  1. 1. GEO524 Seminar in Urban analysis and problems Himmet Haybat
  2. 2. <ul><li>Development </li></ul><ul><li>Development is a process of becoming and a potential state of being. </li></ul><ul><li>Sustainable Development </li></ul><ul><li>Development that meets the needs of the present without compromising the ability of future generations to meet their own needs . </li></ul><ul><li>In urban planning, sustainable development represents a reorientation of traditional goals. </li></ul>
  3. 3. <ul><li>A sustainable city enhances the economic, social, cultural and environmental well-being of current and future generations </li></ul><ul><li>Sustainable cities, sometimes known as ecological or ‘eco’ cities, are settlements designed to have as little impact on the environment as possible. </li></ul><ul><li>These can be pre-existing cities that feature management directed towards reducing the inputs of energy, water and food and reducing the outputs of heat, water and air pollution, or they can be cities designed from scratch with these concerns in mind. </li></ul>
  4. 4. <ul><li>A controlled population for whom adequate, meaningful employment is available </li></ul><ul><li>Adequate governance set-up which can meet the needs of the populace and ensures civic responsibilities, community participation, a sense of identity, transparency and equity in local institutions </li></ul><ul><li>Planned housing colonies with adequate infrastructure like schools, parks, drainage system, local Medicare establishments. </li></ul><ul><li>Efficient basic civic amenities for a reasonably comfortable existence </li></ul><ul><li>Effective environmental infrastructure to address the issues of untreated sewage and waste polluting rivers, lakes and coastal zones </li></ul>

  14. 14. <ul><li>C algary is a city in the Province of Alberta, Canada. It is located in the south of the province, in an area of foothills and prairie, approximately 80 km (50 mi) east of the front ranges of the Canadian Rockies. The city is located in the Grassland region of Alberta. </li></ul><ul><li>In 2006, the City of Calgary had a population of 988,193 making it the third-largest municipality in the country and largest in Alberta . The entire metropolitan area had a 2006 population of 1,079,310, making it the fifth-largest census metropolitan area (CMA) in Canada. In 2009, Calgary's metropolitan population was estimated at 1,230,248, raising its rank to fourth-largest CMA in Canada. </li></ul><ul><li>Located 294 kilometers (183 miles) south of Edmonton, Statistics Canada defines the narrowly populated area between these cities as the &quot;Calgary–Edmonton Corridor.&quot; </li></ul>
  15. 15. <ul><li>Economic activity in Calgary is mostly centered on the petroleum industry, agriculture, and tourism. In 1988, Calgary became the first Canadian city to host the Olympic Winter Games. </li></ul>Outline map of Calgary
  16. 16. Calgary, Canada
  17. 17. <ul><li>T he city is large in physical area, consisting of an inner city surrounded by communities of various density. Unlike most cities with a sizeable metropolitan area, most of Calgary's suburbs are incorporated into the city proper </li></ul><ul><li>Calgary maintains a major streets network and a freeway system. Much of the system is on a grid where roads are numbered with avenues running east–west and streets running north–south </li></ul><ul><li>Roads in predominantly residential areas as well as freeways and expressways do not generally conform to the grid and are usually not numbered as a result </li></ul>
  18. 18. <ul><li>However, it is a developer and city convention in Calgary that non-numbered streets within a new community have the same name prefix as the community itself so that streets can more easily be located within the city </li></ul><ul><li>Calgary Transit provides public transportation services throughout the city with buses and light rail. Calgary's rail system, known as the C-Train was one of the first such systems in North America </li></ul>

  33. 33. <ul><li>T he simplistic desire to develop where it's easiest and cheapest (e.g. flat, well-drained agricultural land). </li></ul><ul><li>R elative independence of municipalities makes competition fierce for industrial and commercial clients (i.e., in order to improve the city's tax base) </li></ul><ul><li>Historical inertia .(e.g., land platting makes cities monotonous and not ecologically-driven) </li></ul>
  34. 34. <ul><li>Planning problems are inherently wicked (e.g. difficult to define, have no rules that determine when they are solved, are not true or false but good or bad, are unique, basically political in nature and are often derivative of another problem) </li></ul><ul><li>Weak laws and regulations, and a related lack of enforcement. </li></ul><ul><li>Human greed (açgözlülük,hırs) </li></ul><ul><li>Ambition, Passion </li></ul>

  47. 47. <ul><li>Promotion of an economic base that has minimal environmental impact. </li></ul><ul><li>Why? Greater long run feasibility, less expensive to clean up, and maximizes the health of the environment. How? </li></ul><ul><li>P romote quaternary economic development (since wealth and educational attainment are related to the demand for a healthier environment ) </li></ul><ul><li>P romote businesses with low energy demands, and produce few or no toxins </li></ul><ul><li>P romote businesses with closed loop production process for durables in which manufacturers design products for disassembly and disposal or recovery or reuse </li></ul>

  55. 55. <ul><li>Sustainable economic development has become the world’s political objective to combat the intensified environmental problems and especially the non-reversible degradation of the natural environment </li></ul><ul><li>Sustainable development suggests a framework for the development of economic systems that respect the limits set by the natural environment </li></ul><ul><li>In this context, the examination of the pattern of sustainable development in the urban system becomes now all the more important </li></ul><ul><li>The intense presence of the humans in the urban system asks de facto (fiili, gerçekten yapılan) for a particular human-oriented interpretation of sustainability </li></ul>
  56. 56. <ul><li>Furthermore , urban systems require further specification of the general concept of sustainable development, one that will take into account the special natural and social features of the urban system </li></ul><ul><li>In addition , the fact that cities accumulate human population, they have to maintain certain levels of environmental quality, which are related to the healthy survival and reproduction of the human species </li></ul>
