The big issues facing cities are clear: Think globalisation, immigration, jobs, social exclusion and sustainability: Given that global urbanisation is taking place at an unprecedented speed with a scale, diversity, complexity and level of connectivity that challenges all existing perceptions, questions regarding the size, speed of growth, shape and land use of cities have become increasingly complex and politicised. Although cities themselves have a remarkable ability to innovate, there are broad disconnects between urban change and urban policy. The priority, therefore, must be to identify ways in which policy makers can create a regulatory environment that provides a framework for sustainable forms of urban development.
