Saline Agriculture As the Future of Food

Posted by timothy on from the rice-goes-with-shrimp-and-mango dept.

Damien1972 writes "To confront rising salinization, authors writing in the journal Science recommend increased spending on saline agriculture, which proposes growing salt-water crops to feed the world. Jelte Rozema and Timothy Flowers believe that salt-loving plants known as halophytes could become important crops, especially in areas where the salt content of the water is about half that of ocean water."

    What we really need is more research into GM crops which the environmentalists hate for some reason.

    I'll try to field this one. I'm a moderate on the issue. I don't think GM crops are themselves a bad idea, but I am studying environmental law, and I have pretty good exposure to what people in the movement worry about.

    You can summarize the problem with GM crops into a few distinct worries:
    1) A love of "natural" foods.
    2) Worries about crop contamination.
    3) What GM technology is *actually* being used for. (Instead of the "feel good" science.)
    4) Safety issues in the creation of GM crops.

    First, a lot of people worry about "frankenfoods." They don't want "unnatural" crops because they're worried about the safety of these crops. As my use of quotation marks suggests, I'm not a big supporter of this viewpoint, but a lot of customer do feel that way which is one reason why organic food certifications don't allow GM crops. I won't defend this view because it's not my own, and I haven't gotten a good solid explanation of it.

    But it brings us to point 2. Pollen from GM crops is a HUGE problem for organic farmers. Planting GM crops freely in an area can destroy the market for organic crops at home as well as for selling to Europe and other parts of the world where GM crops are disdained by customers. You simply cannot protect your crop against contamination in many cases. (Also, besides market concerns, there's the infamous Canadian patents case, Monsanto v. Schmeiser .)

    The third point is one that really cheeses of a lot of environmentalists. You hear a lot of awesome things in the news about how scientists have invented rice with extra vitamin A or tomatoes with longer shelf life. The truth is that there are really only two major types of changes which companies have fought to get onto the market -- crops that come with their own built-in Bt insecticide and crops that let you liberally sprinkle around the herbicide RoundUp. (A notable exception to this would be GM papaya engineered to resist the papaya ringspot virus which saved the Hawaiian conventional papaya industry while wiping out the organic industry there.)

    Personally, I would have no problem with eating crops modified to be more healthy, but both of the above practices do nothing but help prolong the survival of crop monocultures. A lot of farming pest problems exist largely because farmers fight tooth and nail to plant the same plant over and over again, providing excellent feeding grounds for pests and opportunistic species. The use of Bt has taken a surprisingly long time to create resistance pests, but hey, so it begins. Oh, and RoundUp resistance is starting to become increasingly common, meaning that farmers are going to start turning to more toxic chemicals.

    It's like disease resistance and the use of antibiotics in farm animals, another tragedy of the commons situation. People realized that if you give cattle antibiotics, they grow larger, so farmers started pumping cattle full of a variety of antibiotics. One by one, bacteria have become resistant in the animals themselves, through plasmid swapping in the soil and environment, and through exposure throughout the environment thanks to runoff of cattle urine and wastes into streams. So, they keep trying new chemicals as the old ones cease to work (or in the case of tetracycline resistance endanger human health).

    So, as insecticides & pesticides become useless, farmers will turn to increasingly more hostile and dangerous chemicals to farm. ...Which they wouldn't need so much if practiced more sustainable agriculture methodology. But the USDA subsidizes the current monoculture-friendly, heavy petroleum byproducts using methods, so as game theory suggests, no one wants to change.

    Anyway, the la
