Atacama Region

geography Maturity 11-13 Next article →

The Atacama Region is a major administrative division in Chile. It is one of the country's 16 first-order divisions. This region is located in the southern part of the Atacama Desert. To the west, the region meets the Pacific Ocean. To the north, it borders the Antofagasta Region. To the south, it borders the Coquimbo Region. To the east, it shares borders with Argentina. Specifically, it touches the Argentine provinces of Catamarca, La Rioja, and San Juan. The region is organized into three provinces: Chañaral, Copiapó, and Huasco.

The landscape of the Atacama Region changes based on its geography. North of the Copiapó River, the land is a true desert. South of this river, the environment is mostly semi-arid. This means it is dry but receives slightly more moisture. In the northern inland areas, the terrain is also different. This area hosts active volcanoes. These volcanoes are part of the Central Volcanic Zone of the Andes. This geological feature adds a layer of volcanic activity to the desert landscape.

Geology plays a massive role in the economy of this region. There are four distinct metallogenetic belts in the area. These belts are zones where valuable metal deposits are found. From west to east, the first is the Atacama Fault System. This system contains copper and iron. The second is the Inca de Oro Belt, which holds silver and gold. The third is the West Fissure System, which contains copper. Finally, the Maricunga Belt sits near the Argentine border and holds gold.

Mining is the most important industry for the Atacama Region. It accounts for 41% of the regional Gross Domestic Product, or GDP. Mining also makes up 90% of the region's total exports. The region is known for having many small and medium-scale mines. This is different from northern regions like Tarapacá, where large-scale mining dominates. Many small mines sell their products to ENAMI. This is the national mining company. They process the materials at a smelter located in Paipote. The Candelaria mine is the largest copper deposit here. It produces about 200,000 tonnes of copper every year. The El Salvador mine is the second largest. It is owned by CODELCO and produces about 81,000 tonnes annually.

The history of the region is tied to its natural resources. The original inhabitants were the Diaguita and Changos peoples. A major historical event occurred in 1832. This was when Juan Godoy discovered the Chañarcillo silver mine. This discovery led to a silver rush that lasted until 1850. Later, the region saw a period of heavy iron mining. This took place between 1952 and 1966. Today, the region continues to find new minerals like lithium. This makes the area a vital part of Chile's economic history.

While much of the land is desert, people have found ways to farm. Agriculture is mostly found in the Copiapó and Huasco valleys. Farmers use irrigation to help their crops grow. They rely on the Lautaro dam in the Copiapó valley. They also use the Santa Juana dam in the Huasco valley.

The sunny climate provides a major advantage. Fruit ripens earlier here than in other parts of Chile. This allows the region to reach northern hemisphere markets first. Major crops include table grapes and pisco grapes. They also grow olives, alfalfa, tomatoes, and various flowers.

Human activity also impacts the local wildlife. The region is home to the lesser rhea. This is a large, terrestrial bird known scientifically as Rhea pennata tarapacensis. This specific subspecies is currently considered endangered. The population has decreased due to hunting in the past. However, the main cause of their decline is agricultural land conversion. As the human population grows, more land is used for farming. This leaves less space for the birds to live.

Beyond mining and farming, the region uses its environment for new technologies. The Atacama Desert has very rare cloudy days. This unique weather is perfect for solar power generation. Because of this, many PV and CSP plants are being built. PV stands for photovoltaic, which turns sunlight into electricity. CSP stands for concentrated solar power. Additionally, the ocean supports aquaculture. This is the farming of aquatic organisms. The region produces scallops, oysters, mussels, and various types of algae. These industries help the region connect its natural resources to the modern world.
