World Heritage requires sustainable conservation via effective protection and management involving planning, implementation and on-going phase; however there is a blank pool in the academic field concerning the holistic system of 'on-going phase'. Additionally given the most distinctive characteristics in Asian-Pacific region, the sustainability of cultural heritage is confronted with severe challenges in the process of globalization. That's why this book puts forward two questions: How to deal with challenges of unsustainable development for heritage conservation on a regional scale? How to make it happen in Asian-Pacific region? This book, therefore, builds an operational model to ensure the positive cycling of 'on-going phase' for heritage conservation both in short and long terms. This book also proves the feasibility of this model through a case study of cultural heritage in Asian-Pacific region via primary data for analysis. In anticipation of this book, the analysis should help stakeholders take actions to cope with relevant issues in the cultural heritage sites, or shed some light for anyone who is interested in heritage preservation, management and sustainable development.
