  • 4. Types of farming
  • 5. Physical problems of farming • Too much water - flooding. Crops & animals are washed away Eg Bangladesh • Not enough water – drought often associated with desertification eg Sahel zone in Africa • Soil erosion – caused by drought but also poor farming techniques
  • 6. Average rainfall in the Sahel Rainfall below average – desert advances Rainfall above average – desert retreats Why did farmers in West Africa begin to grow more crops in the early 20th century? What happened in the 1970’s?
  • 7. Desertification
  • 8. Human problems of farming • Vicious circle of poverty – no money for investment • Lack of education about good farming techniques • Low use of technology • Cash crops grown on best quality land so countries have to import food • Fluctuating prices
  • 9. Ways of helping farmers in LEDCs
  • 10. Rice farming in Sri Lanka
  • 11. Rice growing in the padi field
  • 12. Harvest by hand
  • 13. Physical inputs • The farm is on flat land on the floodplain of the river • Size - 2 hectares • Fertile, alluvial soils • Average temperature is 28o C • Average rainfall 1,000mm • Manure from the oxen is used to fertilise the fields
  • 14. Human inputs • The labour on the farm consists of Mr Silva, his wife and 3 children • No machinery so all work is manual • The family own an ox which is used to plough the fields. They hire this out to other villagers to earn extra cash.
  • 15. Outputs • 2 crops of rice are grown each year. The yield is approximately 100 kilos per hectare. • Manioc and sweet potatoes • Vegetables such as chilli and cabbage are grown in a small garden by the house.
