Korangi, or Korangi Town, is part of the Karachi metropolitan area of coastal Pakistan. This photograph taken by an astronaut from the International Space Station highlights the contrast between the highly urbanised and industrialised Korangi area and the dense green mangrove forests and waterways of the Indus River Delta to the south. Away from the river delta, vegetation cover disappears rapidly to the northeast.
To the north and west, Korangi Town is bordered by the Malir, one of two rivers that pass through the Karachi metropolitan area (the other is the Lyari, not shown). The river course of the Malir is marked by green riparian vegetation, which stands out vividly against the surrounding grey to tan urban areas.
One of the largest industrial areas in Pakistan is located in Korangi. Known as the Korangi Industrial Area, or KIA, this region is marked by large buildings and lots, many having white-roofed structures. A conspicuously dark region marks the location of steel works; while bare soil and built materials are present, significant vegetation cover also contributes to the dark hues. In addition to steel, the KIA also includes textile, pharmaceutical, automobile, chemical, and flour industry facilities.
