1HIGHER GEOGRAPHY HUMAN - RURAL
Lets now look at the three case study farming
types.
- They are called-
- SHIFTING CULTIVATION
- INTENSIVE PEASANT FARMING
- EXTENSIVE COMMERCIAL FARMING
- You will need to know-
- An example of where each type is practiced
- What the landscape looks like
- How each type works the good and bad aspects of
it - The changes that have been affecting it, and how.

Global Distribution of Shifting Cultivation
3HIGHER GEOGRAPHY HUMAN - RURAL
Shifting cultivation is practiced in the
Equatorial Rainforest areas of the world. An
example is the Boro Indian tribe in Amazonia-
Brazil, South America.
4HIGHER GEOGRAPHY HUMAN - RURAL
- This type of farming is subsistence, extensive,
low technology, peasant, low productivity, labour
intensive, mainly arable. - It is practiced by between 3 and 6 extended
families -perhaps twenty to fifty people- who
live and farm together. - They use a huge area of rainforest for their
farming, but only small amounts at any one time. - It relies on leaving the land empty- fallow- for
many years to recover after use. - The area of rainforest is traditionally handed
down to the next generation no-one actually
owns the land.
5HIGHER GEOGRAPHY HUMAN - RURAL
The land is lush with dense vegetation cover, but
it is very fragile! Stop the cycle of nutrients
and the soil is easily ruined! The native indians
know how to work the land without spoiling it in
the long term. This is called SUSTAINABLE, and
it is good!
6HIGHER GEOGRAPHY HUMAN - RURAL
What are the processes involved in Shifting
farming?
- The group decide to settle in an area- it could
be several hectares in size. - They build a large, communal hut called a MALOCA.
- The men chop the smaller trees down with axes and
machetes. - Useful trees like bananas and pineapples are
left. - The larger trees are left to help bind the soil
and to provide shade they are too hard to
remove, anyway!

SLASH AND BURN is used to clear
the land.
Some trees such as the banana tree might be left
standing. Why?
Why is this better than chopping the trees down
and removing them?

6. The women and children burn the chopped wood-
it adds ash as a weak fertiliser, though this is
quickly washed out of the soil by the rain. 7.
The women then plant their gardens called
CHAGRAS between the stumps in a random, irregular
way. 8. They weed and tend the plants over the
next few months, and can harvest up to three
crops a year. Remember there are no seasons in
the rainforest, and there is continuous growth!
9. All the work is done with digging sticks,
hoes and machetes- very low technology!
14HIGHER GEOGRAPHY HUMAN - RURAL
..the cut down trees are allowed to dry for three
months or so, then burned, in small, controlled
fires.

Ground clearance is very hard work, so many
stumps, branches and roots are left.
17HIGHER GEOGRAPHY HUMAN - RURAL
The burned wood adds ash (a natural fertiliser)
to the soil.

In this Chagra, -a garden rather than a field-,
maize seeds are being planted amongst Sweet

Maize (corn) may be grown where the soils are
richer.
Papaya and other fruits form an important part of
the diet.
22HIGHER GEOGRAPHY HUMAN - RURAL
Other crops may include
- Yams
- Tobacco
- Coca
- Mangoes
- Beans
Domesticated animals such as pigs and chickens
may also be kept.
23HIGHER GEOGRAPHY HUMAN - RURAL
However, the torrential rains cause rapid
leaching of the already poor soils, washing vital
minerals out of the soil and reducing its
fertility. This is why the clearings are only
used for a few years.
Unless the land is left fallow (rested) to
recover these nutrients, it will be permanently
degraded.
LEACHING by rain.
24HIGHER GEOGRAPHY HUMAN - RURAL
After a few years, the crops start to fail and
the clearing is abandoned to be reclaimed by
the forest.

Forest cleared by slash and burn method. The
ash acts as a fertiliser

This farming does not lead to serious destruction
as it allows the forest to naturally regenerate.
Food crops such as manioc, sweet potatoes and
maize are grown. The diet is supplemented by
hunting, fishing and gathering food from the
forest.
River sites are good for fishing and transport
26Shifting village and cultivation
HIGHER GEOGRAPHY HUMAN - RURAL
27HIGHER GEOGRAPHY HUMAN - RURAL
The settlement pattern is dispersed or scattered.
Because of the large area of forest required with
all of these moves, the overall population
density is very low often less than 1 person
per sq.km.
28HIGHER GEOGRAPHY HUMAN - RURAL
There is a variation on this type of farming
BUSH FALLOWING is where the group settle in one
area, living in a permanent maloca for very much
longer than usual. They grow their crops in
fields around the settlement. To stop the soil
getting ruined too soon, they practice CROP
ROTATION. This is where they use a different
field each time for a different crop. They
usually leave some of the fields FALLOW to let
them recover a bit. See the booklet, pages 12/13.
29Changes 1
HIGHER GEOGRAPHY HUMAN - RURAL
- Shifting cultivation is in danger of
disappearing - This is due to destruction of large areas of the
rainforest on which this system depends the
area available is rapidly shrinking - This is caused by logging companies, cattle
ranchers, gold and diamond miners and other
mineral hunters, and new settlers moving in to
the forest - Population growth is also putting additional
strain on this way of life particularly in west
Africa.
See Booklet P10/11

Changes 2
Some Indian groups have been forced into
reservations or retreated into more remote areas
deep in the forest many tribes have suffered
from Culture Shock There has been violence and
intimidation against these tribes, with many
thousands killed by new settlers Thousands have
also died due to lack of immunity to western
diseases such as measles There has been serious
water pollution by gold mining, which uses toxic
substances such as mercury. This has caused
poisoning of rivers and people.
31HIGHER GEOGRAPHY HUMAN - RURAL
In Brazil, for example, the building of the Trans
Amazonian Highway has opened up the virgin
rainforest to settlement and exploitation, often
with disastrous consequences for the shifting
cultivators.

Huge fires now destroy enormous areas in a few
hours.
Shifting cultivation is abandoned and replaced by
large, often foreign owned schemes.

36Review of Main points
HIGHER GEOGRAPHY HUMAN - RURAL
- Shifting Cultivation is also known as slash and
burn - It is found mostly in the equatorial rainforest
areas of the world e.g. Amazon, Congo, PNG. - It has several versions, including bush
fallowing - It is low technology
- It supports a very low population density
- Its settlement pattern is dispersed
- It is subsistence farming, with little surplus
- It is under threat due to a combination of
outside influences. Detailed knowledge of these
forces of change is essential.
