This study presents the current status of two work-in-progress experiments of citizen’s participation in the design and self-definition of the resilient city developed in the Open Urban Lab of eTOPIA art and technology centre and in the Harinera communitarian art centre in Zaragoza (Spain). Both pilot projects are part of a main framework of research about the potential role of Informatics and communication technologies, citizen science experiment, self-fabrication and maker's tools in the citizen's participation to the resilient city. The goal of the investigation is to define a method of co-create and bottom up environmental analysis for a self determination of a resilient urban productive landscape. Moving from a definition of City 4.0 the investigation will focus on is on citizen's role in the bottom up revolution from smart city to resilient city. Finally it will be presented how the use of open technologies and co-design techniques are going to be involved in two pilot projects: La Milla Productiva mapping of the Digital Mile Park for a resilient landscape design; and Guerrilla Energética an artistic, low tech actions to transform wasted urban areas by means of workshops of self-defined energy productive landscapes.
