6.2 South America
Introduction to Andean Cultures
by Dr. Sarahh Scher
A Land of Contrasts
“The Andes” can refer to the mountain range that stretches along the west coast of South America, but is also used to refer to a broader geographic area that includes the coastal deserts to the west and into the tropical jungles to the east of those mountains. This region is seen as home to a distinct cultural area—dating from around the fourth millennium B.C.E. to the time of the Spanish conquest—and many of these cultures still persist today in various forms.
From the desert coast, the mountains rise up quickly, sometimes within 10-20 kilometers of the Pacific Ocean. Therefore, the people who lived in the Andes had to adapt to varying types of climate and ecosystems. This diverse environment gave rise to a range of architectural and artistic practices.
Deserts, Mountains, and Farms
Though much of the Andean coast is near the Equator, its waters are cold, due to currents from the Antarctic. This cold water is rich in sea life; however, during El Niño years, warm water takes over, leading to large die-offs of fish and marine mammals, and often creating catastrophic flooding on the coast.
In normal years, the coast is very dry. The rivers that run to the coast, fed by melting snow from the Andes mountains (called the Cordillera Blanca, or White Mountains, in contrast to the Cordillera Negra, or Black Mountains to the west where snow does not fall), create areas of agricultural lands interspersed with desert. Cultures eventually learned to create canals, allowing them to irrigate more land, and irrigation remains important to farming on Peru’s coast.
As the elevation climbs, different ecological zones are created, and people of the Andes used these to grow different products: maize (corn), hot peppers, potatoes, and coca all grew at different elevations. Some cultures (such as the Cupisnique and Paracas) developed on the coast, and incorporated seafood into their diet. They would trade with the cultures that lived in the highlands (such as the Recuay and the inhabitants of Chavín de Huantar) for the things they could not grow for themselves. The people in the highlands would likewise trade with the coastal peoples for dried fish and products that would not grow at their elevation, as well as exotic animals like parrots from the tropical jungles to the east.
Plants and Animals
The plants and animals of the Andes provided ancient peoples with food, medicine, clothing, heat, and many other resources for daily life. As noted above, the rapid change in elevation of the Andes meant that many different foods could be grown in a compressed area. Celery was a staple food of the highlands, and maize and manioc were important in the lower elevations.
Coca grew in the highlands but was traded all over the Andes. The leaves of this plant, when chewed, provide a stim
