2 Content 1.GLOWA-Elbe: Two Topics for One Basin in Three Phases 2.Principal Approach 3.Challenges for GLOWA-Elbe 4.Product Line 5.Our Invitation to stakeholders

3 1. GLOWA-Elbe: General Objective: Adjustment of water management strategies to global change Topics: Surface water quality Surface water quantity Phases: Exploration of the basin Solutions for the basin Transfer of Tools (confirmed by BMBF) involving Czech partners and institutions

4 Content 1.Two Topics for One Basin in Three Phases 2.Principal Approach 3.Challenges for GLOWA-Elbe 4.Product Line 5.Our Invitation to stakeholders

5 2. Principal Approach 1 Scenario 2 Indicators & criteria 3 Impact 4 Evaluation Addressing Society Deficits Perception Evaluation Objectivity for Sustainable Development

6 Content 1.GLOWA-Elbe: Two Topics for One Basin in Three Phases 2.Principal Approach 3.Challenges for GLOWA-Elbe 4.Product Line 5.Our Invitation to stakeholders

7 . Challenges - Uncertainty Beside others - Wet or Dry climate change? - Discounting of future benefits? (typical between 3 and 5%, Nordhaus 0.1 %) Adaptation strategies have to be beneficial in the near future under current and future climate
