War against sand
Description
Niger is crossed from east to west by the river of the same name, which until now has ensured relative prosperity to its population. The Sahara desert, pushed by winds from the north, is advancing relentlessly. The sands have been carried as far as the banks of the river, that they are gradually stifling. In just a few decades, the average depth has decreased by half and sometimes, during periods of drought, the river stops flowing altogether. The other consequence is just as worrying: heavy rains cause faster, more widespread flooding than before--.
