What is the term for clearing a land after a slash and burn?
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.
What was the use of slash and burn agriculture?
Thus, since Neolithic times, slash-and-burn agriculture has been widely used to clear land to make it suitable for crops and livestock.
When is slash and burn used in agriculture?
In slash-and-burn agriculture, forests are typically cut months before a dry season. The “slash” is permitted to dry and then burned in the following dry season. The resulting ash fertilizes the soil and the burned field is then planted at the beginning of the next rainy season with crops such as rice, maize, cassava, or other staples.
How does slash and burn work?
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. In Bangladesh and India, the practice is known as jhum or jhoom.
How long did it take for the Svedjebruk to regrow?
It was necessary to allow the former fields to regrow with forest for 10–30 years before repeating the cycle. As a result, the dwellings were often many kilometers from the fields. Furthermore, since the process was man-power intensive, extended families tended to work together and live in compact communities.
What is slash and burn?
Because the leached soil in many tropical regions, such as the Amazon, are nutritionally extremely poor, slash-and-burn is one of the only types of agriculture which can be practised in these areas. Slash-and-burn farmers typically plant a variety of crops, instead of a monoculture, and contribute to a higher biodiversity due to creating mosaic habitats. The general ecosystem is not harmed in traditional slash-and-burn, aside from a small temporary patch. Slash and burn agriculture may be thought of as a form of agroforestry.
What is slash and burn farming?
v. t. e. Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden.

This process is repeated over and over.
Why do farmers cultivate hillsides?
Often they have to cultivate hillsides as all the land lower down is used up, and as they progress up and up they are likely to meet another farmer at the top who has similarly worked his way up from the other side.
Why does the rainforest lose its fertility?
The soil loses its fertility because the richness of the rainforest is in the trees. As leaves fall or trees die everything is broken down by the soil’s organisms, nutrients are returned to the soil and the tree roots take them up again.
How many farmers are forced to eke out a living on these poor rainforest soils?
Maybe about 250 million farmers (they are not easy to count) are forced to eke out a living like that on these poor rainforest soils. By slashing and then burning the forest, these farmers can usually sustain themselves for only 2 consecutive years on the same patch of soil.
How often do farmers clear new plots?
Indeed quite often they clear a new plot every year. The soil then loses its fertility and the farmer is faced with either a daily walk of several miles to a new patch or, increasingly as the number of landless farmers grows, they may have to uproot their families to move.

Not only is this devastating the worlds remaining tropical forests (see “keeping carbon in the trees ” and “saving the rich diverse life of the rainforests”) while keeping the farmers in poverty , but it is also forcing many of them to abandon the land, and migrate to city slums in the hope of feeding their families. Life in the slums can be very hard indeed. There is not enough work available.
Can cash crops be guarded from thieves?

What is the act of burning biomass?
The act of burning Biomass to grow it is referred to as “swiddening”. It is the closest synonym to slash and bone and is frequently preferable to this term because it does not outline the acts of “ slashing” and “ burning”, which could lead to unfavorable stereotypes. However, in flesh and bone systems with short fallow periods, it is rarely used. Shifting cultivation implies that fields are moved from one area to another and that the land is not continuously cultivated. It includes both Slash-and-Burn and slash and mulch Systems, however, like with Swidden cultivation, it is rarely used in systems with short fallow, where cultivation is nearly permanent. It is also misleading because it implies that the land is abandoned and idle after a few years of agriculture, which is not always the case.

It has also been documented in societies where people maintain …
How does slash and burn work?
In the meantime, the farmer shifts to a field that has lain fallow for several years and removes the vegetation by cutting it down and burning it—hence the name “slash and burn.”. The ash from the burned vegetation adds another layer of nutrients to the soil, and that, along with the time resting, allows the soil to regenerate.

Is swidden agriculture bad?
Since the 1970s 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 2011) 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.
Is slash and burn a technique?
Slash and burn is a useful technique in some environments, but not in all.

Historically, slash-and-burn cultivation has been practiced throughout much of the world. Fire was already used by hunter-gatherers before the invention of agriculture, and still is in present times. Clearings created by the fire were made for many reasons, such as to provide new growth for game animals and to promote certain kinds of edible plants.
During the Neolithic Revolution, groups of hunter-gatherers domesticated various plants and anim…
Slash-and-burn fields are typically used and owned by a family until the soil is exhausted. At this point the ownership rights are abandoned, the family clears a new field, and trees and shrubs are permitted to grow on the former field. After a few decades, another family or clan may then use the land and claim usufructuary rights. In such a system there is typically no market in farmland, so land is not bought or sold on the open market and land rights are traditional.
Benefits and drawbacks
This system of agriculture provides millions of people with food and income. It has been ecologically sustainable for thousands of years. Because the leached soil in many tropical regions, such as the Amazon, are nutritionally extremely poor, slash-and-burn is one of the only types of agriculture which can be practiced in these areas. Slash-and-burn farmers typically plant a variety of crops, instead of a monoculture, and contribute to a higher biodiversity due to creati…
This type of agriculture is discouraged by many developmental or environmentalist organisations, with the main alternatives being promoted are switching to more intensive, permanent farming methods, or promoting a shift from farming to working in different, higher-paying industries altogether. Other organisations promote helping farmers achieve higher productivity by introducing new techniques.
