Guano extraction in Atlantic Patagonia (1840–1880)

Abstract

Between 1840 and 1880, multiple ships travelled towards the Atlantic coast of Patagonia, engaging in guano extraction. The Patagonian guano, though of inferior quality to the Peruvian product, was one of the most valuable coastal resources of the region. Drawing on a wide variety of documents and literature, the author has explored exploitation practices and logistics. 11 guano deposits exploited have been mapped and linked with details such as vessels, companies and harbours. The history of guano in the region shows an entanglement of connections and competition regarding the resource, raising inter-imperial disputes where different state and non-state agents operated to benefit both distant and regional economies.
