This volume discusses a broad range of human welfare problems associated with and stemming from social issues, natural resource deficiencies, environmental hazards, vulnerability to climate change, and sustainability challenges. The chapters form a framework centered around the concept of social morphology, i.e. the role of humans in shaping society, and associated human-nature interactions which inform the ability to achieve sustainable welfare and well-being. The book is divided in six sections. Section I contains the introductory chapters where the book explores shifting interfaces between environment, society, and sustainability outcomes. Section II discusses contemporary issues of social welfare, and covers sustainable approaches in geo-heritage and ecotourism. Section III addresses the roots of various social conflicts and inequalities in relation to overpopulation, poverty, illiteracy, employment concerns, and human migration. Section IV highlights social security and areas of social deprivation, including urban affordability, gender equality, and women's health. Section V covers social issues resulting from natural hazards and disasters. Section VI concludes the book with a discussion of the way forward for social sustainability. The book will be of interest to students, researchers, policy makers, environmentalists, NGOs, and social scientists.
