Abstract:Droughts are occurring in many regions of the world with increased frequency and severity. Due to the recurrence and persistence of their impacts, the strategy of crisis intervention for mitigation has shown its limits. To deal not only with the immediate effects, but also with the long-term drought impacts, researchers have recommended new strategies, which are more proactive and comprehensive. Among other suggested strategies, contingency planning is one that has been adopted as a standard method of preparing for, and managing drought impacts. There exist different frameworks for the contingency planning of drought impacts management. Capitalizing on the proposed planning frameworks, many states in the USA and other countries have defined their contingency plans for drought impacts management. However, a review of some of the existing plans evidences the need to address such critical issues as: (1) The sustainability of the water resources system under consideration with respect to the demands, drought impacts and other climatic and environmental changes; (2) The selection of the management options most relevant to conflicting management objectives in a developing drought; (3) The definition of the timing and sequencing of the implementation of the selected management actions in order to achieve the optimal mitigation; (4) The integration of the immediate objectives of drought impacts management with the strategic objectives of water resources management. This study proposes procedures for assessing the sustainability of water resources system and for integrating the strategic, tactical and emergency objectives of drought impacts management. Two methods proposed by the Delft Hydraulic Laboratory in the Netherlands (ASCE, 1998) for sustainability assessment are modified and applied. One is the modified Weighted Statistical Indices method to be applied to three flow types of the Niger River system. For the second method, a Multicriteria Decision-Analysis (MCDA) model uses the modified Weighted Criteria Indices method for assessing the relevance and sustainability of alternative options available for drought impacts management.
