Slash-and-burn agriculture , also called fire-fallow cultivation , [1] is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile , as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move over to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. Slash-and-burn can be part of shifting cultivation , an agricultural system in which farmers routinely move from one cultivable area to another.

Slash-and-burn, also known as swidden agriculture or shifting cultivation, is an agricultural practice wherein natural vegetation such as forests and shrubs are cut down and burned to clear the land. Crops are then planted in the nutrient-rich soils left behind under the ashes. When that land becomes barren, a farmer shifts to another area with natural vegetation, and repeats that process again, according to Rainforest Saver. Ash from the burned woody vegetation contains calcium and magnesium, which lowers soil acidity, according to an Oregon State University study. Soil acidity hampers the yields of grain crops like maize. Slash and burn practices are also applied when large tracts of natural vegetation are to be cleared from the land to make way for the large-scale commercial cultivation of produce for exports, according to the Gale Encyclopedia of science.

Slash-and-burn agriculture , method of cultivation in which forests are burned and cleared for planting. Slash-and-burn agriculture is often used by tropical-forest root-crop farmers in various parts of the world and by dry-rice cultivators of the forested hill country of Southeast Asia. The ash provides some fertilization , and the plot is relatively free of weeds. After several years of cultivation, fertility declines and weeds increase. Traditionally, the area was left fallow and reverted to a secondary forest of bush.

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 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.

Slash and burn farming is a form of shifting agriculture where the natural vegetation is cut down and burned as a method of clearing the land for cultivation, and then, when the plot becomes infertile, the farmer moves to a new fresh plat and does the same again. This process is repeated over and over. The soil loses its fertility because the richness of the rainforest is in the trees.

Slash and Burn Agriculture

The cleared area following slash and burn, also known as swidden, is used for a relatively short period of time, and then left alone for a longer period of time so that vegetation can grow again. For this reason, this type of agriculture is also known as shifting cultivation. The plot is left alone for longer than it was cultivated, sometimes up to 10 or more years, to allow wild vegetation to grow on the plot of land. When vegetation has grown again, the slash and burn process may be repeated. Slash and burn agriculture is most often practiced in places where open land for farming is not readily available because of dense vegetation. Such farming is typically done within grasslands and rainforests.

Slash and burn agriculture—also known as swidden or shifting agriculture—is a traditional method of tending domesticated crops that involves the rotation of several plots of land in a planting cycle. It has also been documented in societies where people maintain a very broad diversity of food generation; that is, where people also hunt game, fish, and gather wild foods. Since the s or so, swidden agriculture has been described as both a bad practice, resulting in the progressive destruction of natural forests, and an excellent practice, as a refined method of forest preservation and guardianship. A recent study conducted on historical swidden agriculture in Indonesia Henley documented the historical attitudes of scholars towards slash and burn and then tested the assumptions based on more than a century of slash and burn agriculture. For example, if a swidden rotation is between 5 and 8 years, and the rainforest trees have a year cultivation cycle, then slash and burn represents one of what may be several elements resulting in deforestation.
