This book addresses the role of social capital in promoting rural and local development. The recent financial and economic crises have exposed the European Union (EU) to an increased risk of social exclusion and poverty, which are now at the heart of its economic, employment and social agenda with explicit reference to rural and marginal areas (Europe 2020). The authors' work from the notion that rural development is not imposed from the 'outside', but depends also on endogenous factors, namely local cultural and ecological amenities, eco-system services, and economic links with urban areas which expand rural opportunities for innovation, competitiveness, employment and sustainable development. Social capital is of paramount importance because it helps build networks and trusting relations among local stakeholders in the public and private spheres, and supporting the enhancement of governance of natural resources in rural areas. --
