UPSC Prelims 2022 Question:

Which one of the following lakes of West Africa has become dry and turned into desert?

Explanation:

• Lake Faguibine in northern Mali is dry and has been since the 1970s.
  
  
• The Lake Faguibine System, four interlinked lakes 80 km west of Timbuktu, was historically one of Mali's most fertile areas. But over seven years, droughts in the 1970s dried up the lakes.
  
  
• Then sand filled the channels connecting the lakes to the River Niger, with the result that when rain finally returned the water could no longer reach the lakes. The region's prosperity evaporated along with the water.
  
  

Therefore, option (2) is the correct answer.
