Open Unknowns (1)

Unknown Does polycentric urban governance causally increase urban biodiversity and ecosystem service delivery relative to centralised or fragmented governance, and what governance design features (scale-matching, monitoring, sanctions, polycentrism) drive differences in urban green infrastructure outcomes? u-urban-biodiversity-governance-regime-causality

Active Hypotheses

Hypothesis Urban tree canopy cover exhibits a nonlinear threshold effect on heat island intensity: cooling effect is negligible below ~15% canopy cover, then increases rapidly between 15-30% (cooperative evapotranspiration), then plateaus above 40%, consistent with a percolation-like transition in connected canopy enabling coherent evapotranspiration across the urban landscape. medium
