In socio-environmental impact assessment studies, the first step is to know the context where the scheme is going to be implemented. For that aim, it would be very useful to set an indicator system to define the different dimensions of the context: demography, phisycal geography, social aspects, economic structure, political characteristics... Lot of literature touch those dimensions, but separately one of each other. Adding those cited system, the final result is a quite long and complex indicator system. Suggestions about integrated context indicator system will be very wellcome. Thanks.
