Testing the Drought and Heat Risk (DHR) Assessment Framework for Urban Green Infrastructure: Risk analysis geodata indicators

Risk analysis indicators

The following data set presents vulnerability and normalized risk indicators for the drought and heat risk assessment for urban green infrastructure and their ecosystem services as part of a doctoral dissertation. The data sources are provided by Shehayeb (2024). The georeference used is ETRS89 / UTM zone 33N (EPSG: 25832). The following indicators are ENVI-met outputs: Air temperature, Tv-Ta, UTCI (see R script), CO2 flux (Net CO2 Assimilation), and shaded area. With these indicators, both, drought and heat hazards were included.

For indicators: Water protection zone, air quality correlation, soil texture, shaded area, access to water, and access to space: Risk = Avg (Σ Vulnerability*Hazard)

a.      Shaded area: only the heat hazard considered

b.      Water protection zone: only drought hazard considered

c.      Rest: drought and heat considered

For normalizing indicators, the following formula is used: NewValue = (((OldValue - OldMin) * (NewMax - NewMin)) / (OldMax - OldMin)) + NewMin
