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 cu ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mizoram
Mizoram () is a state in Northeast India, with Aizawl as its seat of government and capital city. The name of the state is derived from "Mizo", the self-described name of the native inhabitants, and "Ram", which in the Mizo language means "land." Thus "Mizo-ram" means "land of the Mizos". Within India's northeast region, it is the southernmost landlocked state, sharing borders with three of the Seven Sister States, namely Tripura, Assam and Manipur. The state also shares a border with the neighbouring countries of Bangladesh and Myanmar. Like several other northeastern states of India, Mizoram was previously part of Assam until 1972, when it was carved out as a Union Territory. In 1986 the Indian Parliament adopted the 53rd amendment of the Indian Constitution, which allowed for the creation of the State of Mizoram on 20 February 1987, as India's 23rd state. According to a 2011 census, in that year Mizoram's population was 1,091,014. It is the 2nd least populous state in ... [...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] |

Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and corn sy ...

Bengalis
Bengalis (singular Bengali bn, বাঙ্গালী/বাঙালি ), also rendered as Bangalee or the Bengali people, are an Indo-Aryan ethnolinguistic group originating from and culturally affiliated with the Bengal region of South Asia. The current population is divided between the independent country Bangladesh and the Indian states of West Bengal, Tripura and parts of Assam, Meghalaya and Manipur. Most of them speak Bengali, a language from the Indo-Aryan language family. Bengalis are the third-largest ethnic group in the world, after the Han Chinese and Arabs. Thus, they are the largest ethnic group within the Indo-Europeans and the largest ethnic group in South Asia. Apart from Bangladesh and the Indian states of West Bengal, Tripura, Manipur, and Assam's Barak Valley, Bengali-majority populations also reside in India's union territory of Andaman and Nicobar Islands, with significant populations in the Indian states of Arunachal Pradesh, Delhi, Odi ...

Sangu Matamuhari or Sangu Wildlife Sanctuary is a wildlife sanctuary—IUCN category II (habitat/species management area)—situated in Bandarban District, Chittagong Division, Bangladesh. It is part of the Sangu reserve forest. It is under the Lama Forest Division of the Bangladesh Forest Department. Its bio-ecological zone is in Chittagong Hills and Chittagong Hill Tracts. It houses Bangladesh's richest wildlife resource after Sunderbans.

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 ...

Kaptai Dam
Kaptai Dam ( bn, কাপ্তাই বাঁধ) is on the Karnaphuli River at Kaptai, upstream from Chittagong in Rangamati District, Bangladesh. It is an earth-fill embankment dam with a reservoir (known as Kaptai Lake) water storage capacity of . The primary purpose of the dam and reservoir was to generate hydroelectric power. Construction was completed in 1962, in then-East Pakistan. The generators in the Karnafuli Hydroelectric Power Station were commissioned between 1962 and 1988. It is the only hydroelectric power station in Bangladesh. History A brief reconnaissance occurred in 1906 when the Karnafuli Hydropower Station was first contemplated. A second study was carried out in 1923. In 1946, E. A. Moore recommended the proposed project at Barkal about 65 kilometres upstream of present dam site at Kaptai. In 1950, the Marz Rendal Vatten Consulting Engineers suggested a site at Chilardak, about 45 kilometres upstream of Kaptai. In 1951, the government engineers pr ...
