This week's Proba-V image shows the interaction between sand ridges, canals and lakes in the northern part of the Inner Niger Delta, in Mali.
Just south of the Sahara Desert, the Delta forms an oasis in its semi-arid surroundings that helps sustain palm and gum trees on the ridges and African manatees in its rivers.
The Niger River, flowing in its typical curve-shape, is the source of livelihood for many Sahelians.
This portion of the river flows north between grasslands on the floodplains of the lower Inner Niger Delta, and the town of Timbuktu to the northeast.
Lake Niangay, the largest lake in this daily synthesis image, is the second largest lake in Mali, and is about to be refilled by the July-October rainy season.
