Climate change and human activities are impacting the environment around the world and there is a great need to update our knowledge of natural resources in order to sustain the livelihoods of rural communities and urban dwellers. Educational tools help people to understand the ecology, and the management of natural resources and to participate in actions to protect the environment. This book has a multipurpose focus regarding biodiversity, management, and conservation of the natural resources as species are linked in nutritional webs in the ecosystems. Ecology, diversity, conservation, and management practices such as plant species, native fish, edible mushrooms, and woody species are important for improving people livelihoods and incomes. It is expected that readers will learn to apply similar multipurpose approaches to natural resources in other parts of the world when their environments are affected by climate change or human activities.
