Although desert landscapes across the world reflect many similarities, the process of desertification is influenced by local factors. Elaborate with suitable examples.
Introduction
Desert lands capes are characterized by rainless, cloudless conditions, high insolation, high pressure and negligible water resources.

Main Body
Across the world, between 20-30° latitude, in western parts of the continents, tropical deserts are found.
Nevertheless, desertification also depends on several local climatic conditions.
Atacama falls on leeward side, also influenced by La Nina.
because:
(I) leeward side of Aravalli mountain
(ii) seasonal branches become moisture less, once they reach western Rajasthan.

Therefore, deserts are dynamic result of interplay of several conditions. Need to stop the expansion of deserts as a result of climate change.
Conclusion
Therefore, deserts are dynamic result of interplay of several conditions. Need to stop the expansion of deserts as a result of climate change.
