The Benefits of Agroforestry
Organic bananas are more than healthy bananas. They are cultivated in
the shade of the natural forest, along with other types of fruits
and vegetables in a multi-culture system called agroforestry.
Agroforestry prevents further deforestation, by maintaining or restoring
natural forest, which also helps to produce oxygen, promotes biodiversity
and sequesters carbon. Soil is naturally protected from erosion and
nutrients are constantly replenished in the soil by the plants themselves.
This system also allows small farmers to diversify their production.
In contrast, most conventional banana growers clear-cut large areas
of diverse, tropical rainforest to utilize highly fertile soil. They
rarely rotate crops, and continue planting until essential nutrients
are stripped from the soil, erosion occurs and production declines,
requiring them to cut more natural forests to plant new fields of
bananas. As a general rule, they plant row upon row of the same species,
which is why this is called monocultural farming.
In the agroforestry system no agrochemicals are used, which further
protects the land and water systems from pollution. The majority of
conventional banana plantations, however, use an array of agrochemicals.
They use chemicals to clear ground for crop growth and others to maintain
fertility. They apply nematocides against the worms that might attack
plant roots and crop dusters drop chemicals to protect the plants
against black sigatoka, a fungus that shrinks the fruit and eventually
kills the plant. Also, plastic bags are filled with a neurotoxic pesticide
and tied around the bunches of fruit to protect them from pests. Pesticide
use in conventional plantations can be as much as 20 times greater
than the average use on crops in industrialized countries, according
to the Pesticide Action Network North America (PANNA).
The use of these chemicals as well as planting
techniques lead to a vicious cycle in which an increasing amount of
chemicals are needed, as chemical fertilizers and pesticides reduce
soil fertility and make plants more prone to disease. Monoculture
bananas are also more prone to pest attack and pests are increasingly
resistant to pesticides. Not only does this intensive chemical usage
have a negative effect on the environment, but they are a proven health
threat to workers and to the communities that surround them.
Pollution can also result from inadequate disposal of waste such as
rejected fruit and the plastic bags used to protect the bananas. An
array of drainage ditches all eventually empty into rivers and finally
the sea, polluting the surrounding land and waterways and contributing
to the destruction of coral reefs.
In organic agroforestry farming, on the other hand, the health of
the environment is recognized as being imperative to the success of
the farm. This system works in harmony with nature rather than destroying
it. Some farmers are even able to reclaim abandoned conventional plantations
and revert them to their natural state.
