This PhD-project applies the triangle model of industrial ecology design to analyse specifically governance and institutions for fresh water innovation associated with selected technological innovations that are produced from other study as well as the interactions among water, energy and waste flow within selected Industrial Zones (IZs) and IZs with neighbourhoods in Vietnam. Within the framework of the research the institutional challenges are assessed by addressing the particular stakeholders through semi-structured expert interviews, document review and focus groups/workshops. In addition, based on synthesis of the data and insights, innovations in water reuse and multi-sourcing brackish water are identified. During this research there is contact between the technological and institutional stakeholders through workshops, focus groups, feedback sessions and other more individual meetings. This is a vital part of the research to guarantee the needed interaction and trans-disciplinary exchange of (new) knowledge and (new) insights.
