Résumé
This work illustrates the scientific application of satellite remote sensing and GIS methods for the optimization of irrigated agricultural lands in the Amu-Darja lower course and in its delta area. Major goal is the reduction of the agricultural water demand through alternative land use models and the creation of a monitoring instrument for the ecological development of the region. Within this framework the development of the Geographical Information System as well as the methods for information extraction from satellite data of various geometric and temporal resolution will be demonstrated. As a prerequisite for potential substitution measures for the conventional water-intense crops cotton and rice by alternative cultures the physical-geographical and economical conditions of the region will be analyzed. In addition the water demand as well as the appropriate agricultural site potential will be determined. The applied methodologies (Multi-Criteria-Evaluation, water transprt costs, etc.) will be explained in detail. Finally an overview of the implementation of the GIS will be given as well as an outlook concerning the future extensions of the system
