P2 UK Food,Water,Energy Flashcards
What is the significance of food for economic and social well bieng?
Economic - provides many jobs, grow own food to save money
Social - vital for health, nescessary to live a healthy lifestyle, can be used at social gatherings and events
Why is energy important for social and economic well being?
Socially - saved time, more time for social activities, helps mental health. Can be used to remain in contact with people, fun activities such as the cinema.
Economic - many jobs provided, transport
Why is water good for social and economic well being?
Social - swimming, bathing (methyl health), cleanliness (health)
Economic - jobs provided
Global inequalities in food:
.some area have more fertile lands
.some areas have more suitable terrain
.some areas have more suitable climates
Global inequalities in energy
.some may have good access to energy but are unable to afford it
.some countries may have bad access to energy
Global inequalities of water
.some places may have low physical scarcity (low rainfall)
. Some places may have low economic scarcity which means they cannot treat dirty water or infrastructure to collect water to make it easily available
.corporate exploitation - take many resources from LIC’s as they need money
What are the issues with the UK consuming such large amounts of non seasonal produce?
.many food miles
.dont pay the farmers fairly
How many tonnes of vegetable and cut flowers does Kenya prepared each night to be sold in UK supermarkets the next day?
350 tonnes
What food constitutes the largest proportion of kenyan food imports to the UK?
Leguminous vegetables
How long do cut flowers from Kenya have to be in supermarkets from the time they were picked?
24-48hours
How many Kenyan ’s does horticulture employ directly and how many does it employ indirectly (eg in transport)?
Directly - 70,000
Indirectly - 20,000
Is Kenya an HIC, LIC or NEE?
LIC
Where is Kenya located?
In east Africa, close to the equator
What % of Kenya population work in agriculture?
75%
How does the multiplier effect happen in Kenya?
Horticulture creates jobs for local, the good produced are sold increasing Kenya’s income and providing more jobs for more people which then causes the cycle to repeat.
Advantages of kenyan imports
.provides jobs for kenyan
.allows the uk to eat non-seasonal produce
Disadvantages of kenyan imports
.doesnt feed locals
.uses up scarce resources (eg water)
.many food miles
.impact on environment (eg. Food miles, pesticides)
.lotus of food wasted
Advantages of organic food
.no chemical pesticides
.dont feed animals antibiotics
.reduced waste (wonky veg)
.uses 30% less energy
.less food miles
.supports local farmers
.health benefits
Disadvantages of organic foods
.more expensive
.less quantity produced
.not as attractive to look at
Positives of local produce
.less food miles
.farmers paid fairly
.encourages seasonal diets
.fresher produce,higher nutritional value
.creates local jobs and supports local economy
What is an agribusiness?
.agriculture conducted on strictly commercial principles
Why is there a trend towards agribusinesses in the uk?
.cheaper
.large yields - more profit
What water deficit?
When water demand is greater than supply
What is water surplus?
When water supply is greater than demand
What issues are caused by poor water quality?
.toxic waste can poison water (bio transfer)
.increased water toxins can lead to death of wildlife
.more fertilisers-more nutrients in water - more growth of algae - eutrophication - death of wildlife
.pesticides can kill important parts of the ecosystem
.mycobacteria in sewage can spread disease
.
What causes water pollution?
.chemicals and fertilisers from farmland
.rubbish
.pollution like oil from boats
.sewage containing bacteria
How can we manage water quality in the UK?
.pollution traps
.green roofs and walls
.waste water treatment
.education campaigns
.local water treatment
.legislation
What are pollution traps?
Traps placed by roads or motorways that are close to rivers and water courses in order to catch pollution
What are green roofs and walls?
In cities, new buildings often have these.they naturally filter out pollution in rainwater and also reduce the risk of flooding by reducing runoff.
What is waste water treatment?
Better sewers and water mains can prevent spills and accidents but can lead to higher water and sewage bills
What is local water treatment?
Local water treatment plants remove suspended soils such as silt, bacteria, algae chemicals and minerals to produce clean water for human consumption.
How is the UKs energy mix changing?
Moving more towards renewables and away from fossil fuels
How is the uks supplies of coal gas and oil changing?
We are running oit of supply.
Although there is lots left, difficult to reach a and it is cheaper to import from abroad as cost of reaching our supplies is very high.
Uks reserves of oil and gas are in decline leaving us reliant on other countries for oil and gas, this makes us vulnerable
Why is food consumption increasing in the uk?
.growing population
.increasing wealth - people can afford to buy more food
