In the EU-funded large scale project SI-DRIVE “Social Innovation: Driving Force of Social Change”, 25 project partners have mapped 1.005 cases in seven policy fields on all five continents. Results of the comparative analysis give insights into the highly diverse world of social innovation, the variety of actors and their interaction, and the systemic character of the concept. This comparative analysis is an explorative inventory of an empirically under-researched area. It includes social innovations in education and lifelong learning, employment, environment and climate change, energy supply, transport and mobility, health and social care, and poverty reduction and sustainable development. It shows that social innovation has become a ubiquitous concept. The key results of the mapping are available here.
