The day the mountain fell: Sierra Leone's mudslide
I first became aware of the environmental crisis facing Freetown while living there in the summer of 2006.
That year, the rains that usually begin towards the end of April came late. As May became June, Sierra Leone's government began to ration drinking water from the Guma Dam, the primary water source for the capital.
By July, Guma had fallen to its lowest level since records began.
