Abstract

Integrated water resources management seeks an efficient blend of all water resources (e.g., fresh surface water, groundwater, reused water, desalinated water) to meet the demands of the full range of water users (e.g., agriculture, municipalities, industry, and e-flows). Water scarcity and droughts already affect many regions of the world and are expected to increase due to climate change and economic growth. In this Special Issue, 10 peer-reviewed articles have been published that address the questions regarding the economic effects of water scarcity and droughts, management instruments, such as water pricing, water markets, technologies and user-based reallocation, and the strategies to enhance resiliency, adaptation to scarcity and droughts. There is a need to improve the operation of institutions in charge of the allocation and re-allocation of resources when temporal (drought) or structural over-allocation arises. Water scarcity, droughts and pollution have increased notably in recent decades. A drought is a temporary climatic effect or natural disaster that can occur anywhere and can be short or prolonged. Water scarcity involves a lack of supply relative to potential or current demand that generates conflict between alternative uses of water, especially regarding the requirements of societies, economic sectors, territories and ecosystems. Traditionally, users in water-scarce regions have adapted to dealing with water shortages; however, droughts can greatly increase problems since they are uncertain events and also affect water-abundant regions, with climate change increasing their frequency and severity [1]. Supply-side mechanisms have traditionally been employed to cope with drought by building infrastructure (wells, dams, channels, inter-basin transfers), and recently by including desalinised, brackish, and reclaimed wastewater into the resource mix. Berbel and Esteban [2] study the influence of drought as a catalyst for water policy reform in three developed economies with a Mediterranean climate (Spain, California and Australia), and find that solutions and institutions are trajectory-dependant and grounded in social institutions. Nevertheless, there is a convergence of the type of instruments employed to manage water scarcity and droughts. In this Special Issue, the reported case studies recount experiences from USA, China, and the European Union (southern Member States). A variety of proposals aimed at tackling droughts and scarcity have been discussed, ranging from economic tools (pricing and insurance) and the increased use of reclaimed wastewater, to reforming the institutional setting (water markets and priority rights). Most of these papers analyses economic instruments and agriculture, but other economic sectors as well as non-market values are also addressed.
