Resource Management

• Why has there been a demand for food?

  There has been an demand for food because of population growth.

  The more people there is, the more food we need.
• What are food miles?

  The food journey from production to consumption
• What is Carbon footprint?

  The amount of Carbon dioxide produced in a products journey.
• Why does the uk produce so much food?

  • A demand for exotic food all year round.
  • A demand for seasonal foods all year round.
• What is an example of a seasonal food and why?

  A strawberry because strawberries can only grow during the summer time.
• 47% of the uks food is imported
• What is the difference between agribusiness and organic farming?

  Agribusiness is a lard scale of pesticides(its cheaper) and organic farming is small scale and includes not pesticides and is far more expensive.
• What is food Insecurity?

  When people aren't getting enough nutritious food to stay healthy
• What are some factors that Cause food insecurity?

  • Climate
  • Pests
  • poverty
  • conflict
• What are some impacts of Food insecurity?

  • famine
  • undernutrition
• What is irrigation?

  Artificial ways to water land
• What are some examples of irrigation?

  • Water sprinklers
  • drip systems-dripping water from small holes that reach directly in the ground
• What is hydroponics?

  When plants grow in nutrient solution, supported by material like rockwool
• Why has the demand for water increased?

  • For appliances like washing machines
  • Irrigation- wide spread of ays to water plants
  • Showers-hygiene
  • Population growth
• What is water insecurity?

  Not having enough clean water
• what is water deficit?

  having too little water
• What are factors that affect water availability?

  • climate
  • geology
  • polluted water sources
  • poverty
• How does climate contribute to water insecurity?

  Most places rely on water from rivers or lakes for water. However, if the climate is to hot, then the water will start to evaporate, causing area to be in drought
• How does geology contribute to water insecurity?

  Normally rainfalls onto impermeable rock, where water can just slide into lakes and rivers. However, if the rock is permeable the water will seep through and can form aquifers(under ground store of water) which is hard to get water from
• How can polluted sources of water contribute to Water insecurity?

  When animal waste or industrial waste gets dumped into rivers or lakes causing lack of access to sanitation.
• How does poverty to contribute to water insecurity?

  To access water in your homes you need a to pay for it, if you do not have enough money to source for water then you'll have to find different ways to get water which can be unsafe.
• What impacts can water insecurity lead to?

  • disease
  • conflict
  • reduced food production
• What are ways to increase water supply?

  • desalination
  • water transfer schemes
  • dams and reservoirs
  • water diversions
• What is desalination?

  removal of salt from saltwater so it can be used
• What is a water transfer scheme?

  a large scale scheme that moves water from an area of water surplus to an area of water deficit
• how can you transport water ?

  You can transport water from canals, pipes and pumping stations
• What is an example of a water transfer scheme?

  The Lesotho water transfer scheme
• How does dams and reservoirs increase water supply?

  During times of water surplus due to heavy rainfall, the water can be kept and stored, ensuring consistent flow of water all year round
• What are the negatives of dams?

  • Dams are very expensive(Chase water in Staffordshire cost 5.5million)
  • it could flood agriculture land
• What is a water diversions?

  When dams raise the rivers water level and this is redirected to another location
• What are the two main processes of desalination?

  • sea water is evaporated until salt is left behind and condensed into fresh water.
  • sea water is passed through a membrane that removes the salt
• 98.8% of Dubais water is made through desalination
• Dubais largest plant produces 140 million gallons of desalinated water every day
• What are most desalinated plants powered by?

  fossil fuels
• Is desalination expensive?

  Yes, a lot of energy is needed
• What are ways to sustain water?

  • water conservation
  • recycling
• How can we recycle water?

  Water from homes can be piped to water treatment plants where it is treated.
• what is water conservation?

  Using less water
• What are ways to conserve water?

  • Dual flush system
  • educating people to have shorter showers and turns he tap of whilst washing your teeth.
• Dual flush systems save up to at least 3.5litres of water with every flush
