Human Cities is shaped as a multidisciplinary European network composed of various profiles: universities, design centers and design weeks, ICT platforms, service design and creative design consultancies. Led by Cité du Design de Saint-Etienne [FR], the partners share their know how in innovating with people in the urban space using design as a creative and sustainable tool. The focus of Human Cities Network (2014-2018) will be to analyze, test and implement the process of engaging people in co-creating and “challenging the City scale and Flow space in Europe today”. People are the key to design change in a network society and to respond to the growth of ‘flow space’, which is both physical and digital. To go beyond planning practices on the urban territories, the partner cities are enhancing unplanned activities within a frame of 13 shared values: empathy, wellbeing, sustainability, intimacy and conviviality, mobility and accessibility, imagination and leisure, aesthetics, sensoriality, solidarity and respect. Those values applied to everyone follow an intergenerational equity. We are here on a subjective territory where ‘an alternative environment’ is sought. By rejecting 'specialities' and compartmentalised disciplines, this interdisciplinary and multicultural European partnership brings together designers, architects, urban planners, researchers, sociologists, philosophers, psychoanalysts, translators, artists, historians and art historians, bloggers... The State of the Art, which is enriched by Experimentation Labs, Users experiences and testing, Interaction and Exchange workshops in order to assess and implement sustainable results within the European urban territories, is coupled to Masterclasses and a ‘work in progress’ exhibition. Through applied research and co-creation, Human Cities Network appears as a continuous human-driven cultural programme questioning the position and status of people in relationship to their city and ever-changing flow space(s).
