  • CHONG BOON SECONDARY SCHOOL Lower Sec Geography Secondary Two Unit 12: Responses to the Rising Demand for Land COPY
  • Thinking Questions 1.Can we ‘make’ more land? COPY
  • Unit Objectives 1.Evaluate the effectiveness of different responses to increase land supply. COPY
  • Increasing Price of Land •How much is the cost of your home? •Cost PSF (per square feet) •HDB flat •Condominium in AMK •Condominium near Sentosa COPY
  • How much do you think this house cost?
  • The price mechanism •Controls the allocation of land use. •Process which determines the pricing of products. •Landuse price determines the type of use. •Land nearer to CBD is more expensive. (Central Business District) COPY
  • Opportunity Cost •The cost (money or non- monetary) of choosing a decision as opposed to another choice. •“The lunch dilemma” COPY
  • What is for lunch? I have $5, what
  • Cost of conservation •Conservation of historical building in Singapore has a high opportunity cost. •Valuable land space in CBD area. •Replacement with a new skyscraper will bring more profit. COPY
  • A conservation area in Singapore
  • Land Clearance •Deforestation: removal of forested areas for use by humans. •Residential / Commercial / Agricultural •Very rapid rate of deforestation •1850 (20 million sq km of rainforest) •2005 (9-12 million sq km of rainforest left) COPY
  • Deforestation Video
  • Commercial logging •Exploitation by large logging companies •Logging for wood to meet global wood demands • Furniture, housing, paper,. • Rising global wealth leads to higher demands for wood products COPY
  • Agricultural use •Higher global demand for meat •Need for land to do commercial ranching. •Forests cleared to give space for herding. •Commercial Farming (cash crops) •Oil Palm, Corn/Maize/Wheat, etc. COPY
  • Effects of Deforestation •Loss of Habitat (Animals) • Native animals lose habitat • Move nearer to humans, lead to conflict, hunted down. •Loss of Habitat (Plants) • Destroyed together with rainforest • Loss of plantlife that may have undiscovered potential COPY
  • Effects of Deforestation cont’ • Soil Erosion • Removal of rainforest leads to higher drainage • Rain brings the topsoil (fertile soil) away • Nutrients now loss and land unable to support plants. • Greenhouse effect • Rainforest helps to recycle Carbon Dioxide (CO2) into Oxygen • Loss of rainforest introduces more CO2 (a greenhouse gas) into the atmosphere. • This will lead to global warming. COPY
  • Maximising Land Use •There is a limit to reclaiming land. •Land use management is done with land use planning. •Urban and Rural land use COPY
  • Urban Land Use •Mixed land use • Combine residential and commercial use • Shophouses • SOHO (Small Office Home Office) COPY
  • Urban Land Use •High-density building • Skyscrapers and super skyscrapers • Saves ground space • Commonly found in Business Centres. COPY
  • Rural Land Use (Agriculture) •3 key ways to maximise arable land •Terracing •Soil-less farming •Irrigation COPY
  • Terracing •Converting hills into flat steps. •Cultivation carried on the steps. •Commonly done for wet rice in South East Asia COPY
  • Soil-less farming • High tech farming methods • Hydroponics • Plants grown by submerging their roots in nutrient solution. • No soil needed, if done in a greenhouse, artificial sunlight can be used. • Aeroponics • Plants grown by suspending them in the air and spraying nutrient solution onto the roots. • No soil needed, if done in a greenhouse, artificial sunlight can be used. COPY
  • Irrigation •Introduction of fresh water into drylands •Create arable land from desert areas. •Supplement (help) areas with seasonal / unreliable rainfall. •Enable double / multiple cropping. COPY
  • Land Conservation •Land as a nature reserve •Government Policies •Land Reclamation COPY
  • Nature Reserve • Protected land area • Flora and fauna (plants and animals) found inside are protected by law • Anti-poaching laws • Recognition of nature as part of the country’s natural heritage. • Bukit Timah Nature Reserve, Yellowstone National Park, etc. COPY
  • Government Policies •Government imposes landuse policies that restrict certain uses for conservation. •Valuable land is properly planned and used for development. •Less wastage of valuable land. COPY
  • Land Reclamation (Singapore) •Refer to image on pg 110. •Reclamation has taken place on all except North and North-West coast. •Offshore islands reclaimed to form larger islands / merge to form usable islands. COPY
  • Land Reclamation (Singapore) •Entire East Coast Park is reclaimed. •East Coast Parkway Expressway once sat in the sea. •Landfill method is used to reclaim land from the sea. COPY
  • Land Reclamation (overseas) •United Arab Emirates (Dubai) • The Palm Island Resort • Landfill method. • Palm tree shaped resort. COPY
  • Thinking again “Can we reclaim forever?” Singapore 2080
  • Mind-mapping time Landfill Method Increasing land supply Draining swamps Increasing price of land Reclaiming derelict land Conservation of land Urban land use Responses to the rising demand for land Empoldering Land reclamation Agricultural land use Maximising land use COPY
