Glacier Growing
Glacier growing, artificial glaciation or glacier grafting, is a practice carried out in the Hindu Kush and Himalaya regions aimed at creating small new glaciers to increase water supply for crops and in some cases to sustain micro hydro power. In order to encourage the growth of a glacier local farmers acquire ice from naturally occurring glaciers, and carry it to high altitude areas where the ice is put inside a small cave dug out in a scree-slope. Along with the ice other ingredients such as water, salt, sawdust, wheat husks and charcoal are also placed at the site.Tveiten, I. (2007): ''Glacier Growing - A Local Response to Water Scarcity in Baltistan and Gilgit'', The Norwegian University of Life Sciences, Master of Science ThesisAbstract, pdf 65 Kb The use of glacier grafting is an old skill of the mountain farmers of Baltistan and Gilgit, where it is used for irrigation purposes since at least the 19th century.

Glacier Growing 1
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alizé Carrère
Alizé Carrère is a French-American climate researcher, filmmaker and science communicator. As a social scientist, she studies how humans adapt to changing physical environments, particularly with respect to climate change. Her academic research and filmmaking focus on the theme of human resilience to environmental change. In 2013, while attending McGill University in Montreal, Canada, she won a grant from National Geographic and she used the funds to travel to Madagascar to study how farmers were adapting to deforestation. Learning of farmers who were using erosional gullies as unique places to grow crops, she went on to study other ways that people were learning to adapt to profound environmental change. She received two additional grants from the National Geographic Society and filmmaker grants from The Redford Center and PBS to support the completion of a film series based on this work, titled ''ADAPTATION''. Carrère is the creator, producer and host of the series, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ladakh
Ladakh () is a region administered by India as a union territory which constitutes a part of the larger Kashmir region and has been the subject of dispute between India, Pakistan, and China since 1947. (subscription required) Quote: "Jammu and Kashmir, state of India, located in the northern part of the Indian subcontinent in the vicinity of the Karakoram and westernmost Himalayan mountain ranges. From 1947 to 2019, Ladakh was part of the Indian state of Jammu and Kashmir, which has been the subject of dispute between India, Pakistan, and China since the partition of the subcontinent in 1947." Quote: "Jammu and Kashmir: Territory in northwestern India, subject to a dispute between India and Pakistan. It has borders with Pakistan and China."

Chewang Norphel
Chewang Norphel ཚེ་དབང་ནོར་འཕེལ། (born 1935) is an Indian civil engineer from Ladakh, who has built 15 artificial glaciers. He has earned the nickname ''Ice Man''. Early life and career Coming from a middle-class family of Leh, Norphel went to Amar Singh College in Srinagar as a student of science. He completed a diploma course in civil engineering from Lucknow in 1960. In June 1960, he joined the rural development department of Jammu and Kashmir in Ladakh as a civil engineer. He retired in 1995. Artificial glaciers In 1996, Norphel joined the ''Leh Nutrition Project'', a non-governmental organisation, as project manager for watershed development. Norphel noticed a small stream had frozen solid under the shade of a group of poplar trees, though it flowed freely elsewhere in his yard. He realized the reason for this phenomenon: the flowing water was moving too quickly to freeze, while the sluggish trickle of water beneath the trees was sl ...

Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movement ...

Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Headwall
In physical geography and geology the headwall of a glacial cirque is its highest cliff. The term has been more broadly used to describe similar geomorphic features of non-glacial origin consisting of a concave depression with convergent slopes typically of 65 percent or greater forming the upper end of a drainage valley. In civil engineering, a headwall is a small retaining wall placed at the inlet or outlet of a stormwater pipe or culvert A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material. In the United Kingdom .... In medicine, a headwall is the wall at the head end of a hospital bedspace. The bed abuts this headwall perpendicularly, which is furnished with equipment such as regulators for supplemental oxygen, regulators for suction, suction canisters, connections for the call bell system, lighting, elect ...

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
