This new reference book covers the important topics of our current time-the impact of climate change and urban environment sustainability, using empirical and theoretical insights. It studies the meaningful connectivity between water security and energy conservation. This volume also reports on the relationship between climate change and environment sustainability with emphasis on comparative case studies, providing a broad overview of interconnection between sustainability alongside population growth, rising living standards, and increasing demand on the consumption of water and energy. It draws the attention of readers to the inter-linkage of climate change and the two sectors of water and energy that are very essential for sustainable environment goals.
