Abstract: 

Central Highland is one of the driest regions in Vietnam. Extended dry spells linked to El Nino phenomenon have raised serious concerns and often affects the local economy and livelihood of local residents. The main objective of this study is to assess causes of this worsening drought problem and to suggest possible solutions for alleviating this problem. In recent years, the exploitation of excess water sources for growing high cash crops such as coffee has caused a serious imbalance between surface water and groundwater. Average temperature will increase in the future, but the rainfall total will remain the same or with no significant increase. This prolonged drought has been blamed on the provinces’ rapidly shrinking forest coverage. Therefore, rational water resources use is necessary to avoid depletion of fresh water supply for daily life. Appropriate groundwater extraction is highly recommended to prevent groundwater supply decline. Widespread water storage facilities should be promoted to harvest rainwater during rainy seasons to satisfy non-potable water requirement during dry seasons. Great quantity of rainwater/floodwater storage may mitigate prolonged drought problems frequently occur in the Central Highland region.
