The Economics of Estuary Restoration in South Africa

About this book

This book examines the economic costs and benefits of the ecological restoration of estuaries, utilizing case studies from South Africa.

Estuaries are important ecosystems from both an ecological and human perspective. Yet, in many parts of the world they are often degraded environments, facing threats from climate change, invasive species, fire and wastewater pollution. While the environmental benefits of restoring degraded environments are well discussed, this book specifically examines the economic benefits of doing so. It applies a cost-benefit analysis, which focuses on a range of key ecosystem services, including human health, fishing value, recreational value and property value. The book utlizes three detailed studies of the Swartkops estuary, the Great Brak estuary and the Knysna estuary in South Africa, but also draws out lessons that can be applied to coastal environments across the world. Overall, this book demonstrates that ecological restoration does pay and that the value of additional ecosystem services gained through restoration far exceeds the costs associated with this restoration process.

This book will be of great interest to students and scholars of environmental management and restoration, ecological economics, ecosystem services and environmental conservation.
