Patterns of spatial change from 1990 onwards spatial change driven by individual choices in weak planning environment
big RELATIVE change + big SPEED of the change easy to prove by empirical (quantitative) research – demographic statistics, census, planning permissions

Impact of the changes
increased life expectation
demographic change • delayed marriages and births
• low birth rates
ageing population population decline
migration• from outside EU • inside EU from outside CZ• inside CZ
increased spatial disparities
varied prosperity • metropolitan area of Prague • prosperous regional centres • rural country • old industrial parts
Issues, challenges and their management
newly emerged ISSUES
• control and safety • released control
increased unsafety • personal • property privatisation of
safety control • real emergence X
perception of crime risk
• climate hazards • floods
• accessibility • services• jobs
upcoming CHALLENGES
• ageing population • decreasing social
cohesion • peak oil?
ARENA FOR MANAGEMENT OF THE CHANGES
• poorly pronounced public interest
• national strategies & frameworks follow EU guidance
• weak role of regional governance
local decisions under control of local power groups and developers
• development-oriented public opinion
• civic groups treated as problem-makers X NIMBY
DIVERSIFIED IMPACT on particular
• regions• cities • neighbourhoods
• SOCIAL
GROUPS
WINNERS X LOSERS
WHICH GAME? • win – win? • zero sum? • lose – lose?
Recommendations
governance • new supra-municipal tier of
governance management of urban
sprawl / suburbanization co-ordinated development /
provision of services and facilities
co-ordinated development of transportation infrastructure
planning • top-down
o inward-oriented development policy
o internalisation of service costs
o enforcement of standards for new residential design
– passable neighbourhoods – small-grained
homogeneous units – compact cities – small-distance cities
• „soft“o campaign for better
awareness of long-term impact of social fragmentation
– Sustainable Cities
