Dhubri Brahmaputra Char Island Agriculture Assam

Dhubri district in lower Assam contains the largest concentration of river char islands — temporary sandbars in the Brahmaputra — where over 500,000 people from Muslim Bengali-origin communities (the Char people) practice flood-recession agriculture on the unstable alluvial deposits that form and erode with each monsoon cycle. Char farming involves precise timing of monsoon recession to plant mustard, jute, and vegetables on the exposed silt in October-November, harvesting before the next flood. Char farmers have developed a sophisticated land reading practice identifying safe planting zones based on silt texture, colour depth, and previous flood marks. The chars are administratively excluded from revenue settlement and forest rights, leaving char farmers in legal limbo without land records, bank credit access, or flood relief entitlement. Dhubri's char ecology supports one of the highest rural population densities in India — over 1,000 persons per square kilometre on the most stable chars. The river's continuous course shift means chars appear, grow, merge with the bank, and disappear on decadal timescales, requiring constant adaptation of settlement and farming.
