Module 33: Sustainable food production

Mod 33: Sustainable agriculture (fishing too)

  • Desertification (see above)
  • intercropping vs. monocropping, see "the three sisters"
  • Contour cropping: saves space, reduces runoff, preserves top soil (e.g. our garden, most of Asia)
  • No-till ag: same idea, retains organic material in topsoil, reduces erosion by wind and water
  • IPM: integrated pest management (see Lalamilo Farmers)
  • Organic agriculture (also mentioned in Portlandia and Colin the Chicken)More than just N-P-K, also micronutrients, slower release time, low salinity
  • CAFO: concentrated animal feed operation (e.g. chickens, pigs, cattle)Usually inorganic feed (purines), hormones and other drugs
  • Methyl xanthines: caffeine, theobromine, theophyllineevolved plant poisons for insects:

  • Xanthine: group name
  • Caffeine: energy drinks, coffee, soft drinks (to offset drowsiness from insulin spike)
  • Theobromine: chocolate
  • Theophylline: tea (also a bronchodilator-helps breathing)
Actually, almost anything that ends in -ine is usually a plant poison evolved to kill insects:
  • nicotine: tobacco
  • caffeine: coffee, tea
  • cocaine: coca plants
