"In the year 2002, under the sponsorship of La Spezia Port Authority, a coastal area has been analyzed in order to correlate the environmental health with the people environmental perception. The aim of the study, called the OASIS Project, was to set up a management tool for the freezing of the conflicts between the different anthropogenic activities located in the area. The area under examination is the Ligurian coast around the Gulf of La Spezia (Italy). This area is characterized by several conflicting activities (commercial marine traffics, port, industrial facilities, fishing, aquaculture, tourism and marine protected parks). The tool for the management outlined by the project was an Observatory capable to monitor many different sensitive parameters both ecological, social, economical in relation with the psychological perception of the quality of life. The tool envisaged is an interpretation model operated by mathematical routines and expert evaluations able to predict the eco-system and people reaction to environmental perturbations. The study outlined that the environmental perception, connected to environmental survey was a very important parameter to be considered, so the correlations between people environmental perception of the eco-system perturbations and/or the eco-system evolution had to be considered together.The tool, for what the people perception is concerned, has to be a measure of the “Quality of Life” consisting in the balance between personal objectives and interests and collectively accepted standards. The measure of the Quality of Life is performed through what is called "Social Capital", a parameter cluster as: sense of community, collective efficacy or empowerment, citizen participation and so on. Further more conventional parameters related to the material well-being, are to be considered:This method of evaluation of the Quality of Life has never been applied before to contexts as defined before. It has been applied in different contexts (Edmondson R. (2003) Hawe P., Shiell A. Perkins D., Brown B., Taylor R.B. (1996) (2000), Marsdsen D. e Oakley P.(1990). The aim of the paper is to present the methodology in order to collect comments from a very expert community before starting the project. The Observatory will consist of the selection of a significant group of citizens to whom submit, periodically, series of questionnaires to evaluate the evolution of the perception with time. The questionnaires will contain also questions presenting imaginary future possible scenarios to give the management of the coastal area the tools to predict the reactions to eventual interventions. The objectives of the eco-social Observatory of the OASIS project are:-To evaluate the Quality of Life level and the Social Capital of the community in relation with the eco-geo-bio-physical parameters of the ecosystem.-To define the sensitive social parameters to be considered.-To determine the degree of social pro-activity or reactivity of the community towards sensitive parameters.-To establish, using an expert system analysis, a forecasting capability of the effects on quality of life and social capital of the community for an integrated geographic management.-To set up a project of coalition building aimed to increase the people level of participation and the civic engagement."
