resource management

Question 1

what are the 3 resources everyone needs

Answer 1

• water
• food
• energy

Question 2

what does malnourished mean?

Answer 2

• when people dont get enough nutirents this can then lead to deficiencys which can prohibit development

Question 3

what does undernourished mean?

Answer 3

• when people don’t get enough food of any kind

Question 4

what happens due to a lack of sanitation?

Answer 4

• water sources get polluted by raw sewage

Question 5

impacts of waterbourne diseases?

Answer 5

• diseases such as cholera and typhoid kill many people a year

Question 6

why is water needed?

Answer 6

• water is needed to produce food, clothes and other product so it impacts ppls lifestyles

Question 7

whats energy needed for?

Answer 7

• indusrty and transport & use homes
• allows countires to develop indusrty, creating jobs and wealth

Question 8

how does HICs & LICs energy supply differ?

Answer 8

• HICs depend on a large, stable supply of elec
• LICs liitle/no electricity = use other resources to make fuel e.g burning wood = deforestation & kerosene stoves can release harmful fumes

Question 9

what may countries do increase amount of respurces?

Answer 9

• import
• technical solutions e.g desalination plants to produce fresh water from saltwater [EXPENSIVE]

Question 10

explain consumption of resources in HICs:

Answer 10

• greater consumption = can afford to buy more resources = higher standard of living

Question 11

explain consumption of resources in LICs:

Answer 11

-consumptio is lower in LICs = cant afford to eitehr exploit avialbale resources or import lacking resources

Question 12

explain consumption of resources in NEEs:

Answer 12

• consumption is increasing
• industry is developing quickly [requires lots of energy]
• inc population & wealth = rapid

Question 13

what factors have lead to a higher demand for food?

Answer 13

• demand for seansonal products all year
• organic produce = ppl concerned abt chemicals, and health
  -as ppls incomes inc = demand for exotic fruits, coffee increased
  [lots of this is imported]

Question 14

how does the high demand for food affects the carbon footprint?

Answer 14

• carbon footprint is increasing
• growing, processing, packaging releases CO2
• transporting foods = food miles = CO2
• the amount of CO2 produced from growing to transporitng = carbon footprint

Question 15

how does importing foods affects carbon footpring

Answer 15

• imporitng foods means more food miles so more CO2 released
  = inc global warming

Question 16

3 reasons why farming has becoming more industrilized:

Answer 16

• farm sized have increased = produce food cheaper
• amount of chemicals used in food procuction increased = pestcides, ferilisers used
• worlers employed in agriculture fell to just over 1.1% due to inc of machinary e.g harvesting

Question 17

explain the demand of water in the UK:

Answer 17

• North & West = high rainfall = have a water surplus [greater suply than demand
  -South & East = high population densities = higher demand = water deficit [demand greater than supply]

Question 18

evidence for demand for water in the UK is increasing:

Answer 18

• since 1975 amount of water in UK homes increased by 70%
• population increase = prediscted by 2040 increase by 6 million

Question 19

what are problems with water pollution/quality?

Answer 19

• crop fertilises washed into rivers & groundwater
• pollutants from vehicals washed into water sources
• chemical & oil spills can pollute water courses
  = EUTROPHICATION

Question 20

why is it important that groundwater is clean?
how has pollition affected UK’s ground water?

Answer 20

• 80% of water in parts of south englands comes ground water
• poluution affects water quality of 50% of groundwater in UK

Question 21

give 2 stragies to manage water quality

Answer 21

• improve driangae systems
• impose regulations of amount & type of fertilisers/pesticides used

Question 22

what does water transfer do?

Answer 22

transfer water from areas w a surplus to areas w a decicit

Question 23

issues with water transfer?

Answer 23

• dams needed are expensive to build
• can affect wildlife in rivers e.g fish migraition distrupted by dams & may reduce biodiversity
• political issues = ppl may not want their water transfered to other areas

Question 24

how has the UKs energy mix changed?

Answer 24

• **1970 **energy relied on fossil fuels = 90% came from coal & oil
• **1980 **discovered gas reserves = 22% of UK’s energy came from gas
• recently = increase in renewable sources 2014 19% of energy = renenwable

Question 25

explain why oil & gas resevers are running out:

Answer 25

North sea oil & gas reserves are being **used up quickly** & production has been declinng since 2000

Question 26

are coal resevers running out?

Answer 26

- still has coal reseves but prodcution has decreased - **less demand** = efforts to reduce CO2 emissions - last deep mine closed in 2015

Question 27

explain shale gas:

Answer 27

- use of shale gas = from underground adds resources - extracted by **fracking**

Question 28

what are the economic issues with exctracting fossil fuels?

Answer 28

- expensive - icreases amount of reserves used - oil expensive to produce - money needed to research other enrgy sources - expensive to build new renewable generators

Question 29

what are the enviromental issues with exctracting fossil fuels?

Answer 29

- burning fossil fuels releases CO2 = inc climate change - oil splis = eutrophication [pollutes water sources] & soil - ecosystems damages and biodiverisity decreases due to building renewable energy generators
