ISLA ASIA, CAÑETE, PERU - DECEMBER 2017: Guano workers during a work day in Isla Asia.
The boom of organic farming has brought Guano back to its splendor. Considered the best organic fertilizer in the world, guano made up of the droppings of guano birds - pelicans, pikemen, cormorants, guanayes, penguins, tendrils - has been a treasure of Peru since the time of the Inca culture. His method of extraction has not changed since then and every year thousands of people from the poorest regions of Peru come to the call of guano to work tirelessly for eight months in semi-slave regime in the harvesting campaign of Guano.
