This book investigates the close relationship between ecosystems and water resources, emphasising how the availability, quality, and management of water influence environmental sustainability and human well-being. It presents water not merely as a natural resource, but as a fundamental component of ecological balance, agricultural productivity, and social development. The text examines the movement and distribution of water through natural and managed systems, highlighting the challenges associated with resource scarcity, pollution, infrastructure demands, and environmental degradation. It also considers the impact of human activities on aquatic environments, including the effects of waste disposal, land-use practices, and chemical contaminants on water quality and ecosystem health. Special attention is given to watershed-based approaches and groundwater restoration strategies, illustrating how integrated management can improve resource efficiency and environmental resilience. Through scientific discussion and practical perspectives, the book demonstrates the importance of coordinated planning in protecting water-dependent ecosystems.

The book aims to provide readers with a comprehensive understanding of water-resource management and ecological sustainability, supporting informed decision-making and responsible stewardship of water systems in both natural and managed environments.
