1985, princess diana and prince charles opened live aid, a concert organised to raise money for the relief of famine-stricken africans
raised more than $125 million, $309 million in today's dollars
what are possible reasons for variation in energy consumption and availability across the world?
less/more acess to technical tools/devices that require energy
not enough money to afford energy ; less people use it
poverty and development
what does physical water scarcity refer to?
when you cannot physically get water
what does economic water scarcity refer to?
when you cannot get access to water available due to economic problems
how stable is the uk in terms of resources?
food - moderate climate, largely influenced by the atlantic ocean, plentyrainfall and mild temperatures; most efficient producers ; fertile soils and gentle relief and advanced technology
water - wetter in the east, water can be transferred from surplus to deficit areas
energy - has considerable fossil fuels, coal was the main source, but oil and gas are used more now. there are reserves of oil and gas beneath the north sea ; several nuclear power plants ; has potential for renewable energy; has 7 of the world's ten largest offshore wind farms
how have the uk's eating habits changed?
less white bread, less full fat milk - buying white bread has dropped 75% since 1947, wholemeal risen by 85%; semi-skimmed milk
less liver - dropped from 36g-3g, chicken and minced beef had rose in popularity
italianisation - pasta purchases have doubled since 2014
cheaper food
freezer revolution - total consumption of canned vegetables dropped by 1/3 as ready made meals consumption went up fivefold
opportunities created from reducing the uk's carbon footprint
economic growth - renewable energy, new jobs
technological advancement - renewable energy, energy efficiency
environmental benefits - reduction in pollution, preservation of natural resources
health improvements - decrease in respiratory diseases, improved quality of life
global leadership -uk as a leader in climate action, influence global environmental policies
challenges created from reducing carbon footprint in the uk
high initial investment
technological reliability - dependence on unproven or emerging tech, integration challenges with existing infrastructure
environmental impact - wildlife, disposal of waste
cultural and social - resistance to change, public awareness and education
policy and regulatory challenges - making effective policies and regulations, balancing national interests with global comittments
why does the uk import so much food?
uk climate is often unsuitable for the production of some foods e.g. cocoa, tea and bananas
there is cheaper food abroad which allows supermarkets to try to outcompete each other for low prices
customers demand greater choice and more exotic foods
strawberries and apples are only in season in the uk in certain seasons yet there is demand all year round
uk produced food can be expensive because of poor harvests and price of animal feed
positive impacts of importing food
less energy is used in growing certain crops in LICs as there is no need for heating greenhouses in HICs, there is less damage to environment
wide range of food are available in our shops all year round, cheaper
negative impacts of importing food
harder to monitor food production standards
people do not buy local produce as much
relying on foreign producers means that if there is disruption, food can be more expensive
increased road traffic, accidents
uses more packaging
less fresh
increased fuel use
what are food miles
the distance that food travels from producer to consumer
what is carbon footprint
amount of carbon dioxide and other greenhouse gases released into the atmosphere due to the activities of humans
what are the alternatives to importing food?
consuming seasonal produce from the uk
only allowing imported foods that cannot be grown in the uk
label origin or food so customers can make informed choices
consuming food produced locally
growing food in your own garden or allotment
organic farming
when additional chemicals are not used in production
locally produced, so food miles will be less
doesn't necessarily reduce food imports
agribusiness
when a farm is run like a large industrial business
large scale, money intensive commercial activities
bird's eye, cadbury's
reduces food imports as they are able to produce food on a large scale
producing more food than they need, reduces carbon footprint, food miles etc
local seasonable food
food that is grown close to where people live, it is in season
strawberries in summer, potatoes in autumn
reduces food imports as goods are produced locally, reducing distance from farm to fork
advantages of water transfer schemes
water for industry and peoples homes, good quality water
boosts industry
you can use what is available to you
disadvantages of water transfer schemes
costly to transport across the country
reservoirs displace habitats and interferes with valleys
evaporation
negative impacts on farmland as more space is needed for water intake
where is kielder located?
area of high land called the pennines
means it receieves more rain than areas in the east which lie in the rain shadow
water collected here is transported southwards and released into rivers that flow to the cities of newcasle-upon-tyne, sunderland, durham, darlington and middlesbrough
facts and figures - kielder water transfer scheme
11km long
reservoir's dam is at the south-east end of the valley, 1.2km long and 52m high
area had rainfall twice the national average
used boulder clay to construct the dam
took 2 years for reservoir to fill up
1,500 engineers, 7 year project
opened by the queen in 1982
opportunities of the kielder water transfer scheme
tourism - more jobs and income
more water - boosts economy
largest hydroelectric plant
provides leisure facilities - water sports, walking, canoes, fishing
provides for industry and homes
challenges of the kielder water transfer scheme
families were displaced
farmland and habitats were lost behind the dam
disturbed wildlife
cost lots of money
takes water a few days to be transported
factors contribution to uk's lower energy consumption
energy efficient appliances
insulation
de-industrialisation
electric cars
factories using robots
more nuclear power
biomass
wood, plants or animal waste burnt for power or used to produced bio fuels
adv: renewable, carbon neutral, multi-purpose, easy for poorer countries to grow
disadv: carbon neutral, takes up farmland, releases co2
wind
turbines use energy of wind to generate electricity
adv: renewable, demand in winter is much higher and the wind levels are higher
disadv: not reliable, can disrupt radio and tv signals, birds can die
tidal
currents of changes in water level caused by tides are used to turn turbines and generate electricity
adv: produces a lot of energy and elecriticity, high capacity, reliable
disadv: extremely expensive, only works twice a day, interferes with navigation of ships, limited locations
solar
energy from the sun heats water to generate electricity
adv: can be used on roofs, can create hot water and generates electricity, energy can be sold back to national grid
disadv: positioning, not enough sunlight
geothermal
water pumped into ground where the heat deep in the earth turns it into steam and drives a turbine to generate electricity
adv: electricity and hot water
disadv: limited to small number of locations, release of greenhouse gases
wave
wind blowing accross water makes waves which drive turbines which generate electricity
energy of falling water trapped by a dam and collected to fall through tunnels where the pressure of the falling water turns the turbines to generate electricity
adv: increase production instantaneously
disadv: located in mountainous areas, difficult to access
fossil fuels
creates jobs, brings money into areas, supports industries
miners will suffer from diseases which will cost money to take care of, very expensive to mine, expensive to import from other countries
carbon captive storage is efficient but expensive
releases co2, waste is visible, destroys wildlife
nuclear
creates jobs, development for new technology in the industry, cheaper
costly to build, store and transport nuclear waste and do decommission
cleaner and less polluting
must be stored safely for years to avoid contamination, dangerous, releases radiation
water surplus
when supply exceeds demand
water security
having access to enough clean water to support good health and economic development
