This presentation focuses on eco-city development initiatives in developing countries towards developing low carbon society. Rapid urbanization in developing countries may be the most significant demographic transformation in our century as it restructures national economies and reshapes the lives of billions of people. At the same time, urbanization has also contributed to environmental and socioeconomic challenges, including climate change, pollution, congestion, and the rapid growth of slums. But as a major style of residential environment, city, has been endowed new contents by new ideas ever emerged in the history and eco-city development has emerged as a way to address climate change issues in the context of developing sustainable cities in developing countries. Eco-cities have the potential to address many of the problems like climate change and socio-economic aspects associated with urban development, as does the concept of sustainable development in an urban setting. Drawing on lessons learned from the planning and development process of several low-carbon eco-cities, this paper explores the potential of an integrated urbanism approach for developing countries. The objective is not only to mitigate factors contributing to climate change, but to manage risk, maximize resilience, and promote the successful economic and social growth of the urban eco community in developing countries. An integrated urbanism approach to planning may give us the tools to leapfrog the environmental and public health costs of economic progress and create a new model for cities across the developing world.

    • Presentation outlines
      Part 1
      • Urbanization Process & Climate Change Issues
      • Historical Development of City & Eco-City Concept
      Part 2
      • Case Study & Lessons Learned
      • Conclusions & Recommendations
    • Urban Interaction and Global Concerns
      More than half the world’s population(over 3.3 billion) resides in urban areas - 5 billion by 2030
      120 Megacities were in 2000, the number is projected to rise to more than 160 by 2015
      75% of global economic production takes place in cities
      • about 90% of global urban growth now takes place in developing countries
      • urban share of GDP already surpasses 60% in developing countries
      400,000 km2 of new urban built-up area will be constructed within next20 years equivalent that of total world’s area in 2000
      • entire built-up urban area in developing countries is projected to triple
      Urbanization has greatly contributed to environmental and socioeconomic challenges
      • climate change, pollution, congestion, and the rapid growth of slums
      • By 2050 there will be an energy shortfall of 14 terawatts across the planet
      CO2 and methane levels in the atmosphere are higher than at any time in the last 650,000 years
      • lead to continuous increase of global temperature
      The increase in global emissions has been largely driven by increased emission from large developing countries
      • China, India, Brazil and the other growing economies of the world.
    • Urbanization and Climate Change
      Cities are now on the front line of the management of change and are playing a leading role in the global development agenda
      Globally, cities account for about 70% of energy related GHGs emissions, which leads to climate change -global warming
      City-level actions needs to be a central part in GHG emissions reduction strategies
      BUT HOW TO ADDRESS THE ISSUES…….?
    • Way Forward-------------
    • Emerging Eco-City Concept
      One Point Linear Perspective:“The Ideal City“ in 1470 by Piero della Francesca
      "Moving into eco-cities does not mean people will sacrifice modern conveniences and go back to a primitive relationship with nature. It is a lifestyle that does little harm to the environment while meeting the human race's increasing demand for a better life." - Professor Wang Rusong, DG, Ecological Society of China. 
      Howards’s Garden City (1898) inspired by the Utopian novel ‘Looking Backward’
    • Eco-City: Planning Issues & New-Urbanism

    • Case Study 2: Sino-Singapore Tianjin, China
      Hope for Future….
      • Tianjin was originally an industrial base for chemical manufacturing in northern China and has long been suffering from chemical pollution.
      • Deserted saltpans, saline-alkaline non-arable land and polluted bodies of water made up a third of the area.
      • But now this land is full of greenery and offers a comfortable environment to work and live

    • Case Study 3: Dongtan, China
      Located on an estuary tidal flat at the east end of Chongming Island at the mouth of the Yangtze River, about an hour’s ferry ride from Shanghai
      Have the potential to tap renewable energy sources such as solar and wind
      The start-up area of 6.5 km2, housing 80,000 people.
      Targeted for completion in 2020, to have covered 30 km2 with a population of 500,000 by 2050.
      1st eco-city in China (2003) proclaimed world’s first purpose-built carbon neutral city (ADB, 2010)
      1st phase was scheduled to complete in 2010 before Shanghai World Expo
      However, it largely failed to materialize
      Problems and pitfalls
      Ill-designed in rural areas
      Questinable economic sustainability
      displaced farmers were not likely to be able to afford housing at the eco-city site, even with 20% of dwelling units designated as affordable housing
      Management problems
      confusion between design firm and state-owned developer
      Unplanned funding
      Political will and lack of citizen participation
    • Japan’s Eco-Model City Innitiatives
    • Japan’s Eco-Model City Innitiatives
    • Stockholm, Sweden
      Hammarby Model (1995)
    • Stockholm, Sweden
      Key Features
      City council aimed to be two times more sustainable than Swedish best practices (as of 1995) on a range of indicators:
      most notably, energy efficiency per square meter
      also water conservation, waste reduction and reuse, emissions reductions, reduced hazardous materials in construction, use of renewable energy sources, and integrated transportation solutions
      A project team was formed to integrate these efforts into a single directionled by a project manager and an environmental officer with key representatives from different city departments
      This model streamlines various systems of infrastructure and urban service delivery, and provides the foundation and blueprint for achieving many of the sustainability targets
      Initial Outcomes (World Bank 2010)
      30% reduction in non-renewable energy use
      41% reduction in water use
      29% reduction in global warming potential
      41% reduction in photochemical ozone creation production
      36% reduction in acidification potential
      33% reduction in radioactive waste
    • Lessons Learned for Developing Countries
      Many solutions are affordable even if budgets are limited
      many creative, practical, & cost-effective solutions simultaneously achieve greater benefits
      Success is achievable through existing proven technologies and new innovations
      depends less on new technologies and more on appropriate technologies
      Think globally, act locally approach
      city authorities should first look at the innovation taking place within own city boundaries
      Many solutions benefit the poor indirectly and directly
      fiscal gains in city expenditures & utility payments can free up money for social investment
      Leadership and continuity
      Strong leadership with technical backgrounds and political will
      Citizen ownership and eco-consciousness
      people’s active participation in city programs
      Local characteristics
      local situation, including its budget, capacity, social conditions in devising urban strategies
      Opportunities to Capitalize
      many opportunities created by rapid change and successful innovation

    • Achieving the Harmonies of Eco-City in Developing Countries
    • Conclusion and Recommendations
      Eco-city frameworkmay be a reference for developing sustainable cities in developing countries towards developing low carbon society
      Eco-cities have the potential to address many of the problems world facing today
      • Global warming, congestion, rapid urbanization, energy and water
      Current design and planning practices among cities may be a challenge
      • rooted in patterns established in the 19th century
      Design of an eco-city or sustainable city will depend on an operating set of values
      • Effective and well-coordinated urban planning and land use policies
      • Appropriate spatial layouts to provide strong and sustained long term development and compound the economic, social, and environmental returns
      Communities, NGOs and local public agencies need to operate synergistically and with the government and other stakeholders
      • Goals and priorities need to be defined and agreed upon at an early stage so that expectations can be met and to diminish a fuzzy, uncertain planning environment.
      Appropriate technologies and local innovations should be prioritized
