It had 1) easy access 2) safe anchorage 3) position near the mouth of Meghna which was the principal route to the royal capital.

With in that, the master plan area was 259 sq. km and that master plan governed till the approval of the current one.

Land slide

Concern of experts and intellectuals 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.

Part 03Focus on research problem

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."

Concept of sustainability

P a r t 0 3

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.

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 .

Theoretical Premise

P a r t 0 3

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

Activities that occur in economic, social, cultural and environmental processes.

Cities as movement economies Cities could be understood from two sides
