what is needed for basic human development
food,water and energy
what happens when people cant access enough safe nutritious food.
- they can’t eat balanced nutrients
- causes malnourishment
- malnourishment and limit a child’s development and also increases the likelihood of getting ill
- globall one third of all under 5s die from diseases linked to malnourishment

- without sanitation water can get polluted by sewage
- water borne diseases liek cholera kill many people each year
- water is needed to produce food and clothes so it has a big impact on livelihoods
what happens when there isnt enough energy for a country
- countries need energy for industry,transport,homes
- it allows countries to develop
- without electricity people in lower income countries may ahve to use other resources liek burning wood - deforestation

it can affect a persons ability to attend work or school, preventing them from learning valuable skills to help their country develop
what is the global distribution of supplies like
uneven
what is consumption of resources like in HICs
consumption is greater because they can afford to buy the resourcesthey need - they can expecta higher standard of living.
what is the consumption of resources liek in NEEs
increasingly rapid in countries like CHina
-industry is developing quickly and populationa nd welath are alos devleoping quickly
what is consumption of resources liek in LICs
consumption is lower in countries like Uganda as tehy cant afford to important the resources they need and they cnat afford to exploit available resources (oil)
what are seasonal foods
foods that are only available in the season it grows - fruit and veg is imported from other countries to meet the demand of seasonal food all year around.

what are organic products
- people are beocmign more concered of the enviromental impacts of food production
- organic foods are strictly regulated ( like no organic fertilizers are used)
how is the carbon footprint of our food growing
- up to 10% of Uks total greenhouse gas emissions in 2017 came from agricuture
- transporting,growing and packaging food creates CO2
- peopel are becoming aware of this and are now looking a locally sourced food like farmers markets

which areas of teh Uk get the highest rainfall
the north and the west - these are areas of water surplus
which areas what highest population density and how doe sthis affect water supply
the south east and midlands have the highest population density so theres a high demand for water - tehy are areas of water deficit
how has demand for water in the UK increased
- since 1975 teh amoutn of water used by households has gone up by 70% - mainly because people have more appliances that use water
- uk popualtion predicted to rapidly icnrease
- popualtion density is changing
what are some problems that lead to water pollution
- nitrates and phosphates from crop fertilizers are washed into rivers
- pollutants from vehicles are washed into river soruces through runofff when it rains
- chemical and oil spills from factories can pollute local water sources and groundwater
what percent of of water coems from groundwater in southern england
80%
how is pollution affecting water
nealry 50% of ground wateris affected by pollution
what is water transfer
transferring water from areas of surpuls to areas of deficit.
what issues can arrise due to water transfer
- the dams and aqueducts that area needed can be expensive to build.
- it can affect wildlife that live sin rivers
- there might be political issues where people might not want their water transferred to another area
how has teh Uks energy mixture changed
- tradionally fossil fuels - in 1970 91% of uk enegryc ame from coal and oil
- discorvery of large gas reserves under north sea meant in 1980 - 22% of uk energy supply was supplied by gas
- shift towards renewable energy - by 2022 over 38% of all electricity in the UK was generated from renewable sources
- wind and bioenergy - biggest sources
why has coal productions decreased in the Uk
- the oil and gas reserves being used up swiftly
- less of a demand due to an effort to reduce CO2 emissions
