Augustenborg district of Malmö, Sweden, using nature to manage stormwater runoff has resulted in capturing an estimated 90% of runoff from impervious surfaces and reduced the total annual runoff volume from the district by about 20% compared with the conventional system . Urban greening is associated with lower ambient air temperature and relatively higher thermal comfort during warm periods . The scale and relative degree of management or integration of approaches drawing on nature with 'engineered' solutions affect their vulnerability to climate change. Small-scale urban NbS are relatively less vulnerable due to increased capacity for intervention, while the relatively greater contact between stakeholders and urban NbS  provides greater opportunity for human intervention to ensure the survival of urban vegetation during droughts or heatwaves.
