Book excerpt: "Satoyama" is a Japanese term describing mosaic landscapes of different ecosystems--secondary forests, farm lands, irrigation ponds and grasslands--along with human settlements managed to produce bundles of ecosystem services for human wellbeing. The concept of "satoyama," longstanding traditions associated with land management practices that allow sustainable use of natural resources, has been extended to cover marine and coastal ecosystems ( "satoumi"). These landscapes and seascapes have been rapidly changing, and the ecosystem services they provide are under threat from various social, economic, political, and technological factors. "Satoyama-Satoumi Ecosystems and Human Well-Being" presents the findings of the Japan Satoyama Satoumi Assessment (JSSA), a study of the interaction between humans and ecosystems in Japan. It was written by the 200-plus authors, stakeholders, and reviewers from Japan and elsewhere who make up the JSSA team. The study analyzes changes that have occurred in "satoyama-satoumi" ecosystems over the last 50 years and identifies plausible future scenarios for the year 2050, taking into account various drivers such as governmental and economic policy, climate change, technology, and sociobehavioral responses. This provides a new approach to land-use planning that addresses not only economic development but also cultural values and ecological integrity. This book is a key reference text for development planners, policymakers, scientists, postgraduate students, and others interested in the environment and development.
