A formal model for consensus and negotiation in environmental management.

Area of Science:

• Environmental Science
• Public Policy
• Decision Science

Background:

• Environmental management decisions involve diverse stakeholders with competing interests.
• Ad hoc consensus methods often lead to suboptimal or contested outcomes.
• Formal methods are needed for transparent and repeatable decision-making in environmental management.

Purpose of the Study:

• To demonstrate the utility of a mathematical consensus convergence model for aggregating stakeholder values.
• To provide a formal framework for consensus building in environmental decision-making.
• To compare the consensus convergence model with existing ad hoc methods.

Main Methods:

• Application of a mathematical consensus convergence model to an environmental management case study.
• Aggregation of stakeholder values (weights) using the consensus model.
• Comparison of the model's outcomes with traditional consensus-building approaches.

Main Results:

• The consensus convergence model successfully aggregated diverse stakeholder values into a single consensual value.
• The model demonstrated transparency and repeatability in the decision-making process.
• The formal model offers advantages over informal, ad hoc methods for conflict resolution.

Conclusions:

• Mathematical consensus convergence models provide a robust and transparent decision support tool for group decision-making.
• The model guarantees convergence towards a consensual group position, even without full agreement.
• Formal consensus models are recommended for environmental management scenarios with multiple stakeholders.
