Abstract:
Against a background of changing ecological, economic and social framework conditions in this joint research project bases of knowledge and of decision-making shall be developed for an innovative and sustainable land use management in the North German Lowland. Based on major landscape types state of actual situations and interrelationships shall be analysed and scenario based developments shall be estimated for four exemplary model regions, Furthermore intercollegiate and transdisciplinary adaptation strategies shall be deduced and their effects shall be measured by trans-sectoral indicators of a sustainable land use management. To perform these tasks a nested approach will be developed and applied. The model regions are situated on a transect from Diepholz in the West, via Uelzen in the Lüneburger Heide, via the Fläming in the East of Sachsen-Anhalt and in the South-West of Brandenburg, respectively, up to the region Oder-Spree in the East. They indicate natural geographical, structural, economic and demographic gradients. The aspects „Ecological Basics“, „Land Use and Resource Utilization“, „Operational and Regional Value Creation“ and „Risk Management“ shall be elaborated by recognised scientists from
the domains of climatology, hydrology, landscape ecology, agriculture, forestry, environmental planning and socio-economics. By means of transdisciplinary methods the aspects shall be consolidated into a concept for an „Integrative Land Use“.
 
Tasks and Objectives:

  1. Situation analysis of landscape water balance and matter balance as well as of water and mass flows of the selected representative basins (conflicts, indicators) in conjunction with measurement campaigns (4 regions) 
  2. Elaboration of scenarios for the future development of water balance in consideration of changes of regional spatial conditions and of management strategies (specification by the partners) 
  3. Model specific adaptation of SWAT in particular  consideration of vulnerable elements of landscape water balance 
  4. Prediction of changes of landscape water balance due to climate and land use changes and prediction of the related changes of the quality of water bodies by means of scenario based simulations 
  5. Provision of model results for the utilization in other models developed for selected model farms as well as for decision support  to solve potential conflicts of interests (land use, resources)
