  • 1. HIGHER GEOGRAPHY HUMAN - RURALLets now look at the three casestudy farming types.They are called;-SHIFTING CULTIVATIONINTENSIVE PEASANT FARMINGEXTENSIVE COMMERCIAL FARMINGYou will need to know;-An example of where each type is practicedWhat the landscape looks likeHow each type works; the good and bad aspects of itThe changes that have been affecting it, and how. 1

HIGHER GEOGRAPHY HUMAN - RURALShifting cultivation is practiced in the EquatorialRainforest areas of the world.An example is the Boro Indian tribe in Amazonia-Brazil, South America.3 4. HIGHER GEOGRAPHY HUMAN - RURALThis type of farming is subsistence, extensive, lowtechnology, 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 farmtogether.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 manyyears to recover after use.The area of rainforest is traditionally handed down tothe next generation; no-one actually owns the land.4 5. HIGHER GEOGRAPHY HUMAN - RURALThe land is lush with dense vegetation cover, but it isvery fragile! Stop the cycle of nutrients and the soilis easily ruined!The native indians know how to work the land withoutspoiling it in the long term.This is called SUSTAINABLE, and it is good! 5 6. 6 7. HIGHER GEOGRAPHY HUMAN - RURAL What are the processes involved inShifting farming?1.The group decide to settle in an area- it could beseveral hectares in size.2.They build a large, communal hut called a MALOCA.3.The men chop the smaller trees down with axes andmachetes.4.Useful trees like bananas and pineapples are left.5.The larger trees are left to help bind the soil andto provide shade; they are too hard to remove,anyway! 7 8.

The women and children burn the chopped wood- itadds ash as a weak fertiliser, though this is quicklywashed out of the soil by the rain.7. The women then plant their gardens calledCHAGRAS between the stumps in a random, irregularway.8. They weed and tend the plants over the next fewmonths, and can harvest up to three crops a year.Remember there are no seasons in the rainforest, andthere is continuous growth!9. All the work is done with digging sticks, hoes andmachetes- very low technology! 14 15.

HIGHER GEOGRAPHY HUMAN - RURALShifting village and cultivation27 28. HIGHER GEOGRAPHY HUMAN - RURAL The settlement pattern isdispersed or scattered.Because of the large areaof forest required with allof these moves, the overallpopulation density is verylow often less than 1person per sq.km.28 29. HIGHER GEOGRAPHY HUMAN - RURALThere is a variation on this type of farming;BUSH FALLOWING is where the group settle in onearea, living in a permanent maloca for very muchlonger than usual.They grow their crops in fields around thesettlement.To stop the soil getting ruined too soon, theypractice CROP ROTATION. This is where they use adifferent field each time for a different crop.They usually leave some of the fields FALLOW tolet them recover a bit. 29 30. rotational bush fallowing Continuously cultivatedarea around village 162 Outer clearings farmed in rotation Village53430 31. 1. What is a cash crop? What term means the opposite of this?2. What are the differences between intensive and extensive farming? Give an example of a British farm type for each.3.Name the example place from the slides where shifting cultivation is practiced.4. Describe the amount of land each group uses over the whole time. Compare this to how much is used at any one time.5. Who makes up the group who farm together? How many might there be? What density of population can they provide for?6. Describe their house in some detail.7. What do they need to do to the land before they can plant crops? How do they do this?8. What other name is given to this practice?9. Name six crops they grow. How do they supplement their diet? Give two ways.10.Describe examples of the technology they use.11.What makes them move to another area? Explain why this happens.12.Why does bush fallowing sometimes get done instead of the original practice?13.Name and describe briefly six different reasons 31 their farmingfor type changing. 32. HIGHER GEOGRAPHY HUMAN - RURAL Changes 1 Shifting cultivation is in danger of disappearing; This is due to destruction of large areas of therainforest on which this system depends thearea available is rapidly shrinking; This is caused by logging companies, cattleranchers, gold and diamond miners and othermineral hunters, and new settlers moving in tothe forest; Population growth is also putting additional strainon this way of life particularly in west Africa.32 33. HIGHER GEOGRAPHY HUMAN - RURALChanges 2Some Indian groups have been forced into reservations orretreated into more remote areas deep in the forest;Many tribes have suffered from Culture Shock;There has been violence and intimidation against thesetribes, with many thousands killed by new settlers;Thousands have also died due to lack of immunity towestern diseases such as measles;There has been serious water pollution by gold mining,which uses toxic substances such as mercury. This hascaused poisoning of rivers and people. 33 34. HIGHER GEOGRAPHY HUMAN - RURALIn Brazil, forexample, the buildingof the TransAmazonian Highwayhas opened up thevirgin rainforest tosettlement andexploitation, oftenwith disastrousconsequences for theshifting cultivators. 34 35. HIGHER GEOGRAPHY HUMAN - RURALMassive deforestation is removing the habitat on which shifting cultivation depends, as here in Brazil.35 36. HIGHER GEOGRAPHY HUMAN - RURAL Huge fires now destroy enormous areas in a few hours.Shifting cultivation isabandoned and replaced bylarge, often foreign-ownedschemes. 36 37.

HIGHER GEOGRAPHY HUMAN - RURALThousands of garimpeiros(illegal gold miners)devastate an area ofrainforest in a desperatesearch for gold. 38 39. HIGHER GEOGRAPHY HUMAN - RURAL Review of Main points Shifting Cultivation is also known as slash and burn; It is found mostly in the equatorial rainforest areas ofthe 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 outsideinfluences. Detailed knowledge of these forces ofchange is essential. 39
