Deltas in Arid Environments

Due to increasing water use, diversion and salinization, along with subsidence sea-level rise, deltas in arid regions are shrinking worldwide. Some of the most ecologically important include Colorado, Indus, Nile, Tigris-Euphrates. The primary stressors vary globally, but these threatened by increased storage diversion, eutrophication, wetland loss. In order make sustainable over time, some flow, including seasonal flooding, needs be re-established. Positive impacts have been seen Colorado River delta after flows were increased. addition freshwater collaboration among stakeholders active management necessary. For Nile River, cooperation different nations drainage basin is important. flow into Tigris-Euphrates has affected politics civil strife Middle East, re-allocated delta. Studies commissioned for Indus recommended re-establishment monthly maintain river channel fight saltwater intrusion. However, accelerating climate impacts, socio-political conflicts, growing populations suggest a dire future deltas.
