Social Innovation in Sustainable Urban Development

According to Schumpeter [7,8], from whom our modern understanding of innovation derives, an invention must have proven itself in practice and in the market in order to be considered an innovation. [...]the initial question in the call for papers for this Special Issue was: [...]protagonists of social innovation emphasize that social innovation is, first and foremost, pro-social innovation and adds value for the community. [...]we can consider the potential tension between technological and social innovation as another dimension of international sustainability policy—besides the global vs. local and North vs. In my call for papers, I raised five specific questions to which the submitted papers made valuable contributions: (1) New, successful models of urban governance for city administration and sustainable urban development (SUD): Indeed, such examples of new governance models for SUDs can be found, but they are usually earmarked, such as for wastewater management in Milan [18] or urban rehabilitation through targeted support for coworking among the creative industries in Lisbon [19]. Alterman and Pellach [21] provide a global overview of legal options to ensure access to water, and show impressive evidence of how formal innovations are transferable.
