Can some one please elaborate that how the pattern of urban growth can be significant for the identification of new sites pertaining to future urban development of a mega city?
Dear Jibran,
Among other things, the pattern or urban growth can help urban planners understand the demand for land. They can then add transportation (and other) infrastructure in that direction anticipating growth leading to planned cities.
Melissa Schrock in her thesis The Potential Use of Land Readjustment as an Urban Redevelopment Strategy in the United States: Assessing Net Economic Value writes: "Since the 1968 passage of the New City Planning Law, the Japanese have practiced a land management system called senbiki – which literally translated means “drawing the line between town and country.” This system establishes two principal zones: Urbanization Promotion Areas (UPA), where development is encouraged, and Urbanization Control Areas (UCA), where it is, in theory, prohibited (Sorenson, 2007). Essentially, senbiki is an urban growth boundary and its primary purpose is to prevent sprawl. It also has a secondary effect, which is the disparity of land values between the two zones."
This I think this is a good way of stopping/understanding sprawl or conurbation or metropolization or loosing the intermediate land between urban and rural (ie in our countries in Latin America).
Cities must grow under planning systems; assuring infrastructure and puublic services.
Assure a proper urban design and housing with urban life...the shop on the first floor...mixed uses...etc.
Jibran, The pattern of urban growth may be a result of a number of written and unwritten rules, according to which people act (-> agent-based simulations). Since the observable pattern is a result (effect), it may be relevant to identify the driving rules (causes). After you've identified these rules, as an urban planner, you may want to think about working either according to these rules, or trying to influence them. According to your choice, you may allocate new sites at different places, or you may let other actors choose new sites (e.g., real-estate developers). Growth is not linear, rules are changing, and, thus, in less regulated and controlled environments, new sites may develop according to changing rules by actors different from urban planners as well.
Dear Ximena Samper and Christian Walloth, Thank you for your help. Much appreciated.
jibran, the pattern of urban growth or direction of growth are consequence of decisions made by the households and firms subject to physical, economic, social and policy aspects.
Spatial patterns of urban growth can be analyzed for scaling laws, looking into allometry and fractals as indicators. Such an approach may serve as an estimation of the rate of growth (e.g. allometry and differential rates) as well as a snapshot of existing spatial hierarchies (e.g. fractal structure). Depending on the goal of the policy-distributive efficiency or optimization of existing urban clusters, these approaches help shed light on the prioritization needed in resource allocation.
