WHY IT IS NECESSARY TO PRACTICE SLASH AND BURN AGRICULTURE IN HILL AND FORESTED AREA? EXPLAIN IT WITH EXAMPLE.
Answers
Explanation:
The resulting layer of ash provides the newly-cleared land with a nutrient-rich layer to help fertilize crops. However, under this method, land is only fertile for a couple of years before the nutrients are used up. Farmers must abandon the land, now degraded, and move to a new plot—clearing more forest in order to do so.
Slash-and-burn agriculture has been used in Central America and Mexico for thousands of years. But today, with more people than ever trying to survive in the midst of dwindling natural resources, its impact is particularly destructive and unsustainable.
There are many problems that result from this method of growing crops, including deforestation, a direct consequence of cutting down forests for crop land; loss of habitat and species; an increase in air pollution and the release of carbon into the atmosphere—which contributes to global climate change; and an increase in accidental fires.
