Sustainability Notes

Economic Sustainability

• Requires high population density.
• Local businesses need regular customers.

Social Sustainability

• Share costs to save resources.
• Residents feel included and share an identity.
• Shared community spaces foster community.

Environmental Sustainability

• Ample protection for nature, wildlife, and humans.
• Pocket parks and roof gardens increase wildlife variety.
• Facilities support waste management and recycling.
• Adequate waste management is economical with high population density.
• Rainwater is used for cleaning; more trees provide shade and lower heat demand.

Sustainable Development

• Meets the needs of the present without compromising future generations.
• Regulates ecosystems, tangible resources (food, water), and flood regulation.
• Food can come from urban communities.
• Regulates local climate, water flows, and local air quality in urban ecosystems.
• Ecosystem services vary in size.

Ecosystem Services

• Provisioning: Tangible resources.
• Regulating: Climate and environmental control.
• Cultural: Intangible benefits like recreation.
• Supporting: Necessary for other services, e.g., soil formation, pollination, photosynthesis.
• Regulating includes providing shade.

Hazards

• Natural or man-made, leading to loss of life.

Fire Hazards

• Caused by unattended cooking or faulty appliances.
• Impacts: Burn injuries, smoke inhalation (headaches, dizziness), property damage.
• Property damage necessitates $$$ for repair/rebuild.

Air Pollution Hazards

• Contaminants in the air don't disperse properly.
• Sources: Industrial and motor emissions, increased car use.
• Impacts: Heart diseases, lung cancer, high exposure to nitrogen dioxide.

Traffic Hazards

• Speeding, red-light running, and drink-driving.
• Mitigation: Speed cameras and noticeable warnings.
• Impacts: Serious injuries, loss of life, disabilities.
