3. Population Growth, Cities & Urban Growth

4. POPULATION GROWTH Exponential growth rate over the past 200 years Up to 1800 - 1B Up to 1900 - 1.7B Up to 2000 - 6+B  0.7B increase 1800-1900  4.3B increase 1900-2000 URBANIZATION  CONCENTRATION IN CITIES Approximately half of the 6B people lived in cities in 2000 Projections indicate that 49.3% of the total world population will live in urban centers of all Developing countries by 2015 Cities, Population & World Trends: The Less Developed and Developing Nations

5. , Cities, Population & World Trends: The Less Developed and Developing Nations URBANIZATION RATES 1900 - less than.3B 2000 - around 3B (UNCHS, 2001b) URBANIZATION RATES ARE UNEVENLY DISTRIBUTED Industrialized nations: decline to from 1.1%  0.6% between 1995 and 2015, Least Developed nations: as much as 4.6% annual urbanization rates projected to 2015

6. Cities, Population & World Trends: The Less Developed and Developing Nations (continued) GLOBALIZATION : A new trend evolving from the economic sector Inevitable outcomes social exclusion - increase the “probability of land speculation, and therefore, of increased land prices” (UNCHS, 2001a). Human development - such trend, without institutional interventions, most likely will increase difficulties for the urban poor in less developed and developing nations Protect and repair the environment - is precisely in these countries were squatter communities are now home from 30 to 60 percent of their urban populations

7. Planning in the Third World - 1950’s –1st and 2nd worlds –3rd world - everything else 75% of the human race UN HABITAT - 2000 –Developed –Developing –Less Developed Future challenges – Poverty and … –Housing is the major concern –Food –Transportation –Water –Energy –Environment - Air –Education Evolution of Views about Planning in the World

8. Urban Form Classical Theories of urban form (at city level) Concentric Growth Theory (E. Burgess, 1925): tries to explain the patterns of sociological phenomena in Chicago, and how a city with a main CBD expands through rings of residential growth in all directions from it; Concentric Growth Theory (E. Burgess, 1925): tries to explain the patterns of sociological phenomena in Chicago, and how a city with a main CBD expands through rings of residential growth in all directions from it; Multi-sector Theory (H. Hoyt, 1939): extended the concentric theory and explains how similar types of land use are developed along transportation axes; Multi-sector Theory (H. Hoyt, 1939): extended the concentric theory and explains how similar types of land use are developed along transportation axes; Multiple nuclei Theory (Harris and Ullman, 1945): growth takes place around different urban centers (historic or contemporary) approximating a constellation pattern of development.

Public transportation +/- 39% of operating cost of public transportation is paid by fares 60% of cost is paid by Governments Private (Car) Paid mostly by owners (purchase, fuel, maintenance, insurance, parking etc.) Public roads and highways are paid by a variety of taxes Charges on licenses, registration, gas taxes, Highway Trust Fund Highway Trust Fund Funding for Federal highways construction ECONOMICS of TRANSPORTATION Source: Contemporary Urban Planning J.
