The worldwide challenges of sustainable development are becoming progressively more complex and unpredictable. Meaningful individual, organisational, national and international responses to this complexity and uncertainty in turn require ever greater levels of innovation and sophistication. More than ever, world class research is central to providing the evidence base necessary to inform best practice in the sustainable planning, design and management of the 21st Century city. Sustainability leaders and change agents must not only be aware of what is happening at the leading edge, but how to apply it in their own circumstances. This capstone course in the Master of Sustainable Built Environment(Extension) program aims to provide this knowledge. It connects theory with practice and research with implementation to equip students with the advanced knowledge and skills needed to tackle the most demanding sustainability challenges, from local to global.
