Title: Patterns of natural resources


1
Patterns of natural resources
  • The uneven global distribution of resources

2
  • There are disparities in the access to natural
    resources between and also within countries. The
    uneven global distribution and consumption may be
    analysed under the following resources
  • forests
  • water
  • minerals
  • energy

3
Forests
  • Forests are a particularly important resource for
    rural populations since they are a source of
    fuel, food and building materials. Developing
    countries in the appropriate tropical climate
    possess most of the worlds forest coverage (i.e.
    Brazil, Indonesia, etc.) however, it is these
    very countries that are experiencing the highest
    deforestation rates.
  • It is predicted that the Amazon forests would
    have disappeared by the end the this century.

4
Forests
  • Most wood in Africa, South America and Asia is
    used for fuel while in North America, Europe,
    Oceania and the former USSR it is produced for
    industrial purposes (paper products, furniture,
    etc.).

5
Forests
  • About half of the worlds roundwood timber is
    removed by the six top producers The US, former
    USSR, China, India, Brazil and Canada. The
    developing world figures only marginally in the
    global trade of forest products except for its
    massive exports of hardwoods. Clearly, the
    developing countries export more than they
    import.

6
Forests
  • The increased global demand for wood and the
    continual clearing of land for cultivation has
    often led to ecologically unsustainable
    harvesting of forests in many developing
    countries. Between l981 and l990, l5.4 million
    hectares of tropical forests were removed each
    year.

7
Water
  • The worlds greatest concentration of freshwater
    is in the high latitudes-in the glaciers of
    Antarctica and Greenland and in the lakes of the
    former USSR and North America, areas with very
    low populations. Areas close to the equator also
    have a large proportion of the worlds freshwater
    supplies-the tropical humid zones of South and
    South-East Asia, and the Amazon Basin. Areas with
    limited supplies include the mid latitudes-Middle
    East, North Africa, northern Central Asia and
    Central Australia.

Water
  • Asia has the largest amount of annual internal
    renewable water resources(10,485 cubic
    kilometres), followed by South America(10,377).
    When the water resources are divided by
    population, Oceania leads the amount followed by
    South America, North and Central America then the
    former USSR.

10
Water
  • On the consumption side, Africa and Asia use most
    of their water for agricultural needs(88 and 86
    respectively). Europe and North America have the
    greatest industrial proportions of water use(54
    and 42 each). Oceania uses 64 of its water for
    domestic purposes.
  • Asia dominates the average annual catches of
    marine and freshwater resources.

Minerals
  • There is no consistent natural dispersal of
    mineral wealth around the globe. However, the
    CIS (the former USSR, Lithuania, Latvia, Estonia
    and Georgia), Australia and China are three major
    mineral producing nations. North America, Europe,
    Japan and China consume the majority of these
    reserves.

14
Energy
  • Most energy is required for 3 basic purposes
  • 1. electricity(coal, oil, uranium, solar,
    etc.),

  • 2. industry (eg. Coal for steel
    production),
  • 3. fuel for transportation.

15
Energy
  • Energy resources are unevenly distributed,
    Australia and the US exporting most of the
    worlds coal and Canada and Australia for
    uranium. The OPEC group of nations(Saudi Arabia,
    Kuwait, Iran, Iraq, Libya, etc.) is the major
    bloc of oil producing nations as well as the
    former USSR, Western Europe and North America.
    Due to their high levels of fuel needs, Western
    Europe and North America are still net importers
    of oil.
