people in the area may no longer be able to feed themselves because land is too infertile
up to 10million people may be forced to migrate and become environmental refugees

28
Q

How are water engineers a stakeholder in the Aral sea?

A

inspection revealed many irrigation canals were poorly built allowing water to leak or evaporate
Main Karakum canal largest in central Asia allows 30-75% of water to go to waste

29
Q

What has Kazakhstan secured since 2007?

A

massive world bank loans to save northern part of Aral sea #very ambitious project to reverse worlds worst environmental disaster

30
Q

how much is aquaculture growing per year?

A

10%

31
Q

How much does aquaculture account for all fish catches?

A

1/3

32
Q

Is aquaculture sustauinable?

A

at face value yes
but environmental issues (pollution, diseases, food safety and public health)

33
Q

What is aquaculture?

A

farming of fish, crustaceans, molluscs, aquatic plants and other organisms in controlled conditions at coastal edge

34
Q

What is removed to make way for fisheries?

A

mangroves often removed

35
Q

Why are mangroves important?

A

provide excellent storm protection
in hurricane they act as breakwater for storm surge and reduce surge impact on land
good for coral reefs reduce sedimentation on coral by slowing water due to complex roots

36
Q

what is a good example of the importance of mangroves?

A

during 2004 tsunami areas with mangrove along coastline saw less damage

37
Q

when does industry use water?

A

for both cooling and as part of manufacturing process

38
Q

what is the problem with water and industry?

A

often cause pollution
China water pollution globalisation
Coca cola over abstraction

39
Q

How much water used in industry is used for HEP or cooling power stations?

A

50%

40
Q

what is the problem with cooling water from power stations?

A

is returned to river unchanged but slightly warmer which could impact ecosystems

41
Q

what does industry include a lot of? (water usage)

A

virtual water- hidden flow of water in food and other commodities

42
Q

What are the conditions like in the Middle East?(climate)

A

Naturally arid region with irregular rainfall
Much of region considered desert

43
Q

The river Jordan which starts in Isreal, Syria and Jordan

45
Q

What is the security/ access problem with the river Jordan?

A

It flows though many countries

46
Q

Why is water access and flow made more difficult in the Middle East?

A

Due to political concerns between neighbouring countries

47
Q

What is the first ‘hit’ that affects the river Jordan?

A

Near the source in Israel the food production area of the Middle East

48
Q

Why is Israel seen as the bread basket and fruit bowl of the Middle East?

A

As area was once desert but irrigation has turned it into farmland

49
Q

What sort of fruits do they grow in Israel?

A

Mangos
Avocados
Bananas

50
Q

What is the problem with the crops grown in Israel?

A

More suited to tropical climates with greater rainfalls meaning they are thirsty plants

51
Q

Why do they grow these water intensive plants in Israel?

A

The fruits yield 5x more money than olives per kg

52
Q

What are the two sides of the crops grown in Israel?

A

Farmers claim it is sustainable as it increases their wealth
Environmentalists see it as an unnecessary drain on the river

53
Q

What is the second hit on the river Jordan?

A

Creation of the Galilee reservoir in Israel which stores water for most of the population

54
Q

Hat is another use besides water storage of the Galilee reservoir?

A

Used for recreation bank contains resorts and golf courses

55
Q

What is the 3rd hit to the river Jordan? (Sewage)

A

As the river enters Jordan raw sewage and brine is released into the river as it heads through towns and farmland

56
Q

What happens to the use of the river Jordan after the third hit?

A

River too polluted to be used for irrigation

57
Q

What do farmer have to do when they can’t use the river Jordan for irrigation?

A

Have to divert water form elsewhere for their crops

58
Q

What is the issue with farmers diverting water form other areas for irrigation? (Middle East)

A

Bridges built by romans that were very high to get over river now useless due to significantly reduced flow
reduces water availability for other areas as well

59
Q

What is the final stage of the river Jordan?

A

Enters the Dead Sea as polluted trickle which isnt enough to maintain water levels of the Dead Sea causing it too drop 1m a year

60
Q

What has the lowering of the Dead Sea caused?

A

Caused pressure to drop in nearby rocks and caused geological instability
Sink holes formed meaning local campsites and tourist activities had to close affecting economy in the area

61
Q

How is the Yarmouk affecting the river Jordan?

A

The river Yarmouk form Syria usually replenishes the river Jordan but is being over abstracted for irrigation

62
Q

What was the effect on Israel due to over abstraction of river Yarmouk?

A

HEP plant built in the 1970’s had to be shut down as there wasn’t enough flow to produce energy

63
Q

What is the overall problem affecting the Middle East and their water security?

A

Inability for neighbouring countries to work together has affected. Them environmentally (no HEP, irrigation or fishing) and economically (no HEP for energy or campsites bordering river)
Farmers have to import water
Social- religiously historic river no longer safe for pilgrims to bathe in
