Ab-i Istada
Ab-i Istada ("standing water") is an endorheic salt lake in the Nawa District of Ghazni Province in Afghanistan. It lies in a large depression created by the Chaman Fault system in the southern foothills of the Hindu Kush, west of Ghazni. Description In modern times the lake has been reported to have a surface area of , although it dries out periodically. It is very shallow, not exceeding in depth. There are two small islands near the lake's southeastern shore, Loya ghundai () and Kuchney ghundai (). The water is highly alkaline and mass die-offs of freshwater fish from the Ghazni River sometimes occur. The main inflows into Ab-i Istada are the Ghazni, Sardeh and Nahara Rivers, which drain into it from the northeast. The watershed draining into the lake covers and was home to over 1.8 million people in 2003. Three sets of raised beaches surrounding the lake have been noted at , and above the normal lake level. At high water levels, the lake is known to overflow into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arghistan River
The Arghistan or Arghastan is a river in southern Afghanistan. It flows through Arghistan District and the provinces of Zabul and Kandahar. It is a tributary of the Dori River, a sub-tributary of the Helmand River. It flows for and has a basin area of . Geography The river rises in south-eastern Afghanistan, in the province of Zabul, near the border with Pakistan. Shortly after its start, the Arghastan takes a west-southwest course. It joins the Dori on the right bank, about south-west (downstream) of Kandahar. In its lower course, its waters are widely used to irrigate the oases of Kandahar, and its flow is greatly reduced. The average annual flow or module of the river is near the town of Kandahar.USGS Water Resources (1977) The Lora River (not to be confused with the Dori River, also known as the Lora River in its upper reaches) is a tributary from the northeast with its headwaters near Ab-i Istada Ab-i Istada ("standing water") is an endorheic salt lake in the Nawa D ...

Common Pochard
The common pochard (; ''Aythya ferina''), known simply as pochard in the United Kingdom, is a medium-sized diving duck in the family Anatidae. It is widespread across the Palearctic. It breeds primarily in the steppe regions of Scandinavia and Siberia, and winters further south and west. Taxonomy and systematics Swedish taxonomist Carl Linnaeus first assigned a scientific name to the common pochard in the tenth edition of his landmark treatise Systema Naturae; this was the first edition which included such names. He called the duck ''Anas ferina''. In 1822, German zoologist Friedrich Boie created the genus '' Aythya'' for various diving ducks, and moved the common pochard to that new genus. Uptake of ''Aythya'' as the genus for the common pochard was mixed for much of the next century, with some authors leaving the duck in the genus ''Anas'' or assigning it to various other now-defunct genera instead. The common pochard is considered a superspecies with the canvasback. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greylag Goose
The greylag goose (''Anser anser'') is a species of large goose in the waterfowl family Anatidae and the type species of the genus ''Anser (bird), Anser''. It has mottled and barred grey and white plumage and an orange beak and pink legs. A large bird, it measures between in length, with an average weight of . Its distribution is widespread, with birds from the north of its range in Europe and Asia often Bird migration, migrating southwards to spend the winter in warmer places, although many populations are resident, even in the north. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BCE. The genus name and specific epithet are from ''anser'', the Latin for "goose". In the USA, its name has been spelled "graylag". Greylag geese travel to their northerly breeding grounds in spring, nesting on moorlands, in marshes, around lakes and on coastal islands. They normally mate for life and nest on the ground among vegetation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Soviet–Afghan War
The Soviet–Afghan War took place in the Democratic Republic of Afghanistan from December 1979 to February 1989. Marking the beginning of the 46-year-long Afghan conflict, it saw the Soviet Union and the Armed Forces of the Democratic Republic of Afghanistan, Afghan military fight against the rebelling Afghan mujahideen, aided by Pakistan. While they were backed by various countries and organizations, the majority of the mujahideen's support came from Pakistan, the United States (as part of Operation Cyclone), the United Kingdom, China, Iran, and the Arab states of the Persian Gulf, in addition to a large influx of foreign fighters known as the Afghan Arabs. American and British involvement on the side of the mujahideen escalated the Cold War, ending a short period of relaxed Soviet Union–United States relations. Combat took place throughout the 1980s, mostly in the Afghan countryside, as most of the country's cities remained under Soviet control. The conflict resulted in the de ...

Greater Flamingo
The greater flamingo (''Phoenicopterus roseus'') is the most widespread and largest species of the flamingo family. Common in the Old World, they are found in Northern (coastal) and Sub-Saharan Africa, the Indian Subcontinent (south of the Himalayas), the Middle East, the Levant, the Persian Gulf, the Gulf of Aden, the Red Sea, and the Mediterranean countries of Southern Europe. Taxonomy The greater flamingo was described by Peter Simon Pallas in 1811. It was previously thought to be the same species as the American flamingo (''Phoenicopterus ruber''), but because of coloring differences of its head, neck, body, and bill, the two flamingos are now most commonly considered separate species. The greater flamingo has no subspecies and is therefore monotypic. Description The greater flamingo is the largest living species of flamingo, averaging tall and weighing . The largest male flamingos have been recorded to be up to tall and to weigh . Most of the plumage is pinkish-whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babur
Babur (; 14 February 148326 December 1530; born Zahīr ud-Dīn Muhammad) was the founder of the Mughal Empire in the Indian subcontinent. He was a descendant of Timur and Genghis Khan through his father and mother respectively. He was also given the posthumous name of ''Firdaws Makani'' ('Dwelling in Paradise'). Born in Andijan in the Fergana Valley (now in Uzbekistan), Babur was the eldest son of Umar Shaikh Mirza II (1456–1494, Timurid governor of Fergana from 1469 to 1494) and a great-great-great-grandson of Timur (1336–1405). Babur ascended the throne of Fergana in its capital Akhsikath in 1494 at the age of twelve and faced rebellion. He conquered Samarkand two years later, only to lose Fergana soon after. In his attempt to reconquer Fergana, he lost control of Samarkand. In 1501, his attempt to recapture both the regions failed when the Uzbek prince Muhammad Shaybani defeated him and founded the Khanate of Bukhara. In 1504, he conquered Kabul, which was un ...

Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to feed conversion ratio, convert the otherwise indigestible (by human digestive system, human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming. Farmers may employ many different strategies of grazing for crop yield, optimum production: grazing may be continuous, seasonal, or rotational grazing, rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site. Grazing has existed ...
