The number of river dam projects is predicted to rise sharply in the future, especially in the tropics where demand for hydroelectricity and water is accelerating. What are the long-term impacts of dams on highly biodiverse tropical forests? Scientists at the Smithsonian Tropical Research Institute (STRI) and collaborating institutions turned to one of the oldest tropical dams in the world to answer this question: The Panama Canal.
