Challenge of resource management Flashcards
significance of food
without enough nutrients people can become malnourished, this makes them ill and prevents people working or receiving education
significance of water
people need a supply of clean and safe water for drinking, cooking and washing
also needed for food clothes and other products
significance if energy
good supply of energy is needed for a basic standard of living people need light and heat for cooking to stay warm and for industry
demand outsourcing supply
demand for recourses like food, water and energy is rising do quickly that supply cannot always keep up.
population growth
global population is 7.3 billion expected to reach 9 billion by 2050, so demand for resources will increase
economic development
as LICs and NEEs develop more energy is needed for industry
development means more water and food is needed as diet improves
Resource Reliance graph
resource consumption exceeds Earths ability to provide
Changing technology and employment
more people in the secondary and tertiary industry so higher demand for electronic and robotics
food in UK growing demand
- imports 40% of food
- increases carbon footprint
- growing demand for exotic food all year round
food in UK impact of demand
- supports workers with income
- less land for locals to grow own food
- farmers exposed to chemicals
Agribusiness in the UK
- farming treating like a large industrial business
- increases food production
- machinery increases efficiency
- employs little number of people
- chemicals damage wildlife and habitats
sustainable foods in the UK
- organic foods have little impact on the environment and are healthier
- reduces emissions by only eating food from UK
- buying locally sourced food support local shops and farmers
- 1/3 people grow their own food
Energy in UK growing demand
UK consumes less energy compared to 1970s, due to decline of industry
energy mix in UK
- fossil fuels
- renewable sources do not contribute to climte change
changes in Uk’s energy mix
- 75% of UK’s oil and gas has been used up
- coal consumption has declines
- UK become too dependant on imported energy
water in the UK growing demand
- average water used by household has risen by 70%
- due to growing population, water-intensive appliances, leisure and greenhouses
deficit and surplus of water in UK
- north and west have water surplus
- south and east have water deficit
- more than half of England is experiencing water stress
pollution and quality of water in the UK
- chemical run-off from farmland can destroy habitats and wildlife
- oil from boats poison wildlife
- untreated waste from industries creates unsafe drinking water
- sewage spreads bacterial diseases
water management
- strict laws limiting amount of discharge from factories and farms
- wate water treatment plants removes dangerous elements and makes safe drinking water
water transfer
- involves moving water through pipes from areas of surplus to areas of deficit
- expensive energy cost
- effects land and wildlife
renewable energy UK
- government investing more into low carbon alternatives
- wind, solar, tidal
- provide job opportunities
- expensive to install
- bad visual impact on landscape
human food
- poverty prevents people affording food
- conflict disrupts farming
- climate change affecting rainfall patterns making production difficult
physical food
- quality of soil
- water supply reliable
- pest, disease can destroy plants
- extreme weather damages crops
increasing food supply
- biotechnology genetically modifies plants to enhance productivity
- irrigation, artificially watering land so crops grow
sustainable food supply
- organic farming, no chemicals
- urban farming
- managed fishing
human water
- pollution from industrial waste
- poverty makes in unaffordable
- lack of waterpipes
- over abstraction, more water taken than replaced
physical water
- climate needs to provide enough rainfall
- geology
impact of water insecurity
- less water available for irrigating crops
- impact economic impact on water manufacturing industries
- diseases in drinking water
increasing water supply
- water diversion, water stored for longer underground preventing evaporation
- reservoirs/dams, control flow and storage of water
- water transfer
- desalinisation, extraction of salt from sea water
sustainable water supply
- water conservation reduce wasted water
- groundwater management, monitoring extraction
- recycling grey water, reusing waste water
The Wakel River Basin
- provides taankas that store water underground
- small dams interrupt water flow and encourages infiltration
- irrigate fields
- sustainable
- greater education for awareness
physical energy
- geology determines availability of fossil fuels
- climate variations affect renewable energy
- natural disasters damage energy infrastructure
economic energy
- extracting fossil fuels is expensive
- infrastructure is expensive
impact of energy insecurity
- damages habitats and wildlife during oil drilling in Alaska
- food production depends on energy powered machines
- decline in manufacturing
increasing energy supply
- fossil fuels power stations made more efficient
- nuclear plant provide cheap dependable energy source
- renewable energy can’t run out
sustainable energy supply
- homes conserve energy
- reducing demand
- electric cars
- public transport
