The results of the project were published in relevant international and referred journals. Moreover the results were presented at national and international scientific congresses. The research project was intended to support dissertations on this topic.Workplan: Based on quantitative and qualitative preparations, the project uses a "stated preference" survey in order to analyse discrete choices in households. Subsequently, sustainability strategies were deduced and examined for their ecological, economic and social impacts.
