Title: Can Hong Kong be developed into a sustainable city
1Unit 5 Can Hong Kong be developed into a
sustainable city?
2I. What is a sustainable city?
1. What is a sustainable city?
A sustainable city is a city which follows the
principle of sustainable development in resource
allocation and planning for the future
3- Sustainable development
- Development that meets the needs of the present
without compromising the ability of future
generations to meet their own needs
4If a city is to be sustainable, plans for its
development must consider equally the economic,
environmental, social needs of the society
5We must also respect our natural environment so
that exploitation of natural resources in the
process of economic growth does not exceed the
carrying capacity of our earth
62. What are the characteristics of a sustainable
city?
The key characteristics of a sustainable city are
that it is able to balance economic, social and
environmental demands in the process of urban
development
7The city can be sustainable in every aspect of
life
Natural environment
Textbook P. 170
- To protect air, water and other natural resources
- To conserve the habitat of fauna and flora
8Energy consumption
- Use of renewable energy such as solar and wind
energy - Strong energy conservation and management
strategies
9Transport system
- Use of pollution-free and environmentally
friendly transport such as railway - Pedestrianisation of urban areas
10Resource management
- Efficient and effective use of resources
11Urban development
- Level of development within the carrying capacity
of a place - Strike a balance between urban development and
environmental conservation
12- Achieve a competitive and prosperous market-based
economy
Economy
13Social equity
- Respect for inter-generation and intra-generation
interests - Achieve equality of opportunity in the society
14Decision-making process
- Adequate public participation in making decisions
about the future development of a city
153. How can we measure the level of sustainable
development of a city?
- Economic, environmental and social indicators can
be used to measure the performance of sustainable
development of a city
- These indicators can help us to manage problems
of development, and enable citizens to evaluate
how successfully the society is moving towards
higher levels of sustainability
16 Refer to the maps and answer the following
questions.
17 1. Compare and describe the changes of
coastline, reclaimed land area and the size of
Victoria Harbour in 1969 and 2003.
182. What are the causes of these
changes? ______________________________________

As Hong Kong becomes more urbanised, there is an
increasing demand for land to accommodate
different types of development, particularly for
commercial land in the CBD. Since there is a lack
of flatland around Victoria Harbour and Central
District, reclamation is one solution that serves
this demand.
193. What problems do you expect if this trend
continues? __________________________________

- Victoria Harbour will shrink further in size.
- Harbour currents will become rougher and
- passages more dangerous.
- We will lose the beautiful scenery of the
harbour - and the tourism industry will be affected.
- Water pollution will become more serious as the
- water flow in this area will slow and pollutants
- will be more persistent because of less active
- drainage.
20Below is some information about the reclamation
project in Central District and Wan Chai. Study
carefully and answer the following questions.
21 4. What are the objectives of the Central and
Wan Chai Reclamation Project? ________________
_________________________ ______________________

The reclaimed land is designated for
transportation and recreational land uses.
225. Recently, there has been a heated debate on
the proposed reclamation in Central and Wan Chai.
There are different views expressed in the
community about the benefits and costs of the
reclamation. Below is a summary of groups who
support or object to the project.
23 5. a. What are the views of those people who
support or object to the reclamation?
- Provide land for housing, community facilities
and other uses - Expand the area of CBD and facilitate commercial
activities - Provide land for transport facilities, such as
the Central-Wan Chai Bypass, in order to solve
the problem of traffic congestion - Develop promenade that will attract tourists and
the public - Other reasonable answers
- The size of harbour becomes smaller and
artificial - Shrinked harbour increases the chance of sea
accidents - Dredging sands will pollute the harbour water
quality becomes worse - Dredging of sea bed will cause marine organisms
to die because of lack of oxygen - Other reasonable answers
24 5. b. According to these different views, what
is the major conflict in the harbour
reclamation issue? ____________________________

________
It is the conflict between urban development and
environmental conservation.
6. Does urban development always conflict with
environmental conservation? ________________

25Basic Principles of Urban Planning
- To provide land to meet the demand for
residential, commercial, industrial,
transportation, community, and recreational uses - To ensure compatible and orderly patterns of land
uses - To provide the right developments in the right
places at the right time
26Basic Principles of Urban Planning
- To balance different competing demands upon
scarce land resources - To promote sustainable development
- To conserve the natural environment and preserve
over cultural heritage - To use land resources sustainably, effectively
and efficiently
27Basic Principles of Urban Planning
- To avoid delay in land development processes
- To encourage public participation in the planning
process - To protect the public interest

29There are building height restrictions of no more
than 60 m in shaded areas. Explain
- The major aim of restricting the building heights
is to preserve the harbour view. - Restrict heights of the buildings can lower
building density, - ensure buildings away from the waterfront can
enjoy the sea view as well. - Ensure the flow of air / air circulation / avoid
air pollution
30What are the advantages of constructing the
proposed Harbour Park ?
- Supply of recreational land use to meet peoples
needs. - Harbour Park is constructed near the centre of
Victoria Harbour, which allows people to enjoy
the sea view from a closer point. - It becomes a new tourist attraction which can
promote Hong Kongs tourism. - Lower the density of development / more open
space and green area
31Do you think the following groups would support
or oppose the reclamation project in Wan Chai?
- Land developers support.
- It is because reclamation in Wan Chai increases
supplies of land in Central Business District
(CBD). - Land developers can build high value commercial
buildings and make large profits. - It also provides land to build new roads which
can ease the traffic congestion problem, - favouring business development and land price
increases.
32Do you think the following groups would support
or oppose the reclamation project in Wan Chai?
- Environmentalist oppose.
- It is because reclamation project involves
dredging of seabed, which releases toxins in
sludge. This disturbs marine ecology and a lot of
marine organisms or fishes will die. - It also narrows down Victoria Harbour and
increases the risk of sea traffic accidents. - Further reduction in the size of Victoria Harbour
affects the beauty of the sea. - The reclamation project also causes water, air
and noise pollution
33What can the Government do?
