Water supply and irrigation

Infrastructure

Reduced rainfall, extreme rainfall events and increased temperature

• Reduced security of supply (depending on water source)
• Contamination of water supply

Wastewater

Infrastructure

Increased rainfall

• More intense rainfall (extreme events) will cause more inflow and infiltration into the wastewater network
• Wet weather overflow events will increase in frequency and volume
• Longer dry spells will increase the likelihood of blockages and related dry weather overflows

Stormwater

Reticulation
Stopbanks

Increased rainfall
Sea-level rise

• Increased frequency and/or volume of system flooding
• Increased peak flows in streams and related erosion
• Groundwater level changes
• Saltwater intrusion in coastal zones
• Changing flood plains and greater likelihood of damage to properties and infrastructure

Roading

Road network and associated infrastructure (power, telecommunications, drainage)

Extreme rainfall events, extreme winds, high temperatures

• Disruption due to flooding, landslides, fallen trees and lines
• Direct effects of wind exposure on heavy vehicles

Urban land-use planning/policy development

Management of development in the private sector
Expansion of urban areas
Infrastructure and communications planning

All

• Inappropriate location of urban expansion areas
• Inadequate or inappropriate infrastructure, costly retrofitting of systems

Land management

Rural land management

Changes in rainfall, wind, and temperature

• Enhanced erosion
• Changes in type/ distribution of pest species
• Increased fire risk
• Reduction in water availability for irrigation
• Changes in appropriate land use

Water management

Management of watercourses/lakes/ wetlands

Changes in rainfall and temperature

• More variation in water volumes possible
• Reduced water quality
• Sedimentation and weed growth
• Changes in type/ distribution of pest species

Coastal management

Infrastructure
Management of coastal development

Temperature changes leading to sea-level changes
Extreme storm events

• Coastal erosion and flooding
• Disruption in roading, communications
• Loss of private property and community assets
• Effects on water quality

Civil defence and emergency management

Emergency planning and response, and recovery operations

Extreme events

• Greater risks to public safety, and resources needed to manage flood, rural fire, landslip and storm events

Biosecurity

Pest management

Temperature and rainfall changes

• Changes in range of pest species

Open space and community facilities management

Planning and management of parks, playing fields and urban open spaces

Temperature and rainfall changes

• Changes/reduction in water availability
• Changes in biodiversity
• Changes in type/ distribution of pest species
• Groundwater changes
• Saltwater intrusion in coastal zones
• Need for more shelter in urban spaces

Transport

Management of public transport
Provision of footpaths, cycleways, etc

Changes in temperatures, wind and rainfall

• Changed maintenance needs for public transport (road, rail) infrastructure
• Disruption due to extreme events

Waste management

Transfer stations and landfills

Changes in rainfall and temperature

• Increased surface flooding risk
• Biosecurity changes
• Changes in ground water level and leaching

Energy

Transmission lines

Extreme wind, high temperatures

• Outages from damaged lines
