This book unveils the ground-breaking technological advancements in natural environmental protection and pollution treatment, encompassing research spanning from the natural environment preservation, water pollution control, risk assessment, policies, nexus approach, and their related areas. According to the October 2023 report by the World Health Organization (WHO), approximately 10% of the global population continues to consume food irrigated by wastewater. Alarmingly, nearly 3.47 billion people reside in environments affected by untreated wastewater, leading to severe human health risks and life-threatening conditions. Water resource management remains a critical concern in the realm of environmental safety, garnering substantial attention from different regions of the world.

To address the global concern, smart water resilience framework appears to be most relevant approach, as it addresses emergent issues related to optimization, treatment, and reuse of all available water sources in a timely and achievable manner while creating opportunities for commercial advantage paving the way for long-term sustainability. This realignment can be achieved by reassessing the current products and services; improving water use efficiency by pursuing the possibilities for water recycling or reuse within industrial processes and domestic activities; establishing sustainable environmental management systems related to natural water courses, or built environment for environmental preservation and public health improvement; improving the existing governance policies related to wastewater treatment, management strategies, and smart partnerships; and implementing better resource allocation and management.

This book seeks to offer valuable insights and share successful experiences among scholars, engineers, and environmental professionals from the world's leading universities, research centers, and governmental and industrial departments engaged in environmental management, catering especially to regions and countries grappling with ongoing wastewater pollution issues.
