Chaco Province

Chaco derives from chacú, the Quechua word used to name a hunting territory or the hunting technique used by the people of the Inca Empire.

Annually, large groups of up to thirty thousand hunters would enter the territory, forming columns and circling their prey.[5] Jesuit missioner Pedro Lozano wrote in his book Chorographic Description of the Great Chaco Gualamba, published in Cordoba, Spain in 1733: "Its etymology indicates the multitude of nations that inhabit that region. When they go hunting, the Indians gather from many parts the vicuñas and guanacos; that crowd is called chacu in the Quechua language, which is common in Peru, and that Spaniards have corrupted into Chaco".[6]

However, the earliest known mention of the term in a document was in a letter written to Fernando Torres de Portugal y Mesía, Viceroy of Peru, dated in 1589, by the then Governor of Tucumán, Juan Ramírez de Velasco, who referred to the region as Chaco Gualamba.[7] (The term Gualamba is of uncertain origin and has since fallen into disuse.[7])

The province of Chaco lies within the southern part of the Gran Chaco region, a vast lowland plain that covers territories in Argentina, Paraguay, and Bolivia.

Chaco Province covers an area of 99,633 km² (38,469 sq mi) and ranks as the twelfth largest Argentinian province. The highest ground in the province is also the most western, near the municipality of Taco Pozo, at an elevation of 272 m (892 ft) above sea level.[8]

The Paraná and Paraguay rivers separate Chaco province from Corrientes Province and the Republic of Paraguay. To the north, the river Bermejo forms another natural border, dividing Chaco Province from Formosa Province.

In the south, the border follows the 28th parallel south, separating the region from Santa Fe Province, while in the west it borders Salta and Santiago del Estero.

Other important rivers include: the Negro, Tapenagá, Palometa, and Salado, all tributaries or anabranches of the river Paraná.

The province has a subtropical climate.[9] It is divided in two different climate zones: a more humid one in the east and a drier subtropical climate in the center and west.[10] The eastern parts of the province have a humid subtropical climate (Cfa under the Köppen climate classification) with no dry season.[11] In the west where precipitation is lower, it has a subtropical climate with a dry winter and is classified as a semi-arid climate (BS under the Köppen climate classification) due to potential evapotranspiration exceeding precipitation.[11]

The area was originally inhabited by various hunter-gatherers speaking languages from the Mataco-Guaicru family. Native tribes including the Toba, and Wichí survive in the region and have important communities in this province as well as in Formosa Province.

In 1576, the governor of a province in Northern Argentina commissioned the military to search for a huge mass of iron, which he had heard that natives used for their weapons. The natives called the area Heavenly Fields, which was translated into Spanish as Campo del Cielo. This area is now a protected region situated on the border between the provinces of Chaco and Santiago del Estero where a group of iron meteorites fell in a Holocene impact event some four to five thousand years ago. In 2015, Police arrested four alleged smugglers trying to steal over a ton of legally protected meteoric iron.[12]

The first European settlement was founded by Spanish conquistador Alonso de Vera y Aragón, in 1585, and was called Concepción de Nuestra Señora. It was abandoned in 1632. During its existence, it was one of the most important cities in the region, but attacks from local Indians forced the residents to leave. In the 17th century, the San Fernando del Río Negro Jesuit mission was founded in the area of the modern-day city of Resistencia, but it was abandoned fifteen years later.

The Gran Chaco region remained largely unexplored, and uninhabited, by either Europeans or Argentines until the late 19th century, after numerous confrontations between Argentina and Paraguay during the War of the Triple Alliance. San Fernando was re-established as a military outpost, and was renamed Resistencia in 1876.

The Territorio Nacional del Gran Chaco was established in 1872. This territory, which included the current Formosa Province and lands presently inside Paraguay, was superseded by Territorio Nacional del Chaco upon its administrative division, in 1884.

Between the end of the nineteenth and the first decades of the twentieth centuries, the province received a variety of immigrants, among them Volga Germans and Mennonites from Russia, Germany, and Canada. They, alongside other immigrants, transformed Chaco into a productive farming region known for its dairy and beef production.

Chaco's economy, like most in the region, is relatively underdeveloped, yet has recovered vigorously since 2002. It was estimated to be US$4.397 billion in 2006, or US$4,467 per capita (half the national average and the third-lowest in Argentina).[17] Chaco's economy is diversified, but its agricultural sector has suffered from recurrent droughts over the past decade.

Agricultural development in Chaco is predominantly associated with the commercial growing of quebracho wood and cotton. Chaco currently produces 60% of Argentina's national cotton production. Agricultural food production accounts for 17% of Argentina's output. This includes crops such as soy, sorghum, and maize. Sugarcane is also cultivated in the south, as well as rice and tobacco to a lesser degree.

Cattle breeds consisting of crosses with zebu are regarded as better adapted to the high temperatures, grass shortage and occasional flooding than intensively reared pure-breeds.

Industrial contributes approximately 10% to the provincial economy and includes textiles produced from local cotton, oil and coal production, and sugar, alcohol and paper, all derived from sugar cane.

Chaco is home to the Chaco National Park, but tourism is not a well-developed industry in the province. The province's main airport, Resistencia International Airport, serves around 100,000 passengers annually.

The provincial government is divided into the usual three branches: the executive, headed by a popularly elected governor, who appoint the cabinet; the legislative; and the judiciary, headed by the Supreme Court and completed by several inferior tribunals.

The Constitution of Chaco Province forms the formal law of the province.

In Argentina, the most important law enforcement organization is the Argentine Federal Police but the additional work is carried out by the Chaco Provincial Police.

The province is divided into 25 departments (Spanish: departamentos).
