What is the significance of energy on economic and social well-being?

A
  • need energy for industry and transport
  • energy in industry allows a country to develop
  • people may use other methods of fuel without electricity causing negative environmental impacts
  • can be needed to power wells and water sanitation
  • lack of energy means people can’t travel for increased QoL

Q

How is the global supply and consumption of resources uneven?

A

Some counties don’t have there own energy reserves
Some countries don’t have a climate suitable for food production
Consumption of resources depends on a countries wealth and availability
Consumption is increasing in NEE - China
Consumption is low in LICs because they can’t afford to import of export there own resources

Q

Why is the uks carbon footprint going as a result of food?

A

Growing, processing and packaging produces co2
Transporting food also produces CO2

22
Q

How does pollution effect water availability?

A

Increasing amounts of waste and growing amount of chemicals have led to higher pollution. Some water sources are often used as open sewers leading to waterborne disease

23
Q

How does poverty effect water availability?

A

Poorer communities lack mains water supply

24
Q

How does limited infrastructure effect water availability?

A

Poorer countries lack infrastructure for transporting water

25
Q

How does geology effect water availability?

A

Infiltration of water through permeable rock builds up ground water supplies

26
Q

How does over abstraction effect water availability?

A

Pumping water out of ground faster than it’s replaced.
This can lower water tables and mean rivers aren’t fed by springs in the dry season

27
Q

What is the impact of water insecurity?

A

Waterborne disease - little to no sanitation causes disease
Food production - agriculture uses 70% of water globally drier seasons cause impacts on food production
Industrial output - growth of manufacturing is increasing demand
Water conflict - water sources cross national and political borders

28
Q

What is an example of how water insecurity has caused disease?

A

In the River Ganges - India
Over 1 billion litres of sewage enter each day.
Runoff of fertilisers in another source of pollution
Pollution has become so serious it has lead to diseases

29
Q

What is an example of how food production can be effected by water insecurity?

A

In Egypt shortage of water is causing food insecurity. The Nile’s flow is expected to drop 90% and 80% of it is used for agriculture. Therefore Egypt has to import around 60% of their food

30
Q

How is industrial output being effected by water insecurity?

A

Chinas industry uses 30% of available water . Water shortages mean some factories have to temporarily close and chinas industry relies on coal resources which use 20% of chinas water

31
Q

How is water conflict impacted by water security?

A

The river Jordan flows through Jordan and Isreal. Isreal takes water from the Sea of Galilee. Palestine has no acces to water except depleting groundwater supplies so Isreal can control what water gets sent to Palestine causing conflicts

32
Q

Outline the ways to increase water supply

A

Diverting supplies and increasing storage
Dams and reservoirs
Water transfers
desalination

33
Q

How can diverting supplies and increasing storage increase water supply?

A

Water supplies can be artificially diverted and stored for use over long periods
Surface water evaporates really quickly
Water can be stored in aquifers underground

34
Q

How can dams and reservoirs increase water supply?

A

Damns control water flow in rivers but storing water in reservoirs
Rack all can be collected and stored and released gradually
Dams can cause environmental and land issues

35
Q

How can water transfer increase water supply?

A

Aim to redistribute water from areas of surplus to areas of deficit.
Often elaborate of canals and pipelines

36
Q

How can desalination increase water supply?

A

Inolves removing salt from sea water,
Very expsinve as it requires lots of energy
Only used in areas where there are few alternatives such as in UAE

37
Q

What is the name of an example of a large scale water transfer scheme?

A

Lesotho highland water project

38
Q

What is the Lesotho highland water project?

A

1 HEP plant
200km of tunnels

39
Q

What are the advantages of the Lesotho highland water project for Lesotho?

A

Provides 75% of its gdp
Income improves standard of living
Supplies HEP
Water will reach 90% of population

40
Q

What are the advantages of the Lesotho highland water project for SA?

A

Provides water during low rainfall periods
Fresh water is rescuing acidity is reducing water pollution

41
Q

What are the disadvantages of the Lesotho highland water project for Lesotho?

A

30k people were displaced for land
Destruction of wetland ecosystem
Corruption prevents money reaching those effected
Reduce agri land for 70 villages

42
Q

What are the disadvantages of the Lesotho highland water project for SA?

A

Cost likely to reach 4 Billion
40% of water lost to leakage
Corruption plagued project
Increased water tarrifs are too high for the poor

43
Q

What is sustainable water supply?

A

Sustainable approaches to managing water supply focus on careful management of resources and the need to reduce water waste and excessive demand.

44
Q

Outline the ways of sustainable water supply

A

Water conservation
Groundwater management
Recycling
Grey water

45
Q

How does water conservation help water supply?

A

Reducing leakages - 25% of global water is lost
Monitoring illegal connections
Improves awareness on need for water saving
Prevent pollution

46
Q

How can groundwater management increase water supply?

A

Managing water stored underground to maintain quantity and quality
Balances water abstraction and water gain

47
Q

How can water recycling increase water supply?

A

Reusing treated domestic or industrial waste water
Large quantities of recycled water are used for cooling in industry
Reuse for fish farming and agriculture
Nuclear power plants

48
Q

How can using grey water increase water supply?

A

Grey water is taken from bathroom sinks, baths and showers.
It may contain traces of dirt and grease and cleaning products
But if used within 24hr contains valuable fertilisers for plants

49
Q

What is the name of the example of a local scheme in an LIC?

A

Wakel River Basin Project

50
Q

Where is the wakel river basin project?

A

In rajasthan india.
Driest and poorest part of India
Summer temps can reach 50 degrees
Rainfall less than 250mm per year

51
Q

What are the issues that caused the wakel river basin project?

A

Water management is poor
Over abstraction from unregulated pumps have lowered water tables

52
Q

What are the two main aims of the wakel river basin project?

A

Increase water supply and storage using appropriate local solutions
Raise awareness in local communities of the need for Effective water management.

53
Q

What are the three ways of increasing water supply in the wakel river basin project?

A

Taankas - underground storage systems to collect surface water before evaporation.
Johed - small earth dams to capture rainwater to help raise water tables
Pats - irrigation channels to transfer water to the fields

54
Q

How is the wakel river basin project increasing local awareness?

A

A cycle campaign was done to spread the message about water conservation
