Wetland Assimilation for Climate Change Adaptation: A Decision Analytic Approach

The Wetland Assimilation Feasibility Planning Multi-Criteria Decision Model utilizes an analytic holistic approach to assess the feasibility and planning process of wetland assimilation for wetland restoration, tertiary treatment of wastewater, and climate change adaptation for the New Orleans region. Multicriteria decision theory was used to integrate aspects of wetland assimilation ecological and engineering design with aspects of sustainable development, urban planning, and public health. Simple Multiattribute Rating Technique (SMART) was used to assess the value trade-offs of stakeholders composed of governmental and policy decision makers, science and technical experts, industry representatives, environmental advocates, and citizen stakeholders. The results of the decision model will enhance the analysis of wetland assimilation as an alternative, prioritize actions and resources, and facilitate inclusion of aspects that are currently not included in water resource decision making. The tool can also be used to identify gaps in planning, understanding, and stakeholder consensus, in addition to providing a method for public involvement.
