Spatial dataset derived from many different open data repositories and cropped on the Omo-Turkana Basin boundary, used to create a base-map describing the components of Water-Energy-Food nexus in the case study. omo-turkana.gpkg: vector dataset including the following layers, together with the related map style for QGIS Desktop used in the DAFNE Geoportal basemap: basin: Hydrological basin of the Omo-Turkana river (case study boundary) subbasin: Basins of the main tributaries waterbodies: Natural lakes and reservoirs boundaries rivers: River network dams: Existing dams protected_areas: Protected areas aei_pct_cells: Area equipped for irrigation, expressed as percentage of total area. roads: Main roads network cities: Main cities in the riparian countries countries: Administrative borders of riparian countries markers: DAFNE model components location, with existing and planned dams and power plants, irrigation schemes, environmental target areas. zambezi_raster.zip: raster dataset including the following layers: srtm_90m: Digital Elevation Model Global Surface Water: change: Occurrence Change Intensity map provides information on where surface water occurrence increased, decreased or remained the same between 1984-1999 and 2000-2015 extent: Maximum Water Extent shows all the locations ever detected as water over period 1984-2015 occurence: Occurrence shows where surface water occurred between 1984 and 2015 and provides information concerning overall water dynamics. recurrence: Recurrence provides information concerning the inter-annual behaviour of water surfaces and captures the frequency with which water returns from year to year. seasonality: Seasonality map provides information concerning the intra-annual behaviour of water surfaces for a single year (2015) and shows permanent and seasonal water and the number of months water was present. transitions: Transitions map provides information on the change in surface water seasonality between the first and last years (between 1984 and 2015) and captures changes between the three classes of not water, seasonal water and permanent water. Original data sources include: AQUASTAT, the FAO global information system on water resources and agricultural water management; Natural Earth, a public domain map dataset available at different scales; Protected Planet, the most up to date and complete source of data on protected areas and other effective area-based conservation measures, maintained by UNEP-WCMC and IUCN; OpenStreetMap, a collaborative project to create a free editable map of the world; NASA's Shuttle Radar Topography Mission (SRTM) Digital Elevation Database; Global Water Surface, a virtual time machine that maps the location and temporal distribution of water surfaces at the global scale.
