Resource Managment - UK Flashcards
uk importing food
reasons
- demand for greater choice
- uk climate unsuitable for growth of certain foods eg bananas
- uk produced food can be expensive bc poor harvests and price of animal feed
- food from abroad cheaper
uk importing
costs
- strain on water supply
- farmers are exposed to chemicals
- land that used to be for local ppl is now for uk
- 17% of carbon footprint is food related
- harder to buy local produce
- chemicals may have a negative impact on health
uk importing
benefits
- jobs are created
- government makes more money from tax
- wages forlocal people
- lower cost
- more choice
food miles
distance covered supplying food to consumers
food
limiting carbon footprint
- eating seasonal uk products
- limiting imported foods
- eating locally produced
- grow ur own food - over 1/3 ppl grow their own produce
agribusiness
- large scale, capital intensive, commercial farming
- common: vertical farms
agribusiness
advantages
- modern techinques increases yield = food security
- reduces costs
agribusiness
disadvantages
- growth of monoculture
- small farms bought by large companies
- use of chemicals = less biodive
- machinery reduces job opps –> rural depopulation
- field size increased = removed hedges = less biodive
enregy
changing demand
over 30yrs
- domestic dropped 12% –> more efficient appliances
- industry dropped 60% –> more efficient, decline of heavy industry
- transport increases, but electric vehicles will change this
energy security
uninterrupted, affordable energy
energy mix
range of energy sources in a country/region
causes energy insecurity
- limited supply
- high demand –> increased pop + tech reliance
- hazards
- conflicts
- insufficient infrastructure
- over reliant on one/imported source
energy
changing mix
- government invests in renewables
- difficult access to remaining supplies
- EU emissions regulations
- reduced supplies of non-renews = increased reliance on import non-renews
renewables
sources that can be used again and again and will not run out
process
fracking
- water, sand, chemicals infiltrate porous rock
- pressure is created, pushing the gas out
pros n cons
fracking
- profitable
- pollution of ground water
- linked w/ low-level earthquakes
- requires a lot of water
pros n cons
nuclear power
- **construction of new plants = more jobs
- cleaner than fossil fuels
- cheaper tha fossil fuels**
- risk of radioctive leaks
- waste water bad for local ecosystems
- old plants gotta be decomissioned = spenny
- storing/transporting toxic waste is v spenny
- waste gotta be safely stored for yrs to avoid contamination
- plants are v spenny to build = hinkley point may bost £18bn
pros n cons
renewables
- **job creationg
- reduced co2 footprint
- offshore turbines can act as an artificial reef –> habitats
- land used for turbines can also support other activites**
- high construction costs
- sea turbines effect ecosytems and currents
- noise pollution –> effected bird migration and bat life
- construction can harm env
- visual impact –> less tourism = local economy shrinks
pros n cons
fossil fuels
- **creates jobs
- carbon capture and storage reduces co2**
- mines r ugly, dusty, noisy
- creates co2 = acid rain
- must be imported to meet demand
- hard to access remaining domestic supplies
- miners often suffer diseases = cost on NHS
water
changing demand
- increased wealth –> eg. dishwashers
- improved personal hygiene
- demand for out of season food
- increased industrial production
- increased leisure
- increased pop
water deficit
- demand is greater than supply
water surplus
supply > demand
water stress
demand > available amount during a certain period
water transfer
elaborate systems to transport water from one river basin to another
costs
national water grid
- expensive
- impact on env
- disruptive to ecology
- increased carbon emissions
- potential droughts
- displacement of local communities
affects of poor water quality
- increased water temp
- jobs lost
- pesticide
- sewage can spread disease
- eutrophication
- contaminate drinking water
- poison wildlife
water managment strategies
greenroofs + walls
- filter pollutants
- absorb co2
- reduce runoff
water managment strategies
education campaigns
inform the public abt appropriate use of water systems
water managment strategies
waste water treatment
- removes solids, chemicals, minerals, bacteria and algae
1. screens trap rubbish
2. stones and grit are removed
3. sludge is removed
4. good bacteria removes any harmful chemicals etc
5. water is allowed to rest again and let anything else sink to the bottom
water managment strategies
pollution traps
use of channels line w/ grass alongside major roads
water managment strategies
infrastructure
reduces spills + accidents, prevents overflowing
