Every drop counts: watching water from space

In this article from Science Today, Keneilwe Hlahane of the University of Cape Town writes about how satellites are used to monitor the water quality in our dams. The water is green, a clear sign that it is polluted. Dense mats of algal blooms float on the surface of the dam, turning the water a dark…
