"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 water security and the meaningful connectivity between water security and energy conservation. It has been demonstrated that water security and energy systems cannot be separated from the challenges associated with a sustainable environment. 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 with 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. This reference book explains what sustainable development is and how to achieve it. The book highlights environmental sustainability goals can be achieved through the development of green materials. For instance, green functionalized materials are used in energy science and pollution management for future technology development and can establish a sustainable society in harmony with nature"--
