The frequent occurrence of drought and the increasing severity of its impacts make the traditional emergency approach inadequate and call for a risk-management approach, particularly in order to reduce water shortages in water supply systems.

Abstract

The frequent occurrence of drought and the increasing severity of its impacts make the traditional emergency approach inadequate and call for a risk-management approach, particularly in order to reduce water shortages in water supply systems. This paper attempts to provide a review of criteria, methods and tools for the management of drought risk in water systems, beginning with a discussion of legislative and institutional frameworks for coping with drought; objectives and contents of drought-planning instruments (at strategic, tactical and emergency levels) are then discussed. The review focuses on: 1. the drought indices to be used for an effective monitoring and early warning system; 2. the methods for assessing the risk of water shortage due to drought; and 3. the measures for reducing societal vulnerability to droughts and mitigating their impacts. Better coordination of drought-preparedness planning tasks, adaptive operation of water supply systems to prevent severe shortages, and more extensive use of early drought warning are suggested. Further research needs are identified.
