The Thar Desert of Sindh is divided into Nara, Achro, and Thar, all situated in the southern part of Sindh. [3] Historical records indicate that the normal monsoon is around 127.5 mm, but it reached a maximum of 443.9 mm in 2011 due to sudden climatic changes. Water scarcity is prevalent in many areas, leading to limitations in agriculture.
