Global City Systems & ICT
Global City Systems & ICT
• Developing GSS for Cities
• Evolution of intra-city systems
• Evolution of inter-city systems
Developing GSS for Cities• Improving inter-disciplinary communication
– Technologist / ICT / Social Scientist gaps• Barriers
– Emphasis on quantitative modeling – consider unstructured information analysis as bridge
– Emphasis on uniqueness – consider development of formal hierarchies of abstraction and scales
• Formal development of “urban science”– Development of next generation of planners administrators
• Shaping the futures of specific cities through collaborative narrative development
• Roles of ICT– Identifying quantitative and qualitative patterns– Understanding how cities work and how people live in cities– Understanding the futures of cities
Evolution of intra-city systems• Need for adaptability of cities in era of rapid change – lack of adaptability in traditional
design/planning methods• Transition from 19th Century industrial models of service & infrastructure management
to 21st Century decentralised management• Emergence of ICT as the fifth utility
– Open/closed, centralised/distributed• Making the invisible visible
– Knowledge aggregation and dissemination– Decentralised decision-making– Improving perceived Quality of Life
• Changing connectedness– Impacts of high-speed transportation and virtualization/dematerialisation on intra-city and
inter-city structures/systems– Maslow’s hierarchy / low -> Local connectedness, physical resources & infrastructure
dependencies– Maslow’s hierarchy / high –> Global connectedness, virtual resources & ICT dependencies
• Roles of ICT– New flexibilities, new dependencies– Governance of information– Impacts on democracy
Evolution of inter-city systems• National and global coupling among cities
– Decay of 19th Century “feeder network” model with hierachy of economic roles– End-point of current urbanisation – a small number of mega-cities?
• Forces driving urbanisation– Resource efficiency, economic opportunity, innovation– Abandonment of countryside– Specialised roles in global ecosystems
• Countervailing forces– Pollution– Need for diversity in skills and economies– Alternatives to GDP as key metric – Genuine Progress Indicator (M Porter), Better Life Index
(OECD)• Questions
– Can failing cities be brought back to life?– Minimal threshold of size for social & economic survival?– Is there a maximum or optimal size for a city?
• Role of ICT– Globalised ecosystems– Dematerialisation of work– Macro-economic modeling, policy decisions
