Natural resources are necessary for meeting simple human needs such as food, water, clothing, shelter, and air. They are part of humanity's natural heritage or protected in nature reserves. Therefore, sustainable management of natural resources is crucial to ensure the stability of the ecosystem, prevent further damage to the environment, and avoid over-consumption of the resources. For the United Nations' Sustainable Development Goals (SDGs) to be achieved, it is crucial that natural resources be protected from being destroyed or overused. In addition, proper care of these resources will help them sustain for a long period of time to meet the needs of future generations. The global community has become increasingly aware of the importance of sustainable natural resources management. As highlighted in this book, it can be achieved through multiple approaches of top-down, adaptive management, integrated natural resources management, and community-based resources management. This book discusses the theories, practices, and findings on effective natural resource management being practiced in many parts of the world.
