    • From literature review , it is found that,
    • Chittagong is growing at a rate of 4.5%, where more than 60% of the city dwellers are migrants from neighbouring districts, who are attracted to what is perceived as better living conditions and job opportunities in the urban area.
    • Massive pull of urban population due to economic growth.
    • Tremendous population pressure has far exceeded the infrastructure facilities, which is deteriorating the quality of urban or neighbourhood services.
    • The implication of such urbanization are manifested in day to day life.

  • 23. Part 03 Focus on research problem
  • 24. The Brundtland Commission , formally the World Commission on Environment and Development (WCED), known by the name of its Chair Gro Harlem Brundtland , was convened by the United Nations in 1983. The commission was created to address growing concern "about the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development ." In establishing the commission, the UN General Assembly recognized that environmental problems were global in nature and determined that it was in the common interest of all nations to establish policies for sustainable development .
  • 25. The most widely known definition of sustainable development comes from the Brundtland Commission, which defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." Rees, William E. and Roseland, Mark. 1991. Sustainable Communities: Planning for the 21st Century. "Sustainable community development is the ability to make development choices which respect the relationship between the three "E's"-economy, ecology, and equity: Economy - Economic activity should serve the common good, be self-renewing, and build local assets and self-reliance. Ecology - Human are part of nature, nature has limits, and communities are responsible for protecting and building natural assets. Equity - The opportunity for full participation in all activities, benefits, and decision-making of a society." Mountain Association for Community Economic Development (MACED): Hart Environmental Data Concept of sustainability P a r t 0 3
  • 26. Definitions of sustainability often refer to the "three pillars" of social , environmental and economic sustainability. A representation of sustainability showing how both economy and society are constrained by environmental limits. ^ a b Adams, W.M. (2006).

    • Historically, it is a port based market town where related trade and commerce have an induction on social life.
    • Pattern of economic growth is the guiding principle of urban growth and urban development.
    • It is the industrial development which brought a boom in urban growth.
    • Thus, being responsible as the guiding factor of urban growth, economy has received the focus of this research .

  • 31. Theoretical Premise P a r t 0 3
  • 32. According to Bill hillier, Designing cities depends on how we understand them. It is the understanding of cities as movement economies Proper design of cities gives way out in achieving sustainability. A glimpse from the theory by Bill Hillier “ Cities as Movement Economies” P a r t 0 3
  • 33. Activities that occur in economic, social, cultural and environmental processes. Cities as movement economies Cities could be understood from two sides Physical city Functional city Stocks of buildings connected by space and infrastructure Means Ends (Control) (Sustainability) P a r t 0 3

  • 39. Methodology Step 01: Literature study to gain the knowledge about the physical growth pattern of the city to know the evolving urban problems to develop the concept of sustainability to review the detailed area plan (DAP) of the city Step 02: Space Syntax Analysis of the city to understand the spatial morphology of Chittagong. Step 03: Examination of the prospects of detailed area plan (DAP) for sustainable urban development in the light of syntactic properties of the city. Step 04: Interviewing experts in critical issues.
