ESPRES

ESPRES applies multi-objective optimization to select management strategies that balance water quantity (water flow) and water quality (nutrient concentration) objectives in European river basins and freshwater ecosystems.

Key Features:

• Multi-objective optimization (MOO): Integrates advanced multi-objective optimization (MOO) algorithms to evaluate competing environmental and effort objectives.
• Pareto front identification: Identifies Pareto front strategies representing trade-offs between environmental goals and required mitigation effort.
• Environmental objectives: Explicitly considers water quantity (water flow) and water quality (nutrient concentration) as target objectives.
• Perceived effort parameters: Incorporates parameterized perceived effort inputs including technical feasibility, political difficulty, and social acceptability.
• Scenario comparison and quantification: Compares multiple management scenarios and quantifies environmental impacts and socio-economic trade-offs.
• European-scale models: Leverages models developed at the European scale to assess outcomes of management options.

Scientific Applications:

• River basin management optimization: Selecting optimal management strategies for European river basins that balance water flow and nutrient concentration objectives.
• Trade-off evaluation: Evaluating trade-offs between ecological outcomes and socio-economic factors, including technical, political, and social effort.
• Pressure reduction prioritization: Prioritizing anthropogenic pressure reduction measures in European freshwater ecosystems.
• Scenario impact assessment: Comparing management scenarios to quantify environmental impacts and socio-economic trade-offs.

Methodology:

Applies advanced multi-objective optimization algorithms to identify Pareto fronts, uses parameterized perceived effort inputs (technical feasibility, political difficulty, social acceptability), compares management scenarios, and quantifies environmental impacts and socio-economic trade-offs using models developed at the European scale.
