Inadequate groundwater recharge

Changes in seasonal distribution of aquifer recharge due to climate change may have a significant effect of low flows in rivers supported by baseflow from rapidly responding aquifers, while rivers supported by slowly responding aquifers may show a significant delay in response.

Groundwater resources in West Asia in general and on the Arabian Peninsula in particular are in a critical condition because the volumes withdrawn far exceed natural recharge rates, threatening water distribution systems that have been used for thousands of years.

1. Vulnerability to long-term changes in precipitation patterns
2. Overexploitation of underground water resources
3. Inadequate watershed management

1. Limited catchment facilities
2. Lack of water conservation
3. Increased surface runoff
4. Ignorance of ecoregions
5. Environmentally destructive redirection of water flows
6. Destruction of natural barriers

1. Leaching of salts through irrigation

1. Rising water table
