The Atrato River

The Atrato River (Spanish : Río Atrato) is a river of northwestern Colombia. It rises in the slopes of the Western Cordillera and flows almost due north to the Gulf of Urabá (or Gulf of Darién), where it forms a large, swampy delta. [1] Its course crosses the department of Chocó, forming that department's border with neighbouring Antioquia on two occasions. Its total length is about 650 km (400 mi), and it is navigable as far as Quibdó (400 km / 250 mi).

Spanish language Romance language

Spanish or Castilian is a Romance language that originated in the Castile region of Spain and today has hundreds of millions of native speakers in the Americas and Spain. It is a global language and the world's second-most spoken native language, after Mandarin Chinese.

River Natural flowing watercourse

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.

Colombia Country in South America

Colombia, officially the Republic of Colombia, is a sovereign state largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and Peru. It shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, Haiti, and the Dominican Republic. Colombia is a unitary, constitutional republic comprising thirty-two departments, with the capital in Bogotá.

Flowing through a narrow valley between the Cordillera and coastal range, it has only short tributaries, the principal ones being the Truando River, the Sucio River, and the Murrí River. The gold and platinum mines of Chocó line some of its confluents, and the river sands are auriferous. [1]

The Murrí River is a river of Colombia. It drains into the Caribbean Sea via the Atrato River.

Gold Chemical element with atomic number 79

Gold is a chemical element with symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium.

Platinum Chemical element with atomic number 78

Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning "little silver".

Northwestern Colombia encompasses an area of great diversity in wildlife. During the Pleistocene era at the height of the Atrato river, where it intersected the Cauca-Magdalena, the area was covered by a sea. It is proposed that this created a geographic barrier that may have caused many species to diverge through the process of allopatric speciation. [2] For example, Philip Hershkovitz proposed that the cotton-top tamarin (Saguinus oedipus) and the white-footed tamarin (Saguinus leocopus) diverged by the Atrato, and are today principally separated by the river. [2]

The Pleistocene is the geological epoch which lasted from about 2,588,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology.

Cauca River river in Colombia

The Cauca River is a river in Colombia that lies between the Occidental and Central cordilleras. From its headwaters in southwestern Colombia near the city of Popayán, it joins the Magdalena River near Magangué in Bolívar Department, and the combined river eventually flows out into the Caribbean Sea. It has a length of 965 km (600 mi) to its junction with the Magdalena, for a total length of 1,350 km (840 mi). from origin to seamouth. The river is under the supervision of the Corporación Regional del Cauca and the Corporación Autonoma Regional del Valle del Cauca, and is navigable for 640 km (400 mi) above its junction with the Magdalena.

Magdalena River river in Colombia

The Magdalena River is the principal river of Colombia, flowing northward about 1,528 kilometres (949 mi) through the western half of the country. It takes its name from the biblical figure Mary Magdalene. It is navigable through much of its lower reaches, in spite of the shifting sand bars at the mouth of its delta, as far as Honda, at the downstream base of its rapids. It flows through the Magdalena River Valley.

In the 19th and early 20th centuries the San Juan River (Colombia) and the Atrato attracted considerable attention as a feasible route for a trans-isthmian canal, [1] but the Panama Canal was built instead.

San Juan River (Colombia) important river of Colombia

The San Juan River is an important river of Colombia that flows into the Pacific Ocean through the Chocó Department. It is approximately 380 kilometres (240 mi) and drains a watershed of 2,100 square kilometres (810 sq mi). The river drains into a large delta that covers nearly 300 square kilometres (120 sq mi).

Panama Canal Large artificial waterway in the Republic of Panama, connecting the Atlantic and Pacific Oceans

The Panama Canal is an artificial 82 km (51 mi) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. Canal locks are at each end to lift ships up to Gatun Lake, an artificial lake created to reduce the amount of excavation work required for the canal, 26 m above sea level, and then lower the ships at the other end. The original locks are 34 m wide. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded canal began commercial operation on June 26, 2016. The new locks allow transit of larger, post-Panamax ships, capable of handling more cargo.

The Colombia Constitutional Court found in November 2016 that the Atrato River basin possesses rights to "protection, conservation, maintenance, and restoration." This ruling came about as a result of degradation to the river basin from mining, impacting nature and harming of Indigenous peoples and their culture. The court referred to the New Zealand declaration of the Whanganui River as a legal person holding environmental personhood. The court ordered that joint guardianship would be undertaken in the representation of the Atrato River basin. Similarly to the New Zealand declaration, the representatives would come from the national government and the Indigenous people living in the basin. [3]

Constitutional Court of Colombia

The Constitutional Court of Colombia is the supreme constitutional court of Colombia. Part of the Judiciary, it is the final appellate court for matters involving interpretation of the Constitution with the power to determine the constitutionality of laws, acts, and statutes.

Environmental personhood is a legal concept which designates certain environmental entities the status of a legal person. This assigns to these entities, the rights, protections, privileges, responsibilities and legal liability of a legal personality. Environmental personhood emerged from the evolution of legal focus in pursuit of the protection of nature. Over time, focus has evolved from human interests in exploiting nature, to protecting nature for future human generations, to conceptions that allow for nature to be protected as intrinsically valuable. This concept can be used as a vehicle for recognising Indigenous peoples' relationships to natural entities, such as rivers. Environmental personhood, which assigns nature certain rights, concurrently provides a means to individuals or groups such as Indigenous peoples to fulfill their human rights.

Geography of Colombia

The Republic of Colombia is a transcontinental country largely situated in the northwest of South America, with territories in North America. Colombia is bordered to the northwest by Panama; to the east by Venezuela and Brazil; to the south by Ecuador and Peru; and it shares maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic, and Haiti. Colombia is the 26th largest nation in the world and the fourth-largest country in South America after Brazil, Argentina, and Peru. Despite its large territory, Colombia's population is not evenly distributed, with most Colombians living in the mountainous western portion of the country as well as the northern coastline, most living in or near the capital city of Bogotá. The southern and eastern portions of the country are mostly sparsely inhabited tropical rainforest, and inland tropical plains containing large estates or large livestock farms, oil and gas production facilities, small farming communities and indigenous tribes.

Darién Gap break in the Pan-American Highway consisting of a large swath of undeveloped swampland and forest

The Darién Gap is a break in the Pan-American Highway consisting of a large swath of undeveloped swampland and forest within Panama's Darién Province in Central America and the northern portion of Colombia's Chocó Department in South America. The gap begins in Yaviza, Panama and ends in Turbo, Colombia, and is 106 km long. Roadbuilding through this area is expensive and the environmental cost is high. Political consensus in favor of road construction has not emerged.

Tamarin genus of mammals

The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus Saguinus. They are the first offshoot in the Callitrichidae tree, and therefore are sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets.

Cotton-top tamarin species of mammal

The cotton-top tamarin is a small New World monkey weighing less than 0.5 kg (1.1 lb). This New World Monkey can live up to 24 years old, but most of them die at 13 years old. One of the smallest primates, the cotton-top tamarin is easily recognized by the long, white sagittal crest extending from its forehead to its shoulders. The species is found in tropical forest edges and secondary forests in northwestern Colombia, where it is arboreal and diurnal. Its diet includes insects and plant exudates, and it is an important seed disperser in the tropical ecosystem.

Emperor tamarin species of mammal

The emperor tamarin, is a species of tamarin allegedly named for its resemblance to the German emperor Wilhelm II. It lives in the southwest Amazon Basin, in east Peru, north Bolivia and in the west Brazilian states of Acre and Amazonas.

White-footed tamarin species of mammal

The white-footed tamarin is a tamarin species endemic to Colombia. It is a silvery brown colour with pale streaks and russet underparts, and is very similar in appearance to the cotton-top tamarin, from which it is separated by the Atrato River. It is thought that the two species diverged during the Pleistocene, at a time when a sea occupied the area between their present ranges. This tamarin is an arboreal species, living in small family groups in the canopy. Females give birth to one to three young after a gestation period of about 140 days. This species has a relatively small range and is under threat from destruction and fragmentation of the forest in which it lives and the International Union for Conservation of Nature has assessed its conservation status as "endangered".

Cordillera Occidental (Colombia) western branch of the Andes in Colombia

The Cordillera Occidental is the lowest in elevation of the three branches of the Colombian Andes. The average altitude is 2,000 m (6,600 ft) and the highest peak is Cerro Tatamá at 4,100 m (13,500 ft). The range extends from south to north dividing from the Colombian Massif in Nariño Department, passes north through Cauca, Valle del Cauca, Risaralda, Chocó, and Caldas Departments to the Paramillo Massif in Antioquia and Córdoba Departments. From this massif the range divides further to form the Serranías de Ayapel, San Jerónimo and Abibe. Only to recede into the Caribbean plain and the Sinú River valley.

Natural regions of Colombia

Because of its natural structure, Colombia can be divided into six very distinct natural regions. These consist of the Andean Region, covering the three branches of the Andes mountains found in Colombia; the Caribbean Region, covering the area adjacent to the Caribbean Sea; the Pacific Region adjacent to the Pacific Ocean; the Orinoquía Region, part of the Llanos plains mainly in the Orinoco river basin along the border with Venezuela; the Amazon Region, part of the Amazon rainforest; and finally the Insular Region, comprising islands in both the Atlantic and Pacific oceans. Colombia is located in South America.

Luis Gilberto Murillo Colombian politician

Luis Gilberto Murillo Urrutia is a Colombian politician and Mining Engineer who was the Minister of Environment and Sustainable Development from 2016 to 2018. He has also served as Governor of the predominantly Afro-Colombian Department of Chocó in Colombia. Murillo was kidnapped in 2000 and after his release he went into and moved to the United States and only returned to Colombia in 2011.

Deforestation in Colombia

Colombia loses 2,000 km2 of forest annually to deforestation, according to the United Nations in 2003. Some suggest that this figure is as high as 3,000 km² due to illegal logging in the region. Deforestation results mainly from logging for timber, small-scale agricultural ranching, mining, development of energy resources such as hydro-electricity, infrastructure, cocaine production, and farming. Around one-third of the country's original forest has been removed as a result of deforestation.

Frederick M. Kelley (1822–1905) was a Wall Street banker, who sponsored 7 expeditions to discover the purported "Sea Level Interoceanic Canal" of the Isthmus of Darien.

Caquetá moist forests

The Caquetá moist forests (NT0107) is an ecoregion of tropical moist broad leaf forest to the east of the Andes in the east of Colombia, with a small section in Brazil, in the Amazon biome. The forests are in the transition between the Guiana and Amazon regions, and have highly diverse flora and fauna. They are relatively intact, although they are mostly unprotected and are threatened with deforestation to create cattle pastures.

Magdalena-Urabá moist forests

The Magdalena-Urabá moist forests (NT0137) is an ecoregion in the north of Colombia. The terrain is largely flat or undulating, but includes mountainous areas in the south. It contains moist forests and large wetlands that are important to resident and migratory birds. The ecoregion forms a bridge between the Pacific coast ecoregions of Colombia and Central America, and the ecoregions of the Andes and Amazon. It is surrounded by the more populated parts of Colombia and is threatened by farming, ranching, logging, oil exploitation and water pollution in the main rivers.

Chocó-Darién moist forests

The Chocó-Darién moist forests (NT0115) is an ecoregion in the west of Colombia and east of Panama. The region has extremely high rainfall, and the forests hold great biodiversity. The northern and southern parts of the ecoregion have been considerably modified for ranching and farming, and there are threats from logging for paper pulp, uncontrolled gold mining, coca growing and industrialisation, but the central part of the ecoregion is relatively intact.

Northwestern Andean montane forests

The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era.

Magdalena Valley montane forests

The Magdalena Valley montane forests (NT0136) is an ecoregion in the Andes mountains of central Colombia.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
