Question

what is Slash and Burn agriculture

Answer 1

Slash and burn agriculture is a widely used 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. 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 inCentral 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, includingdeforestation, 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. Slash and burn agriculture also results in significant soil erosion and accompanying landslides, water contamination, and/or dust clouds, as without trees and vegetation and their root systems, soil washes away during heavy rains and blows away during droughts.

EcoLogic helps local people adopt sustainable methods of agriculture, includingalley-cropping, an agroforestry technique where people plant food crops alongside trees. We also promote planting a diversity of food crops, the creation of buffer zones of native trees around existing forest, and the reclamation of degraded land through reforestation and other practices.

Answer 2

SLASH N BURN AGRICULTURE IS ANOTHER NAME OF PRIMITIVE SUBSISTENCE FARMING..

PEOPLE DEPEND ON PRIMITIVE TOOLS LIKE DAO AND CULTIVATE CROP FOR SUSTENANCE OF FAMILY ON SMALL FIELD.

WHEN SOIL LOSES ITS FERTILITY THEY MOVE TO FRESH LAND.

THIS ALLOWS NATURAL FERTILITY OF SOIL TO REPLENISH...
