107-586: Sumapaz Páramo was considered a sacred place for the Muisca indigenous people. It was associated with the divine forces of creation and the origin of mankind , a domain where humans were not supposed to enter. During the 16th century, German adventurer and conquistador Nikolaus Federmann conducted an expedition crossing the Sumapaz, searching for El Dorado mythic treasure, with heavy casualties, where men, both Spaniards and indigenous, and horses, died of cold. The place

214-408: A drop in the ground surface. In unconsolidated aquifers, groundwater is produced from pore spaces between particles of gravel, sand, and silt. If the aquifer is confined by low-permeability layers, the reduced water pressure in the sand and gravel causes slow drainage of water from the adjoining confining layers. If these confining layers are composed of compressible silt or clay, the loss of water to

321-402: A former lake bed, has experienced rates of subsidence of up to 40 centimetres (1 foot 4 inches) per year. For coastal cities, subsidence can increase the risk of other environmental issues, such as sea level rise . For example, Bangkok is expected to have 5.138 million people exposed to coastal flooding by 2070 because of these combining factors. If the surface water source

428-1070: A global level, although priority chemicals will vary by country. There is a lot of heterogeneity of hydrogeologic properties. For this reason, salinity of groundwater is often highly variable over space. This contributes to highly variable groundwater security risks even within a specific region. Salinity in groundwater makes the water unpalatable and unusable and often occurs in coastal areas, for example in Bangladesh and East and West Africa. Municipal and industrial water supplies are provided through large wells. Multiple wells for one water supply source are termed "wellfields", which may withdraw water from confined or unconfined aquifers. Using groundwater from deep, confined aquifers provides more protection from surface water contamination. Some wells, termed "collector wells", are specifically designed to induce infiltration of surface (usually river) water. Aquifers that provide sustainable fresh groundwater to urban areas and for agricultural irrigation are typically close to

535-408: A home and then returned to the ground in another well. During cold seasons, because it is relatively warm, the water can be used in the same way as a source of heat for heat pumps that is much more efficient than using air. Groundwater makes up about thirty percent of the world's fresh water supply, which is about 0.76% of the entire world's water, including oceans and permanent ice. About 99% of

642-519: A long time without severe consequences. Nevertheless, over the long term the average rate of seepage above a groundwater source is the upper bound for average consumption of water from that source. Groundwater is naturally replenished by surface water from precipitation , streams , and rivers when this recharge reaches the water table. Groundwater can be a long-term ' reservoir ' of the natural water cycle (with residence times from days to millennia), as opposed to short-term water reservoirs like

749-506: A long-term 3-decade research of the vegetal communities, and Thomas van der Hammen . Sumapaz Páramo has an inhospitable, cold climate with temperatures averaging below 10 °C (50 °F).(ranging from −10 °C to 17 °C) with quick changes from short periods of warm climate to freezing cold. The average altitude oscillates between 3500 and 4000 m. AMSL . The highest point is the Nevado del Sumapaz peak (4306 m AMSL). The precipitation

856-646: A major festival where ritual offerings were made. It was the only day of the year when the zaque showed his face, as he was considered a descendant of the Sun god. The Muisca mythology is well documented. Many of the writers who contributed to the Chronicles of the West Indies were based in Bogotá. They recorded many of the myths as they were interested in the traditions and culture of the conquered people. The Muisca territory became

963-426: A permanent threat as rivals of the zaque of Hunza , especially for the possession of the salt mines of Zipaquirá , Nemocón and Tausa . The Muisca people were organized in a confederation that was a loose union of states that each retained sovereignty. The confederation was not a kingdom, as there was no absolute monarch, nor was it an empire , because it did not dominate other ethnic groups or peoples. It

1070-705: A permanently reduced capacity to hold water. The city of New Orleans, Louisiana is actually below sea level today, and its subsidence is partly caused by removal of groundwater from the various aquifer/aquitard systems beneath it. In the first half of the 20th century, the San Joaquin Valley experienced significant subsidence , in some places up to 8.5 metres (28 feet) due to groundwater removal. Cities on river deltas, including Venice in Italy, and Bangkok in Thailand, have experienced surface subsidence; Mexico City, built on

1177-499: A popular sport of Colombia. Also important were matches of wrestling . The winner received a finely woven cotton blanket from the chief and was qualified as a guecha warrior . Muisca priests were educated from childhood and led the main religious ceremonies. Only the priests could enter the temples. Besides the religious activities, the priests had much influence in the lives of the people, giving counsel in matters of farming or war. The religion originally included human sacrifice , but

1284-513: A territory roughly covering modern southern and northeastern Boyacá and southern Santander ; the psihipqua , centered in Muyquytá and encompassing most of modern Cundinamarca , the western Llanos ; and the iraca , religious ruler of Suamox and modern northeastern Boyacá and southwestern Santander. The territory of the Muisca spanned an area of around 25,000 km (9,700 sq mi) from

1391-399: Is a highly useful and often abundant resource. Most land areas on Earth have some form of aquifer underlying them, sometimes at significant depths. In some cases, these aquifers are rapidly being depleted by the human population. Such over-use, over-abstraction or overdraft can cause major problems to human users and to the environment. The most evident problem (as far as human groundwater use

1498-465: Is about 700–1000 mm/year. The rainy season lasts almost the entire year, except from December to February, when the sunlight reaches a peak, with intense ultraviolet radiation (adaptations such as white, glassy coloration help the local plants to survive). The humidity is usually high, (from 50 to 90%), and the ground remains soaked, and covered by shallow bodies of water and sticky mud, often covered with dense, flat vegetation difficult to spot by

1605-528: Is also often withdrawn for agricultural , municipal , and industrial use by constructing and operating extraction wells . The study of the distribution and movement of groundwater is hydrogeology , also called groundwater hydrology . Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture , permafrost (frozen soil), immobile water in very low permeability bedrock , and deep geothermal or oil formation water. Groundwater

1712-466: Is also subject to substantial evaporation, a groundwater source may become saline . This situation can occur naturally under endorheic bodies of water, or artificially under irrigated farmland. In coastal areas, human use of a groundwater source may cause the direction of seepage to ocean to reverse which can also cause soil salinization . As water moves through the landscape, it collects soluble salts, mainly sodium chloride . Where such water enters

1819-632: Is an additional water source that was not used previously. First, flood mitigation schemes, intended to protect infrastructure built on floodplains, have had the unintended consequence of reducing aquifer recharge associated with natural flooding. Second, prolonged depletion of groundwater in extensive aquifers can result in land subsidence , with associated infrastructure damage – as well as, third, saline intrusion . Fourth, draining acid sulphate soils, often found in low-lying coastal plains, can result in acidification and pollution of formerly freshwater and estuarine streams. Groundwater

1926-417: Is concerned) is a lowering of the water table beyond the reach of existing wells. As a consequence, wells must be drilled deeper to reach the groundwater; in some places (e.g., California , Texas , and India ) the water table has dropped hundreds of feet because of extensive well pumping. The GRACE satellites have collected data that demonstrates 21 of Earth's 37 major aquifers are undergoing depletion. In

2033-412: Is fresh water located in the subsurface pore space of soil and rocks . It is also water that is flowing within aquifers below the water table . Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water , and deep groundwater in an aquifer (called " fossil water " if it infiltrated into the ground millennia ago ). Groundwater can be thought of in

2140-684: Is hard to compare the Muisca Confederation with other American civilizations, such as the Aztec or the Inca empires as it was more similar to a confederation of states, such as the Achaean League . The Muisca Confederation was one of the biggest and best-organized confederations of tribes on the South American continent. Every tribe within the confederation was ruled by a chief or a cacique . Most of

2247-427: Is hypothesized to provide lubrication that can possibly influence the movement of faults . It is likely that much of Earth 's subsurface contains some water, which may be mixed with other fluids in some instances. Groundwater is often cheaper, more convenient and less vulnerable to pollution than surface water . Therefore, it is commonly used for public drinking water supplies. For example, groundwater provides

2354-545: Is less visible and more difficult to clean up than pollution in rivers and lakes. Groundwater pollution most often results from improper disposal of wastes on land. Major sources include industrial and household chemicals and garbage landfills , excessive fertilizers and pesticides used in agriculture, industrial waste lagoons, tailings and process wastewater from mines, industrial fracking , oil field brine pits, leaking underground oil storage tanks and pipelines, sewage sludge and septic systems . Additionally, groundwater

2461-574: Is mainly derived from mythological contexts, but thanks to the Chronicles of the West Indies we do have descriptions of the final period of Muisca history, prior to Spanish arrival. Excavations in the Altiplano Cundiboyacense (the highlands of Cundinamarca and Boyacá departments) show evidence of human activity since the Archaic stage at the beginning of the Holocene era. Colombia has one of

2568-468: Is rapidly increasing with population growth, while climate change is imposing additional stress on water resources and raising the probability of severe drought occurrence. The anthropogenic effects on groundwater resources are mainly due to groundwater pumping and the indirect effects of irrigation and land use changes. Groundwater plays a central role in sustaining water supplies and livelihoods in sub-Saharan Africa . In some cases, groundwater

2675-553: Is susceptible to saltwater intrusion in coastal areas and can cause land subsidence when extracted unsustainably, leading to sinking cities (like Bangkok ) and loss in elevation (such as the multiple meters lost in the Central Valley of California ). These issues are made more complicated by sea level rise and other effects of climate change , particularly those on the water cycle . Earth's axial tilt has shifted 31 inches because of human groundwater pumping. Groundwater

2782-400: Is the most accessed source of freshwater around the world, including as drinking water , irrigation , and manufacturing . Groundwater accounts for about half of the world's drinking water, 40% of its irrigation water, and a third of water for industrial purposes. Another estimate stated that globally groundwater accounts for about one third of all water withdrawals , and surface water for

2889-452: Is used for irrigation. Occasionally, sedimentary or "fossil" aquifers are used to provide irrigation and drinking water to urban areas. In Libya, for example, Muammar Gaddafi's Great Manmade River project has pumped large amounts of groundwater from aquifers beneath the Sahara to populous areas near the coast. Though this has saved Libya money over the alternative, seawater desalination,

Other animals described are: Little Red Brocket Deer , tapir , coati , golden eagle , torrent duck , Páramo duck (Anas georgica). An introduced species in the waterbodies is the rainbow trout . Although the soil and climate are adverse for agriculture and other economic activities, human settlements do exist in

3103-462: The zipa , had its capital at Bacatá (now Bogotá ). This southern polity included the majority of the Muisca population and held greater economic power. The northern territory was ruled by the zaque , and had its capital in Hunza, known today as Tunja . Although both areas had common political relations and affinities and belonged to the same tribal nation, there were still rivalries between them. Among

3210-788: The Andes of the north of South America . Their political and administrative organization enabled them to form a compact cultural unity with great discipline. In Spanish, it is called cultura muisca The contributions of the Muisca culture to the Colombian national identity have been many. Pre-Columbian Muisca patterns appear in various seals of modern municipalities located on the Altiplano Cundiboyacense , for instance Sopó and Guatavita , Cundinamarca . The remaining Muisca people in central Colombia also have their own seal. The Muisca culture had certain sports which were part of their rituals. The turmequé game, also known as tejo , has survived and became

3317-685: The Muisca Confederation before the Spanish conquest . The people spoke Muysccubun, a language of the Chibchan language family , also called Muysca and Mosca . They were encountered by conquistadors dispatched by the Spanish Empire in 1537 at the time of the conquest . Subgroupings of the Muisca were identified chiefly by their allegiances to three great rulers: the hoa , centered in Hunza , ruling

They proposed linguistic and cultural recuperation, defense of the territories nowadays occupied by others, and proposed urban and tourist plans. They support the communities of Ubaté , Tocancipá , Soacha , Ráquira , and Tenjo in their efforts to recover their organizational and human rights. The Muisca people of Suba opposed the drying up of

3531-581: The Punjab region of India , for example, groundwater levels have dropped 10 meters since 1979, and the rate of depletion is accelerating. A lowered water table may, in turn, cause other problems such as groundwater-related subsidence and saltwater intrusion . Another cause for concern is that groundwater drawdown from over-allocated aquifers has the potential to cause severe damage to both terrestrial and aquatic ecosystems – in some cases very conspicuously but in others quite imperceptibly because of

3638-569: The Quaternary glaciation left plenty of glacier debris, and glacier lakes such as Chisaca lake. During the Last Glacial Maximum , the glacier motion of the ice sheets through the Tunjuelo valley reached as far as Usme (today part of Bogotá ). The soil of this region is acidic, with high levels of sodium and potassium . This is a coarse-grained soil, with high permeability favoring

The community of Bosa made important achievements in its project of natural medicine in association with

3959-442: The hydraulic pressure of groundwater in the pore spaces of the aquifer and the aquitard supports some of the weight of the overlying sediments. When groundwater is removed from aquifers by excessive pumping, pore pressures in the aquifer drop and compression of the aquifer may occur. This compression may be partially recoverable if pressures rebound, but much of it is not. When the aquifer gets compressed, it may cause land subsidence,

4280-520: The Indigenous lands in Suba , a northern region in modern-day Bogotá, which had been recognized and protected by the crown, were taken away by the republican governments following a strategy of suppression of the native culture and ethnic presence in the country's largest urban centres. The Reservation of Cota was re-established on land bought by the community in 1916, and then recognized by the 1991 constitution;

4387-648: The Ministry of Interior Affairs in 2005 reports a total of 14,051 Muisca people in Colombia. Much of the historic knowledge about the Muisca comes from the testimonies of conquistadors and colonists Gonzalo Jiménez de Quesada ; Spanish poet , soldier , and priest Juan de Castellanos (16th century); bishop Lucas Fernández de Piedrahita and Franciscan Pedro Simón (17th century). More recently, Javier Ocampo López and Gonzalo Correal Urrego have contributed notable scholarship. Knowledge of events up until 1450

In consequence, the peasants often invade the protected area to grow potato crops. The natural forest line is severely altered by human activity (logging, intensive grazing), which makes

5136-545: The age of groundwater obtained from different parts of the Great Artesian Basin, hydrogeologists have found it increases in age across the basin. Where water recharges the aquifers along the Eastern Divide , ages are young. As groundwater flows westward across the continent, it increases in age, with the oldest groundwater occurring in the western parts. This means that in order to have travelled almost 1000 km from

5243-405: The aquifer reduces the water pressure in the confining layer, causing it to compress from the weight of overlying geologic materials. In severe cases, this compression can be observed on the ground surface as subsidence . Unfortunately, much of the subsidence from groundwater extraction is permanent (elastic rebound is small). Thus, the subsidence is not only permanent, but the compressed aquifer has

5350-525: The aquifers are likely to run dry in 60 to 100 years. Groundwater provides critical freshwater supply, particularly in dry regions where surface water availability is limited. Globally, more than one-third of the water used originates from underground. In the mid-latitude arid and semi-arid regions lacking sufficient surface water supply from rivers and reservoirs, groundwater is critical for sustaining global ecology and meeting societal needs of drinking water and food production. The demand for groundwater

The Muisca used little furniture as they would typically sit on the floor. Rivalries between the zaque and the zipa were taken advantage of by the Spaniards as they conquered the heart of what would be Colombia. Some of them, such as Sebastián de Belalcázar , Gonzalo Jiménez de Quesada , and Nicolás de Federman , interested in locating El Dorado , discovered

5778-401: The arrival of the Spanish invaders. They left abundant traces of their occupation that have been studied since the 16th century, and allow scientists to reconstruct their way of life. It is possible that the Muisca integrated with more ancient inhabitants, but the Muisca were the ones who molded the cultural profile and the social and political organization. Their language, a dialect of Chibcha ,

5885-598: The atmosphere and fresh surface water (which have residence times from minutes to years). Deep groundwater (which is quite distant from the surface recharge) can take a very long time to complete its natural cycle. The Great Artesian Basin in central and eastern Australia is one of the largest confined aquifer systems in the world, extending for almost 2 million km . By analysing the trace elements in water sourced from deep underground, hydrogeologists have been able to determine that water extracted from these aquifers can be more than 1 million years old. By comparing

In irrigation districts, poor drainage of soils and surface aquifers can result in water tables' coming to the surface in low-lying areas. Major land degradation problems of soil salinity and waterlogging result, combined with increasing levels of salt in surface waters. As a consequence, major damage has occurred to local economies and environments. Aquifers in surface irrigated areas in semi-arid zones with reuse of

By comparison, weathered and fractured crystalline rocks yield smaller quantities of groundwater in many environments. Unconsolidated to poorly cemented alluvial materials that have accumulated as valley -filling sediments in major river valleys and geologically subsiding structural basins are included among

7169-404: The globe includes canals redirecting surface water, groundwater pumping, and diverting water from dams. Aquifers are critically important in agriculture. Deep aquifers in arid areas have long been water sources for irrigation. A majority of extracted groundwater, 70%, is used for agricultural purposes. In India, 65% of the irrigation is from groundwater and about 90% of extracted groundwater

Underground reservoirs contain far more water than the capacity of all surface reservoirs and lakes in the US, including the Great Lakes . Many municipal water supplies are derived solely from groundwater. Over 2 billion people rely on it as their primary water source worldwide. Human use of groundwater causes environmental problems. For example, polluted groundwater

This can be a serious problem, especially in coastal areas and other areas where aquifer pumping is excessive. Subsidence occurs when too much water is pumped out from underground, deflating the space below the above-surface, and thus causing the ground to collapse. The result can look like craters on plots of land. This occurs because, in its natural equilibrium state,

Espeletia cuatrecasasii Ruíz-Terán & López-Fig. Espeletia formosa S.Díaz & Rodr.-Cabeza Espeletia glossophylla Mattf. Espeletia killipii Cuatrec. Espeletia picnophyla Cuatrec. Espeletia schultzii (Benth.) W.M.Curtis and Espeletia curialensis Cuatrec. The Sphagnum moss covers wide areas of Sumapaz, which increases

8239-647: The most powerful of the American Post-Classic stage , mainly because of the precious resources of the area: gold and emeralds. When the Spaniards arrived in Muisca territory they found a rich state, with the Muisca Confederation controlling mining of the following products: The Muisca traded their goods at local and regional markets with a system of barter . Items traded ranged from those of basic necessity through to luxury goods. The abundance of salt, emeralds, and coal brought these commodities to de facto currency status. Having developed an agrarian society,

8346-412: The most productive sources of groundwater. Fluid flows can be altered in different lithological settings by brittle deformation of rocks in fault zones ; the mechanisms by which this occurs are the subject of fault zone hydrogeology . Reliance on groundwater will only increase, mainly due to growing water demand by all sectors combined with increasing variation in rainfall patterns . Groundwater

8453-853: The north of Boyacá to the Sumapaz Páramo and from the summits to the western portion of the Eastern Ranges . Their territory bordered the lands of the Panche in the west, the Muzo in the northwest, the Guane in the north, the Lache in the northeast, the Achagua in the east, and the Sutagao in the south. At the time of the Spaniard invasion, the area had a large population, although

8560-671: The open deserts and similar arid environments – exist on irregular rainfall and the moisture it delivers to the soil, supplemented by moisture in the air. While there are other terrestrial ecosystems in more hospitable environments where groundwater plays no central role, groundwater is in fact fundamental to many of the world's major ecosystems. Water flows between groundwaters and surface waters. Most rivers, lakes, and wetlands are fed by, and (at other places or times) feed groundwater, to varying degrees. Groundwater feeds soil moisture through percolation, and many terrestrial vegetation communities depend directly on either groundwater or

8667-470: The other two thirds. Groundwater provides drinking water to at least 50% of the global population. About 2.5 billion people depend solely on groundwater resources to satisfy their basic daily water needs. A similar estimate was published in 2021 which stated that "groundwater is estimated to supply between a quarter and a third of the world's annual freshwater withdrawals to meet agricultural, industrial and domestic demands." Global freshwater withdrawal

8774-516: The people used terrace farming and irrigation in the highlands. Main products were fruits , coca , quinoa , yuca and potatoes . Another major economic activity was weaving. The people made a wide variety of complex textiles. The scholar Paul Bahn said: "the Andean cultures mastered almost every method of textile weaving or decoration now known, and their products were often finer than those of today." The Muisca were an agrarian and ceramic society of

8881-623: The people were members of the El Abra Culture. Scholars agree that the group identified as Muisca migrated to the Altiplano Cundiboyacense in the Formative era (between 1000 BCE and 500 CE), as shown by evidence found at Aguazuque and Soacha . Like the other formative-era cultures of America, the Muiscas were transitioning between being hunter-gatherers and becoming sedentary farmers. Around 1500 BCE, groups of agrarians with ceramic traditions came to

8988-683: The percolated soil moisture above the aquifer for at least part of each year. Hyporheic zones (the mixing zone of streamwater and groundwater) and riparian zones are examples of ecotones largely or totally dependent on groundwater. A 2021 study found that of ~39 million investigated groundwater wells 6-20% are at high risk of running dry if local groundwater levels decline by a few meters, or – as with many areas and possibly more than half of major aquifers  – continue to decline. Fresh-water aquifers, especially those with limited recharge by snow or rain, also known as meteoric water , can be over-exploited and depending on

9095-466: The practice may have been extinct by the time of the Spanish conquest, as there are no first-hand Spanish accounts. Oral tradition suggests that every family gave up a child for sacrifice , that the children were regarded as sacred and cared for until the age of 15, when their lives were then offered to the Sun-god, Sué . The cult of the Muisca centered on two main deities; Sué for the Sun and Chía for

9202-524: The precise number of inhabitants is not known. Estimates vary from 1 million to over 3 million inhabitants. Their economy was based on agriculture , salt mining, trading , metalworking , and manufacturing . Due to Spanish colonization, the population of the Muisca has drastically decreased and assimilated into the general population. The descendants of the Muisca are often found in rural municipalities including Cota , Chía , Tenjo , Suba , Engativá , Tocancipá , Gachancipá , and Ubaté . A census by

9309-467: The recognition was withdrawn in 1998 by the state and restored in 2006. In 1948 the state forbade the production of chicha , a corn-based alcoholic drink. This was a blow to the culture and economy of the Muisca. The ban remained until 1991. Since then, the "Festival of the chicha, maize, life, and joy" is celebrated every year in Barrio La Perseverancia, a neighborhood in Bogotá where most of

9416-433: The region from the lowlands. They had permanent housing and stationary camps, and worked the salty water to extract salt. In Zipacón there is evidence of agriculture and ceramics. The oldest settlement of the highlands dates to 1270 BCE. Between 800 BCE and 500 BCE, a second wave of migrants came to the highlands. Their presence is identified by multicolor ceramics, housing, and farms. These groups were still in residence upon

9523-494: The rich plains of Cundinamarca and Boyacá . The presence of the Spaniards gave hope to both sovereigns that, were they to make one Confederation, they could prevail in a war against the Spaniards. But the Spaniards prevailed. The reaction of the chief leaders and the people did little to change the destiny of the Confederations. The Spanish executed the last Muisca sovereigns, Sagipa and Aquiminzaque , in 1539 and 1540 respectively. In 1542 Gonzalo Suárez Rendón finally put down

9630-423: The same terms as surface water : inputs, outputs and storage. The natural input to groundwater is seepage from surface water. The natural outputs from groundwater are springs and seepage to the oceans. Due to its slow rate of turnover, groundwater storage is generally much larger (in volume) compared to inputs than it is for surface water. This difference makes it easy for humans to use groundwater unsustainably for

9737-545: The seat of the colonial administration for the New Kingdom of Granada (Spanish: Nuevo Reino de Granada ). The origin of the legend of El Dorado (Spanish for "The Golden One") in the early 16th century may be located in the Muisca Confederation . The zipa offered gold and other treasures to the Guatavita goddess. To do so, the zipa covered himself with gold dust and washed it off in the lake while tossing gold trinkets into

9844-416: The soil's capacity to hold water and nutrients by increasing capillary forces and cation exchange capacity. In the canyons areas, encenillo tree and tibouchina are the dominant species. The European plant Digitalis purpurea is an introduced species , the way of its introduction is not known, either deliberate or accidental. The endangered spectacled bear lives in Sumapaz, its main source of food being

9951-416: The source of recharge in 1 million years, the groundwater flowing through the Great Artesian Basin travels at an average rate of about 1 metre per year. 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

10058-497: The subsurface. The high specific heat capacity of water and the insulating effect of soil and rock can mitigate the effects of climate and maintain groundwater at a relatively steady temperature . In some places where groundwater temperatures are maintained by this effect at about 10 °C (50 °F), groundwater can be used for controlling the temperature inside structures at the surface. For example, during hot weather relatively cool groundwater can be pumped through radiators in

10165-416: The territories there were four chiefdoms: Bacatá , Hunza , Duitama , and Sogamoso . The chiefdom was composed by localities. The tribes were divided into Capitanías (ruled by a capitan). There were two kinds: Great Capitania ( sybyn ) and Minor Capitania ( uta ). The status of Capitan was inherited by maternal lineage. The Muisca legislation was consuetudinary , that is to say, their rule of law

10272-433: The tribes were part of the Muisca ethnic group, sharing the same language and culture and forming relations through trade. They united in the face of a common enemy. The army was the responsibility of the zipa or zaque . The army was made up of the güeches , the traditional ancient warriors of the Muisca. The Muisca Confederation existed as the union of two lesser confederations. The southern confederation, headed by

10379-408: The unavoidable irrigation water losses percolating down into the underground by supplemental irrigation from wells run the risk of salination . Surface irrigation water normally contains salts in the order of 0.5 g/L or more and the annual irrigation requirement is in the order of 10,000 m /ha or more so the annual import of salt is in the order of 5,000 kg/ha or more. Under

10486-518: The waters. This tradition was well known outside the Confederation, as far as the Caribbean Sea ; the Spaniards were attracted by stories of a "city of gold" that did not exist. Indigenous people sometimes got rid of the avaricious Spaniards in that way, pointing them in the direction of other peoples. Lake Guatavita was explored by conquistadors who were looking for gold offerings from the zipa to

10593-441: The world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table . Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps , and can form oases or wetlands . Groundwater

10700-519: The world's liquid fresh water is groundwater. Global groundwater storage is roughly equal to the total amount of freshwater stored in the snow and ice pack, including the north and south poles. This makes it an important resource that can act as a natural storage that can buffer against shortages of surface water , as in during times of drought . The volume of groundwater in an aquifer can be estimated by measuring water levels in local wells and by examining geologic records from well-drilling to determine

10807-420: The world's total groundwater withdrawal. Groundwater may or may not be a safe water source. In fact, there is considerable uncertainty with groundwater in different hydrogeologic contexts: the widespread presence of contaminants such as arsenic , fluoride and salinity can reduce the suitability of groundwater as a drinking water source. Arsenic and fluoride have been considered as priority contaminants at

10914-455: Was cut short by the Spanish conquest. This search for an identity resulted in giving emphasis to the Muisca culture and overlooking other native nations, which were seen as wild people. Researchers wrongly concluded that the Muisca culture inhabited a previously empty land and that all archeological finds could be attributed solely to the Muisca. In 1849 president Tomás Cipriano de Mosquera invited Italian cartographer Agustín Codazzi , who led

11021-409: Was determined by long-extant customs with the approval of the zipa or zaque . This kind of legislation was suitable to a confederation system, and it was a well-organized one. The natural resources could not be privatized: woods, lakes, plateaus, rivers and other natural resources were common goods. Chibcha , also known as muysca , mosca , or muysca cubun , belongs to the Chibchan languages . It

11128-462: Was named by the Spaniards "País de la Niebla" ("Country of Fog") because of the dense clouds at ground level, with great decrease in visibility. In 1783, José Celestino Mutis led the Botanic Expedition, with the purpose of studying the flora and fauna of the region. However, the páramo was not visited because of its harsh climatic conditions. The German naturalist Alexander von Humboldt made

11235-402: Was probably around 600 km per year in 1900 and increased to 3,880 km per year in 2017. The rate of increase was especially high (around 3% per year) during the period 1950–1980, partly due to a higher population growth rate, and partly to rapidly increasing groundwater development, particularly for irrigation. The rate of increase is (as per 2022) approximately 1% per year, in tune with

11342-401: Was spoken across several regions of Central America and the north of South America . The Tairona culture and the U'wa , related to the Muisca culture, speak similar languages, which encouraged trade. The Muisca used a form of hieroglyphs for numbers. Many Chibcha words were absorbed or "loaned" into Colombian Spanish: The Muisca had an economy and society considered to have been one of

11449-462: Was very similar to those peoples of the Sierra Nevada de Santa Marta ( Kogui , Ijka, Wiwa , and Kankuamo ) and the Sierra Nevada del Cocuy ( U'wa ). Zipa Saguamanchica (ruled 1470 to 1490) was in a constant war against aggressive tribes such as the Sutagao , and especially the Panche , who would also make difficulties for his successors, Nemequene and Tisquesusa . The Caribs were also
