A

social
- famine from crop failure/ political conflict - Ireland had the potatoe famine in 1845
- undernutrition
- protests

economic
- with a limited amount of food the price increases - causes inequality

environmental - increased pressure leads to:
- overgrazing
- deforestation

Q

CASE STUDY - jamalpur background info

A
  • north bangladesh
  • subsistence farmers ( only grow enough food for themselves )
  • Rice and wheat farming most common
  • The charity, Practical Action, has been supporting farmers in the region by introducing a new type of farming called rice-fish culture.
18
Q

CASE STUDY - jamalpur why do they have rice-fish cultivation

A
  • sustainable approach to increasing food supplies
  • does not involve any artificial fertiliser or pesticide.
  • does not require expensive equipment or external expertise.
  • It is also not harmful to the environment.
19
Q

CASE STUDY - jamalpur how does rice fish cultivation work

A
  • PA help farmers find a field that wont wash away in flood
  • dike built around edge of field
  • ditch dug for fish to live i dry season
  • farmer plants rice in rows and fills 50% of ditch with water
  • water purified with lime
  • rice gets harvested 4/5 months later and fish are collected
20
Q

  • largest concentration of greenhouses globally from large buisnesses and farmers eg bying out of season food
  • gets $1.5 bill a year
21
Q

CASE STUDY - almeria why has it developed

A
  • diets change more ppl want fruit
  • better transport on planes ect - cheaper
  • cheap labour
22
Q

CASE STUDY - almeria advantages and disadvantages of large scale agriculture development

A

pros
- irrigation and hydroponics - less water used
- warm temps - low energy costs
- lots of jobs
- fruit and beg all year round

cons
- plastics dumped in sea
- immigrants work illegally so bad working condiitons
- ecosystems destroyed bc large areas covered in plastic
- aquifers dying up bc too much water being used for greenhouses

23
Q

list of ways for sustainable food production

A
  • organic farming
  • permaculture
  • urban farming
  • fish sources
  • local and seasonal produce
  • reducing food waste
24
Q

list of ways to increase food supply

A
  • irrigation
  • aeroponics and hydroponics
  • green revolution
  • biotechnology
25
Q

list of ways to tackle food import problems

A
  • agribusiness
  • organic crops
  • fair trade
26
Q

uk high value foods

A
  • exotic fruits

  • water is also needed to make clothes an poducts
29
Q

what happens if people cant get enough energy

A
  • we need it for industry and transport
  • makes a country wealthier by supplying jobs by developing their industries
  • lifestyle in an hic is depended upon lots of energy
  • without electricty ppl may use other more pollutung resources eg kerosene stoves release harmful fumes
  • electricyt can power pumps for wells for sanitised water
30
Q

the global food consumption supply in HIC, NEES,LICS

A

HIC
- very high bc they can afford to import
NEE
- increasing rapidly because industry developing fast and pop and wealth also increasing fast
LIC
- low bc they cant afford. this is bc they lack the resources and cant afford to import or they get exploited by the hics

31
Q

what increases our carbon foot print

A
  • growing, processing and packaging
  • food miles - transporting food from where its grown to where its consumed
32
Q

how has farming become industrialised

A

agribusiness - large scale industrial famring where all the processes are controlled by large firms
- lots more harmful chemicals now used
- much larger scale
- much less workers now due to technology

33
Q

where is there surplus and deficit in rainfall in uk

A

surplus - north and west - low pop density
deficit - south east and midlands - high pop density

34
Q

why is water demand increasing

A
  • water used in house holds increased by 70% bc more appliances eg dishwashers
  • population increase
  • pop density changing - more homes in south east where there is already a deficit
35
Q

how does the water become polluted

A
  • nitrates and phosphates from crop fertlilisers washed into rivers and groundwater
  • pollutants from vehicles washed into water sources through runoff whren it rains
  • chemicals and oils spills from factories pollute riverss
36
Q

where does water in uk come froms to improve water quality

A
  • better drainage systems
  • regulations about the types of fertlisers and pesticides used
37
Q

issues with water transfer (moving water from surplus to deficit areas)

A
  • dams and aqeduts are expensive to build - birmingham prohect £300 mil
  • affect wildlife eg fish. migration can be disrupted by dams etc
  • political issues
38
Q

hows the uks energy mix changed

A
  • used to be 91% coal and oil - v bad for environment
  • then found gas reserve under north seas in 1980 so 22% was then gas
  • now more renewable energy so 19% renewable
  • wind and biofuels and biggest sources of renewable energy in the uk
39
Q

economic issues with energy sources

A
  • gettings fossil fuels ££££££
  • north sea oil is £££££ to produce - not worth it
  • cost to the consumer for nuclear and renewable energy is high
  • money needed to research new types of energy eg shale gas
  • domestic sources dont reach uk demand so we have to import
40
Q

environmental issues with energy sources

A
  • fossile fuels - cc
  • fracking - pollutes groundwater and mini earthquakes
  • oil spills or nuclear accidents - toxic chemicals
  • ## wind farms and tidal projects - drsrupt natural ecosystem
