Based on more than thirty case studies in eight different countries, this book explores the governance dynamics of local social innovations in the field of poverty reduction. The diverse team of contributors reflect on the trajectory of social innovation in European governance. They illustrate how different governance dynamics and welfare mixes enable or hinder poverty reduction strategies and analyze how they involve a diversity of actors, instruments, and resources at different spatial scales. The contributions are based on research motivated by the standstill in the fight against poverty in Europe and the anxiety that conventional macro-social policies are insufficient to deal with the current challenges.
