Urban Heat Island
Social Space Access Barriers
Green roofs and walls
Limited size may not sustain vegetation health
Requires stakeholder consensus
Secondary benefit of limiting rain water runoff
Diffuses implementation responsibility and risk
Creates spatially accessibly social spaces
Able to reach multiple neighbourhoods
Cooling effect limited spatially
Releases ambient heat at night
Does not support inclusive social spaces
Cooling effect/heat sink
Improves vegetation health
Improves water table levels
Large Public Park
Spatially distant from vulnerable neighbourhoods
Cooling effects spatially limited
Limited social access
Size ensures sustainability of ecosystem
Room for flexible social spaces
Easy to implement
Why are vulnerable populations disproportionately impacted?
Lack of political representation
High costs of cooling systems
Why are existing urban social systems/structures not mitigating the impacts?
Lack of "problem" visibility
Reduced access to social and green spaces
Why are cities warmer than their surroundings?
What are the environmental determinants?
Concrete and Asphalt absorb heat
Impermeable Concrete reduces water tables
Water runoff leaches chemicals into water supply
Reduced Water tables negatively impacts vegetation health
Why are existing urban ecosystems not mitigating the effects?
Climate Change related extreme weather
Why is the impact of increased temperatures not felt uniformly across the urban environment?
Social Space access
Uneven distribution of green space
