  3. 3. 3 Why Cities? – Poverty & Climate • Cities are the engine of growth to eradicate poverty and key to sustainable world to solve climate change. • Cities cover only 2 percent of land area of the world. However, they hold 50 percent of population and are responsible for up to 70 percent of greenhouse-gas emissions [and production]. (UN- HABITAT, 2011, Cities and Climate Change: Global Report on Human Settlements ) • "Cities are responsible for the majority of our harmful greenhouse gases. But they are also places where the greatest efficiencies can be made. This makes it imperative that we understand the form and content of urbanization so that we can reduce our footprint," said Joan Clos Executive Director of UN-HABITAT.

  6. 6. 6 Perspective from Outside 1961 Unemployment is estimated at as high as 25 percent of the labor force. Gross national product in 1960 was less than $2 billion and per capita income well under $100. Electric generating capacity is only one-sixth that of for example, Mexico and annual output is less than 70 kilowatt hours per capita. The only other source of energy is coal, there being no oil or natural gas. Mineral resources are deficient in several other vital categories. As much as three-fourths of the forest area is either denuded or covered with scrub growth. Exports have averaged a scant $20,000,000 annually as opposed to a volume of imports (exclusive of military items) amounting to $200,000,000 per year. Thus it can easily be seen that there is no possibility of an economic miracle being wrought in South Korea. Unemployment Rate 25%, Per Capita GNP well under U$ 100 Electric Generation Shortage No Oil, Gas, Mineral Resources Exports U$ 20M per year Imports U$ 200M per year Source: Foreign Affairs (October 1961)
  7. 7. 7May 20, 2014 A miracle that did happen  average GNP growth of 7.6% for 6 decades since 1950  Per-capita GDP $69 (1953) -> $20,000(2010)  transformed from a beneficiary to a prominent world player
  8. 8. 8 What are needed for Growth? • Y = f ( K, L, I | N ) • K(Capital): Finance, Capital Goods, Land, Buildings, Infrastructure, etc. • L(Labor): Labor, Expertise, Creativity, Entrepreneurship, Attitude, etc. • I(Institution): Organization, Regulation, Social Capital, Market, Equality, etc. • N(Natural Endowment): Natural Resources, Geographical Proximity, Climate, etc. • Black: can be borrowed • Red: should be built locally • Orange: can be borrowed in early phase, later should be built locally • Blue: little things to be done 8
  9. 9. 9 Where to Start? Cities & Infrastructure Resources Idea/Vision Will Action Resources are Limited, Idea is Unlimited 資源有限 創意無限 - Taejun Park (Slogan of POSCO) circa 1968 - Where to start? Building a STAGE where ideas can dance. Cities and Infrastructure
  10. 10. 10 Why Infrastructure? Path to Success Case of Gyeongbu Expressway • Started in February 1968, the construction of the four-lane highway with a total length of 428km was finished after 29 months in July 7, 1970. • The construction cost estimated 650 billion won at its highest. • The actual cost was 42.9 billion won (95.6% of fund was raised within Korea), making it the cheapest and also the quickest in the history of highway construction at that time. • The cost was equivalent to 23.6 % of the Korea’s annual budget.. • Expressway construction itself created more than 100,000 jobs. • Outcome: Transportation time & cost reduction (13.5T won worth). -> Business Boom (Supply-driven) • Issues: Opposition

Faced with limitations in land supply for urban development, the central government began to build several new towns in the Seoul Metropolitan Region including Bundang in Sungnam, Ilsan in Goyang, Pyeongchon in Anyang, Sanbon in Gunpo, and Jungdong in Bucheon.

  41. 41. 41 Lessons from Seoul and Korea • Today’s Rapid Urbanization in the world should be different from the past and west. • Growth with Compact City (e.g., Higher Density), Urban Infrastructure (e.g., Public Transportation), and Healthy Environment (e.g. Natural Area Preservation). • Timing and Speed are most critical. (e.g., Population of Seoul increased by 270,000 per year from 1960-1990) • Government Leadership is crucial.
  42. 42. 42 Integrated Total Solution of both Public and Private • Seoul is the only city which has recently overcome the extreme poverty and learned hands-on experiences in Sustainable Growth through transforming from one of poor cities to one of the high quality cities. • Seoul is ready to share its experiences with all the cities who want growth and sustainability.
