Climate Change Vulnerability Assessment of the Tuban Delta Yemen

The following table summarizes the vulnerability for water security and flooding, the two hydrological climate change impacts assessed for the three regions. Flooding risk includes flash floods from rainfall and overtopping of the wadis as well as coastal flooding. Water Security includes both drought and chronic water stress.

The study further recommended that to cope with climate change and water scarcity challenges in the Tuban Delta, the following measures are needed:

1. The Lower region needs additional water resources, which can be provided by a solar-powered desalination plant.

2. Wastewater treatment plants need rehabilitation, monitoring, and appropriate plan to reuse the treated water for irrigation or for groundwater recharge.

3. Irrigation channels should be maintained, and modern irrigation method should be applied.

4. Disaster management plan should be developed coupled with an early warning system to cope with flooding and drought.

5. Groundwater discharge should be monitored to control groundwater depletion and saltwater intrusion in the Lower Region.

6. Continuous capacity building programs are needed addressing hydrological modeling, water use efficiency, water allocation and climate change adaptation.

The above-mentioned measures can be fostered by developing an Integrated Water Resource Management (IWRM) plan/strategy for the Tuban Delta.
