In cities where space is at a premium, many rivers are covered and built over. But around the world there's a growing trend among cities to "daylight" or uncover portions of their rivers.

"More recently in the US, $19m was invested to daylight the Saw Mill River in downtown Yonkers, New York. The aim was to regenerate the area and bring back habitat for a range of species including muskrats and snapping turtles," David Cox writes in the Guardian.
