Technology can be used to measure the extent of desertification

Recommended Posts

Desertification is a type of degradation of land in which the land becomes more arid. Desertification is a direct result of global warming, and approximately 12 million hectares of productive land becomes barren due to desertification annually. Remote sensing technology can be used to measure the extent of desertification. Could you ever thought that in order to fix that stuff scientists start to use satellite technology which helps scientists observe the land?
