The aim of this research is to estimate how much Palauan people value coral reefs in the Rock Island Southern Lagoon (RISL) in Palau by using the Contingent Valuation Method, which is one of the methods used in Environmental Economics. According to some surveys, Palauan people are comparatively more environmentally-conscious than those from other countries. However, in recent years, land development has been rapidly increased, and the number of tourists has been drastically increasing as well. Climate change is a global phenomenon that is affecting the condition of the marine environment. These trends cause serious damages to the natural environment. Since coral reefs provide some of the most important resources to the Palauan people, we conducted this study to understand the value of coral reefs to the people of Palau, and as a result develop appropriate and effective conservation policy for Palau’s coral reefs. As a result of CVM survey conducted in Koror and Airai states, people’s “Willingness to Pay” and “Willingness to Work” is estimated at $8.00 (USD)per month with a total annual value that is estimated at $452,448 (USD). These estimated values can be used as critical information for compensation for coral damage, evaluation of economic efficiency of conservation policy, and improving awareness or education for Palauan residents.
This collection of essays presents insight and methodology that are highly relevant for readers today as they consider the future of the world they live in. Experiencing the COVID-19 pandemic, people have realized how fragile the current economy is and the necessity for reconstructing the socio-economic system. That system, which was considered the default for so long, was succeeded by the analytical framework of economics and regional science. The contents of this book are diversified, as are the achievements of Prof. Yasuhiro Sakai, to whom this volume is dedicated, and cover a wide area from mathematical and experimental economics to conventional and emerging fields of regional science. Some are timeless topics that have had new life breathed into them. Part I deals with, among other areas, risk management with uncertain events; the effectiveness and impacts of regulation and friction related to trading; the stability of strategic behavior and market equilibrium; and sustainable regional development and urban planning from the long-term perspective. Part II also presents a diversity of subjects, including input–output analysis and computable general equilibrium (CGE) modelling for internal as well as external structure and network linkage, such as a value chain; openness and creativity as related to competition among cities and regions; dispersion versus concentration; and inequality versus equality.
This open access book summarizes peer-reviewed articles and the abstracts of oral and poster presentations given during the YOUMARES 9 conference which took place in Oldenburg, Germany, in September 2018. The aims of this book are to summarize state-of-the-art knowledge in marine sciences and to inspire scientists of all career stages in the development of further research. These conferences are organized by and for young marine researchers. Qualified early-career researchers, who moderated topical sessions during the conference, contributed literature reviews on specific topics within their research field. .
This volume investigates the effects of human activities on coral reefs, which provide important life-supporting systems to surrounding natural and human communities. It examines the self-reinforcing ecological, economic and technological mechanisms that degrade coral reef ecosystems around the world. Topics include reefs and limestones in Earth history; the interactions between corals and their symbiotic algae; diseases of coral reef organisms; the complex triangle between reef fishes, seaweeds and corals; coral disturbance and recovery in a changing world. In addition, the authors take key recent advances in DNA studies into account which provides new insights into the population biology, patterns of species distributions, recent evolution and vulnerabilities to environmental stresses. These DNA analyses also provide new understandings of the limitations of coral responses and scales of management necessary to sustain coral reefs in their present states. Coral reefs have been essential sources of food, income and resources to humans for millennia. This book details the delicate balance that exists within these ecosystems at all scales, from geologic time to cellular interactions and explores how recent global and local changes influence this relationship. It will serve as an indispensable resource for all those interested in learning how human activities have affected this vital ecosystem around the world.

Corals and coral reefs are seriously degraded in most tropical seas. Most of the damage is due to over-exploitation and the use of destructive fishing methods. This collection of essays presents a number of case studies on the economic analysis of coral reefs.
