Sustainability policies shape the ways that society and the economy interact with the environment, natural resources and ecosystems, and address issues such as water, energy and food security, and climate change. These policies are complex and are, at times, obscured by contestation, uncertainty and sometimes ignorance. Ultimately, sustainability problems are social problems and they need to be addressed through social and policy change. Social Science and Sustainability draws on the wide-ranging experience of CSIRO’s social scientists in the sustainability policy domain. These researchers have extensive experience in addressing complex issues of society–nature relationships, usually in interdisciplinary collaboration with natural scientists. This book describes some of the evidence-based concepts, frameworks and methodologies they have developed, which may guide a transition to sustainability. Contributions range from exploring ways to enhance livelihoods and alleviate poverty, to examining Australians’ responses to climate change, to discussing sociological perspectives on sustainability and how to make policy relevant. Researchers, policy-makers and decision-makers around the globe will find this book a valuable and thought-provoking contribution to the sustainability literature. It is also suited to academics and students in postgraduate-level courses in social sciences and sustainability, or in courses in applied sociology, applied social psychology and other applied social sciences.
