Man-Land Interaction

colonial exploitations

Lumbering rapid depletion Land used for oil palm plantations could not b

e used after land abandonment. (acidic soil)

Biodiversity loss Loss of habitat Some animals were taken to Europe as pets Nutrient cycle was disrupted.

Plantation

an agricultural activity that crops are grown mainly for sale in distant markets, rather than for local consumption.

Examples of plantation

Rubber TreesCoffee Tree

TobaccoCotton

Examples of plantation

Tea Plantation

Sabah Tea Garden

Tea Product

natural trees near the plantation fields will easily die without self-regulatory system

Biodiversity loss

a) food chain is damaged b) living area is reducedc) extinction of animals

Loss of habitat

Monoculture damages nutrient cycle

depletion of soil nutrient

The infertile soil is unfavorable for growing plants○ Primary vegetation secondary vegetation

Bare Land ○ no trees roots binding the soil soil erosion + desertification

Agroforestry

Integrated farming approach Aim: 1.getting resources needed 2.conserving the environment

Tree bark pencil cases

Cause little harm to treesA source of income of local people

Terrace farming

Aim : prevent soil erosion and surface runoffA soil conservation method

Sabah tea

Grow on foothills of Mt KinabaluOrganic farming : No chemical fertilizers or

pesticides

Kerosene nuts

• Can be a kind of bio-diesel

Fire!

Kerosene !!! Amazing !!!
