Issue
 Waste: Increased population –
more waste.
 Resources: Extra Demand for
water, food
 Infrastructure: traffic
congestion, demand for
hospitals and schools.
 Energy: power grid failure, fossil
fuel energies.
Management

More recycling schemes,
incentives to reduce packaging
 Water restrictions, food
regulations
 Public transport initiatives,
decentralisation of economy,
government funding.
 Green energy technologies,
reduction in over use of energy.
 Urban government policy

initiative (renewal,
consolidation)
Halting the process of urban
sprawl by building mediumhigh density residential areas.
Rejuvenating old buildings,
proving green space, improving
public transport.
Urban renewal = Gentrification

physical environments:
