Hot Deserts

-Kalahari Desert

- covers an area of about 260,000 Km2. It covers most of Botswana and parts of zimbabwe, Namibia and South Africa.

- Only about 200mm of rain per year meanting that there is one permenant river and droughts are a problem.

- Sparsley populated but there are some native people some of who still hunt and gather their food.

-  Farming is a big industry in the Kalahari for example, in 1998 there were  2.3 million cattle in BNostwana.

- There is alot of mining in the area. These include coal, diamond, gold, copper, nickel and uranium mines.

-Negative impacts

- Overgrazing of the land causes soil erosion, and irigation has depleted groundwater supplies.

- Fences put up by farmers have blocked migration routes causing animals to die from starvation.

- Mining and farming have caused natives to be forced off their land.

- Mining is depleting groundwater supplies.

11 of 51

Management strategies in the Kalahari

- Some places are trying to conserve water 

- The water supply is being increaced by building dams and drilling more             boreholes.

- Several game reservs have been created to give the natives and the animals    somewhere to live. 

- Some agricultuiral fences have been removed to allow for anomal migration.

12 of 51

The Mojave Desert

- Covers over 57,000 Km2. It is spread over paarts of California, Nevada, Utah and Arizona

- There are many tourist destinations including Las Vegas and Death Valley.

- There were many mines but now there are only a few borax mines.

13 of 51

The Mojave Desert


- The rapid population growth has depleted the water resources

- Farming uses alot of water resources and causes soil erosion

- Tourists deplete water resources, drop litter, damage plants and cause soil erosion


- Water conservation schemes which give vouchers to buy water efficient appliances and encourage people to change their behaviour eg:  changing lawns for plants

- There are 4 national parks, Death Valley, Ioshua Tree, Zion and The Grand Canyon - species are protected and there are strict rules on mining on and on use of the natural resources.

- There are designated roads for off road vehicles to stop them from damaging plant life

- Some hotels in Las Vegas are trying to conserve water eg: The Mirage uses drip irrigation to water lawns.  It is more sustainable.

Ageing Populations - UK

People living longer due to advances in medicine and improving living standards

-       From 1980 – 2006 life expectancy rose 2.6 years for women and 6.4 for men

-       Life expectancy currently 81.5 for women and 77.2 for men

-       Many babies born in 1940s and 1960s – Baby Booms

-       Now the 1940s babies are retiring creating a pensioner boom

-       Since 1970s birth rate fallen – therefore fewer younger people & the population is growing older

-       More elderly are living in poverty

-       Working population not big enough to pay for a sufficient pension

-       Despite low State Pension, gvt struggles to pay it – taxes insufficient to cover it and the more retirees there are, the more of a problem it becomes

-       Health Service under pressure – older people need more medical care eg average stay in hospital in 2005 was 8 nights but 13 for over 75s

31 of 51

Ageing Populations - Coping Strategies

UK Gvt raising retirement age – by 2046 will be 68 for all

-       Leads to more paying tax and fewer claiming pensions

-       80% of EU immigrants to UK are 34 or under

-       Encouraging women to have children

-       Encourage people to take out private pensions

On an island on Xingu River in Brazilian state of Para

Owned and operated by co-op of 6 local tribes

Lodge has 15 room and offer activities, fishing, canoeing, wildlife viewing and forest walks


Lodge buit from local materials such as straw and wood that were found on the ground so no trees were felled.

Also doesn't spoil scenery

Uses solar power to run lights - better for environment

Locally produced food served in lodge

48 of 51



Lodge owned by indiginous tribes rather than big foreign companies so income goes to local economy.

Locally produced food is bought from locals so money goes into local economy


Lodge creates jobs

People in nearby villages encouraged to visit the lodge to sell crafts and perform traditional songs and dances. Gives income and preserves culture.

Profits from lodge provide health care and eduction for local people from tribes

Development is sustainable because money to do it is generated without damaging the environment.

Continent on Earth's south pole, covers 14 millions KmSq, 98% covered with ice.

Number of tourists is rising, e.g. 7,413 in 1996-97 season but 46,000 in 2007-8 season.

Tourist attracted by stunning scenery, icebergs, and wildlife - penguins, whales.


Tourist can trample plants, disturb wildlife, drop litter etc

Fears tourists could introduce non-native species or diseases

Spillage of fuel from ships is a concern - can kill molluscs,( e.g. mussels) and fish (e.g. fish) also impacts birtd that feed on the fish - (e.g. penguins)


Antarctic Treaty - came into force in 1961; 47 countries have signed it; designed to protect area and wildlife.

Only ships with fewer than 500 passangers are allowed and only 100 ashore at a time

50 of 51


International Assocation of Antarctica Tour Operations (IAATO) has sep voluntary code of conduct

which most stick to:

1. Specially protected areas off limits to tourists

2. Wildlife not to be disturbed when observed

3. Nothing to be left by tourists, no smoking during shore landings

4. Tourists must stay with group which must have qualified guide...prevents entering no go areas or disturbing wildlife.

5. Tourists not to walk on fragile plant life

6. Sewage treated biologically and other waste stored on ship
