Slash-and-burn
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 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 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. Slash-and-burn is a type of shif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shifting Cultivation
Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. The period of time during which the field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow. This technique is often used in LEDCs (Less Economically Developed Countries) or LICs (Low Income Countries). In some areas, cultivators use a practice of slash-and-burn as one element of their farming cycle. Others employ land clearing without any burning, and some cultivators are purely migratory and do not use any cyclical method on a given plot. Sometimes no slashing at all is needed where regrowth is purely of grasses, an outcome not uncommon when soils are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jhum
The traditional shifting cultivation farming technique of indigenous communities and Bengalis in the Chittagong Hill Tracts in Bangladesh and nearby regions in Arunachal Pradesh, Mizoram, and Nagaland in India is known as jhum cultivation. Technique and crops In the month of January, the jhummias cut down the forest on the slope of the hill. Afterwards, they clean the land and dry the wood, bamboo and plants they have cut down in the sun. Later around March–April, the dried material is burnt and made suitable for jhum cultivation. Next, in the Bengali month of Baishakh and Jyeshtha (around May), jhummias dig holes in the burnt jhum soil and sow different types of seeds, including paddy, marfa, sweet pumpkin, cotton, sesame, and maize, which are cultivated several mon the later, depending on the particular crop. Jhum cultivation does not take place in some years due to drought. Yields are expected to be huge if there is no infestation of rats and other insects. Jhum cult ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Assarting
Assarting is the act of clearing forested lands for use in agriculture or other purposes. In English land law, it was illegal to assart any part of a royal forest without permission. This was the greatest trespass that could be committed in a forest, being more than a waste: while waste of the forest involves felling trees and shrubs, which can regrow, assarting involves completely uprooting all trees—the total extirpation of the forested area. The term ''assart'' was also used for a parcel of land assarted. Assart rents were those paid to the British Crown for the forest lands assarted. The etymology is from the French word ''essarter'' meaning to remove or grub out woodland. In northern England this is referred to as ''ridding''. Process In the Middle Ages, the land cleared was usually common land but after assarting, the space became privately used. The process took several forms. Usually it was done by one farmer who hacked out a clearing from the woodland, leaving a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic Revolution
The Neolithic Revolution, or the (First) Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible. These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops. Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene 11,700 years ago. It was the world's first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in the quality of human nutrition compared with that obtained previously from foraging. The Neolithic Revolution involved far more than the adoption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunter-gatherers
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups ...

Usufruct
Usufruct () is a limited real right (or ''in rem'' right) found in civil-law and mixed jurisdictions that unites the two property interests of ''usus'' and ''fructus'': * ''Usus'' (''use'') is the right to use or enjoy a thing possessed, directly and without altering it. * '' Fructus'' (''fruit'', in a figurative sense) is the right to derive profit from a thing possessed: for instance, by selling crops, leasing immovables or annexed movables, taxing for entry, and so on. A usufruct is either granted in severalty or held in common ownership, as long as the property is not damaged or destroyed. The third civilian property interest is ''abusus'' (literally ''abuse''), the right to alienate the thing possessed, either by consuming or destroying it (e.g., for profit), or by transferring it to someone else (e.g., sale, exchange, gift). Someone enjoying all three rights has full ownership. Generally, a usufruct is a system in which a person or group of persons uses the real property ...

Prehistory
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
