Why was slash and burn farming important?

They allowed civilizations to be settled, populations to be sustained, and surpluses of food to be stored safely during all times of the year and in all climates. Slash and burn farming is also a relatively fast process that was more efficient than traditional hunting and gathering.

What are the disadvantages of slash and burn?

Deforestation is one of the most apparent disadvantages of using slash and burn techniques. Trees in particular are unable to replenish faster than the rate of destruction when slash and burn is practiced. Soil erosion is another concern caused by deforestation and poor farming techniques. Without trees, the soil is not anchored to the ground through root systems and therefore can lose its nutrients more quickly. Biodiversity and uniquely beautiful landscapes and ecosystems are also lost quickly when slash and burn methods are used. A final concern associated with slash and burn cultivation is the high amount of carbon being released into the air from the resulting fires, which has a negative impact on the health of humans and wildlife.

What is agriculture in the world?

Agriculture refers to the deliberate cultivation of large quantities of food in a specific area. The first agricultural practices were enabled through slash and burn farming techniques.

Agriculture provided a larger source of food than what could have been obtained in the wild. Settlers were nourished with a steady influx of food, even in harsh climates and during dry seasons that arose throughout the year.

Where is slash and burn farming practiced today?

Where is slash and burn agriculture practiced today? One of the primary locations where slash and burn agricultural techniques are still used is the Amazon rainforest. This dense ecosystem provides soil that is naturally nutrient-rich, but the heavy foliage provides even more nutrients when burned. The soil in the Amazon is highly leached, meaning that plants lose their nutrients as a result of high water runoff. Slash and burn farming has been effective at restoring nutrients to crops and other vegetation in the region. Other locations where slash and burn farming is currently practiced include the grasslands of central Africa and the forests of southeast Asia.

How does slash and burn affect agriculture?

Seeing that Madagascar depends a lot on subsistence farming, the environmental problems caused by slash and burn would harm the people greatly. As stated before, slash and burn causes soil erosion, which would cause desertification, and that would mean less farmland for the people to farm on. That itself would make a problem for Madagascar, economically and environmentally. About 1 to 2 percent of the forest is destroyed, and 80 to 90 percent of the land is burning each year. Only 10 percent of the country’s forests is left (Kreman). The farmers of Madagascar still continue to use slash and burn agriculture because that’s their only means of survival, since it is part of their culture and they do not know any other way to survive. Not only for slash and burn, the people of Madagascar depend on the forests for many other things as well, for hunting and for gathering. If this kind of agriculture continues, the forests will soon all disappear, leaving nothing left for the people to live off of (Kreman). Individuals, non-government organizations, and private businesses can take their own action to prevent the destruction of the lungs of the planet and to help those who practice sustainable farming, creating another alternative for them.

How can we reduce slash and burn?

Individuals around the world can donate money to those who practice slash and burn so they have money for an alternate method of farming. An example would be the Inga Alley Cropping System (Sitler). Inga Alley Cropping is a form of sustainable agriculture that was invented through scientific research. In this type of farming, trees are planted to simulate a rainforest environment and control the growth of weeds. The type of trees planted are called Inga trees, and it takes about two and a half years for them to be fully grown. After that, their wood can be used and prevent deforestation. As the crops are growing, the trees will also grow, which then means that when the next planting season arrives, the trees are ready to be cut again (Sitler). This is not the only method that can be used, with money farmers can also buy, or just use fertilizers from animals to grow crops. They can leave fertilizers at areas where they farmed on when they move into another plot of land, which will allow vegetation to grow back faster. Also with enough money, they can move on to different methods that is not limited to slash and burn. Only the individual can choose whether or not he or she wants to use which method of farming, so with the right resources, they can have a wider range of choices and therefore be able to choose to use a method of farming that isn’t harmful to themselves and to the environment.

What would happen if the land was overused?
