Urban sprawl and urban green spaces

Urban sprawl is a settlement pattern characterised by low-density development around cities, and is therefore associated with large land requirements and the destruction of natural habitats and their biodiversity. In response, policymakers have introduced regulations to curb urban sprawl and promote urban densification. However, increasing urban density is accompanied by a decrease in urban green spaces, which undermines the ability of ecosystems to cool the urban climate and positively influence the well-being of citizens. Furthermore, the loss of green infrastructure, particularly in low-income neighbourhoods, raises issues of environmental justice.

Urban sprawl and urban green spaces

Urban sprawl is a settlement pattern characterised by low-density development around cities, and is therefore associated with large land requirements and the destruction of natural habitats and their biodiversity. In response, policymakers have introduced regulations to curb urban sprawl and promote urban densification. However, increasing urban density is accompanied by a decrease in urban green spaces, which undermines the ability of ecosystems to cool the urban climate and positively influence the well-being of citizens. Furthermore, the loss of green infrastructure, particularly in low-income neighbourhoods, raises issues of environmental justice.

A study in Sydney found a negative relationship between tree cover and urban density. As housing density increased, tree cover decreased. It also found that green space increased with socio-economic status.
