Resource Management Flashcards
what is the significance of water?
- drink, wash, waste, grow
- average person In UK uses 150l each day
- only 4% used for drinking
what is the significance of energy?
- heat homes, power, process food
- depend on how wealthy and where you live on what energy you get
- traditionally from burning wood
- today there is renewable energy
what is the significance of food?
- calories for work and play
- amount of calories depends on job
what is the global in equalities of energy?
- poorest 1 billion consume 4% of energy
- richest 1 billion consume 50% of energy
what is the global in equalities of resources?
- between 2003 and 2011 increase in 53% of resources in China
- LIC’s and NEE’s demand more resources
how have the demand of foods in the Uk changed?
- higher demand for seasonal foods, exotic foods
- such as strawberries imported from South Africa
how has the carbon footprint of our food grown?
- increasing number of ‘food miles’
- 9% of emissions from growing food
- higher food miles more Co2 produced
- people are starting to become aware of ‘food miles’ and sourcing local food
what is agribusiness?
large scale, industrial farming where processes from the production of seeds and fertilisers, to the processing and packaging of the food are controlled by large firms.
how is farming becoming more industrialised?
- increasing farm sizes

- population densities are going to change, lots of new houses in the south east
how is the Uk matching supply and demand for water?
-transferring water from areas of surplus to areas of deficit
how has the Uk’s energy mix changed?
- -traditionally relied on fossil fuels
- use of nuclear energy increased in the 1990s
- recently a shift from fossil fuels to renewable resources
how is the UK’s supply of oil, coal and gas running out?
- North Sea oil and gas reserves are being used up
- decline due CO2 emissions
- shale gas is being considered by a process called fracking
what are the economic issues of exploiting energy sources?
- extraction of fossil fuels is expensive
- North Sea oil is expensive to produce and may be more expensive than it can be sold for with changes in pricing
- money is needed for research into alternative energy sources
what are the environmental issues with exploiting energy sources?
- burning of fossil fuels releases CO
- fracking may pollute ground water and cause mini- earthquakes
- power stations and wind farms are ugly
