Climate change adaptation is a new challenge for vulnerable societies such as China, and I am honored to be involved in finding solutions for China’s development dilemma. As an indispensable response to adaptation issues, our legal system is expected to be developed for better resilience and higher adaptive capacity. Yet, as a legal issue, climate change adaptation is distinguished from traditional environmental problems and mitigation in a variety of ways. Its legal challenges to extant regulations and regimes need to be clarified and profoundly understood before possible legal responses are proposed, and before a brand new Climate Change Law is enforced. All my past five years of reflection and research has been centered with these questions and this book marks the culmination of it. Wuhan University has always been an important place for me, since it is there my academic journey set sail and my life was greatly enriched. Professor Ke Jian of Wuhan University has kindly been my mentor of both academic dedication and personal life in the past seven years. His vision and passion for environmental law, his sympathy for those marginalized, and his perseverance of academic independence have influenced me in various ways. I would also like to show gratitude to Prof. Xia Jun from the Chinese Academy of Science. Without his help of introducing some key government officials to me, I could not conduct effective interviews and field visits in order to get fresh information on adaptation for the completion of this book.
