Ana Anza, 65, farms garlic in Caspana, an oasis in Atacama Desert, northern Chile, January 2009. Caspana is one of the very few places in the desert where villagers - descendants of the Atacameños indigenous group - protected their rights to clean unpolluted waters of Caspana river (a tributary of Loa river) for their agriculture against the cities and mining companies on their quest for water.
