  • Describe the ways that technology can increase food production. How acceptable/ sustainable?
    • Hydroponics
      • Large quantities produced
  • Fertilisers, pesticides, herbicides
    • Describe the ways that technology can increase food production. How acceptable/ sustainable?
      • Hydroponics
        • Large quantities produced
    • Increase yields
      • Decrease hunger/malnourishment
    • Genetic resistance
  • Decrease biodiversity
    • Fertilisers, pesticides, herbicides
      • Increase yields
        • Decrease hunger/malnourishment
      • Genetic resistance
  • Adverse health effects
    • 1-5 million have acute poisoning and die/year
  • Herbicide tollerance
    • Biotechnology- GM crops
      • Developmental process v. expensive
  • Insect tollerance
  • Virus tollerance
  • Delaying ripening (preservation)
    • Biotechnology- GM crops
      • Developmental process v. expensive
  • Increasing yields
    • Virus tollerance
  • Genetic uniformity increases vulnerability to disease
    • Decreased biodiversity
      • 750,000 pepper picked a week at Thanet Earth/week
      • High initial cost
        • Drought tolerant
        • Reduced use of pesticide
          • Grown in water so in areas of poor soil quality or little space crops can be produced
            • Hydroponic crops can be grown in stacks above each other
            • HIgh energy output
              • Mechanisation of farming
                • Increase productivity
                • Pollution
                • Encourages large scale production
              • irradiated the need for jobs
                • Mechanisation of farming
                  • Increase productivity
                  • Pollution
                  • Encourages large scale production
              • Deforestation
                • Soil erosion
                  • Improves quality of farm produce
                    • Technology may be a but advance and too expensive for LEDCs perhaps more suited to NICs / BRIC countries
                      • Suitable but would have to be careful thats the poorest in society are not cut off
                        • Suitable but tighter regulations/education on handling the chemicals
                          • would have to be set to avoid deaths
