The Forum will enable the controversial discussion about various ways to handle common goods in the public domain. Water will be used as an example to show the tension between communal administration and Solidarity Economy methods of public participation and self organization as well as to allow the exchange of practical experience. Can co-operatives provide an alternative to a democratic administration by public authorities? Is this possible despite the global trends of the commercialization of our common property and the attempts to turn it into an economic product by the politics of the EU, CETA, TTIP, TISA? At the end the project “Blue Community” will be briefly introduced posing the question: Are there other potential approaches to further activate the public's interest in their common property of water.
