Overview
Lower Dibang Valley is an administrative district in the north-eastern Indian state of Arunachal Pradesh. It lies in the eastern part of the state, in the foothills and lower reaches of the Dibang river, a major tributary of the Brahmaputra. The district headquarters is located at Roing. The district was formed by carving it out of the erstwhile Dibang Valley district, and is home to a predominantly tribal population, with the Idu Mishmi and Adi communities being prominent.

Geography
The district occupies the lower catchment of the Dibang river and its tributaries, where the river descends from the higher Mishmi Hills into the Assam plains. The terrain ranges from rugged forested hills in the north to gentler foothills and alluvial flats in the south, where the district borders Assam. To the north it adjoins Dibang Valley district, with Lohit and East Siang districts in its broader neighbourhood. The region is heavily forested, receives high monsoon rainfall, and supports rich biodiversity, including parts of the wider Mishmi Hills ecosystem.
History and administration
Lower Dibang Valley district was created when the earlier Dibang Valley district was divided to improve administration in a sparsely populated but geographically vast area. The lower portion, centred on Roing, became Lower Dibang Valley, while the upper portion, with headquarters at Anini, retained the name Dibang Valley.
The district is administered by a Deputy Commissioner under the state government of Arunachal Pradesh, with subordinate sub-divisions and circles handling revenue, development, and law-and-order functions. Local self-governance includes traditional village councils alongside the formal panchayati raj structure applicable in the state.
Demography and culture
The Idu Mishmi are the dominant indigenous community in and around Roing, while Adi sub-groups are present in parts of the district. Traditional festivals, customary law, weaving, and shamanistic practices remain important elements of community life. Reke (Reh), the principal festival of the Idu Mishmi, is widely observed in the district.
Economy
The economy is largely agrarian, with shifting cultivation (jhum) and settled agriculture producing rice, maize, millets, oranges, and vegetables. Forest produce, fisheries, small-scale horticulture, and government employment are also significant. Tourism, centred on natural and archaeological sites near Roing, contributes modestly to local livelihoods.
