Flashcards in Resource Management Deck (78):
What are resources?
A supply of something that has value (e.g. water, energy, food)
What are the three most important resources?
Water, energy, food
How are resources spread over the world?
Where tends to have most resources?
Where tens to have the least resources?
Why is resource management difficult?
Population is growing and resources are running out
What is malnutrition?
Poorly balanced diet lacking in vitamins and minerals
What are the problems of malnourishment
Illness, people can't work so country suffers
What is water used for?
In the home (domestic use)
Water crops (Agriculture/ farming)
Why is water unevenly distributed around the world?
Climate and rainfall
Which countries have a shortage of water?
Many in Africa
What is water scarcity?
Not enough water
Which type of country uses the most water?
Which type of country uses the least water?
In MIC's and LIC's, what is water used for most?
In HIC's. what is water used for most?
Domestic (in the home)
Why is energy use increasing?
The world is becoming more developed
What is energy used for in the home?
What is the link between energy use and economic development?
As countries develop they use more energy in factories, become richer and use more energy in the home.
Demand for food is...
Why is demand for food increasing?
What are food miles?
The distance food has travelled to get to the UK
Why does the UK import food?
We don't have the climate for some foods (e.g. bananas) or we have a short growing season (e.g. strawberries)
Why do people want to buy local food?
Low food miles so less carbon added to the atmosphere transporting food.
What is agribusiness?
Intensive farming to maximise food production using technology and chemicals. Lyford House Farm does this.
What is organic produce?
Food grown without using chemicals (expensive). Riverford Organic farms do this.
Demand for water is...
Why is the demand for water increasing in the UK?
More houses being built
Water based appliances (e.g. dishwashers)
What is a water surplus?
More water than needed
What is a water deficit?
Not enough water
Water surplus happens when...
High rainfall and low population density (North West UK- Lake DIstrict)
Water deficit happens when...
Low rainfall and high population density (South East UK- London)
Water stress is when
Demand is bigger than supply
How can we save water?
Use recycled water
More efficient appliances
What is water transfer?
When water is moved from an area of surplus to deficit
Name an area where water is transferred from
Why do people think transferring water is a bad idea?
Transporting water releases carbon dioxide
How is water quality managed?
Monitoring river water quality
Filter water to remove sediment
Adding chlorine to water
Strict rules on the uses of water.
How has groundwater been polluted?
Chemicals from factories
Chemicals from farming
Water used in power stations put back into rivers
What has happened to energy use in the UK?
Why has energy use decreased in the UK?
Less industry/ factories
Low energy appliances
Better building insulation so less heating needed
What has happened to coal use in the UK?
What has happened to oil use in the UK?
What has happened to gas use in the UK?
What has happened to renewable energy use in the UK?
Does the UK produce all of its own energy?
No, it also imports from other countries such as Russia
Why has the use of coal decreased in the UK?
It produces greenhouse gasses when burned
What is fracking?
Pumping water deep underground to crack rocks which releases trapped gas.
Why is fracking controversial?
Could cause earthquakes
Can pollute underground water
List two economic impacts of using nuclear energy
Very expensive to build
List two environmental impacts of using nuclear energy
Waste is radioactive and dangerous
Waste water is warm and harms local ecosystems
List two economic impacts of wind farms
Expensive to build
Might reduce visitor numbers to an area
Might increase visitor numbers to an area
Lower energy bills for locals
List two environmental impacts of wind farms
Building can impact environment
Wind farms do not produce harmful gases
Which type of country has high energy consumption (use)
Where in the world is energy consumption (use) low?
What is an energy surplus?
Produce more energy than what is used
What is an energy deficit?
Use more energy than what is produced
What factors affect how much energy is produced?
Cost- some are expensive (e.g. oil rigs)
Technology- good technology means we can get to oil which we never used to be able to reach as it is deep underground
Climate- sunny and windy locations good for solar and wind energy
Physical Factors- coal, oil and gar are only found in certain areas
Political factors- some countries in Europe want Iran to stop producing nuclear power in case they use it at war/ for nuclear bombs
Why is global energy consumption (use) increasing?
As countries develop (get richer) they use more energy. Global population is increasing
What is energy insecurity?
When countries don't produce enough of their own energy so import it from other countries
How can a country become more energy secure?
Try to extract more of its own energy,
Make agreements with other countries in buy energy,
Use less energy/ save energy
Why doe people not want to extract oil from the Arctic?
Very sensitive environment, oil spill would be very damaging, very expensive to extract oil there
What is the link between energy and food?
Energy is used to grow crops. Crops like maize and sugar are used to produce energy.
What is an impact of energy security on industry?
Some countries have power cuts because they don't have enough energy. This can cause factories to shut down and cost a country a lot of money.
How might energy shortages cause conflict?
Russia sells gas to Europe, it could raise prices or stop supply.
Name one way we can increase energy supply
Use renewable energy
What is biomass energy?
Burning dung (animal poo) or plants
How does wind energy work?
Turbines on land or at sea are turned by wind to generate electricity
How does HEP (hydro-electric power) work?
Water flows through a dam to turn a turbine and create electricity
How does tidal energy work?
Dams near the sea, turbines are turned when the tide comes in and out which generates electricity
How does geothermal energy work?
Water is heated underground by naturally hot rocks, creates steam, steam turns turbine which creates electricity
How does wave energy work?
Waves force air into a chamber where it turns a turbine linked to a generator to create electricity
How does solar energy work?
PV cells on solar panels convert sunlight into electricity.
What are fossil fuels?
Coal, oil and gas formed millions of years ago.
Why is nuclear energy not a popular option?
It produces radioactive waste which can stay dangerous for over 100 years.
Where is most natural gas found?
Russia, Iran and Qatar
List two advantages of extracting natural gas
Cleanest of all the fossil fuels
Less risk of accidents than oil
Transported lots of ways (pipes and tankers over land or sea)
Quite a lot of gas left
