Lake Poopó
__NOTOC__ Lake Poopó ( es, Lago Poopó ) was a large saline lake in a shallow depression in the Altiplano Mountains in Oruro Department, Bolivia, at an altitude of approximately . Because the lake was long and wide (), it made up the eastern half of the department, known as a mining region in southwest Bolivia. The permanent part of the lake body covered approximately and it was the second-largest lake in the country. The lake received most of its water from the Desaguadero River, which flows from Lake Titicaca at the north end of the Altiplano. Since the lake lacked any major outlet and had a mean depth of less than , the surface area differed greatly seasonally. In 2002 the lake was designated as a site for conservation under the Ramsar Convention. By December 2015, the lake had completely dried up, leaving only a few marshy areas. Although the lake has dried up completely twice in the past, it does not appear that it will recover this time. Suggested causes of the declin ...

Altiplano
The Altiplano (Spanish for "high plain"), Collao (Quechua and Aymara: Qullaw, meaning "place of the Qulla") or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north-south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southwestern fringes lie in Chile. There are on the plateau several cities in each of these three nations, including El Alto, La Paz, Oruro, and Puno. The northeastern part of the Altiplano is more humid than the southwestern part, which has several salares (salt flats), due to its aridity. At the Bolivia–Peru border lies Lake Titicaca, the largest lake in South America. Farther south, in Bolivia, there was until recently a lake, Lake Poopó, but by December 2015 it had completely dried up, and was declared defunct. It is unclear whether that lake, which had been the second-largest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of Global Warming
The effects of climate change impact the physical environment, ecosystems and human societies. The environmental effects of climate change are broad and far-reaching. They affect the Effects of climate change on the water cycle, water cycle, Effects of climate change on oceans, oceans, Arctic sea ice decline, sea and land ice (Retreat of glaciers since 1850, glaciers), Sea level rise, sea level, as well as weather and Climate extremes, climate extreme events. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions. The regional changes vary: at high latitudes it is the average temperature that is increasing, while for the oceans and tropics it is in particular the rainfall and the water cycle where changes are observed. The magnitude of future impacts of climate change can be reduced by climate change mitigation and adaptation. Climate change has l ...

Endorheic Basin
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'wit ...

Salar De Uyuni
Salar de Uyuni (or "Salar de Tunupa") is the world's largest salt flat, or playa, at over in area. It is in the Daniel Campos Province in Potosí in southwest Bolivia, near the crest of the Andes at an elevation of above sea level. The Salar was formed as a result of transformations between several prehistoric lakes that existed around forty thousand years ago but had all evaporated over time. It is now covered by a few meters of salt crust, which has an extraordinary flatness with the average elevation variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. The large area, clear skies, and exceptional flatness of the surface make the Salar ideal for calibrating the altimeters of Earth observation satellites. Following rain, a thin layer of dead calm water transforms the flat into the world's largest mirror, across. The Salar serves as the major transport route a ...

Salar De Coipasa
__NOTOC__ Lago Coipasa or Salar de Coipasa is a lake in Sabaya Province, Oruro Department, Bolivia. At an elevation of 3657 m, its surface area is 806 km². It is on the western part of Altiplano, 20 km north of Salar de Uyuni and south of the main road linking Oruro and Huara (Chile). Lake Coipasa is a tectonic saline lake with a depth of 3.5 metres that is surrounded by the Coipasa salt flat (''Salar de Coipasa''), and the volcanic cone of Wila Pukarani. Thousands of flamingo Flamingos or flamingoes are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes.

Enclave
An enclave is a territory (or a small territory apart of a larger one) that is entirely surrounded by the territory of one other state or entity. Enclaves may also exist within territorial waters. ''Enclave'' is sometimes used improperly to denote a territory that is only partly surrounded by another state. The Vatican City and San Marino, both enclaved by Italy, and Lesotho, enclaved by South Africa, are completely enclaved sovereign states. An exclave is a portion of a state or district geographically separated from the main part by surrounding alien territory (of one or more states or districts etc). Many exclaves are also enclaves, but not all: an exclave can be surrounded by the territory of more than one state. The Azerbaijani exclave of Nakhchivan is an example of an exclave that is not an enclave, as it borders Armenia, Turkey and Iran. Semi-enclaves and semi-exclaves are areas that, except for possessing an unsurrounded sea border (a coastline contiguous with internat ...

Tiwanaku
Tiwanaku ( es, Tiahuanaco or ) is a Pre-Columbian archaeological site in western Bolivia near Lake Titicaca, about 70 kilometers from La Paz, and it is one of the largest sites in South America. Surface remains currently cover around 4 square kilometers and include decorated ceramics, monumental structures, and megalithic blocks. The site's population probably peaked around AD 800 with 10,000 to 20,000 people. The site was first recorded in written history in 1549 by Spanish conquistador Pedro Cieza de León while searching for the southern Inca capital of Qullasuyu. Jesuit chronicler of Peru Bernabé Cobo reported that Tiwanaku's name once was ''taypiqala'', which is Aymara meaning "stone in the center", alluding to the belief that it lay at the center of the world. The name by which Tiwanaku was known to its inhabitants may have been lost as they had no written language. Heggarty and Beresford-Jones suggest that the Puquina language is most likely to have been the language of T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caravan (travellers)
A caravan (from Persian ) or cafila (from Arabic ) is a group of people traveling together, often on a trade expedition. Caravans were used mainly in desert areas and throughout the Silk Road, where traveling in groups aided in defense against bandits as well as helped to improve economies of scale in trade. Some of the first caravans on the Silk Road were sent out by Emperor Wu of Han in the 2nd century BCE when this vast network of roads was 'born', and as China began exporting large quantities of silk and other goods west, particularly destined for the Roman Empire. Description In historical times, caravans connecting East Asia and Europe often carried luxurious and lucrative goods, such as silks or jewelry. Caravans could therefore require considerable investment and were a lucrative target for bandits. The profits from a successfully undertaken journey could be enormous, comparable to the later European spice trade. The luxurious goods brought by caravans attracted many ...

Llama
The llama (; ) (''Lama glama'') is a domesticated South American camelid, widely used as a List of meat animals, meat and pack animal by Inca empire, Andean cultures since the Pre-Columbian era. Llamas are social animals and live with others as a herd. Their wool is soft and contains only a small amount of lanolin. Llamas can learn simple tasks after a few repetitions. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 kilometre, km (5–8 miles). The name ''llama'' (in the past also spelled "lama" or "glama") was adopted by European colonization of the Americas, European settlers from Indigenous people in Peru, native Peruvians. The ancestors of llamas are thought to have originated from the Great Plains of North America about 40 million years ago, and subsequently migrated to South America about three million years ago during the Great American Interchange. By the end of the last Quaternary glaciation, ice age (10,000–12,000 years ago), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herder
A herder is a pastoral worker responsible for the care and management of a herd or flock of domestic animals, usually on open pasture. It is particularly associated with nomadic or transhumant management of stock, or with common land grazing. The work is often done either on foot or mounted. Depending on the type of animal being herd, the english language can give different professional names, for example, cowboy for cows, shepherd for sheep, or goatherd for goat. Terminology Herders may be distinguished by sex (''e.g.'', herdsman, herdswoman or herdboy) or by the type of livestock, for example camelherd, cowherd, duckherd, goatherd or shepherd. By country China Tibetan herding communities living in the Tibetan Plateau in the Sichuan Province of southwest China continued to graze herds on common lands even after the 1982 Household responsibility system. Several reasons have been given for the endurance of the traditional pastoral lifestyle: *complex topography preve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be genera ...
