Resource Management Flashcards
why does the world need access to food
- without access to nutritious food, ppl become malnourished ie iron deficiency affecting children’s development
- malnourishment increases likelihood of getting diseases (1/3 of under 5’s die from diseases linked to m.nourishment )
- ppl without food don’t perform as well in school, lacking skills needed for a country’s development
- m.nourishment stops ppl working, harming their and their counry’s economic wellbeing
why does the world need access to clean water
- needed for drinking,cooking,washing. no proper sanitation causes water sources to be polluted by sewage
- waterbourne diseases (cholera) kill many ppl each year
- walking long distances collecting water has economic impact bc ppl spend less time in education/working
- needed to produce food, clothes & many other products
why does the world need access to energy
- needed for industry, in homes & transport. electricity allows industries to develop creating jobs making countries richer
- the lifestyle in HIC’s depend on hhaving a large & stable supply of enegy
- w/out electrity ppl may burn wood for cooking,light,heat leading to deforestation & ppl walking long way to get wood
- electricity powers pumps for wells, providing safe waater for communities
why is the global distribution of resources uneven
- some countres dont have own energy reserves
- some have dry climates unsuitable for food production
- to access more resources, countires must import them/ find tech based solutions which can be expensive
name the general trends of the comsumption of resources. what does this depend on?
depends on a country’s wealth & their availablility of resources
- higher consumption in HIC’s
- consumption is rapidly increasing in NEE’s
- consumption is lowest in LIC’s
why is the consumption of food increasing in UK? give facts
ppl want seasonal food all year round
- incomes in UK increased so ppl buy more exotic fruit/spices from LIC’s
- before 1960 fruit/veg produced locally&seasonally. now demand for season food increased so we import to meet this demand
why is the consumption of water increasing in UK? give facts
demand for water varies accross UK
- demand increased 70% since 1975 bc more appliances. population expected to increase by 10mill by 2040. new homes being built in south east
- north west UK. high rainfall & low pop. density = surplus
- s.east UKlow rainfall & high pop.density = deficit
why has the consumption of energy changed in UK? give facts
- since 1970, 90% enegy from coal & oil
- 1980, large gas reserves in north sea meant 22% energy from gas
- 2014, shift towards renewable energy (wind & bioenergy)
- all coal power stations expected to close by 2025
how can UK even out the distribution of water in the country
water transfers can help maintain supplies
- transferring water from areas or surplus to deficit causes problems bc ppl dont want their water transferred elsewhere & building dams are expensive & disturb fish migration

why is the UK carbon footprint of food growing
carbon footprint of our food is growing
- our food miles are increasing and carbon footprint (g.house gases produced in the packaging/transporting of food)
- ppl are becoming more aware of this so try to buy locally produced goods
why is UK farming is becoming more industrialised
- since 1960, been growth in agribusiness (large scale farming run by large business farms) meaning UK farms & fields getting bigger
- more chemicals used (ferilisers for crops, special animal food to make them grow bigger)
- fewer workers needed on farms (mechanisation)
- increasing farm size means hedges cut down (loss of habitat) so less biodiversity & more soil erosion bc of large machines
why are UK’s supply of coal, oil , gas running out
north sea oil & gas rapidly used up and production declining
- production of coal fallen since 1900s
- decline in demand for coal to reduce CO2 emissions
- cost of mining increasing.
- underground shale gas used more & extracted by fracking
what environmental issues does expoliting energy cause
- burning fossil fuels relaeses CO2 & greenhouse gases
- fracking pollutes groundwater & causes earthquakes
- oil spills/ nuclear disasters leak toxic chemicals into water/soil/the air
- ecosystems damaged by renewable energy ie wind farms
- power stations/wind farms are eye sores
what economic issues does expoliting energy cause
- extracting fossil fuels is expensive, expecially north sea oil
- nuclear energy expensive to produce
- money is needed to research alternative energy sources
- renewable energy not reliable so UK must import
