Résumé :
|
Many rivers, lakes and other inland waters have been modified and degrated by human activities. Rehabilitation of degrated systems and mitigation of impacts of ongoing stresses are needed to preserve ecosystem services and fisheries and are of a high priority if the aquatic biodiversity of inland waters is to be conserved. A number of technical solutions for rehabilitation and mitigation are available to restore habitat diversity, provide for environmental flows and ensure longitudinal and lateral connectivity within such systems. After execution, rehabilitation projects should be carefully monitored in order to meet the objectives.
