Future City Mega Issues
Environment
The environment will save itself
Environment: Greenhouse
Global temperature risen by ~ 0.9 degrees since industrial revolution
Why this matters?
More extreme storms
More droughts
More heatwaves
Wind & flood damage
Damage to vegetation, city
amenity, public health
More blackouts and deaths amongst
vulnerable

It’s Local Government that wears the cost of
climate change adaptation.
Too hot….
Four Degree Increase in 86 Years- as tracking with Australia’s 5% target- from 9 to 21 days of over 35 degrees (avge)- 50% less rainfall. - Sea level up 1.1 metres -- Zero snow cover - Rapid species loss-- Refugees up 250m - ‘Harvesting’ of frail - Riots- Blackouts and high energy costs
– Loss of business revenue City of Melb $9m day-And more…
Urban Heat Island – up to 7 degree difference

Environment: Greenhouse
Past 5 yrs Reduced by 31% 16 to 11 tonnes greenhouse pa
Saving over $400K pa in energy costs
1.26m tonnes emitted collectively by MV
community.7.3 tonnes per capita
Council emissions
Communityemissions
It appears we’ve peaked in MV
Very rare – due to little industry
World’s largest per capita emitter .(28t per person)15th largest total emitter in world
Australia total538m tonnes pa (103% of 1990)National

However on track for 4 degrees climate change
To keep it to 2 degrees will stunt GDP growth by 1-5% by 2050 (however our global incomes will have doubled by then)
Flooding and waterway damage…
City design to adapt
Environment: Water
Reduced by 53% since 2001
(374 ML in 01/02 to 175 ML 11/12)
Reduced stormwater
pollutants by 10% (rain gardens &
wetlands)
Reduced by 35% since 2001
(13,327 ML in 01/02 to 8625 ML 11/12)
Council water use
CommunityWater use
Source 63 ML from stormwater. (Up to 7000 ML
available)
12 year millenial drought was “the driest multi-year period on record, ..also by far the hottest” (BOM)
Lost…
Efficient Appliances - save A$3.2 billion (A$2.7b by households).Saved 13.5m tonnes of greenhouse gases.
Shade Tree– if none, $8000+ less value
Food– throw out $2000yr of edible food
Pobblebonk mating call: from 800m to only 14m…
1 to 2 species extinct each year. Over 35% threatened.
We only know of 1.5m out of 5m species.Habitat destruction vast – land use vital
Colony collapse disorder: impacting food security and species
Brown butterfly emerging 10 days earlier due to higher temps
Species extinction

Air pollution
Still so unknown and unregulated
- outdoor air pollution is carcinogenic to humans
- 2 million premature deaths worldwide
-pesticides, dry cleaning, diesel, fire retardants, coolant, etc
- plastics
-autism, developmental delays, cancer, heart attacks, asthma
Trees help418 street trees in Flemington - remove 177kg of air pollution
- hold 421 tonnes of carbon- slow down 122m3 of stormwater

Environment: Waste
2012- Moonee Valley households generated 43,000 tonnes of waste
The restRecycle (Yellow) & Garden
(Green) bins (23,000 tonnes)46% is diverted from landfill due to recycling
2003/04 just 15% diverted
-Landfill levies-Revenue from selling
recyclables

Emerging Economy
New types of jobs and businessneeding different land uses, built form, infrastructure, communication and design
Service PlansShould they also address these gaps?
1. Climate Change – more extreme storms, more heat waves, more extended droughts
2. Emerging economy and services- different jobs and industries and supporting needs
3. Emergency Impacts – more pandemics, flooding, riots
4. Technology advancements - ‘virtual care’, driverless cars, adaptable homes, crowd-sourcing data
5. Contamination- Land contamination and air pollution – identification and clean up
6. Community activism – seeking more knowledge, input, transparency, and urban action
