Focus of presentation
-
Introduction: Integration needsGLOWA Elbe strives at giving scientific support for Integrated Water Resources Management (IWRM) in the Elbe River Basin, considering explicitly the potential impacts of global change.
The key element of IWRM is integration !
Integration needs
-
The key element of IWRM is integrationIn this context different forms of integration are needed:
Transdisciplinary integration of stakeholders and expert knowledge Integration of water policy fields: water quantity, water quality,floods
Integration of disciplines: finding links between natural and social sciences building up model systems Integration of results:support decision making in river basin managementIntegration needs: structure of the presentationIntegration needs
-
GLOWA II focuses on these five forms of integration:1. The Integrative Methodological Approach (IMA) the overall framework for integration in GLOWA Elbe2. The integration of stakeholders and expert knowledge transdisciplinary integration3. Integrated analysis of related water policy fields4. Integration of disciplines model integration5. Integration of results for decision support

1. IMA the overall framework of integrationIntegrative Methodological Approach of GLOWA Elbe (IMA)A) External boundary conditionse.g.,Climate Change and socioeconomic SRES B2 (Regionalisation)Climate Change and socioeconomic SRES A1 (Liberalisation)No climate change and .B) Policy optionse.g.,Introducing fertiliser chargesChanging priorities of water distributiontransferring water from other basins...

1. Implementation of IMA in research phases
-
Transdisciplinary integration has two meanings in the literature:
a)problem-oriented research with all important scientific disciplines involved trying to find appropriate approaches based on a mix or a synthesis of disciplinary approaches
b)involvement of decision makers, stakeholders and experts in order to transfer scientific results directly into society2. Transdisciplinary integration

Finding the missing link between water balance modelling and economic evaluationThere is no direct link between these two concepts !Needed: transfer functions to clarify the contribution of water availability to economic benefits (or: the vulnerability of water users to lacking water availability)

Finding the missing link between water balance modelling and economic evaluationTypical WBALMO result: Average yearly fulfilment of demand for different scenarios (in %, here: for industry in Upper Spree region)Starting period of touristic usewater treatment costsNeeded: transfer functions to clarify the contribution of water availability to economic benefits (or: the vulnerability of economic benefits to lacking water availability)

Two water management strategies with constant climate+ including climate change+ including socio-economic change (subsidy cuts, liberalisation)Average profits of fish farming, 2003-2052 (in mio. Euro of 2003, 2% discount)This means:fish farming is threatened by significant profit reductions - mainly caused by socio-economic and climate change !!!

Scientific support for IWRM requires multi-faceted forms of integration The IMA approach of GLOWA Elbe offers a framework to achieve this challenging task Important methodological tools and results emerge from this research (inclusion of economic analysis in water policy: Water Framework Directive)
