Title : Global Distribution and Density of Constructed Impervious Surfaces
Journal : Sensors
Comment : They present the global inventory of the spatial distribution and density of
constructed impervious surface area (ISA). Examples of ISA include roads, parking lots,
buildings, driveways, sidewalks and other man-made surfaces.
They found that 1.05% of the United States land area is impervious surface (83,337 km2) and 0.43 % of the world’s land surface (579,703 km2) is constructed impervious surface.
China has more ISA than any other country (87,182 km2), but has only 67 m2 of ISA per person, compared to 297 m2 per person in the USA. The distribution of ISA in the world’s primary drainage basins indicates that watersheds damaged by ISA are primarily concentrated in the USA, Europe, Japan, China and India.
