Increased by 85% in

14. Malaysia Case Study Threats to the rainforest:
1) Logging- clear felling from 1980 was common which led to large areas being cleared. Selective logging now occurs. In 2003 a local penan community was impacted and those that protested were imprisoned.

15. Malaysia Case Study Threats to the rainforest:
2) Energy- The $2bm Bakun Dam project in Sarawak (completed 2012) resulted in flooding of hectares of forest. 230km2 of forest to be cut down for it.

16. Malaysia Case Study Threats to the rainforest:
3) Mining- tin and smelting the dominant form of mining in the area. Areas clearer for roads. Drilling for gas and oil has started in Borneo.

17. Malaysia Case Study Threats to the rainforest:
4) Commercial plantations- major producer of palm oil and rubber. In early 20th century forest was cleared for the rubber plantations.
Today it is known for palm oil, in 1970 vegetation changed to palm oil plantations.

18. Exploiting The Forest
Watch:

19. National Forest Policy
‘Selective Management System’.

23. Temperate Climate http://www.youtube.com/watch?v=swEZ2vnnre4
The Biome in the UK is a temperate climate.
Rainfall is distributed evenly through out the year, summers are warm but not too dry, winters are cool but not too cold.
There is a long growing season lasting up to 7 months.

28. Epping Forest 70% of Epping forest is deciduous.
City of London Corporation is in charge of maintaining the forest.
Used for recreation such as riding, mountain biking, golf, football.

29. Pollarding
What is pollarding?
How does it differ from coppicing?

30. Desert Climate
A desert is an area that receive less than 250mm of rainfall.
Found in dry continental interiors between 30N and 30S
Constant belt of high pressure which means no clouds.
Soils are sandy with little organic matter due to little vegetation.

31. Case Study In A MEDC Australian Outback Tourism:
BBC top 50 things to do is to watch the sunset at Uluru.
400,000 visitors in 2005
Can buy aboriginal arts and crafts
BUT
Can exploit the aboriginal culture
Learn little about the culture and history- just tick it off the list.

32. Case Study In A MEDC Australian Outback Hunting and gathering:
Finding edible plants and animals.
They create conditions in which grubs can live and breed.
Build dams along the river to catch fish.
Use fire to drive out animals for hunting.
The area has now grown a ‘native food’ industry based on traditional aboriginal knowledge of what is edible.

33. Case Study In A MEDC Australian Outback Mining:
Most people are involved in this.
Some of the worlds largest reserves of iron ore, silver and gems.
Coober Pedy in S. Australia is the opal capital of the world. (70%)
Most iron ore sent to China
Huge ships are loaded up with 250,000 tonnes of iron ore.
The demand meant prices rose by 70%

34. Case Study In A MEDC Australian Outback Managing the issues: Farming:
Farmers have to use boreholes which may not last.
Recent drought is putting pressure on water stores.
Tourism:
The new Uluru Aboriginal culture centre educates visitors about the history and culture.
Leads outback walks to inform visitors about bush food as well as cultural sites.
30 Aboriginal people work there and the admission fees go to the Anagu community.

35. Case Study In A LEDC
Sahara Desert, Africa

36. Case Study In A LEDC Sahara Desert, Africa Energy:
Difficult to find oil and gas reserves.
In Algeria they have found oil and half of their income comes from there.
Workers travel in and out via plane.
40,000 work at Hassi Messaoud.
Pipelines have to carry it hundreds of km to the north African coast.
Sahara Desert, Africa

37. Case Study In A LEDC Sahara Desert, Africa Overcoming Energy issues:
Within Algeria work has begun to create the first solar power plant in the Sahara desert.
The aim is to export solar power to Europe through cables under the Mediterranean sea.
Sahara Desert, Africa

38. Case Study In A LEDC Sahara Desert, Africa Farming and Irrigation:
Egypt has a soaring population which has increased from 20 million to 79 million in 25 years.
Most live on the heavily irrigated Nile Valley. This irrigated land means that farmers can grow more food, both to feed the growing population and for export.
13% Egypt's GDP comes from farming and employs 32% of its labour force.
Sahara Desert, Africa

39. Case Study In A LEDC Sahara Desert, Africa
Overcoming Farming and Irrigation issues:
Plan to irrigate more land away from the Nile Valley.
The Toshka Project will cost $70 billion.
Will use pumps and canals to transfer water from Lake Nasser into the Western Desert.
Increase irrigated land area by 30%
Enable high value crops such as olives, citrus fruits and vegetables.
Promote tourism
Provide food, electricity and jobs for 16 million Egyptians in new owns in the desert.
Sahara Desert, Africa

40. Case Study In A LEDC Sahara Desert, Africa
Overcoming Farming and Irrigation issues:
Trying to stop desertification:
Restrict the number of farm animals
Growing crops as well as grazing animals
Planting more trees to protect the soil from wind and rain
Building earth dams to collect and store water which can be used to water plants.
