Unit 2 topic 2 geography
- Abu Dhabi
- 30,000 hectares of land in Sudan for agriculture
seeing as Abu Dhabi is a desert with limited water
- The land was given to them free of
charge in exchange for tech
experties
- good idea?
- Yes because it give the country a food supply
- They have good connections with Sudan
- With food prices increasing and
might have shortages they have
enough food when it becomes
hard to come by
- Education
- 240 litre bins for food and
drink cans
- For recycling
- Empty each week
- Advise on reusing materials
- Keeping a cardboard box next to printers
- To be used as recycling boxes
- free compost bins for fruit and veg peelings
- And a garden waste collection
- Thomas Malthus
- 1798 he wrote an essay about population
- He said natural checks would decrease the population
- He believed that humans job was to keep
the population low
- It would get to a manageable level before
rising again
- He believed that population grew exponentially (1,2,4,8,16 ect)
- He believed the population
would decrease from
starvation
- Ester Boserup
- People shouldn't give in to disease and famine
- worked in the united nations
- She dint like natural checks
- So she argued that food
production doesn't limit
or control the
population
- She claimed that growth
controls farming methods
- She used the term 'agricultural
intensification' to explain how how
farmers can get more food from the same
field increasing their yield
- Black gold
- Peak gold
- When oil production reaches it maximum
- When it is reached oil prices will increase
and become difficult to extract
- The future
- Renewable resources
- Solar, wind
- Huge increase in oil prices
- Difficult to extract
- Leads to wars over oil
- Agreements made to secure oil from other countries
- Reserves
- Soon there will be less oil to extract
with could cause wars
- Oil consumption
- In 1900, was 1 million barrels day of oil made
- 2011 is 87 million barrels a day of oil
- America consumes 25% of the worlds oil
- Predictions of 2030 is 116 million barrels a day
- But industry say its
impossible to produce 100
million a day
- Hydrogen Economy
- Advantages
- Easy to split the water to hydrogen and oxygen
- Can be done anywhere
- Harmless to the environment
- Disadvantages
- Splitting takes a lot of electricity
- End of crisis
- Renewable so won't rely on fossil fuels and countries can be indipendant
- Involves
- Taking hydrogen and using it to make electrisity
- What is it
- Hydrogen is the most abundant element in the universe
- Using hydrogen to power cells and create electrisity
- Creates completely clean energy
- Conservation
- Reducing domestic energy consumption
- UK government affered large subsides for installing
private and commercial wind turbines and solar panels
- House holds with PV panels get paid for every
kwh of energy put on the national grid
- Energy companies could get grants for
building turbines
- 100% of grants
- Available to low income houses
- Or who live in an area with high fuel poverty
- Loans - repaid instalments that are added to the house hold
- These loans pay for house improvements
- They are added to the electrical bill over a 7 year period
- Recycling
- To make six 1 litre plastic bottles require 1 kg of oil
- Uk house holds are now recycling more than ever
- In 2011 the percentage grew from 11% to 40%
- Still means an average person disposes 263kg of waste a year
- Half goes to land fill
- UK made 7 million tonnes of waste in 2007
which could have been used to create new
power
- Government provide 80% of local authoring
funds so its target aren't met, petunias can
be taken
- The amount of oil used in a
bottle is enough to run a car for
a year
- Governments are giving authorities targets to reach
- To increase the amount of recycling from energy 52% in wales
plantIn 2012-13 to 70% in 2024-25
- Solar power
- Used to create electrical power
- Be used to heat and cool living and work areas
- Solar power generators increased by 85% in 2011
- Solar power is growing quicker than any other renewable energy
- By 2035 renewable energy will be accounting for a third of the worlds energy
- Germany and Italy have the greatest increase
- Reasons for increase of renewable
energy resources
- Low costs
- Rising prices of fossil fuels
- Government subsiding to renewable resources
- Collected by using (PV) plants grouped in panels
