50 shades of grey: moving waters and moving sands in the Limpopo River, Mozambique

This photo shows the dry sandy river bed of the Limpopo River, just downstream a major barrage in Macarretane used to feed an irrigation system.
The surrounding floodplain is used extensively by small- and large scale farming who depends on the river waters for their irrigation.
This picture was taken at the end of January, in the middle of the rainy season, and shows the devastating effects of the prolonged drought that is affecting the Southern Africa region for almost 3 years. In normal years this part of the river would be full with water.
