The largest metropolis in Bangladesh, Dhaka is home to a large number of facilities and a large number of people that travel here daily for employment. These people reside in impromptu colonies or slums and are primarily from rural areas. Rural poverty and natural catastrophes are driving the present situation of urban migration, moveable people on the streets start living on the roadside, on the Rail track and bus stop, and in any other purchasable locations including empty buildings. Numerous unauthorized constructions have been established as a result of the large underprivileged population. Rural poverty and natural catastrophes are driving the present situation of urban migration, forcing people to shift to Dhaka in pursuit of employment. These moveable people on the streets start living on the roadside, on the Rail track and bus stop, and in any other purchasable locations including empty buildings. Numerous unauthorized constructions have been established as a result of the large underprivileged population. Aside from that, multiple political stakeholders have established several different illegal constructions throughout the city. These illegal settlements are demolished by authorities' force evictions, which is a regular phenomenon in Bangladesh. This study aims to assess the future management of demolishing irregular settlements in Dhaka and the effects of dismantling unauthorized colonies. By far, this study adds the criteria that are crucial in determining the impact of tearing down multiple illegal structures on government land in Dhaka. This study will be a contribution to the field of research, enabling academics to educate about the challenges posed by unauthorized immigrants in slums in developing countries and prospective management strategies for the expulsion of illegal settlements.
