Rann of Kutch - Salt Desert Northwest India

This image is from the Sentinel 2A satellite over Northwestern India. The region, known as the Rann of Kutch, is a salt marsh that is flooded during the monsoon season in summer and reverts to aridity in the winter months. The image is false color, presumably NIR, Red, and Green. As such, there is a distinct line between the vegetated grasslands, in red,  on the bottom half of the image and the salt deserts, in white,  on the top half of the image. Most notably the rectilinear pools of blue are the result of different minerals being extracted in the area. Considering that the whitest areas are arid and salty, the more blue there is in the image the more abundant other minerals in that area. The grasslands were formerly fed by the Indus river until its course was altered during an earthquake in the 20th century. As a product of human processes increased drought, overgrazing, and invasive species threaten the stability of the grasslands.
