What is slash and burn farming?

Slash and burn agriculture is a highly controversial and misunderstood practice. The practice has sometimes been associated with mass cutting, clearing and deforestation, but in fact “slash and burn” agriculture has a long standing history. The term slash and burn does sound harsh and destructive, but this farming technique, also known as shifting cultivation, can be extremely fruitful and sustainable if done correctly.The harsh cutting that is so often associated with slash and burn, is actually not at all the same practice. In the negative cases, large scale forests – often rainforests – are cut and cleared to make room for huge agricultural plots. These new farm lands are then usually planted with a single crop that is cultivated on that land until the soil is depleted of all viable nutrients. The process of shifting cultivation, however, is based on maintaining a sustainable, balanced form of farming that rotates and “shifts” within a given area, in order to allow the natural habitat to recuperate. Much like with seasons, there are various stages to this form of farming, and the process is not done in one fell swoop, cutting down entire forests and replanting them immediately.

How does slash and burn affect the environment?

One of the biggest perceived issues with slash and burn and shifting cultivation farming techniques is the negative impact on the environment. It is true that deforestation and uncontrolled slashing have had massive nad devastating impacts on ecosystems and habitats as well as greatly affected the environment at large. The removal of large expanses of trees and vegetation not only eliminates some of the world’s greatest carbon absorbers, but it has also led to erosion, soil nutrient depletion and left many areas completely barren wastelands. This drastic type of slashing is what is so often associated with slash and burn techniques, and has been argued against and ridiculed on a wide scale. However properly monitored and controlled shifting cultivation actually does not affect the environment in this way. One reason is, as mentioned above, the crops are rotated. This means that nutrients do not get depleted as rapidly or as thoroughly. When the same crop is planted in a given area season after season, the particular nutrients needed to nourish that plant are used at an increased rate. By rotating out plant crops, the soil has a chance to replenish – at least partially – between uses. Of course, for the nutrients to fully replenish, the soil does need down time, where no cultivation or agriculture occurs, which is why the most sustainable shifting agriculture involves rest periods where the ground is allowed to fallow and grow plants naturally.

What is shifting cultivation?

Shifting cultivation allows natural habitats to remain, and maintains biodiversity while still yielding crops. Sustainable slash and burn is more commonly known as shifting cultivation, meaning crops and farming rotate in a given area to maintain the soil and natural environment. Slash and burn agriculture is a highly controversial …

How does slash and burn work?

Once an area is established, trees, shrubs and large vegetation are all cut and left to dry out. After the plants have had ample time to dry, which usually takes a few days, intentional fires are set. The burning of the vegetation provides nutrients to the soil. When the trees and shrubs are burned, they break down nutrients in the dead plants, and make them more readily available to the soil. This process works much in the same way as adding fertilizer to soil before planting, except that the fertilizer in this case is natural, and coming directly from the burned plants that were already growing in that area.

How many seasons does shifting cultivation take?

Part of the shifting aspect of shifting cultivation, which is not found in other types of slashing, is that these crops are usually only planted for two growing seasons. This way, the plants benefit from the nutrient rich soil, without allowing the area to be over-used or completely depleted.

Why is shifting cultivation important?

The process of shifting cultivation, however, is based on maintaining a sustainable, balanced form of farming that rotates and “shifts” within a given area, in order to allow the natural habitat to recuperate.

What is the catch with slash and burn agriculture?

The catch with slash and burn agriculture is that the fertilization from the burning has only a temporary effect. As the crops grow, they uptake the nutrients that were placed into the soil by the burning. The crops in the first growing season have full access to all of the nutrients, but the crops in subsequent growing seasons only have access …

What is slash and burn?

Slash & burn agriculture is a form of agriculture that has been practiced in places all around the world for centuries. The process starts with an area of land that is covered with foliage such as trees and shrubs. The foliage is in the way of any would-be agriculture and so it must be cleared before anything can be planted.

Why is the slash and burn process important?

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,

Why do crops rotate?

They might be able to rotate crops, if different crops will remove different nutrients from the soil and also put other nutrients back into the soil. (For example, grain crops like wheat and maize take nitrogen from the soil, whereas legume crops like beans and peanuts put nitrogen into the soil.)

Why is there not enough land for farmers?

In practice today, there very often is not enough land per farmer. This happens when there is a lot of population growth in an area. It means that a given section of land does not have enough time to regrows fully before a farmer needs it again. As a result, more and more land is cleared. This can contribute to major deforestation across broad regions. It can also put farmers and their dependents into poverty, as they lack access to adequate land to grow the food that they depend on. Finally, it can force people out of the farming business. Some of these people may seek alternative employment within the area, and others will migrate. Often these people will migrate to cities, moving into slums and seeking whatever work they can find to get by.

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.
