La agricultura orgánica puede ser más rentable en el largo plazo que la agricultura convencional
Organic farming is more profitable and economically secure than conventional farming even over the long-term, according to a new study in Agronomy Journal.
Using experimental farm plots, researchers with the University of Minnesota found that organic beat conventional even if organic price premiums (i.e. customers willing to pay more for organic) were to drop as much as 50 percent. “Doing an economic study like this, it’s important to get as complete a picture of the yield variability as we can,” explains Timothy Delbridge, lead author of the study and a doctoral student studying agricultural economics at the University of Minnesota. “So, the length of this trial is a big asset. We’re pretty confident that the full extent of the yield variability came through in the results.”
Conducted over 18 years, the study found that a conventional farm, rotating corn, soy, oat, and alfalfa over 4 years brought in $273, while an organic farm netted $538. Even if the organic premium dropped by half, it would still be more profitable given that the cost of production was lower for organic, since organic farmers would spend nothing on chemicals. “What we’re looking at here are results between an established organic and an established conventional system. This research doesn’t take into consideration the issue of the transition itself: how difficult or costly that may be,” cautions Delbridge.
Organic farming—which excludes the use of pesticides, herbicides, and GMOs—is considered better for environment, including less pollution, better use of water, and biodiversity-friendly practices. Findings vary, but studies have shown that organic farming is capable of producing similar yields to conventional farming. Organic farms also withstand natural disasters—such as droughts and hurricanes—better than conventional farming, which may be increasingly important in a world undergoing climate change.
