Temporary waters are waterways that don’t always have a visible connection to nearby surface waters, such as rivers and lakes, during the course of a year. Nevertheless, that dry stream bed or marsh area is part of the larger water network. A study released earlier this month in the journal Science outlines the value of temporary waters and describes how numerous countries do not include such waterways in their legal frameworks. Leaving temporary waterways outside of the law also leaves them vulnerable to human activity, like development and pollution, which can damage the surrounding water network. The study’s authors point out that the numbers of temporary waterways are underestimated in various parts of the world, and that their frequency will increase due to climate change.
