Rising demand for land in SingaporeWhy does Singapore needs more land?
Why do we need more land?Land ScarcityoPopulation is about 4.8 millionoPopulation density is about 6000 persons per square kilometers
Singapores 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 portion of Singapore population.
Why do we need more land?Population growthoResults in growing industries and businessesoSpatial constraints = problem of not having enough space
Creating more landthe Landfill Method
Landfill methodLandfill 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
5 stages in total
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 1: Piles are forced into the seabed to make it stable
Stage 3: Sand is sucked up and pumped into the enclose area.
Stage 4: Sand is compressed and granite wall is built on the side facing the sea to prevent waves erosion.Stage 5: Vegetation are grown on the reclaimed land to prevent soil erosion and the land is left to rest.
The shaded parts represent areas that are reclaimed. Singapore has increased its land supply!
Is the landfill method effective?What are the advantages and disadvantages?
Effectiveness of Land ReclamationSuccessful way of increasing countries land area.Can only reclaim land up to 15m in depth as more sand will be neededLimit to the amount of land that can be reclaimedCoastal habitat affectedAdvantagesDisadvantages
Landfill method in SingaporeIn 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 landusing our land as much as possible
Maximizing URBAN landuse1) Mixed landuseMixed landuse means having shopping malls, offices, houses and hotels in one area linked by pedestrian walkwaysLanduse planning is the process whereby different areas on a piece of land are assigned for different landuses (i.e. malls, houses, schools)
Effectiveness of Mixed LanduseConvenience 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 networksPlaces near industries may encounter traffic congestionAir and noise pollution in housing areaAdvantagesDisadvantages
Maximizing URBAN landuse2) High Density Building: Building that consists of many living or working people per unit areaPinnacle@Duxton is a 50-storey HDBs first 50-storey integrated public housing development from HDB.
There are many people living on this piece of land!
Effectiveness of High Density BuildingWith more people on a small piece of land, more land are freed for other purposes.Crowded environment, traffic congestion may increase stress levels among peopleAdvantagesDisadvantages
Future of Singapore?
Future of Singapore?Limitations of technologyCurrent technology only allows us to reclaim land from waters up to 15 metres in depthExpensiveNot enough sand from within SingaporeImporting sand is costly
Future of Singapore?Territorial constraintsNeed to keep certain amount of sea space for shipping activitiesTo maintain good relationships with neighbours without infringing on neighbours territoriesWe cannot keep reclaiming on the northern part of Singapore because of the land of Malaysia.
Future of Singapore?We will carry on with landuse planning and build high-density buildings to cope with the increasing population.
The End. :)
