flood deficit Historical performance natural lake regulated history To reduce lake flooding Switzerland proposes the excavation of lake outlet to Italy.
Excavation design (with a model) Proposal Stakeholders Public consultation Political decision How was the excavation designed? Problem definition The classical planning approach The proposal was rejected!
Why? • Only lakeside population will take advantage of the excavation. • What about the others: • - riverside population
Why? • Only the lake side population will take advantage of the excavation? • What about the others: • riverside population: • fears that increasing the release rate will cause larger floods; • farmers: fear that increasing the release rate will cause more severe droughts.
Why? • Only the lake side population will take advantage of the excavation? 2.The proposal (and the design) comes from one of the two parties involved, the other one (Italy) does not trust it
Dredging design (with a model) Proposal Stakeholders Public consultation Political decision How was the excavation designed? Problem definition What to do? Get more interests involved: swap excavation for reservoir capacity Make participatorydecisions The proposal was rejected! The approach is wrong!!! The classical planning approach
Dredging design (with a model) Proposal Stakeholders Public consultation Political decision Negotiate on positions Negotiate on interests Problem definition Positions: I want to excavate I want a larger reservoir Interests: Avoid floods Reduce droughts

Dredging design (with a model) Proposal Stakeholders Public consultation Political decision Negotiate on positions Negotiate on interests To negotiate one needs to know the effects of the alternatives!

Write your final agreement on a piece of paper e.g. Satisfaction Upstream 43 Downstream 22 or No Agreement
Dredging design (with a model) Proposal Stakeholders Public consultation Political decision Negotiate on positions Negotiate on interests To negotiate one needs to know the effects of the alternatives 1) Use models to evaluate in a “participatory” process the impacts of each alternative; 2)start a “social learning process”; 3)by means of which an “acceptable compromise” can be found. Problem definition Interests: Avoid floods Reduce droughts Integrated Water Resources Management IWRM Positions: I want to dredge I want a larger reservoir
IWRM paradigm is adopted by EU • Water Framework Directive (WFD) • establishes a framework for the protection of all waters • requires within 2009 the production of River Basin Management Plans (RBMP) to be prepared following the IWRM paradigm WFD Art. 13
Integration • of environmental objectives; • of all water uses, functions and values into a common policy framework water for health and human consumption, water for economic sectors, transport, leisure, etc. • of all significant management and ecological aspects … including those which are beyond the scope of WFD, such as flood protection; • of stakeholders and civil society in decision making [WFD CIS GD11]
The WFD guidelines states: “planning is a process” and requires “to provide procedural guidance on the production and development of River Basin Management Plans” supported byappropriate toolboxes,that “should help to identify the possible trade-offs among quantifiable objectives so that further debates and analysis can be more informed”. Moreover the toolboxes must support “planning as a systematic, integrative and iterative process”.
Procedure Procedure IWRM: the need for a procedure Problem definition Excavation design (with a model) Stakeholders Political decision
Problem formulation Setting the goal and identifying the constraints Designing alternatives/options ICT Tools Selecting the best compromise alternative 6. Comparison or negotiation Mitigation, and compensation, no reasonable alternatives Agreement? yes Final (political) decision 1. Reconnaissance 2. Conceptualisation 3. Designing Alternatives 4. Estimating effects Stakeholders MODSS 5. Evaluation PIP procedure Participatory and Integrated Planning procedure
among which environmental objectives, e.g. “good water status” and “sustainable uses”, as required by the WFD. 1. Reconnaissance • System understanding • Stakeholders identification • System definition in time and space • Institutional and legal analysis • Setting up the Objectives Stakeholders

Problem objective Find a way of managing the lake that gathers a consent larger than the present one and enhances environmental quality (WFD requirements).
2. Conceptualisation Defining Actions (measures) 1. Reconnaissance Stakeholders
Farmers: change the regulation range Parks: improve environmental quality Lake manager: change the way the lake is presently regulated (regulation policy) Actions proposed by the stakeholders excavate the lake outlet Swisses: Italians:
