nations. The map is also available in the SOLAW Report 15: “Sustainable options for addressing land and water problems – A problem tree and case studies”. **Citation:** Food and Agriculture Organization of the United Nations, FAO Land and Water Division.

Original input data had been obtained during NASA's Shuttle Radar Topography Mission (SRTM). Areas north of the SRTM extent, 60 degrees N, were obtained by merging with the HYDRO1k basin layer. **Resource constraints:** This product "Major hydrological basins of the world" incorporates data from the **HydroSHEDS** database which is © World Wildlife Fund, Inc.

SDG 6 Foundation Basin Units (SDG6-FBU). The SDG6-FBU is a geo-spatial data layer with spatial information derived from HydroBASIN level 12 (https://www.hydrosheds.org/products/hydrobasins). Each of these small hydrological units (approximately 1 million basins) is named according to the ‘SDG 6 Major Basin’ and ‘SDG 6 Sub-Basin’ classification, with the sub-basins nested within the major basins. **Data publication:** 2025-05-02 **Supplemental Information:** The dataset is included as part of Geo-Spatial Information collected and published in the framework of the AQUASTAT - programme of the Land and Water Division of the Food and Agriculture Organization of the United Nations. https://www.fao.org/aquastat/ **Citation:** Integrated Monitoring Initiative for SDG 6 (IMI-SDG 6), SDG6 Basin Maps, Foundation Basin Units, Latest update: 31/07/2024.

The SDG6-FBU is a geo-spatial data layer with spatial information derived from HydroBASIN level 12 (https://www.hydrosheds.org/products/hydrobasins). Each of these small hydrological units (approximately 1 million basins) maintains attribute information from the following 4 source layers: • FAO (major basins and sub-basins) • TWAP (river basins component) • GRDC (river basins) • WMO (major basins and sub-basins), which allows for backward compatibility to be maintained to each source layer. In addition, each hydrological unit will be named according to the new ‘SDG 6 Major Basin’ and ‘SDG 6 Sub-Basin’ classification, with the sub-basins nested within the major basins. These new SDG 6 classifications will draw initially upon the source layers and then over time be revised based on country information. All improvements of the SDG 6 Basin Map will be conducted in this layer.
