Questions
1. the implication of the new system regarding who is involved in the farming
Select
A. Each year farmers begin by cutting down a hectare or so of rainforest using a machete. The cuttings are left on the ground to dry out and then burned, leaving the area clear to plant maize or beans. However, rainforest soils quickly lose their fertility when crops are grown on them, so after only one or two years, farmers have to move on to a new area of forest and start again. B. They are running out of locations to cultivate, and much of the more productive land has been acquired by plantation companies or converted to soy or banana monocultures. Farmers have no alternative but to cut short the fallow periods and return to land that hasn’t yet recovered. C. The solution he has come up with is a technique called Inga alley cropping, which imitates what rainforests do naturally: recycling nutrients back into the soil and creating an environment where grasses and weeds can’t flourish. D. One significant benefit of using the Inga system is that it encourages the participation of family members. E. No harmful agrochemicals are required because the Inga recycles soil nutrients, although farmers do need to replenish phosphorus in the soil by occasionally adding organic rock phosphate, which can be bought inexpensively in towns.
