Andean agriculture
From Wikipedia, the free encyclopedia
Current agricultural practices of the Andean region of South America typically involve a synthesis of traditional Incan practices and modern techniques to deal with the unique terrain and climatic elements of the area. Millions of farmers in economically impoverished communities make a living producing staple crops such as potato, olluco, and mashua for their own consumption as well as profit in local and urban markets.[1] The Andean region is particularly known for its wide variety of potato species, boasting over about 5,000 varieties identified by the International Potato Center based in Peru.[2] These crops are arranged within the mountains and plateaus of the Andes in four distinct landscape-based units described as Hill, Ox Area, Early Planting, and Valley which overlap one another in a patchwork-styles of plateau surfaces, steep slopes, and wetland patches.[3] Within each of these units, farmers classify soil types as either puna (deep soils) or suni (thin, slope soils) (local names may vary per region).[3]

Andean farmers must contend with the severe fluctuations in temperature, the unpredictability of the rainy season, and a multitude of pest threats on the daily.[4] To cope with such challenges, many farmers try protect their crops by cultivating a diverse array of species rather than a monoculture. Communities engage in many cultural and faith-based practices to ensure a good harvest and season. They highly value ancestral wisdom and call on it often for agricultural and social endeavors. Many farmers still use Incan-style terraces and irrigation systems for cultivation.[4]
