Bolivia's Mountainous Landscape: A Natural Wonder

Bolivia is a landlocked country in west-central South America, with a diverse geography that includes rugged mountains, dense rainforests, massive salt flats, and a rich cultural heritage. The country is bordered by Brazil, Paraguay, Argentina, Chile, and Peru, with its geography largely split into the Andean Altiplano and the Eastern lowlands. The Andean mountain range, one of the world's longest, runs along the country's western border, with the Bolivian Andes dominating the western third of the country. The Andean Region, covering the western 28% of Bolivia, is highly mountainous and includes parts of La Paz, Potosí, Oruro, Chuquisaca, and Cochabamba. The Altiplano, a high plateau between the Andean ranges, is one of the world's highest inhabited regions, with altitudes ranging from 12,000 to 14,000 feet. Bolivia's highest peak, the snow-capped Sajama, rises to 6,542 meters in the Cordillera Occidental, a chain of dormant volcanoes in the Andean Region.

The Andes Mountains

Bolivia is a landlocked country in west-central South America, with a land area of about 1,098,581 square kilometres. The country is bordered by Brazil to the north and east, Paraguay to the southeast, Argentina to the south, Chile to the southwest, and Peru to the northwest. Bolivia is traditionally regarded as a highland country, with its mountainous western region constituting an important economic and political centre.

The Cordillera Occidental is a chain of dormant volcanoes and volcanic vents emitting sulfurous gases. Bolivia's highest peak, the snow-capped Sajama (6,542 meters), is located here. The Cordillera Oriental, on the other hand, is characterised by impressive snow-capped peaks, with some exceeding 6,000 meters in height. Between these two ranges lies the Altiplano, a lofty plateau that extends from southern Peru through Bolivia to northern Argentina. The Altiplano is a relatively flat depression about 800 kilometres wide and lying at elevations between 3,650 and 3,800 meters.

The primary mountain range within Bolivia is the Andes Mountains, which runs along the country's western border. The Andes formed mostly as a result of the subduction of the Nazca Plate under the South American Plate, leading to mountain-building along the western edge of the continent. The range is home to several volcanoes, including Nevado Sajama, Volcán Parinacota, and Volcán Pomerape.

The Altiplano

Bolivia is a landlocked country in west-central South America, straddling the Andes. The Altiplano, which means 'high plain', is a high plateau or tableland that makes up one of the country's three geographic zones. The Altiplano is the most extensive high plateau on Earth outside of Tibet. It is located at the latitude of the widest part of the north-south-trending Andes and is around 500 miles (805 kilometres) long and 80 miles (130 kilometres) wide. The bulk of the Altiplano lies in Bolivia, but its northern parts are in Peru, and its southwestern fringes are in Chile.

The Yungas

Bolivia is a landlocked country in west-central South America, with a land area of 1,098,581 square kilometres. The country is largely mountainous, with the Andes Mountains running along its western border. The mountains define Bolivia's three geographic zones: the mountains and Altiplano in the west, the semitropical Yungas and temperate valleys of the eastern mountain slopes, and the tropical lowlands or plains (llanos) of the eastern lowlands, or Oriente.

The Oriente

Bolivia is divided into three geographic zones: the mountains and Altiplano in the west, the semitropical valleys of the eastern mountain slopes (Yungas), and the tropical lowlands (llanos) of the Amazon River Basin. The Oriente, also known as the Llanos Orientales, is the largest and most sparsely populated of these regions, with the exception of Santa Cruz, eastern Bolivia's only major city.

Officially known as Santa Cruz de la Sierra, the city of Santa Cruz lies close to the Andean foothills but is very much a city of the plains. Since the mid-1950s, it has been the fastest-growing centre of agricultural colonisation in Bolivia, the main production centre for oil and natural gas, and the focus of an increasing share of electric power generation. By the 1970s, Santa Cruz had become Bolivia's second-largest city, surpassing La Paz in population by the end of the 20th century. The city boasts golf courses, fashionable neighbourhoods, and some of the country's best restaurants, and has become a popular vacation spot.

Outside of Santa Cruz, the Oriente features some of the world's most biodiverse nature reserves. The ecosystems of multi-altitude Amboró and Noel Kempff Mercado National Parks are among the most biodiverse on the planet. The rugged hills are home to unspoiled, red-roofed Spanish colonial-style villages, and the Ruta del Che (Che Guevara Trail) takes visitors through wild mountain ranges and canyons to places associated with the last days of the revolutionary's campaign.

The Llanos

Bolivia is a landlocked country in west-central South America, with a land area of about 424,000 square miles (1,099,005 square kilometres). The country is bordered by Brazil to the north and east, Paraguay to the southeast, Argentina to the south, Chile to the southwest, and Peru to the northwest. Bolivia is highly mountainous, with the Andes Mountains running along its western border. The country can be divided into three geographic zones: the mountains and Altiplano in the west, the semitropical valleys of the eastern mountain slopes (Yungas), and the tropical lowlands (llanos) of the Amazon River Basin in the east.

The plant communities in the Llanos include open grasslands, savannas with scattered trees or clumps of trees, and small areas of forest, particularly along rivers and streams. The grasslands and savannas can be further divided into seasonally flooded lowlands (llano bajo) and grasslands and savannas that remain dry throughout the year (llano alto). The llano alto grasslands and savannas are characterised by grasses and shrubs forming tussocks, with sandy and nutrient-poor soils. In contrast, the llano bajo areas have richer soils and a higher production of grasses due to the seasonal flooding.

In addition to its natural significance, the Llanos region is also economically important for cattle raising and agriculture. The flat, expansive plains are ideal for grazing, and the introduction of non-native grasses has further enhanced their suitability for livestock. Additionally, extensive areas of the Llanos are now dedicated to rice and maize farming, particularly in former seasonal wetlands. The discovery of oil and gas deposits in the region has also contributed to its economic importance.
