1
Q

why is demand for food increasing

A

as population grows, there are more mouths to feed- demand for more food

as wealth increases, there’s a higher demand for a range of ingredients and high quality produce

increased demand from LIC’s as imports from LIC’s are cheaper- cheaper cost of production

Q

positives of importing food from LICs

A

-cheaper cost due to lower labour wages and cheaper cost of production

-can get unseasonal produce- range of ingredients

-job creation- multiplier effect

Q

negatives of importing food from LIC’s

A

-increased food miles- increased carbon footprint, more CO2 emissions

-workers have less land and water to grow own food

-poor working conditions, low wages- no protection against pesticides, causes health issues e.g cancer

Q

how much of UK’s fruit is imported and why

A

89%
UK climate does not promote exotic crop growth

little sun, lack of humid climate

Q

how does increasing demand for imports affect food miles/ carbon footprint

A

as demand increases, imports increase
more planes import products
:) planes are quick
:) can transport large amount of produce

:( planes release CO2- increases CO2 in atmosphere, increased carbon footprint= enhanced greenhouse, global warming

Q

how can you locally source food to reduce food miles

A

grow own food- veg and fruit patches in gardens

farmers markets- reduces imports from abroad, supports local farmers

buy seasonal produce- e.g only buy strawberries in summer where yield is greatest

Q

positives of organic produce

A

no pesticides- does not affect other animals, no health issues, no pollution of rivers

natural fertilisers E.g compost- has minerals which promotes crop growth, no synthetic chemicals

natural predators E.g ladybugs

Q

negatives of organic produce

A

natural predators don’t kill the whole population of pests- more pests means smaller yield

natural fertilisers take longer- slower crop growth

positives of agribusiness

A

food security- larger crop yield

cheaper food prices due to a larger crop yield

expand farms- more land- more crops

advanced technology

fertilisers- promote plant growth

Q

how has demand for water increased in UK

A

Increased by 70% since 1985
As wealth increases, demand increases:

-more showers/baths
-water intensive machines E.g dishwashers
-water in greenhouses to grow unseasonal produce

Q

what is water deficit

A

low supply of water
E.g south east UK, london

little precipitation, high population- demand for water is greater than supply

16
Q

what is water surplus

A

high supply of water
E.g West Wales

high precipitation, low population- supply is greater than demand

17
Q

define water stress

A

when water availability does not meet the needs of people or is of low quality

18
Q

what is a water transfer scheme

A

transferring water using pipes from an area of water surplus to an area of water deficit
E.g west wales to London

19
Q

positives of water transfer scheme

A

less restrictions in water scarce areas

construction of dams creates jobs- multiplier effect

dams- recreational activities, tourists increase, increased income

reservoirs- new aquatic habitats

20
Q

negatives of water transfer scheme

A

dams flood natural habitats

disrupts fish migration

expensive to build

dams displace locals

21
Q

causes of water pollution

A

oil leaks
runoff from pesticides and fertilisers
sewage

22
Q

how do pesticides cause water pollution

A

poisons rivers

harms aquatic life, fish- people become sick due to eating poisoned fish

less fish- less income to fishermen

23
Q

how do fertilisers cause water pollution

A

heavy rainfall causes runoff
fertilisers contain nitrates- promotes plant growth, soluble in water

eutrophication- algal bloom, plants die as there is no sun reaching them,
decomposers respire and lower oxygen content- fish die

24
Q

management strategies to prevent water pollution

A

education campaigns- encourage people to conserve water, not throw rubbish into rivers

eco-friendly features on machines- saves water

pollution traps- catch waste

limit use of pesticides and fertilisers- reduces runoff

25
Q

how has demand for energy increased in UK

A

as wealth increases, demand increases
higher demand for fuel for cars, electricity for homes,

as population increases, demand increases- more people need more energy

26
Q

positives of fossil fuels

A

:) relatively cheap
:) job creation in power plants
:) produces lots of energy

27
Q

negatives of fossil fuels

A

:( release CO2- increased carbon emissions- global warming
:( non-renewable
:( release sulfur dioxides- react with water to form acid rain

28
Q

positives of nuclear energy

A

:) no fossil fuels
:) no CO2 emissions
:) job creation
:) reliable

29
Q

negatives of nuclear energy

A

:( radioactive waste- hard, expensive to clean, damages ecosystems
:( expensive

30
Q

positives of renewables (wind)

A

:) no carbon emissions
:) renewable, sustainable
:) no fossil fuels

31
Q

negatives of renewables

A

expensive
solar- unreliable, only works with light
wind- danger to birds, noise pollution, ruins views, decline in tourism

32
Q

management strategies to conserve energy

A

encourage renewables

raise energy prices so people use less (some people cannot afford)

put a fee on heavy polluting vehicles

low energy features on machines

33
Q

what is fracking

A

extracting natural gas, oil, geothermal energy from the earth

34
Q

positives of fracking

A

:) low energy prices
:) less carbon emissions
:) no fossil fuels
:) domestic source- reduces imports

35
Q

negatives of fracking

A

:( earthquakes
:( releases methane- enhanced greenhouse effect
:( pollutes groundwater

36
Q

coal imports

A

coal is imported to UK
it is deep in mines underground- hard to access

increased coal imports- increased carbon footprint- enhanced greenhouse effect
