Sad remnant lake emptied of fish in 15 minutes

This looks like a simple overfishing story, a lake in Mali emptied of fish in 15 minutes. But it goes deeper. This is a remnant of a once-fertile lake that was bigger and capable of feeding people, but desertification and climate change have turned this formerly green land into a barren place. Now, the ritual fishing is just a pitiful remnant of better days.
