This volume discusses the seminal interface between social entrepreneurship and sustainable development along with their inter-linkages. It traces the role of social entrepreneurship and innovations in societal transformation in creating sustainable societies, especially in developing nations. It explores how social entrepreneurship and enterprise is integral to the promise of fostering opportunities for socially disadvantaged groups (including the poor, women, and young people), as well as in addressing environmental and ecological issues apart from wealth creation. The book presents key concepts, case studies, and multiple innovative models involving social entrepreneurship, such as green financing, serial social entrepreneurship, sustainable livelihood creation, and well-being, in addition to highlighting global sustainable development goals of the United Nations. The chapters are organised under the broad themes of sustainability of the organisation, sustainability of the community, sustainability of the development, and sustainability of the community-organisation interface. They examine social change, social innovation, social enterprise, small and micro-enterprises, microfinance institutions, inclusive growth, education, productivity, physical health, waste management, energy retention, self-reliance, and corporate social responsibility. They contain emerging research issues in the field as well as critical assessments while bringing together theoretical and practitioners' perspectives. This book will be useful to scholars and researchers of development studies, social entrepreneurship, sustainable development, environmental studies, public policy, and political sociology. It will also greatly interest professionals from non-profit, corporate, and public sectors, other development practitioners, and international bodies.
