2 Robustness Analysis OSeMOSYS Uncertainties: Response Strategies: Changes in ClimateChanges in PopulationChanges in LanduseResponse Strategies:Add infrastructure (e.g. desalination)Improvements in system efficiencyWastewater reuseDemand ManagementOSeMOSYSIterative, analytic process designed to identify strategies that are robust to a wide range of planning uncertainties.Outcome Metrics:Delivery reliabilityUnmet demandsHydropower generationGroundwater & surface water storage
3 Recall also that the “XLRM” Framework support participatory scoping and analytical design Uncertainty Factors (X)Response Packages/Policy Levers (L)Uncertain factors outside of the control of water managers which form the basis of scenarios analysis.Management strategies available to water managers:Current systemPlanned strategiesModels (R)Performance Metrics (M)Models to produce metrics of performance (M) for each strategy (L) in the face of ensembles of uncertainties (X)Results of interest, metrics used to evaluate the performance of strategies under consideration
4 Factors of Uncertainty(X) Performance Metrics (M) Uncertainties (X)Factors of Uncertainty(X)Response Packages (L)What uncertain factors, outside the control of water managers, may affect water management outcomes?What is the plausible range for such uncertainties?What information is needed to define these ranges and any best estimates?Who has the information?Models (R)Performance Metrics (M)
5 Performance Metrics (M) Factors of Uncertainty (X)Response Packages (L)Models (R)Performance Metrics (M)What characteristic of system performance are important to you? What are the measures and indicators that we should use to evaluate these characteristics? What are the acceptable levels and limits of this measures and indicators to be achieved? What is the information needed to define these acceptable levels and limits? Who has the information?
6 Response Packages (L) Factor s of Uncertainty (X) Response Packages/Policy Levers (L)Are there additional projects that we should include in the base line?What types of response packages in addition my potentially address the impacts of climate change?Models (R)Performance Metrics (M)
7 Factors of Uncertainty (X) Performance Metrics (M) Relationships (R)Factors of Uncertainty (X)Response Packages (L)Models (R)Performance Metrics (M)Based on what you heard yesterday about our tools and approaches, what advice would you have for improving the modeling that will be use to support the analysis?
