Napoleon’s campaign to Moscow Poland 422000 Moscow 100.000 Poland 10000 Berezina500002800020° 28 oct
Outline • Introduction to the plan area • Evaluation of management alternatives • A virtual environment of the alternatives • Design of management alternatives • Use of maps for evaluation
Policy alternatives • Modern fen meadow (current) water drainage to support agriculture open landscape food for meadow birds • Historical fen meadow educed drainage raise of water table negative impacts for agriculture opp. for some bird and plant species • Dynamic mire floods in winter permanent waterlogged soils no agriculture peat growth
Stakeholders and their interests • Agricultural organisationsConstant water levels , water quality Accessibility, Size Continuity and future perspectives for farms • Recreation (fisheries)Variation in landscapes Accessibility Water quality • Nature Conservation Organisations Flexible water levels, water quality Variation in landscapes also cultural/historic landscapes Corridors, Larger units of protected nature • Provincial/regional authorities Safety Water quality Water quantity

Six Policy objectives Maximize totals 1.Maximize the natural value of the area, 2.Maximize the recreational value of the area, 3.Minimize cost of changing land use, Optimize spatial characteristics 4.Minimize fragmentation 5.Maximize cluster size, 6.Maximize compactness.
Spatial compactness Spatial compactness is defined as a combination of three indicators: fragmentation largest cluster compactness
How to use this system? • First round of policy design, scanning of alternatives • Preparation of land use and water management plans • Support of land use planners • Support of interactive processes
