Visualization-supported dialogues in the Baltic Sea Region.

This study explores visualization-supported dialogues with water management and ecosystem stakeholders from four catchments in Sweden, Latvia, Germany and Poland. An interactive visualization tool was designed to present information regarding modelled effects of chosen future pathways including different measures that address ecosystem issues under present and future scenarios of land use and climate change, and estimated benefits and costs of the measures. This paper assesses if and how visualization-supported dialogues hinder or support key components of good governance of water and ecosystem management among expert stakeholders. We discuss challenges and opportunities related to the tool and dialogue design, and performance of dialogues. Results from a cross-case workshop indicate that the form and functionality of the tool contributes to participation, empowerment, accessibility and flexibility, while dialogue design is instrumental for encouraging trust and inclusion of local knowledge and competence.
