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