Influences and actors at the interface between socio-technical and ecological systems - the case of on-site sewage systems

This research project aims at contributing with knowledge about influences on actors’ decisions and actions regarding on-site sewage systems. Such knowledge may be useful in planning and management processes supporting policy making regarding means and actions to mitigate marine eutrophication. This project focuses on the influences on actors situated at the interface between the sociotechnical and ecological systems; primarily house owners but also other actors with direct influence on nutrient loads; and secondary the actors with indirect influence on the actions taken “at the interface level” and can influence actions at the interface by e.g. policy or market actions. Using influence diagram approaches, a conceptual model will be developed, able to describe linkages between the local actors at the interface and a) the municipal administration and b) regional/national/EU institutions. The aim is also to initiate a formal modeling of the system. Based on interviews conceptual models of influences on actors at the interface are constructed. The formal modeling comprises the development of a simulation framework based on conceptual modeling and quantitative data from questionnaires.
