It is subsistence agriculture that typically uses little technology or other tools. It is typically part of shifting cultivation agriculture, and of transhumance livestock herding.
Slash-and-burn techniques are used by between and million people worldwide. The technique is not sustainable beyond a certain population density because, without the trees, the soil quality soon becomes too poor to support crops.
The farmers have to move on to a virgin forest and repeat the process. Methods such as Inga alley farming have been proposed as an alternative to this ecological destruction. During the Neolithic Revolution, which included agricultural advancements, groups of hunter-gatherers domesticated various plants and animals, permitting them to settle down and practice agriculture which provides more nutrition per hectare than hunting and gathering.
This happened in the river valleys of Egypt and Mesopotamia. Due to this decrease in food from hunting as human populations increased, agriculture became more important. Some groups could easily plant their seeds in open fields along river valleys, but others had forests blocking their farming land.
In this context, humans used slash-and-burn agriculture to clear more land, and make it suitable for their plants and animals.
Thus, since Neolithic times, slash-and-burn techniques have been widely used for converting forests into crop fields and pasture. Clearings created by fire were made for many reasons, such as to draw game animals and to promote certain kinds of edible plants such as berries.
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, and land is not bought and sold in the open market.
The resulting ash fertilizes the soil, and the burned field is then planted at the beginning of the next rainy season with crop such as upland rice, maize, cassava, or other staple crop. Most of this work is typically done by hand, using machetes, axes, hoes, and other such basic tools.
The ashes that come from the trees would also help farmers, for it provides nutrients for farming. For example, slash-and-burn agriculture was initially practiced by European pioneers in North America like Daniel Boone and his family who cleared land in the Appalachian Mountains in the late 18th and early 19th Centuries.
This system involves clearing a piece of land by setting fire or clear felling and using the area for growing crops of agricultural importance such as upland rice, vegetables or fruits. After a few cycles, the land loses fertility and a new area is chosen.
Jhum cultivation is most practiced on the slopes of hills in thickly forested landscapes. The cultivators cut the treetops to allow sunlight to reach the land. They burn all the trees and grasses for clean and fresh soil.We will write a custom essay sample on Agriculture and Current Deforestation Practices Essay Sample specifically for you We will write a custom essay sample on Agriculture and Current Deforestation Practices Essay Sample specifically for you.
