Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood
Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood
Journal of Ocean and Coastal Economics
Disease and overfishing have led to a dramatic decline in wild populations and subsequent harvests of the eastern oyster Crassostrea virginica over the past few decades in Delaware and other states along the Atlantic Coast. However, in addition to their value as food to consumers, oysters, whether wild populations or cultured stocks, can provide ecosystem services such as nutrient removal, which may result in localized water quality improvements. Consequently, recent policies in Delaware have sought to establish and grow an oyster aquaculture industry. However, a key challenge to achieving efficient levels of industry growth and water quality improvements is that …
Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan
Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan
Journal of Ocean and Coastal Economics
The widespread efforts to incorporate the economic values of oceans into national income accounts have reached a stage where coordination of national efforts is desirable. A symposium held in 2015 began this process by bringing together representatives from ten countries. The symposium concluded that a definition of core ocean industries was possible but beyond that core the definition of ocean industries is in flux. Better coordination of ocean income accounts will require addressing issues of aggregation, geography, partial ocean industries, confidential, and imputation is also needed. Beyond the standard national income accounts, a need to incorporate environmental resource and ecosystem …
Economic Assessment Of Oceans For Sustainable Blue Economy Development, Maria Corazon M. Ebarvia
Economic Assessment Of Oceans For Sustainable Blue Economy Development, Maria Corazon M. Ebarvia
Journal of Ocean and Coastal Economics
This paper presents the common approach on blue economy assessment adopted by selected countries in the East Asian Seas region, and results of initial assessment studies. There are many discourses on the definition and scope of blue economy as the ocean space is evolving, driven by innovations, shifting demands, and pressures from changing environment and climate. The ocean economy contributes to the GDP of the EAS countries in varying degrees: 3 % in RO Korea, 4.5 % in the Philippines, 9 % in China, and 13 % in Indonesia. In addition to the ocean economic activities, the ocean also generates …
The Evolution Of Non-Market Valuation Of U.S. Coastal And Marine Resources, Douglas Lipton, Dan K. Lew, Kristy Wallmo, Peter Wiley, Anthony Dvarskas
The Evolution Of Non-Market Valuation Of U.S. Coastal And Marine Resources, Douglas Lipton, Dan K. Lew, Kristy Wallmo, Peter Wiley, Anthony Dvarskas
Journal of Ocean and Coastal Economics
At the federal level, particularly within the National Oceanic and Atmospheric Administration (NOAA), regulatory and programmatic needs have driven the continued development and application of non-market valuation approaches to marine and coastal resources. The evolution of these valuation approaches not only entails adopting the recommendations of the 1993 NOAA blue ribbon panel on contingent valuation, but also an expansion of stated preference approaches with increased use of stated preference choice experiments. Revealed preference approaches have also advanced with more sophisticated random utility models. We provide an overview of this evolution in the areas of natural resources damage assessment, protected resources, …
What Have We Learned From The Deepwater Horizon Disaster? An Economist’S Perspective, Daniel R. Petrolia
What Have We Learned From The Deepwater Horizon Disaster? An Economist’S Perspective, Daniel R. Petrolia
Journal of Ocean and Coastal Economics
This paper outlines what we have learned about the impacts of the Deepwater Horizon (DWH) oil disaster from the economics discipline as well as what effect the DWH disaster has had on the economics discipline. It appears that what we know about the economic impact of the DWH spill today is limited, possibly because such analysis is tied up in the federal Natural Resource Damage Assessment (NRDA) process and other state-led efforts. There is evidence, however, that the NRDA process has changed over time to de-emphasize economic valuation of damages. There is also evidence that economists may be producing fewer …
