Description (résumé)

Public participation is an effective way to resolve the tensions between contested objectives, while maintaining ecological integrity. New Zealand is one of the few countries that takes a collaborative approach to environmental management, mandating that management plans for catchments are co-created with local communities based on the concept te Mana o te Wai. The National Policy Statement for Freshwater Management (NPS-FM) gives guidelines on objectives and attributes that must be considered to safeguard freshwater values. They also specify minimum quality standards, but allow communities to set higher standards and to add more objectives. A critical challenge in this process is to successfully account for potentially conflicting objectives in a framework that supports decision-making. Little guidance on this is provided in the NPS-FM, which leaves the challenge to the Regional Councils to overcome. In my talk I present a participatory decision support framework based on multi-criteria decision analysis (MCDA) that allows the weaving together of different values, objectives and, therefore, different ways of knowing. I illustrate how we implemented the MCDA-framework to develop a catchment management plan for the Upper Clutha catchment in Central Otago. Finally, I talk about what lessons we have learnt that help foster the successful application of the MCDA-framework in other catchments across New Zealand, and worldwide in decision-making situations that want to be inclusive.
