MINOE: A Software Tool to Analyze Ocean Management Efforts in the Context of Ecosystems

Transitioning ocean governance into an integrated ecosystem-based approach requires improved knowledge of existing governance arrangements. This article presents a software tool, MINOE, to assist policymakers, scientists, and others involved in ecosystem-based management initiatives to navigate through management documents as they relate to a user-defined ecosystem. The tool uses a conceptually modeled ecosystem, defined by the user, and text analysis of a set of management-related documents to determine which ecosystem linkages are potentially acknowledged in the documents. For illustration, the set of documents included with MINOE currently (and used to demonstrate the software in this article) are laws and regulations from four geopolitical jurisdictions for the year 2006; however, users may also import other documents for a more tailored application. Features include an interactive matrix containing results about the set of management documents within the user's scope and scale of interest. In addition, MINOE includes metrics and visualization tools to synthesize information derived from the documents. The article presents the software tool, describes potential uses for the tool, and ends with a discussion of future work to expand the program.     

Transaction Costs of Community-Based Coastal Resource Management: The Case of San Miguel Bay,Philippines

This study estimates and analyzes the transaction costs (TC) associated with the implementation of a multilevel and multistakeholder program such as a community-based coastal resource management program. Results show that TC accounted for 37% of the total project cost (TPC). The instability of financial support resulted in high TC, which was estimated to be 86% of the TPC during the implementation phase of the coastal resource management projects. The share of the total TC was highest among the people's organizations (POs) that were the beneficiaries of the program. The number of people involved in the transactions, the number of activities undertaken, and the success index of the POs were among the factors significantly affecting the TC. Analysis also shows that while higher TC led to higher success index of the POs at the initial stage of the project implementation, an increasing level of TC eventually slowed down their performance.     

Preface and Acknowledgments

Abstract

The term “mitigation”; has been used in connection with habitat losses attributable to federal water projects as early as the Rivers and Harbors Act of 1899 and the Fish and Wildlife Coordination Act of 1934. Most of the current requirements to mitigate habitat losses associated with water development projects apply to wetlands, as they are biologically productive and have been destroyed at an increasing rate during recent years by developers seeking prime land in the coastal zone. A case study of the Port of Coos Bay and the City of North Bend, Oregon, provides an actual experience of estuarine mitigation in a dredging project and an airport fill. The case was developed as part of a larger curriculum research study for seaport management. This article is primarily written as a case with a brief introduction and discussion of mitigation requirements, followed by the text of the case and ending with a series of hypotheses for further research.     

Development of Beach Analysis Tools for Caribbean Small Islands

Beach erosion presents a hazard to coastal tourism facilities, which provide the main economic thrust for most Caribbean small islands (CSIs). Ad hoc approaches to addressing this problem have given way to the integrated coastal zone management (ICZM) approach, which recommends data collection, analysis of coastal processes, and assessment of impacts. UNESCO's Coast and Beach Stability in the Caribbean (COSALC) project has provided most CSIs with an opportunity to monitor their beaches and collect over 10 years of data. Research has been directed at integrating these data with geographic information systems (GIS) and other information technologies to develop a prototype beach analysis and management system (BAMS) for CSIs. This article presents the results of phase I development of this effort, which includes the development of tools for integrating spatial and non-spatial coastal data, estimating long-term beach erosion/accretion and sand volume change trends at individual beaches, identifying erosion-sensitive beaches, and mapping beach erosion hazards. The Southeast Peninsula, St. Kitts, is used as a case study to develop these tools and demonstrate system functionality.     

State ocean policy initiatives in Florida

Abstract

A territorial sea comprising 6.7 million acres of offshore lands extending three geographic miles into the Atlantic Ocean three marine leagues (nine geographic miles) into the Gulf of Mexico makes Florida the second largest “oceanowning”; state in the contiguous United States. Florida's history, climate, economic development, and worldwide reputation have evolved from the state's relationship with the sea. The state is now becoming aware that aggressive management of its ocean resources is necessary to preserve the future of that relationship. The purpose of this article is to present some of Florida's recent legal and policy initiatives that have been directed toward better understanding and management of ocean resources and uses.

Regional fishery management councils: The federal perspective

Abstract

Under the Magnuson Fishery Conservation and Management Act of 1976, the federal government cooperates with states, the fishing industry, and public constituencies to regulate fisheries. This paper notes changes in U.S. fisheries over the last decade, remarks on the effectiveness of the Act, and makes suggestions for an improved fishery management process.

The Necessity of Establishing a Regional Marine Research Program for the U.S. West Coast

The welfare of the marine environment of the U.S. West Coast of California, Oregon, and Washington is hindered by insufficient understanding of ecosystem dynamics and human pressures. Greater coordination, integration, and support of mutually identified research priorities across research organizations on the West Coast are necessary. This level of collaboration is essential to responding to regional ecosystem threats, such as the impacts of human occupation of coastal areas, over-harvesting of marine resources, and climate change. To address this need for collaboration and build on the accomplishments of existing research organizations, this article advocates the establishment of a West Coast regional marine research program (RMRP).

Marine Shoreline Management—A 35-Year Evaluation of Outcomes in San Juan County,Washington, US

In 1976, Washington became the first state to implement the federal Coastal Zone Management Act (CZMA) primarily through the 1971 WA Shoreline Management Act (SMA). However, there has been little effort in Washington to evaluate outcomes of shoreline protection programs post SMA. In 2006–2008, we characterized shoreline conditions in San Juan County over three time periods spanning pre and post SMA and engaged community members to improve effectiveness of shoreline protection. We found modest improvements in forest retention on marine shorelines between pre and post 1977, but few other improvements through time. While we could not measure shoreline construction rates, construction practices for shore armor and overwater structures (docks) have changed very little, despite the increased regulatory standards. The vast majority of shore armor constructed post SMA occurred without mandatory county or state permits likely due to: widespread perception that permits were unnecessary and that permit standards were arbitrary and inconsistently applied; poor understanding of shoreline ecology by community members; lack of county or state enforcement authority and shoreline monitoring programs; and poor permit tracking systems.
