• Fracking


  • Mining gas trapped in shale
  • Deep pockets in rock
• Fracking


  Earthquakes could start occurring
• Fracking


  Water + Sand used to break topen shale
• Economic issues


  • Extracting fossil fuels can be expensive
  • Money is needed for research
• Burning fossil fuels


  Releases CO₂
• Fracking


  • Could pollute groundwater
  • Cause mini earthquakes
• Global consumption of food is increasing as population increase + people have more money to spend
• Risk of food insecurity

  • Low risk: UK, France, USA
  • High risk: Chad, Ethiopia
• Impact of food insecurity

  • Undernutrition
  • Rising prices
  • Soil erosion
• Types of irrigation


  • Drip system
  • Sprinkling
  • Gravity flow
• Drip irrigation


  • Drip-feeding water from small holes in pipes directly onto soil
• Agribusiness

  Intensive farming to maximise food production
• Factors affecting food supply

  • Conflict
  • Crops and livestock destruction
  • Poverty
• Poverty means people can only have what they can grow as they can't afford to import
• Water supply is not enough for everyday living and to grow crops
• Genetic modification


  • More crops in small area
  • Crops can be drought resistant or disease resistant
  • Crops can have more nutrition/minerals
• Global warming


  Countries become too hot/dry to grow crops
• Fracking


  Gain gas and soil

• Hydroponics


  Growing plants without soil
• Hydroponics is not intermediate technology
• Components of hydroponics


  • Gravel
  • Water
• Aeroponics


  Growing plants with the roots suspended in air and periodically misted with nutrient solution
• Aeroponics


  1. Growing plants

  2. Spraying water and nutrients to the roots

  3. Reusing the water
• Hydroponics


  • Grows plants without soil
  • Requires less water than soil-based growing
• Hydroponics is very expensive, only suitable for high-value crops
• Hydroponics


  • Lower risk of disease as no soil
