Explain slash and burn method of farming |
| Answer» Slash and burn agriculture is a method of growing food in which wild or forested land is clear cut and any remaining vegetation burned. The resulting layer of ash provides the newly-cleared land with a nutrient-rich layer to help fertilize crops. Slash-and-burn agriculture has been used in Central America and Mexico for thousands of years.Disadvantagrs:-\tLand 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.\tIts 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. | |
