RESOURCE MANAGEMENT Flashcards
(13 cards)
food
lack of can lead to malnourishment which is a lack of nutrients - undernourishment is a lack of any food
malnourishment can lead to disease
water
drinking, cooking and washing - water borne disease such as cholera - water is needed to produce food and clothes
energy
industry and transport and homes - electricity can develop industry therefore creating jobs - without electricity poorer countries may have to use wood which can lead to deforestation
also powers pumps which transport water to peoples homes
uneven distribution of resources and uneven consumption
very hot climates not suitable for food production
may need to import or use technology, this is expensive
so a consumption depends on a countries wealth and availability
different types of food are becoming more popular
high value - as peoples income increase exotic food such veg and coffee have become more popular, these are usually grown in LIC’s and imported to HIC’s
seasonal - fruit and veg is imported to meet the demand
organic - more concerned about environmental impacts of food production and how chemicals can affect their health - lots is imported
carbon footprint of food is growing
10 percent of uks total GG emissions came from agriculture
food miles means co2 and co2 means global warming
farming becoming more industralised
agribusiness - large scale industrial farming
so farm size has increased, amount of chemicals used has increased
demand for water varies across the uk
the north and the west of the uk have lots of rainfall meaning it is in water surplus - south east and midlands have a high population density meaning a high demand so water deficit
more appliances means more water usage
more population means more demand
water pollution needs to be managed
farming chemicals such as fertilisers wash into rivers and groundwater
pollutants from vehicles washed into water sources through runoff when it rains
energy mix
traditionally relied on fossil fuels
discovery of large gas reserves under the north sea means 22 percent was supplied by gas
recently there has been a shift towards renewables
wind and bioenergy are the biggest renewables
uk supplies of coal, oil and gas are running out
north sea reserves are being used up
shale gas from underground has been considered through the process of fracking which was banned in 2019
extraction economic issues
expensive
cost to consumer of renewables is high
money is needed for research of new sources of energy
extraction environmental issues
co2 from burning fossil fuels
fracking may pollute groundwater and cause mini earthquakes
oil spills can leak harmful chemicals into water and soil
