Description: Das Projekt "Integrating GIS and Remote Sensing for Multi-Scale Analysis of Degradation in the African Sahel" wird vom Umweltbundesamt gefördert und von Technische Universität Dresden, Fakultät Forst-, Geo- und Hydrowissenschaften, Institut für Photogrammetrie und Fernerkundung, Bereich Fernerkundung-Geoinformatik durchgeführt. Multi-level monitoring of destabilized Sahelian regions connects field work in situ with detailed to semi-detailed analysis of vegetation structure (aerial photography), vegetation functional types and units of rational landcover (satellite images). Human impact on Sahelian vegetation in its regional variations is a main reason for continous destruction of former grazing lands. Regional dynamics of impact patterns are analysed by means of multi-stage remote sensing techniques and multi-spectral image classification. Integration of remotely sensed as well as of socio-economic data with geo-information systems is an important tool for modelling regional dynamics of degradation and desertification due to multi-thematic and multi-temporal input parameters. Intersection of geo-informations creates change detection databasas of Sahelian regions. Planning sustainable development will urgently need the appropriate use of the presented facilities of IGIS technology.
