Urban Decline/Urban Decay • Population decrease in areas of the city. • Suburbs become neglected: slums. • Push factors away from Sydney include: Land prices, air pollution, Traffic congestion, Overpopulation. • Areas become derelict (rundown) forcing people to move away from urban locations. • Economic restructuring: movement of business e.g Pyrmont wharves to Port Botany • Urban decline Pyrmont pre 1980s.
Urban Growth/Urban Sprawl • Suburbs move outwards causing urban sprawl - ¼ acre blocks. • Human environment (houses, roads) dominate physical environment (trees, bushland) • Increase in waste disposal, water consumption, traffic congestion • The population of Sydney is predicted to reach 4.9 million by 2026 • Increased spending of infrastructure. • Example: Western Suburbs Sydney
Management challenges, Waste, Resources, Infrastructure and Energy 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.
The need for Urban Consolidation and Ecological Sustainability. • Urban government policy initiative (renewal, consolidation) • Halting the process of urban sprawl by building medium-high density residential areas. • Rejuvenating old buildings, proving green space, improving public transport. • Urban renewal = Gentrification • Balance between human and physical environments: Ecological Sustainability
