| Abstract: | Droughts are natural hazards characterized by a prolonged period of below-average precipitation. Water scarcity is defined as insufficient water resources to meet demands in a region. This paper examines three regions (Spain, California, and the Murray-Darling Basin in Australia) which share similar social and climatic characteristics and face severe water-scarcity problems. The frequency and persistence of droughts in these regions over the last few decades have triggered changes in water laws as well as in the behaviour of water users and managers. This paper compares the major water reforms in these regions and the achievements and failures of the various approaches implemented. This comparison shows how, despite the differences in institutions and governance regarding water allocation in the three regions, recent droughts have catalysed the creation of institutions and the implementation of sophisticated long-term measures to mitigate the impact of future droughts. A deeper understanding of the effectiveness of mechanisms and regulations is necessary to better manage droughts since the uncertain impacts of climate change will require responses of a more effective nature. |
