Presentation Transcript

  1. Efficiency of Food Production Systems

  2. Efficiency Calculations Efficiency = energy output energy input

  3. Traditional extensive rice production • Low inputs of energy and chemicals • Low output of food • The efficiency may be high

  4. Traditional Rice Farming in Borneo

  5. Calculate the efficiency of a traditional rice farm in Borneo

  6. Calculations Add to find the total Inputs = 1.085 Outputs = 7.318 Efficiency = output = 7.318 input 1.085 = 6.745

  7. Rice farming in California

  8. Intensive rice production • High inputs of energy, chemicals, fertilizers and fuels • Higher outputs of food • The efficiency may be low due to the high inputs

  9. Calculate the efficiency of this rice farm in California

  10. Calculations Add to find the total Inputs = 14.680 Outputs = 22.370 Efficiency = output = 22.370 input14.680 = 1.520

  11. Compare the two food production systems

  12. Outline which farming system will feed more people. Compare the farming systems to decide which is more sustainable.
