Rising demand for land in Singapore
Why does Singapore needs more land?
![Page 4: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/4.jpg)
Why do we need more land?
Land Scarcityo Population is about 4.8 milliono Population density is about 6000
persons per square kilometers

Singapore’s populatoin hit 4.84 million in June this year, marking a 5.5 per cent increase from a year before. The number of non-residents grew by 19 per cent, while the resident population went up by a mere one per cent. In other words, non-residents are ¼ portion of Singapore population.

Why do we need more land?
Population growtho Results in growing industries and
businesseso Spatial constraints = problem of
not having enough space

Creating more land
…the Landfill Method
![Page 8: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/8.jpg)
Landfill method
• Landfill method is used to create dry land from waterlogged areas by filling them with sand to form dry land.
Waterlogged area = area that is soft and watery
![Page 9: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/9.jpg)

Stage 2: Sand wall is built around the area to be reclaimed to keep the sea water out. Sand is also stored into the sea just outside the sand
wall until it is needed.

Stage 4: Sand is compressed and granite wall is built on the side facing the sea to
prevent waves erosion.

Is the landfill method effective?
What are the advantages and
disadvantages?
![Page 15: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/15.jpg)
Effectiveness of Land ReclamationEffectiveness of Land Reclamation
• Successful way of increasing countries’ land area.
• Can only reclaim land up to 15m in depth as more sand will be needed
• Limit to the amount of land that can be reclaimed
• Coastal habitat affected
Advantages Disadvantages
![Page 16: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/16.jpg)
Landfill method in Singapore
• In recent years, sea sand obtained from the seabed is the main source of fill materials for reclamation. Sand is imported from the neighbouring countries such as Indonesia.

Maximize use of existing land
…using our land as much as possible
![Page 18: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/18.jpg)
Maximizing URBAN landuse1) Mixed landuse• Mixed landuse means having
shopping malls, offices, houses and hotels in one area – linked by pedestrian walkways
• Landuse planning is the process whereby different areas on a piece of land are assigned for different landuses (i.e. malls, houses, schools)
![Page 19: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/19.jpg)
Effectiveness of Mixed LanduseEffectiveness of Mixed Landuse
• Convenience of having homes, jobs and wide range of services in the same area
We do not need to travel far!
• Mixed landuse requires construction and reconstruction of new and old buildings as well as transport networks
• Places near industries may encounter traffic congestion
• Air and noise pollution in housing area
Advantages Disadvantages
![Page 20: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/20.jpg)
Maximizing URBAN landuse
2) High Density Building: Building that consists of many living or working people per unit area
Pinnacle@Duxton is a 50-storey HDB’s first 50-
storey integrated public housing development
from HDB.
There are many people living on this piece of land!
![Page 21: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/21.jpg)
Effectiveness of High Density BuildingEffectiveness of High Density Building
• With more people on a small piece of land, more land are freed for other purposes.
• Crowded environment, traffic congestion – may increase stress levels among people
Advantages Disadvantages

Future of Singapore?
![Page 23: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/23.jpg)
Future of Singapore?
Limitations of technology• Current technology only
allows us to reclaim land from waters up to 15 metres in depth
Expensive• Not enough sand from
within Singapore• Importing sand is costly
![Page 24: Land Supply in Singapore E-Learning @ home 18 th August 2010](https://reader035.vdocuments.net/reader035/viewer/2022062511/55143784550346ec488b629c/html5/thumbnails/24.jpg)
Future of Singapore?
Territorial constraints• Need to keep certain amount of sea space for
shipping activities• To maintain good relationships with neighbours
without infringing on neighbours’ territories
We cannot keep reclaiming on the northern part of Singapore
because of the land of Malaysia.

…Malaysia’s concern.

Future of Singapore?
• We will carry on with landuse planning and build high-density buildings to cope with the increasing population.
