Study on the morphological transformation of urban fabric of Segunbagicha area with special focus on open spaces and its impact on livability

Abstract

Dhaka has a long historical background of urbanization. During the past decades, due to complex interrelated forces of urbanization the city has experienced a rapid and dramatic transformation in its urban fabric. These transformations brought significant change in the urban environments which are affecting the livable condition of Dhaka city. With the introduction of high-rise apartments in the low density residential areas, it suddenly transformed into high density areas. The serene environment of these residential areas is gradually disrupted by the invasion of commercial functions, more intensely observed specially near CBD. The resultant effect of these transformations further continued to affect the physical elements of urban fabric and brought changes in plot configuration, built form with an increased density and decrease in open space. Segunbagicha, one of the old residential areas of Dhaka city faces such transformation. This study focus on the functional and physical analysis of the process of morphological transformation that is reflected by the changing land use pattern, increasing accessibility, densification of built form and specially decrease in open space. The findings will show that the fundamental physical elements of urban fabric are continuously affected by the process of transformation and as a resultant effect the open spaces of the area are decreasing in an alarming rate. This phenomenon is affecting the natural environment and hampered the interaction of the residents with open spaces. Thus the physical and mental well -being of the residents is affected by the transformation and creates negative impact on livability of the area.
