The ‘Sahel’ region of the Sahara desert is associated with the southern moving edge of the Sahara desert.
– The Sahel is a transitional zone in Africa located between the Sahara desert to the north and the Sudanian Savanna to the south.
– It stretches across the continent from the Atlantic Ocean to the Red Sea.
– The name ‘Sahel’ comes from the Arabic word ساحل (sāḥil), meaning ‘coast’ or ‘shore’, referring to the region as the southern ‘shore’ or edge of the vast Sahara desert.
– The Sahel experiences a semi-arid climate and is ecologically fragile, facing challenges like desertification, which involves the southward expansion of the Sahara into the Sahel region, hence it can be described as the ‘southern moving edge’.
