Transcript Distribution of Resources

Distribution of Resources
What one characteristic is shared
between the three types of
resources?
Uneven Distribution
• LLDC’s have 75% of the world’s
population but only 17% of the world’s
GNP.
• Most of the world’s resources are
controlled by a tiny fraction of its
inhabitants.
• In LLDC’s, 80% of land is owned by 3% of
the landowners.
• Landless labourers make up the largest
percent, many work long hours for other
people and usually live a life of poverty.
• In some cases, the causes for this uneven
distribution of resources are natural.
• This is due to climate, geological history
and physiography.
• Physiography is the natural features of the
earth’s surface.
Land Resources
Factors that affect the distribution of agricultural resources
are climate, relief, geology and human settlement.
Refer to figure 9.15 on pg. 222 in Global Connections.
Which areas of the world have no agriculture taking place?
What might be the reason?
• Far North = extremely short growing
seasons which results in little
to no crops
• Desert area (Africa, Asia, Australia) =
extreme heat and lack of rainfall make
farming impossible
Relief
• Determined by the areas elevation and
slope.
Lapse rate = rate at which the temperature
falls with increasing temperature.
Why do areas with mountainous elevations
have limited agricultural value?
Geology
• Allows us to become aware of the minerals that
are present in different soils and provide
nutrients for plant growth.
ie. Pineapple plantations thrive in the rich
volcanic soils in Hawaii
Grasses seeding themselves
and growing very quickly on
Mount St. Helen after its major
eruption in 1980.
Population Density
• Traditionally, areas considered to as ideal
for farming have become highly populated.
• Once a city is established and begins to
grow, the farmland is pushed farther and
father away.
Ie. North east coast of the
USA, river valleys in
India and China.
Types of Farmland
There are three classes of agriculture which
are based upon a farm’s profitability:
1. Commercial farming
2. Small holding
3. Subsistence farming
Commercial Farms
• Commercial farms and ranches are large
enterprises
• Uses the most advanced equipment
• Operate with the objective of turning a
healthy profit
Which regions of the world fall into this
class?
Subsistence Farms
• Farms for survival
• Farmer and immediate family provide most of
the labour as machinery and technology are not
readily available
• Farmland usually is very small and situated in
the least desiereable areas: scrubland, hilly,
steep sloped or jungle areas.
Small Holding Farm
• Falls in between the comercial and
subsistance farmer
• Use a combination of
machinery and livestock to cultivate
• Consume part of their crops and sell the
rest for cash
Where are the majority of these farms
located?
