Atacama Region
Template:About Template:Short description Template:More citations needed Template:Infobox settlement The Atacama Region (Template:Langx, Template:IPA) is one of Chile's 16 first order administrative divisions. It comprises three provinces: Chañaral, Copiapó and Huasco. It is bordered to the north by Antofagasta, to the south by Coquimbo, to the east by the provinces of Catamarca, La Rioja and San Juan of Argentina, and to the west by the Pacific Ocean. The regional capital Copiapó is located Template:Convert north of the country's capital of Santiago. The region occupies the southern portion of the Atacama Desert, the rest of the desert is mainly distributed among the other regions of Norte Grande. As a generalization south of Copiapó River the region is mostly semi-arid and north of it is a true desert. The inland area in the north also differs from the southern part by hosting active volcanoes part of the Central Volcanic Zone of Andes.
The region has a long tradition of mining that features a silver rush from 1832 to 1850 and a strong development of iron mining from 1952 to 1966. Besides silver and iron the region also hosts valuable reserves of gold, copper and lithium. Agriculture in the region is mainly restricted to the valleys of Copiapó and Huasco where irrigation is aided by the dams of Lautaro and Santa Juana respectively. Crops cultivated include table grapes, olives, alfalfa and pisco grapes.
Demography
The Atacama Region is the third least populated region of the country, after Aisén and Magallanes. Of its total population, over 50% are located in the cities of Copiapó and Vallenar.
The largest cities are (2017 census data) Copiapó (150,804 inhabitants), Vallenar (45,298), Caldera (15,547), Chañaral (11,073), El Salvador (6,032) Tierra Amarilla (9,857), and Diego de Almagro (7,223).<ref name=census>Template:Citation</ref>
History
The original inhabitants of this area were the Diaguitas and Changos.Template:Cn
The region experienced a boom when the Chañarcillo silver mine was discovered by Juan Godoy in 1832.<ref name=mem>Template:Cite web</ref>
Natural features
Much of the region is desert, and encompasses considerable mineral resources.<ref>Teresa Moreno and Wes Gibbons. 2007</ref> Numerous flora and fauna species are found in the Atacama Region. One subspecies of the lesser rhea, known by the scientific name Rhea pennata tarapacensis, is a notable large terrestrial bird in this region, which subspecies is considered endangered. The diminished numbers of this bird are due to prehistoric and modern hunting but more significantly due to agricultural land conversion in order to feed the expanding human population.

The geology of the region has four metallogenetic belts where deposits of valuable metals are found. From west to east these belts are the Atacama Fault System (copper and iron), the Inca de Oro Belt (silver, gold), the West Fissure System (copper) and lastly the Maricunga Belt (gold) close to the Argentine border.<ref>Template:Cite journal</ref> The Chilean Iron Belt largely follows the Atacama Fault System.<ref name=Simonetal2018>Template:Cite book</ref><ref name=Travisanyetal1995>Template:Cite journal</ref>
Economy
Template:See also Mining accounts for 41%<ref>Template:Cite report</ref> of the region's GDP and 90% of its exports.Template:Fact Moreover, various geological surveys have identified new deposits.Template:Cn In Atacama Region medium and small-scale mining has a larger share of mining properties relative to large-scale mining that is dominant in the more northern regions of Tarapacá and Antofagasta.<ref>Template:Cite book</ref> The region's mining activity is centered on copper mining, but it host most of Chile's iron and gold mines. In Atacama Region there are numerous small-scale mines, which sell their output to ENAMI (the national mining company) for processing at its Paipote smelter. The region's main copper deposit is Candelaria, which produces around 200,000 tonnes per year and is controlled by Phelps Dodge, an international corporation.Template:Update inline The next in size is El Salvador, owned by CODELCO, with an annual output of around 81,000 tonnes. Both mines export through the port of Chañaral.Template:Cn
Over recent decades, fresh fruit also emerged as regional export item, when the Copiapó and Huasco valleys joined Chile’s fruit-growing boom. They enjoy a comparative advantage because, thanks to the sunny climate, fruit ripens earlier than in the rest of the country and reaches northern hemisphere markets first. Grapes are the main crop and, on a smaller scale, olives, tomatoes, peppers, onions, broad beans, citrus fruits, nectarines, apricots, oregano, and flowers. The region's organic wealth, its clear waters and sheltered bays, together with its entrepreneurial experience, favor the development of aquaculture. Species produced include the northern scallop, Japanese and Chilean oysters, abalone, turbot, algae, and different varieties of mussels. Other products with more value added include boned fish fillets, smoked and salted fish, roe, and fishburgers.
The unique weather conditions in the Atacama Desert, with extremely rare cloudy days, are ideal for solar power generation.<ref name=guardianSolar /> Many PV and CSP plants are being built in this area.<ref name=guardianSolar>Template:Cite news</ref>
