What is the definition of slash and burn farming?
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.
What does slash mean in agriculture Dictionary?
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.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 …
Why is slash-and-burn farming no longer sustainable?
Slash-and-burn causes temporary deforestation. Ashes from the burnt trees help farmers by providing nutrients for the soil. In low density of human population this approach is very sustainable but the technique is not scalable for large human populations.
Is slash and burn agriculture subsistence?
Slash and burn is a subsistence farming method used by millions of families in the tropics as their only known means of producing food. Families cut down and burn a patch of forest in order to create an area of fertile soil on which they can grow their food.
Why slash and burn is good?
It is burned here because the burning process releases nutrients which then fertilize the soil. So, the slash and burn process successfully clears land for agriculture and introduces fertilizing nutrients into the soil, leaving it in excellent condition to grow crops.
What are sustainable methods of agriculture that can replace slash and burn?
Another option is to combine agriculture with animal husbandry. The waste from the animals can be used as fertilizer to sustain agriculture. The use of fertilizer both natural and artificial sources could replace the use of burning the trees to create fertile fields in the forest for agriculture.
Why is slash and burn agriculture important?
The slash and burn agriculture method makes full use of the versatility of soil and crops to ensure that farmers are able to conduct agriculture in inhospitable regions. Although this is not the ideal long term solution to the food crisis and farmer instability, it at least allows a generation of farmers to stay afloat as alternatives arise to solve the problems.
What is slash and burn farming?
Slash and burn farming or slash and burn agriculture is the process of shifting agriculture by clearing a piece of land for cultivation. Here, the natural vegetation of the land is cut down and eventually burned in order to make space for agricultural crops. Once this plot of land becomes infertile, the entire process is shifted to a new plot …
What are the positives and negatives of slash and burn farming?
The following are some of the positives of slash and burn agriculture: It allows farming to be conducted in regions that is normally not associated with this practice. It helps to temporarily boost the fertility of a region.
How to do slash and burn?
The following steps are often used to conduct slash and burn agriculture by farmers: 1 They prepare the field by first cutting down pre-existing vegetation. Sometimes, plants that offer food or timber may be left alone in this practice 2 The vegetation that has been cut down is allowed to dry until the rainy season is about to reach its height 3 The plot of land is then burned to ensure that all vegetation has been removed and to drive away the various pests of a region. This helps to provide a burst of nutrition to the soil 4 A new batch of crops is planted in the ashes left after the previous forest has been burnt. This allows the crops to absorb the new-found nutrition from the soil
Why do farmers plant new crops in the ashes?
A new batch of crops is planted in the ashes left after the previous forest has been burnt. This allows the crops to absorb the new-found nutrition from the soil. Farmers conduct cultivation on the new plot for a few years until the soil has lost all its fertility.
What happens when vegetation is burned down?

Where is slash and burn used?
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.
What happens after a year of cultivation?
After several years of cultivation, fertility declines and weeds increase. Traditionally, the area was left fallow and reverted to a secondary forest of bush. Cultivation would then shift to a new plot. After about a decade the old site could be reused.
Does slash and burn produce carbon dioxide?

Where is slash and burn farming practiced?
These regions include central Africa, northern South America, and Southeast Asia. Such farming is typically done within grasslands and rainforests .
How long has slash and burn been around?
Humans have practiced this method for about 12,000 years, ever since the transition known as the Neolithic Revolution—the time when humans stopped hunting and gathering and started to stay put and grow crops. Today, between 200 and 500 million people use slash and burn agriculture, roughly 7% of the world’s population.
What are the negative aspects of slash and burn?
They include: Deforestation: When practiced by large populations, or when fields are not given sufficient time for vegetation to grow back, there is a temporary or permanent loss of forest cover.
Why is slash and burn important?
Slash and burn allows people to farm in places where it usually is not possible because of dense vegetation, soil infertility, low soil nutrient content, uncontrollable pests, or other reasons .
How to slash and burn?
Generally, the following steps are taken in slash and burn agriculture: Prepare the field by cutting down vegetation; plants that provide food or timber may be left standing. The downed vegetation is allowed to dry until just before the rainiest part of the year to ensure an effective burn.
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 is slash and burn farming?
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. The farmer plants crops in a field for one or two seasons and then lets the field lie fallow for several seasons.
What is slash and burn?
For example, if a swidden rotation is between 5 and 8 years, and the rainforest trees have a 200-700 year cultivation cycle, then slash and burn represents one of what may be several elements resulting in deforestation. Slash and burn is a useful technique in some environments, but not in all. A special issue of “Human Ecology” suggests …
What is the best way to slash and burn?
The Best Conditions for Slash and Burn Agriculture. Slash and burn agriculture works best in low-intensity farming situations when the farmer has plenty of land that he or she can afford to let lay fallow, and it works best when crops are rotated to assist in restoring the nutrients. 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. A special issue of “Human Ecology” suggests that the creation of global markets is pushing farmers to replace their swidden plots with permanent fields. Alternatively, when farmers have access to off-farm income, swidden agriculture is maintained as a complement …
What is slash and burn?
“Slash-and-burn” is “swidden agriculture” which is “shifting cultivation” . It supports approximately 500 million people located primarily in the uplands of South East Asia, most of which are poor and dependent on natural resources for survival . Essentially, it’s the practice whereby rural farmers clear an area of forest through means of slashing and burning. The area is then used for cultivation (growing crops). Cultivation lasts for around 1-3 years, and then the field is left fallow for 5 to 20 years [1, 4, 5].
