Since I arrived in South Luangwa six weeks ago, the water level in the river has plummeted. The rains have been less than average for the past three years. Already great swathes of sandy mudbanks have emerged midstream. The flow seems to have lost its urgency. If we don’t have early rain in November, the river could stop flowing altogether, shrinking to a chain of filthy, stinking pools, filled with hippos. And their excrement.
Here are some photographs of the same location, taken a month apart.
