Description:
This graphic shows the number of new dams that were under construction in 1998. It also indicates the areas which are most affected by river channel fragmentation and flow regulation. River fragmentation is defined as the interruption of a river's natural flow by dams, inter-basin transfers or water withdrawal, and is an indicator of the degree to which rivers have been modified by human activity.
