Water resources are sources of water, such as groundwater, rivers, springs, streams, reservoirs and lakes that are beneficial for human beings. The variability of these water resources is affected by climate change, which results in shifts in weather and temperature patterns. The rise in temperature has an impact on the hydrological cycle, as it increases the rate of evaporation of the surface water along with vegetation transpiration. The primary effects of climate change on water resources are an increase in the frequency of droughts and floods, increased temperature, decreasing snow cover and wildfires. As a result, it affects the water storage in the sub-surface and surface reservoirs. The building of resilient societies and ecosystems involves dealing with the present challenges of water crisis and climate change by adopting sustainable water management strategies. This book unfolds the impact of climate change on water resources. It consists of contributions made by international experts. This book is meant for students who are looking for an elaborate reference text on the challenges and solutions related to an imminent water crisis.
