MACARÉ is a film research by Sana na N’Hada. The Tabanca Enxalé, a Balanta village, is located on a peninsula where the Geba River meets the Corubal River. The village is surrounded by rice fields and mangrove forests on which the natural phenomenon of the tidal wave Macaré occurs. There is evidence in the theory of continental drift that suggests that the Geba Canal in Guinea-Bissau was a junction of the Amazon River in Brazil when the two continents were connected in a different geological time. Macaré is a natural phenomenon that only takes place in a few places in the world (e.g. in the Amazon and the Geba River) and shows the collision of the river water with the ocean waves at the onset of the tide. It is best perceived at the new moon at the autumn equinox, i.e. at the end of the rainfalls in September (this year it was on September 18, 2020). Since the construction of a dam on the Geba River in Senegal, this phenomenon has changed enormously in Enxalé. The research aims to deepen the understanding of life in alluvial land and the traditional uses and cosmology of the mangrove ecosystem.
