This agricultural method was also revived by Alan Kolata of the University of Chicago in 1984, in Tiwanaku, Bolivia as well as Puno, Peru. Research on Waru Waru and its effectiveness in the past has led to a resurgence of the technique amongst contemporary Aymara - and Quechua -speaking native peoples in Bolivia and Peru.

Many obstacles limited Peru's agricultural production. Peru has always been rich in natural resources such as tin, silver, gold, guano and rubber. These resources ...

Agriculture was possible only with irrigation in valleys crossed by rivers coming from the high Andes, plus in a few fog oases called lomas. In the Andes, agriculture was limited by thin soils, cold ...
The vertical archipelago is a term coined by sociologist and anthropologist John Victor Murra under the influence of economist Karl Polanyi to describe the native Andean agricultural economic model of accessing and distributing resources.
Scientists explain the loss of the Humboldt Glacier in Venezuela's Sierra Nevada, which they believe makes the South American country the first in modern history to lose all its glaciers.
A water channel to drain and irrigate andenes. Andenes were complicated to build, requiring provisions for drainage and irrigation. The first step in constructing an andén was to lay an underground or bedrock foundation about 1 metre (3.3 ft) deep to lend strength and stability to the retaining wall, which might rise about 2 metres (6.6 ft) above the slope of the ground.
