Q

What is an economic issue in exploiting energy resources? Double develop

A

Fossil fuels Expensive
Nuclear and renewable energy expensive
U.K. doesn’t produce enough energy to be self sufficient soo pays other countries to export-need to take care if international relations-anything anywhere will affect U.K.-dependence

Q

Why is water demand in U.K. increasing?

A

People have more appliances tias use loads of water
U.K. population is predicted to increase by over 6 million by 2040
People are moving to east and south-increased rush if becoming water deficit

Q

How much water is lost every year to leaks?

A

20% of all water before point of use
Millions of litres

22
Q

What are two limitations of water transfer schemes. Double Develop

A

People might be displaced
Loss of Wildlife habitats-disrupt flow of rivers
Cost of maintenance-machinery + building materials-contribute to climate change

23
Q

What are some strategies to manage water quality and pollution?

A

Moniter river water quality
Legislation
Tree planting

24
Q

What are some issues with water pollution?

A

Fertilisers/sewage-eutrophication-algae out of control-reduce oxygen levels-dead zones
Chemicals/industry (heavy metals)-bioaccumulating-damage to food web

25
What does water security mean?
Having enough clean water to sustain well being, good health and economic development in a country
26
What does water insecurity mean?
Not having enough clean water, occurs when there isn’t a reliable, sustainable source
27
What are the global patterns for water surplus and deficit?
Overall, the distribution is uneven. An area with water surplus is the Amazon basin. An area with water deficit is the Great Sandy Desert
28
What factors increase demand for water?
-Population-demand for food-water needed for irrigation to increase yield -Economic development-increase affluence-but more consumer goods increasing industry-more water used to manufacture
29
What are a physical factor affecting water availability?
Geology-if impermeable rock runs off into rivers and lakes and easy to access. If permeable it’s absorbed into ground making it harder to get to Climate-in hotter places, more evaporation, dry areas being drier, increasing risk of droughts
30
What are a socio-economic factor affecting water availability?
Polluted water sources-industrial waste being dumped straight into rivers Over-abstraction more water is removed than can be naturally replaced Limited infrastructure, sewage getting into water sources and contamination supplies-eutrophication-cholera typhoid
31
What is an impact of water insecurity? Double develop
Waterborne disease and water pollution-cholera, ill health-reduced work, reduced economic input Food production-yields go down, famine, displaced population Industrial output-not enough energy, unreliable electricity, less goods produced, less tax from export, less government revenue Potential for conflict-grand Ethiopian Dam on blue Nile “water war” Egypt vs Ethiopia
32
What are the 4 ways to increase supply?
Dams and reservoirs Diverting supplies Water transfer Desalination
33
What are some advantages and disadvantages of building dams?
Advantages: Store water during high rainfall periods to use during low rainfall periods Disadvantages: Expensive Displaced population Disrupts fish migration Long building time More weeds, less oxygen, dead zones
34
What are some advantages and disadvantages of using diverting supplies?
Advantages: Irrigate farmland Disadvantages Largemouth bass and catfish at risk Disrupt fish migration and breeding
35
What are some advantages and disadvantages of desalination?
Advantage: Lots of seawater available Reduce pressure on other success of water Could meet demand Disadvantage: Expensive Used lots of energy High CO2 emissions Need seawater
36
South-north water transfer scheme What % of Beijing’s water comes from the south?
70%
37
South-north water transfer scheme What is a social advantage of the scheme? Double develop
Provide clean water for 500 million people in north-east “thirsty area” secure water supply-less risk of contaminated water-cholera, waterborne diseases
38
South-north water transfer scheme What is a economical advantage of the scheme? Double develop
Over-abstraction is no longer happening-fewer houses collapse-less damage to infrastructure-
39
South-north water transfer scheme What is a social disadvantage of the scheme? Double develop.
Droughts are becoming common in the south. Might not be enough water for 30 million people to drink or irrigate land -less crop yield-risk of food shortages-increased cost of food
40
South-north water transfer scheme What is a economical disadvantage of the scheme? Double develop.
Cost $62 billion of government money- less money spent on other social issues eg school and hospitals Over 3500 businesses were forced to close and relocate-lose money-not production goods-lose source of income “spiral of decline” negative multiplier effect
41
Using water sustainably What are some features of water conservation?
Using less water Fixing leaks in reservoirs, pipes and taps Using appliances that use less water (e.g dual flush toilets) -water meters
42
Using water sustainably What are some advantages/disadvantages of water conservation?
+ reduced amount needed to be abstracted or treated for repeated use -can be difficult to get people to follow the rules
43
Using water sustainably What are some features of groundwater management?
30% of global freshwater Cheap clean water Over-abstraction- subsidence-let the water table recharge
44
Using water sustainably What are some advantages/disadvantages of groundwater management?
+ reduce contamination and over abstraction means aquifers can recharge and the supply remains stable -aquifers can be very large and when countries share it’s hard to agree to a fair amount everyone can abstract
45
Using water sustainably What are some features of water recycling?
Using water that has already been used Filtered and used for irrigation, industry, toilet flushing etc but can be made safe to drink Reduces pressure from groundwater stores
46
Using water sustainably What are some advantages/disadvantages of water recycling?
+ can be used again and again, reducing demand - pumping to and from homes and businesses can be expensive and use loads of energy
47
Using water sustainably What are some features of ‘grey wateri’?
Domestic use Reuse for things like flushing toilets (don’t have to be clean) Collected from washing machines, showers and sinks
48
Using water sustainably What are some advantages/disadvantages of ‘grey wateri’?
+ re-use no energy is used pumping it around the country - can be expensive to set up water storage in homes to catch water from showers and dishwashers
49
Investing sustainable water supply (Kenya) What are some pros and cons of sand dams
+ cheap to build, use local materials, clean water supply, water for irrigation - less water lost my evaporation (stored underground) Not enough water for dry seasons Fish dies-affects local ecosystem
50
How does a sand dam work?
A low, concrete dam is built across a river. During the rainy season, water and sand flows in the river. Sand and water gets trapped behind the dam. The sand prevents the water from evaporating in the dry season. When the river stops flowing water can be extracted. This can be done by digging Well, pumping water out to a trap or simply digging holes in the sand to dig it out.
