The Cajuúna River (Portuguese: Rio Cajuúna) is a river of Marajó, which itself is an island in the Amazon Delta. It is located in the state Pará in northern Brazil.
Course
editThe Cajuúna is part of a complex system of rivers and furo river channels on the western side of Marajó that botanist Jacques Huber categorised as the Afuá-Charapucu System. It runs from the Furo Charapucu in the south to the various rivers and streams around the town Afuá in the north and is bounded on the west by the Vieira Grande Bay, which connects to the Amazon River.[1]
The main town along the river is Afuá. It is located at a river bay formed by the confluence of the Cajuúna, the Afuá River and the Marajozinho River.[2][3] Within the Afuá-Charapucu System, the Cajari connects to these rivers through a river channel called the Santana Channel (Canal de Santana).[4]
This variety of river channels gives rise to various islands around Afuá. One of the largest is called Cajuúna Island (Ilha Cajuúna).[5] The vegetation of these islands is part of a biome called the Marajó várzea.[6]
Cultural geography
editThe town Afuá was founded in 1870 when Micaela Arcanja Ferreira donated a tract of land bordered by the Afuá, Cajuúna and Marajozinho rivers to construct a chapel dedicated to Our Lady of the Immaculate Conception.[7] The town is heavily influenced by the tides of these rivers.[3] They mostly depend on the water levels in Vieira Grande Bay.[8] Since many homes are built on stilts to prepare for high waters[9] and transportation is mainly by boats, the town received the ephitet "The Venice of Marajó".[10]
In Afuá a system for water collection and supply was installed at the Cajuúna. There are several sawmills along the river that mostly process timber that is transported from Portel.[11] From the town, boat tours can be organised to explore the flora and fauna along the river.[12]
The river is contained in the 59,985-square-kilometre (23,160 sq mi) Marajó Archipelago Environmental Protection Area, a sustainable-use conservation unit established in 1989 to protect the environment of the region.[13]
