Ecosystem-based management (EBM) refers to an integrated and science-based approach which emphasizes on the management of natural resources. It focuses on maintaining the resilience, health and diversity of ecosystems that enables humans to utilize the products and services they offer in a sustainable manner. EBM is an adaptive method to manage human activities that seeks to ensure the coexistence of healthy, fully functioning ecosystems and human societies. It can be used to study both terrestrial and marine ecosystems along with the challenges they pose. Marine EBM aims to manage marine resources in a way that safeguards ecosystem health in order to provide the ecosystem services required by people. This book aims to shed light on the applications of ecosystem-based management. It will also provide interesting topics for research which interested readers can take up. The book will serve as a valuable source of reference for graduate and postgraduate students.
