Context : Cong, AIUDF set for big gains in river islands dominated by Bengali-speaking Muslims, and hit by floods, BJP rhetoric.
- Chars are riverine islands in the Brahmaputra formed through silt deposits. Life in the char is defined by the mighty river.
- The riverine areas (island) of the river Brahmaputra, locally known as “Char/ Chapori” cover about 3.60 lakhs hectares of land and population of approx. 24.90 lakhs (as per Socio Economic Survey 2002-03).
- Distinction should be made between island chars, which are surrounded by water year-round and attached chars, which are connected to the mainland under normal flow.
- The chars follow a peculiar pattern of migration. They are subjected to erosion on their upstream and deposition on the downstream, due to which they migrate downstream.
- This affects the geometry and location of the chars during floods almost every year.
