UCL formally launched its Grand Challenge of Sustainable Cities - a programme to rally the university's breadth of expertise in service of urban sustainability - at an evening event on 8 July 2009.

Hundreds of invited guests - including policymakers and practitioners from government bodies and non-governmental organisations, architectural practices and engineering firms - were welcomed by UCL President and Provost Professor Malcolm Grant.

Professor Grant said that by the end of the 21st century some 80% of humanity would live in cities. This rapid growth would further stress the urban environment, posing significant problems in areas such as food security, energy, water, waste, transport, economy, trade, manufacture, wealth creation and quality of life. This evening marked UCL's commitment to deploying the breadth of its expertise - in imaginative, interdisciplinary collaborations and partnerships with policymakers and practitioners - to make our cities fit for purpose. 

A panel discussion followed, moderated by Roger Harrabin, BBC Environmental Analyst, with presentations by: Professor Mark Maslin (UCL Geography), Director of the UCL Environment Institute; Professor Raquel Rolnik (University of São Paulo), United Nations Special Rapporteur on the Right to Adequate Housing; Yvonne Rydin (UCL Bartlett School of Planning), Professor of Planning, Environment & Public Policy; and Paul Finch, Programme Director of the World Architecture Festival and Editor Emeritus of 'Architectural Review'.Professor Maslin declared that the battle to deal with climate change will be won or lost in cities, which are responsible for 75% of energy demand. Cities are uniquely vulnerable to the effects of climate change - in particular to sea-level rises and heatwaves - yet the positive news is that mayors are able to act more nimbly and urgently than national governments. He welcomed the practical solutions emerging from the C40 group of leading cities.

Professor Rolnik said that, worldwide, the cities of today are mostly shaped by informal settlement. Real estate markets and territorial-exclusion machinery marginalise the poor, pushing them toward perilous, hazard-prone settlements, far from the healthcare, and educational, cultural and employment opportunities they need. Horizontal expansion of cities necessitate more travel, further degrading the environment. Most public-housing policies are mechanisms for containment of the poor.

Professor Rydin asserted that - with the right kinds of governance - cities can be the key to sustainable development. We should focus on those institutions that influence behaviour, rather than relying solely on technological intervention. Crucial factors would be the sharing of experience, and learning through experimentation, as part of transparent and accountable governance. 

Mr Finch described the many appealing aspects of urban life. He decried the trend for 'gling' (green bling) such as add-on wind turbines, and said that achieving the right combination of aesthetics, functionality and sustainability in our cities would require 'design intelligence'.  

Mr Harrabin then moderated a set of lively questions and comments from the audience. Contributions included: the volume and complexity of existing data, and the need to take informed action, but urgently; the need for audit and accounting mechanisms to place value on resources such as green spaces; urban agriculture as an aspect of meeting the projected doubling of demand for food; the tension between preservation of heritage and sustainable development; defeatism in the face of complex problems; buildings' durability, adaptability and planned obsolescence; new-build versus the need to retrofit existing property; that a sustainable city is not necessarily a radically different city; the need to start with an understanding of the impact of human behaviour; the need for common standards and languages in order to measure and predict; the danger of being too holistic - by taking everything into account, effectively nothing is addressed; the need to harvest the energies of populations, not just governments; carbon as a proxy for many other goods and services (eg water).UCL's new journal of sustainable cities, 'palette', was also launched at the event.

UCL Context

The Grand Challenges

UCL is London's global university, a research powerhouse working across the full spectrum of academic disciplines. The excellence, breadth and scale of our research, in combination with our location in London, provide us with both opportunities and obligations. Through our new UCL Research Strategy, we have committed ourselves to harnessing our collective expertise to maximise our impact on the world's major problems.

We focus on issues of global significance, which we call the Grand Challenges: initially Global Health, Sustainable Cities, Intercultural Interaction and Human Wellbeing. We can only address these Grand Challenges by transcending the boundaries between academic disciplines: by bringing together our diverse insights, creativity, perspectives and procedures. We are working to transform our individual expertise and analysis into collective wisdom - that is, knowledge applied judiciously in partnership with policymakers and practitioners.

The Grand Challenge of Sustainable Cities

Although the Grand Challenge of Sustainable Cities draws on our entire spectrum of expertise, three interdisciplinary centres form a platform for our efforts.

The UCL Energy Institute brings together different perspectives, understandings and procedures in energy research, transcending the boundaries between academic disciplines. It coordinates multidisciplinary teams from across the university, providing critical mass and capacity for ambitious projects. It has a particular focus on the area of energy-demand reduction, designed to speed the transition to a low-energy, low-carbon economy and to sustain human civilisation through the 21st century and beyond.

The UCL Environment Institute is the focal point for environmental research and related activities in UCL. Its aim is to improve communication between those who carry out the research and those who need its findings. This will lead to a better understanding of how the environment functions, how human activities impact on it and how environmental policies can be effectively implemented.

The UCL Urban Laboratory is a university-wide initiative to bring together the best urban teaching and research at UCL, across the arts and sciences ranging from civil engineering to film studies, from urban history to the latest developments in architectural design. Its initial three themes are: social cohesion, urban infrastructure and the public realm; cosmopolitanism and new forms of urban citizenship; and urban landscape and design in the post-industrial metropolis.
