shifting cultivation
Storyboard Tekst
- The tribes cut down the trees using hand tools.
- After the trees are dried they are burnt. This removes the weeds and roots to provide natural fertilisers.
- The area is now has been planted, with things like manico, rice and pumpkins. This gives the tribes cash crops.
- As soon as the trees have been cleared the soil starts to loose its fertility as the heavy rain washes away the nutrients out of the soil.
- The soil is now poor, the crops stop growing.
- Tribes now need to move to a new area.They need to go back to step one.
- After 20-25 years the land can be farmed again.
