讲座题目：Systemic Change for Cities: Transition Pathways
In order to achieve our greenhouse gas reduction goals, we need to think about the urban form, density and the integration of green spaces. Solar collectors, sustainable water management and electric vehicles are all important, but much more can be achieved with better urban form. For cities to succeed in carbon reductions, a ‘science of cities’ is necessary that gives clear guidance and the evidence based required for decision making on future urban planning and development. There must be more focus on the optimisation of urban form, and transition pathways for existing cities to regenerate through smart land-use planning, infill development and new policies for zoning interventions. Most of the legal framework for cities is now over 15 years old, which means these policies have been formulated at a time without strong climate change impact awareness. How can we accelerate systemic change towards more resource-efficient, resilient and liveable cities? The increase of compactness to make cities more walkable is a way forward, combined with better access to green spaces and an increase in tree canopy cover.
Professor Steffen Lehmann, PhD AADip RIBA AoU, has been a driving research force in the field of sustainable cities for over 20 years. He is currently Professor of Sustainable Architecture and Director of the Cluster for Sustainable Cities, an interdisciplinary group of 40 researchers at the University of Portsmouth (UK). His seminal book ‘The Principles of Green Urbanism’ (2010) has introduced a new assessment framework for future cities and sustainable city development. In 2018-19, he is a Visiting Professor at the University of Nevada at Las Vegas, USA; and at Anant National University in Ahmedabad, India.
