independent of global climate change. Huang et al.  project that urban land areas will expand by 0.6-1.3 million km2 between 2015 and 2050, an increase of 78-171% over the urban footprint in 2015. Specifically in relation to floods and droughts, Güneralp et al.  calculate that even without accounting for climate change, the extent of urban areas exposed to flood hazards will increase 2.7 times between 2000 and 2030, the extent exposed to drought hazards will approximately double during this period, and urban land exposed to both floods and droughts will increase more than 2.5 times.
