SEiSMiC (Societal Engagement in Science, Mutual Learning in Cities) is a European Commission-funded project dealing with social innovation in an urban context. The objective of the project is to build up a network of urban stakeholders who share knowledge and learn from each other in the field of social innovation. These stakeholders include researchers, practitioners and city administrations as well as NGOs, grassroots movements and local citizens. The network is being developed simultaneously in 10 partner countries (Austria, Belgium, the Czech Republic, Germany, Hungary, Italy, the Netherlands, Sweden, Turkey and the United Kingdom). Network partners meet regularly for workshops at national, transnational and international level to discuss a variety of topics and to provide recommendations for research and policy making. SEiSMiC activities are strongly linked to the Joint Programming Initiative (JPI) Urban Europe, thus the recommendations derived from SEiSMiC are directly integrated into JPI Urban Europe's Strategic Research and Innovation Agenda.
