River diversion could change climate in delta ecosystems


  • Anonymous


When humans divert excessive amounts of water from their natural courses, ensuing impacts on regional and global climate may threaten the fragile ecosystems around the mouths of rivers.

David Smith, a geographer at the National Center for Atmospheric Research in Boulder, Colo., is researching this problem by concentrating on river deltas, which are recognized for their fertile soils and abundance of water. As a result, river deltas are also sites of intense agricultural production and high population density.
