Urban parks mitigate heat islands and pollution beyond borders via systemic green infrastructure networks

Marginalized communities, particularly in the Global South, are often excluded from green space planning despite bearing the brunt of urban heat and pollution. Informal settlements, which house over a billion people globally, are systematically denied access to parks due to land tenure insecurity and state neglect. Their exclusion reinforces colonial-era urban hierarchies and perpetuates environmental injustice.
The study’s focus on parks as isolated cooling islands reflects a fragmented urban planning paradigm that ignores historical injustices and Indigenous knowledge systems.
In reality, urban heat and pollution mitigation requires a systemic approach: green infrastructure networks must be designed as living corridors, not static amenities, with land tenure security for marginalized communities. The colonial legacy of redlining and privatization has created a patchwork of green spaces that serve the wealthy while leaving informal settlements to bake in concrete heat islands. True resilience lies in decolonizing urban design, centering Indigenous fire ecology and agroforestry, and treating green spaces as commons rather than commodities. The trickster’s lesson is clear: the systems we celebrate as solutions are often the ones perpetuating the problem, and only by inverting our assumptions can we build cities that cool rather than divide.
