Year09-10 Geog Sabah Field Trip
04-07Dec2009
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.
Ecotourism
• Ecological tourism1. See the beautiful scenery2. Raise the public awareness
Examples in Sabah
Proboscis Monkeys
Fireflies
Canopy Forest
Coral Beach
national parks
source of income for medical use and studying Fallowing period for destroyed plants Retain more plant and animal species.
Performances in Cultural Village
• Mixture of Education & Entertainment• Culture Conservation• Life of People
Pollution
• River Klias: water pollution• Air Pollution, Noise Pollution
Affect flora & fauna there
national parks
Human disturbance Pollution Emission from
vehicles Road building
Deforestation
Soil erosion
♠ No more tree roots binding the soil together
Short-term Effects on Hydrological Cycle
↑ Surface runoff
↑ Discharge
↑ Flooding
Long-term Effects on Hydrological Cycle
↓ Transpiration
↓ Precipitation
↓ Base flow
↑ Drought
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 !!!
