This layer presents ecohydrology engineering solutions that are used in 20 demonstration sites worldwide, which apply ecohydrology as a way of dealing with environmental challenges through engineering solutions. Since 2011, UNESCO-IHP promotes the establishment of various demosites around the world to apply ecohydrology principles and solutions in watersheds at all scales, to solve both social and environmental issues. The full data are available online. For more information, visit the Ecohydrology Web Platform: http://ecohydrology-ihp.org/demosites/
