    Notes:
    Mod 31
    Undernutrition: lack of calories
    Malnutrition: lack of critical part of diet, usually protein (Kwashiorkor)
    https://en.wikipedia.org/wiki/Kwashiorkor

    Famine: one of these impacting a large group, often from crop failure, drought or war/displacement

    Agribusiness: just what it sounds like, the larger conglomerates taking over instead of smaller privately owned family farms. Often use monoculture crops to increase profits, as well as patented seeds and herbicides
    See: Monsanto and Cargill
    GMO crops: in the beginning were just to withstand frost, now into a larger patent issue with GMO seeds and "round up ready crops"
    Mod 32:
    Food energy subsidy (cost factor):
    20 kg of grain to produce 1 kg of beef (20:1 factor, or subsidy factor 20x)
    2.8 kg of grain to produce 1 kg of chicken (2.8:1 factor, or subsidy factor of 2.8)

    Food miles:
    Average 1240 miles from farm to table (more here, unless you shop at the farmer's market)

    Started as a good thing:
    Green Revolution, Norman Borlaug-Mexican famine averted by development of hybrid (not GMO) wheat, called dwarf wheat (large kernel, short stalk).

    Waterlogging: too much water in the soil, roots die (see hydroponics demo at elab)
    Salinization/desertification: using well water for irrigation, salts build up in the soil, infertile soil results

    Pesticides and herbicides: can be persistent or not (DDT, round up)
    https://en.wikipedia.org/wiki/Dichlorodiphenyltrichloroethane



    Mod 33:
    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
    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)
    More than just N-P-K, also micronutrients, slower release time, low salinity

    CAFO: concentrated animal feed operation (e.g. chickens, pigs, cattle)

    Fishery collapse: see cod crisis in N. Atlantic
    Bycatch: killed while harvesting other fish
