Senegal Desertification Hazard Model

New-ID: NBI163 The Senegal Desertification Hazard (model) documentation File: SENEGAL7.IMG Code:146008-001 Raster Member The IMG file is in IDRISI format The Senegal Desertifcation Hazard was originally digitized for the UNEP/FAO/ESRI Database for Africa provided by FAO for the Desertification Hazar Mapping project. GRID-Geneva rasterized the coverages for UNEP/GRID/WHO/CISFAM Senegal Database with a cell size of 30 seconds and two minutes lat/lon (approximately one- and four kilometeter-square pixels, respectively). The model was developed using many of the preceding (SENEGAL1-6) as well as several additional data layers, by means of an iterative process and according to a FAO-provided model. Soil constraints, wind and water action, soil salinization, human and animal population pressure on the landscape were all considered in the final model.
