Development is not a new phenomenon in the Chittagong Hill Tracts as from British period miniature interventions took place, but the region became a site of wide range of development activities after the liberation war. Erstwhile, indigenous people over this area were solely engaged in traditional way of living which kept them completely reliant on subsistence based economy. During that period; their livelihood utterly relied on shifting slash and burn cultivation which is traditionally called jum. Afterwards in colonial era and Pakistan period-introduction of private ownership, nationalization of land, introduction of reserved forest, commercial extraction of timber, increased linkage with low land, improved road networks and industrial use of resources has result in severe depletion of forest resources. Deforestation and land degradation had adversely affected the livelihood of the indigenous people in CHT, as most of them were solely depended on agriculture. After liberation, Bangladesh Government sponsored in-migration of people from some of the heavily populated plains districts during the late 1970s and early 1980s. About 250,000 in-migrants (Bengalis from neighboring plains districts) were encouraged to settle during this period and they were primarily located on land that was already occupied or claimed by the indigenous residents. According to AmenaMohsin, in a resource poor and agrarian country ownership of land is associated with the power structure of the community. In the CHT the indigenous people have been alienated from their land through a state sponsored project of settlement of Bengalis into the hill (Mohsin, 2000:66). Beside Bengali settlement programs state sponsored other initiatives like-afforestation programme, militarization and commercial use of land, intensified telecommunication, road construction, electrification, and overall infrastructural facilities put severe impact on the livelihood pattern of Indigenous people. Moreover, number of Bengali settlers got higher due to infrastructural advancement which in result promoted multiculturalism in this area. The rise of Bengali population in the CHT after liberation has dramatically changed the ratio of indigenous communities and Bengalis. According to Asian Indigenous people’s pact at the time of independence of India and Pakistan, the total population of CHT was only 247,053. Out of this number, only 2.5per cent were Bengali (including 1.5 percent of whom were Bengali Muslims). But after 20 years of the Pakistan period and 31 years of the Bangladesh period, the demography of CHT has significantly changed especially after the systematic illegal settlement of Bengali Muslims by the successive governments. (AIPP,2007). According to the provisional census report of 2001, the total population of the CHT was 1,342,740 (including ethnic Bengali and settlers). Of this number, 736,682 were Jumma (who are less than 0.5per cent of the population of the country) and 606,058 were Bengali.
