Memória sobre a plantação dos algodões e sua exportação sobre a decadencia da lavoura de mandiocas, no termo da villa de Camamú, Comarca dos Ilhéos, Governo da Bahia

A vivid memoir from the late eighteenth century, this work records the observations of a Coimbra‑trained naturalist who was tasked with surveying the cotton plantations of Camamú, in the island district of Bahia. He details the booming export trade that made cotton one of the colony’s most valuable crops, while also chronicling the gradual decay of the once‑thriving cassava fields that sustained local families. The narrative captures the hopes of colonial officials who saw cotton as a pathway to wealth and national pride.

Interwoven with these economic notes are the author’s scientific reflections on climate, soil, and the limits of human intervention. He explains why European vines and olives struggle to thrive on Brazilian coasts, emphasizing that temperature and rainfall shape a plant’s destiny more than any farmer’s adjustments. The text reads like a thoughtful dialogue between a curious scholar and the tropical landscape he strives to understand.
