Future Importance Of Healthy Oceans: Ecosystem Functions And Biodiversity, Marine Pollution, Carbon Sequestration, Ecosystem Goods And Services, Mohammad Mosharraf Hossain Oct 2019

Future Importance Of Healthy Oceans: Ecosystem Functions And Biodiversity, Marine Pollution, Carbon Sequestration, Ecosystem Goods And Services, Mohammad Mosharraf Hossain

Journal of Ocean and Coastal Economics

The paper provides a review the current status of ecosystem and resource extraction to provide a series of thoughts related to the future challenges in maintaining the health of the Marine and coastal ecosystems at the Bay of Bengal. The chapter highlighted the challenges current efforts and future interventions necessary to keep the Bay of Bengal large marine ecosystem healthy. They are mainly linked to climate change, environmental pollution from different sources, biodiversity conservation, sediment movement. marine spatial planning and adoption of protected area concept to design marine reserve, fish sanctuary and ecological critical areas in the coastal zone were …


Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood Jun 2019

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 …


Rethinking Our Global Coastal Investment Portfolio, Erin Mccreless, Michael W. Beck Mar 2017

Rethinking Our Global Coastal Investment Portfolio, Erin Mccreless, Michael W. Beck

Journal of Ocean and Coastal Economics

Coastal gray infrastructure, including roads, bridges, and buildings, is critical for communities, and we invest significantly in it. We also invest in the restoration and maintenance of coastal green infrastructure such as wetlands and reefs, which provide many services and benefits to human communities. However, the relative scale of financial investments in different coastal sectors – that is, our global coastal investment portfolio – remains poorly understood. We identify some of the major sources of funding for coastal green and gray infrastructure globally, including international aid funds; US public and private funds for coastal conservation, restoration and management; and private …


Measurement Of The Ocean Economy From National Income Accounts To The Sustainable Blue Economy, Charles S. Colgan Aug 2016

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 Feb 2016

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 …


Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill Oct 2015

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …


The Evolution Of Non-Market Valuation Of U.S. Coastal And Marine Resources, Douglas Lipton, Dan K. Lew, Kristy Wallmo, Peter Wiley, Anthony Dvarskas Feb 2015

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 Feb 2015

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 …
