# Module 33: Sustainable food production
Mod 33: Sustainable agriculture (fishing too)
- Desertification (see above)
- intercropping vs. monocropping, see ["the three sisters"](https://en.wikipedia.org/wiki/Three_Sisters_(agriculture))
- 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](https://www.youtube.com/watch?v=G__PVLB8Nm4))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
