ON/Osservatorio Nomade is an interdisciplinary research project initiated and promoted by Stalker, which proposes ways of interventions based on spacial practices of exploration, listening, and ralation, activated through creative tools of interaction with the environment and the inhabitants and with the archives of memories. Such practice aims to catalize the development of self-organized evolutive processes, through the establishment of social and environmental relations. The interventions build up a sensible, complex and dynamic mapping of territories and communities, through an interdisciplinary approach, activating interest and easly accessible. Such operative practice is a unique tool for knowledge sharing and contributes to the dissemination and widening of communities conciusness towards their territory and cultural environment, able to draw effective feedbacks through creative participation in territorial and urban management.
