Name key geographical facts about Malaysia
67% of Malaysia's land is covered by rainforest.
The natural vegetation in Malaysia is tropical rainforest
Malaysia is part of the Middle East
Malaysia consists of East Malaysia, part of the island of Borneo and the Malaysian Peninsular.
What is deforestation?
A form of slash and burn farming
The planting on new trees and pants
The cutting down and removal of forest
Material transported by a river
What are the main threats to Malaysia's rainforests?
Logging and mineral extraction
Population pressure
Energy supply
Commercial and subsistence farming
What is subsistence farming?
Large scale farming operations often completed by large companies
Plantation owners who receive tax incentives.
Farming of both cattle and crops
Small scale farming, for your own needs, with little to sell, often referred to as sustainable.
Why is mineral extraction a threat to Malaysian TRF?
Mining of tin and smelting is common polluting the local environment
TRF has been cleared for mining and road construction reducing biodiversity.
Drilling for oil and gas has started on Borneo leading to more loss of TRF and contamination of local water supplies
TRF cleared for construction of new housing and motorways.
Why is logging a threat to the Malaysian TRF?
Malaysia is the world's largest exported of tropical wood.
'Clear felling' where all trees are felled was common leading to total destruction of forest habitats.
Selective logging has replaced 'clear felling' however trees are still being destroyed at an unsustainable rate.
Trees are set aside to increase biodiversity in the area
Why is commercial farming a threat?
Too many crops are produced for the people to eat
Fair Trade has made the crops too expensive for the locals
Malaysia is the largest exporter of palm oil, increasing amounts of TRF are converted into plantations as plantation owners receive 10 year tax incentives.
Too many pesticides enter water ways polluting rivers
Why is population pressure a threat to the TRF?
People in overcrowded cities where encouraged by the government to move to the countryside
This movement of people is called transmigration and occurred between 1950s and 1980s
Too many people seek work as farmers
This movement of people led to the felling of 15,000 hectares of TRF for new communities and plantations
What are the main impacts of deforestation in Malaysia?
Soil Erosion
More wood and TRF products
Economic development and climate change
Loss of Biodiversity
What are the impacts of soil erosion?
People will have less opportunities to grown their own veg and crops
Soil takes thousands of years to be replaced
Deforestation means soil can be easily removed and eroded away
Soil leads to a loss of biodiversity.
What is the impact of a loss in biodiversity?
Loss of TRF will lead to loss of biodiversity
Many undiscovered plants could have medicinal purposes, a reduction will lead to less discoveries and cures.
Deforestation leads to exposed hillslopes, exposing soil to erosion by rain and wind - this leads to loss in biodiversity as plants die.
Deforestation destroys habitats on the ground and in the trees.
Which of these are classed as economic gains to deforestation
Pollution of water sources and an increasingly dry climate may result in water shortages.
Improved infrastructure opens up new areas of industrial development and tourism
Rising temperatures could devastate some forms of farming such as growing tea, fruit and flowers.
Companies will pay taxes to the government which can be used to improve public services such as education and water supply.
Which of these are classed as economic losses to deforestation
Rising temperatures could devastate some forms of farming such as growing fruit, tea and flowers.
The number of tourists attracted by rainforests could decrease.
Hydro-electric power will produce cheap and plentiful energy
Products such as palm oil and rubber provide raw materials for processing industries.
How does deforestation contribute to climate change?
Deforestation impacts local and global climates
Trees absorb CO2 and emit oxygen, deforestation reduces this process.
The process of evaporation uses up heat and cools the air, if trees are cut down, this cooling ceases and temperatures increase.
Trees give off moisture by the process of transpiration, deforestation reduces the moisture in the air resulting in a drier climate.
