Economy of Timbuktu

is rice. African floating rice (Oryza glaberrima) has traditionally been grown in regions near the river that are inundated during the annual flood. Seed is sown at the beginning of the rainy season (June–July) so that when the flood water arrives plants are already 30–40 cm in height.

The plants grow up to 3 m in height as the water level rises. The rice is harvested by canoe in December. The procedure is very precarious and the yields are low but the method has the advantage that little capital investment is required. A successful crop depends critically on the amount and timing of the rain in the wet season and the height of the flood. To a limited extent the arrival of the flood water can be controlled by the construction of small mud dikes that become submerged as the water rises.

Although floating rice is still cultivated in the Timbuktu Cercle, most of the rice is now grown in three relatively large irrigated areas that lie to the south of the town: Daye (392 ha), Koriomé (550 ha) and Hamadja (623 ha). Water is pumped from the river using ten large Archimedes' screws which were first installed in the 1990s. The irrigated areas are run as cooperatives with approximately 2,100 families cultivating small plots.
