Contemporary media is saturated with images of extreme weather events, hunger, poverty, conflict, pollution, austerity, and financial crisis. Mounting evidence suggests the 21st century will be defined by unprecedented challenges related to environmental instability, economic inequality and risks to social well-being on a global scale. The idea of sustainability has become a focal point in efforts to tackle the root causes of these challenges yet often seems elusive. The meanings of sustainability and implications for action are as hotly contested as they are complex, wide-ranging and value-laden. As a result, this unit brings a wide range of perspectives to bear on questions of sustainability that integrate environmental, social and economic disciplines. The unit will develop your interdisciplinary understanding of sustainability through critical thinking, reflection and evidence-based argument focussed on practical case studies drawn from around the world. Unit delivery focuses on dialogue and inquiry between teachers, yourself, and your peers that respects the importance of diverse perspectives. The unit develops skills related to understanding core concepts, synthesising knowledge, communicating with diverse audiences, engaging in constructive debate and becoming more self-aware of what sustainability means and what practices it entails—professionally and personally.
