TPLF
The Tigray People's Liberation Front (TPLF; ), also known as the Tigrayan People's Liberation Front, is a left-wing ethnic nationalist, paramilitary group, and the former ruling party of Ethiopia. It was classified as a terrorist organization by the Ethiopian government during the Tigray War until its removal from the list in 2023. In older and less formal texts and speech it is known as Woyane () or Weyané (). The TPLF was founded on February 18, 1975, in Dedebit, Tigray. Within 16 years, it grew from about a dozen men to become the most powerful armed liberation movement in Ethiopia. Unlike the Eritrean or Somali liberation fronts at the time, the TPLF did not seek independence from the Ethiopian state; instead, it aimed to overthrow the central government and implement its own version of the Ethiopian revolution. From 1989 to 2018, it led a political coalition, the Ethiopian People's Revolutionary Democratic Front (EPRDF). It fought a 15-year-long war against the Der ...

Chini (reservoir)
Chini is a small reservoir located in Melfa (Dogu’a Tembien ''woreda'', Tigray Region, Ethiopia). The 151-metres long earthen dam that holds the reservoir was built in 1993 by the Relief Society of Tigray. It was mainly constructed for purpose of livestock watering. The catchment of the reservoir is 1.86 km² large, with a perimeter of 5.15 km and a length of 1800 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is composed of Ashangi Basalts. Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in .... Actually, in the wider surrounding of the reservoir, both upstream and downstream the level of the watertab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Tembien
Tembien (Tigrinya language, Tigrigna: ተምቤን) is a historic region in Tigray Region and former provinces of Ethiopia. It is a mountainous area of that country. During the reforms in 1994–95, the old provinces were replaced with regions of Ethiopia, regions, zones of Ethiopia, zones and woredas. The area of the former province is now split over the woredas of Dogua Tembien and Kola Tembien. It was located east of the Semien Province, north of Abergele (woreda), Abergele, and on the east, it was bordered by the Enderta Province. The original capital of the province was Melfa (Dogu'a Tembien), Melfa, west of the current town of Hagere Selam (Degua Tembien), Hagere Selam; later on Abiy Addi, nowadays located in Kola Tembien (''Lower Tembien''), became the capital. The region reached a highpoint in the Tsatsen mountains at 2828 meters above sea level, just south of Hagere Selam. Prehistory Tembien holds numerous prehistoric sites, which have been dated to the Middle Stone A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cropping System
The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system. Historically, cropping systems have been designed to maximise yield, but modern agriculture is increasingly concerned with promoting environmental sustainability in cropping systems. Manish mandavi B.Tech student Crop choice Crop choice is central to any cropping system. In evaluating whether a given crop will be planted, a farmer must consider its profitability, adaptability to changing conditions, resistance to disease, and requirement for specific technologies during growth or harvesting. They must also consider the prevailing environmental conditions on their farm, and how the crop will fit in with other elements of their production system. Crop organisation and rotation Monoculture is the practice of growing a single crop in a given area, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farming System
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than .

Farmland
Agricultural land is typically land ''devoted to'' agriculture, the systematic and controlled use of other forms of lifeparticularly the rearing of livestock and production of cropsto produce food for humans. It is generally synonymous with both farmland or cropland, as well as pasture or rangeland. The United Nations Food and Agriculture Organization (FAO) and others following its definitions, however, also use ''agricultural land'' or as a term of art, where it means the collection of: * '' arable land'' (also known as ''cropland''): here redefined to refer to land producing crops requiring annual replanting or fallowland or pasture used for such crops within any five-year period * '' permanent cropland'': land producing crops which do not require annual replanting * ''permanent pastures'': natural or artificial grasslands and shrublands able to be used for grazing livestock This sense of "agricultural land" thus includes a great deal of land not devoted to agricultural use ...

Non-timber Forest Product
Non-timber forest products (NTFPs) are useful foods, substances, materials and/or commodities obtained from forests other than timber. Harvest ranges from wild collection to farming. They typically include game animals, fur-bearers, nuts, seeds, berries, mushrooms, oils, sap, foliage, pollarding, medicinal plants, peat, mast, fuelwood, fish, insects, spices, and forage. Overlapping concepts include non-wood forest products (NWFPs), wild forest products, minor forest produce, special, minor, alternative and secondary forest products – for further distinctions see the definition section below Research on NTFPs has focused on their ability to be produced as commodities for rural incomes and markets, as an expression of traditional knowledge or as a livelihood option for rural household needs, as a key component of sustainable forest management and conservation strategies, and for their important role in improving dietary diversity and providing nutritious food, particul ...

Carbon Sequestration
Carbon sequestration is the process of storing carbon in a carbon pool. It plays a crucial role in Climate change mitigation, limiting climate change by reducing the amount of Carbon dioxide in Earth's atmosphere, carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called ''biosequestration'') and geologic. Biologic carbon sequestration is a naturally occurring process as part of the carbon cycle. Humans can enhance it through deliberate actions and use of technology. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These processes can be accelerated for example through changes in land use and agricultural practices, called carbon farming. Artificial processes have also been devised to produce similar effects. This approach is called carbon capture and storage. It involves using technology to capture and sequester (store) that is produced from human activities under ...

Sediment
Sediment is a solid material that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently sediment transport, transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension (chemistry), suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial, fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and stream channel, river channel deposits are examples of fluvial transport and deposition (geology), deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Infiltration
Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. The infiltration capacity decreases as the soil moisture content of soils surface layers increases. If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier. Infiltrometers, parameters and rainfall simulators are all devices that can be used to measure infiltration rates. Infiltration is caused by multiple factors including; gravity, capillary forces, adsorption, and osmosis. Many soil characteristics can also play a role in determining the rate at which infiltration occurs. Factors that affect infiltration Precipitation Precipitation can impact infiltration in many ways.

Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
