Climate change will bring about significant changes to the capacity of, and the demand on, water resources. The resulting changes include increasing climate variability that is expected to affect hydrologic conditions. The effects of climate variability on various meteorological variables have been extensively observed in many regions around the world. Atmospheric circulation, topography, land use and other regional features modify global changes to produce unique patterns of change at the regional scale. As the future changes to these water resources cannot be measured in the present, hydrological models are critical in the planning required to adapt our water resource management strategies to future climate conditions. Such models include catchment runoff models, reservoir management models, flood prediction models, groundwater recharge and flow models, and crop water balance models. In water-scarce regions such as Australia, urban water systems are particularly vulnerable to rapid population growth and climate change. In the presence of climate change induced uncertainty, urban water systems need to be more resilient and multi-sourced. Decreasing volumetric rainfall trends have an effect on reservoir yield and operation practices. Severe intensity rainfall events can cause failure of drainage system capacity and subsequent urban flood inundation problems. Policy makers, end users and leading researchers need to work together to develop a consistent approach to interpreting the effects of climate variability and change on water resources. This Special Edition includes papers by international experts who have investigated climate change impacts on a variety of systems including irrigation and water markets, land use changes and vegetation growth, lake water levels and quality and sea level rises. These investigations have been conducted in many regions of the world including the USA, China, East Africa, Australia, Taiwan and the Sultanate of Oman.

This report represents a synthesis of joint research conducted by the Development Research Center of the State Council of the People's Republic of China (DRC) and the World Bank. Building on the track record of research collaboration between the World Bank and the DRC on issues such as urbanization, the objective of the study is to provide Chinese policy makers with detailed institutional and policy options to support water security in the country. This study fills a critical gap highlighted in the World Bank 2013 China Country Water Resources Assistance Strategy by proposing legal, technical, and institutional changes to the current framework for water resource management. A new water governance approach is recommended that aims to balance economic growth with increasing water demand under conditions of water scarcity. By closely examining key water management issues in the context of China's rapid development, the study also aims to provide lessons relevant to other low- and middle-income countries facing similar water-related challenges. The report identifies five priority areas for reform: 1) Enhance the legislative foundation for water governance; 2) Strengthen national and basin-level water governance; 3) Improve and optimize economic policy instruments; 4) Strengthen adaptive capacity to climate and environmental change; and 5) Improve data collection and information-sharing.
