This volume focuses on concrete social innovations. The emphasis is on municipalities in both urban and rural areas, whether it concerns car sharing, addressing the various manifestations of demographic change, new forms of housing, or schools as centers of innovation. The volume aims to facilitate the understanding of social innovation processes, qualify behavior in such processes, and promote the discourse on the role of social sciences in, for, and during social innovation processes on the ground. It demonstrates how diverse the involvement of social sciences is with its theories and methods in practice, how it supports, enhances, and enriches social change processes; also, how it sharpens its theoretical understanding of social processes and its methodological creativity through them; and, finally, how social scientists themselves act as knowledgeable participants.
