Yaku Raymi: The Quechua Ritual to Save a Glacier


In Santa Fe, Peru, an ancestral system of water storage is helping communities cope with water scarcity: qochas are artificial lagoons built to store rainwater during the wet season, which is later used during droughts. The use of qochas has allowed Santa Fe to have 41 reservoirs that store 2.9 million cubic meters (102.4 million cubic feet) of water, three times more than before.
