This book presents a comprehensive introduction to environmental studies, exploring the dynamic relationship between humans and their natural surroundings. Structured to support students, educators, and policy thinkers alike, it delves into key ecological concepts, environmental degradation, natural resource management, and disaster response strategies. With a focus on the Indian context and supported by global perspectives, the book blends theoretical insights with real-life environmental concerns.

Beginning with the foundational concepts of ecology and environmental science, the text highlights the significance of preserving biodiversity, managing natural resources like water, forests, and minerals, and understanding the adverse impacts of human activities such as deforestation and pollution. It emphasizes the interconnectedness of biotic and abiotic components and the role of ecosystems in sustaining life.

The book explores pressing environmental issues such as climate change, water scarcity, soil erosion, habitat loss, and biodiversity reduction. It also discusses sustainable practices, conservation strategies, and the importance of public awareness in reversing environmental damage. Additionally, the sections on natural and human-made disasters shed light on causes, effects, and management strategies, offering insights into building resilience and mitigating risks.

Through case studies, statistics, and government initiatives, the book encourages critical thinking and informed decision-making. It aims to empower students with the knowledge and skills necessary to understand environmental challenges and contribute actively to sustainable development. The inclusion of self-evaluation tools at the end of each chapter enhances learning and retention, making it a valuable resource for academic study and practical application in environmental and disaster management domains.
