The objective of the project is to support oasis management on the Tarim River in Xinjiang Province, Northwest China, against the background of socio-economic changes and climate change. Within this framework, a decision support system (DSS) will be developed in cooperation with Prof. Dr. Kern (Chair of Knowledge Management and Business Process Design) as the main result of the project, which will enable a Sustainable Impact Assessment by the regional planning authorities. The perspectives of all relevant actors and decision makers in the field of land and water management along the Tarim River are taken into account. Based on the sustainability analysis, scenarios are set up and the semi-quantitative assessment of their impacts is carried out. In the implementation phase, the Chinese partners will be extensively trained in the use of the tools developed.
