    • Understanding Land Supply Chapter 11: Explain the reasons for land constraint
    • Understanding…
      • Rapid increase in population has put a
      • great strain on the Earth’s limited land
      • space.
      • Countries that experience land
      • constraint then created land by the
      • process of land reclamation.
    • Land As A Scarce Resource
      • Land = surface area of Earth w/o oceans, seas, lakes and rivers
      • 10% of its surface is habitable
      • > 6 billion people living
      • Many needs need to be met with the supply of limited land space
      • Build houses, grow crops and set up industries on this limited land we have.
    • Why only 10%?
      • 70% is water
      • 5% is too cold
      • 5% is too
      • mountainous
      • 10% is too dry
      • Thus, only 10%
      • is habitable
    • Competition For Different Land Uses
      • Land scarcity = the shortage of land available for economic activities
      • Land scarcity results in competition for available land
      • Land is required for industries, agriculture, housing, recreation and transportation
    • Competition For Different Land Uses
      • Plot of land is prime land; Should build banks and offices (commercial centre, offices) [Commercial]
      • Patch of forest cut down to build highway to improve transport system (roads, airport) [Transport]
      • Recreation (parks, gardens) is needed for people to relax in [Recreational]
    • Competition For Different Land Uses
      • Housing for people to stay in/shelter (towns, cities, villages) [Residential]
      • High demand of crops (rear animals); insufficient land [Agriculture]
      • Industries (factories) to create jobs for people to live in and to bring in more $ for the country [Industrial]
    • Reasons For The Rising Demand Of Land
      • Increase in population
      • > 6 billion
      • 1960=2392 people per km 2
      • 2004=6066 people per km 2
      • More land is needed for housing and growing of crops
    • Reasons For The Rising Demand Of Land
      • Singapore (1960s); public housing programme host by government
      • Tall buildings built to house the increased population
      • Shortage of farmland (common in developing countries)
      • India; 55% live in rural areas, causing great pressures on the farmlands
    • Reasons For The Rising Demand Of Land
      • Increased urbanisation = increase in the percentage of urban centres and in the percentage of people living in urban centres
      • This era of globalisation, most countries focus on economic development to gain a competitive edge in the world market
    • Reasons For The Rising Demand Of Land
      • Results are urbanisation and the formation of megalopolises (a very large metropolitan area) like New York-Philadelphia
      • Urban centres need more land to build residential, industrial and commercial areas
      • Land is needed for roads, railways and container wharves
      • Competition of land by other land uses becomes keener and hence less land becomes available farming due to increased urbanisation
