Participatory floodplain management in the Red River Basin, Canada

Floodplain management is a subject in which everyone in the floodplain is a stakeholder. Real participation only takes place when stakeholders are part of the decision-making process. This can occur directly when local communities come together to make floodplain management choices or if democratically elected or otherwise accountable agencies or groups can represent stakeholders. Real participation is more than consultation and requires that stakeholders at all levels of the social structure have an impact on decisions at different levels of floodplain management. A participatory approach is the only means for achieving long-lasting consensus and common agreement. However, for this to occur, stakeholders and officials from water management agencies have to recognize that the sustainability of floodplain management decisions is a common problem and that all parties are going to have to sacrifice some desires for the common good. There is common responsibility for making participation possible. This involves (a) the creation of mechanisms for stakeholder consultation at various scales (from local, over watershed to national) and (b) the creation of participatory capacity, particularly amongst marginalized social groups. This may include awareness raising, confidence building and education, as well as the provision of the economic resources needed to facilitate participation and the establishment of good and transparent sources of information. This work focuses on the methodology for stakeholder participation in floodplain management. Floodplain management problems are characterized by multiple objectives and large number of stakeholders. The solution methodologies adapted for multi-criteria multi participant decision problems are generally based on aggregation of decisions obtained for individual decision makers. This approach seems somewhat inadequate when the number of stakeholders is very large. We have developed a methodology to include the views of multiple stakeholders using fuzzy set theory and fuzzy logic. Three possible different response types: scale (crisp), linguistic (fuzzy), and conditional (fuzzy) are analyzed to obtain the resultant input by using Fuzzy Expected Value. Fuzzy Expected Value input is used with the multi-criteria decision-making tool named Fuzzy Compromise Programming. The methodology has been applied to floodplain management in the Red River Basin, Canada that faces periodical flooding. We have demonstrated that the empowerment of stakeholders can improve the floodplain management process and provide decisions acceptable to a wider group of stakeholders. # 2006 Elsevier Ltd.
