The Mekong Delta Environmental Research Guidebook, Volume Four comprehensively covers the Mekong Delta and presents new evidence on unsolved environmental issues. Key experts from around the world offer suggestions for the implementation of more effective mitigation and adaptation measures, especially in the context of climate change and upstream hydropower dam development. This book will help guide students and scientists, both juniors and seniors in their journey of the Mekong Delta Environmental Research, by presenting them with all the necessary information and detailed case studies for a more in-depth understanding of each issue so they can make informed decisions.
