Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell Nov 2016

Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell

Journal of Geospatial Applications in Natural Resources

Prescribed burning is used in West Virginia, USA to return the important disturbance process of fire to oak and oak-pine forests. Species composition and structure are often the main goals for re-establishing fire with less emphasis on fuel reduction or reducing catastrophic wildfire. In planning prescribed fires land managers could benefit from the ability to predict mortality to overstory trees. In this study, wildfires and prescribed fires in West Virginia were examined to determine if specific landscape and terrain characteristics were associated with patches of high/moderate post-fire change. Using the ensemble machine learning approach of Random Forest, we determined that …


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 …


Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer Jun 2016

Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer

Suburban Sustainability

Suburban and urban communities in the American West are challenged by rapid population growth combined with limited natural resources. Supporting sustainable development is of great concern in this region and in similar regions throughout the world. This research examines the sustainability of the water supply within a rapidly growing suburban city in the American West. The city, Rio Rancho, New Mexico, began as an interstate land sales operation and rapidly became a “boom” town, in part because of its location near metropolitan Albuquerque.

Because of a very limited water supply and an increasing demand for water associated with population growth, …


Marine Sciences At The University Of Maine, 1960-2015, Catherine Schmitt, Shelby Hartin Jun 2016

Marine Sciences At The University Of Maine, 1960-2015, Catherine Schmitt, Shelby Hartin

Maine History

The development of marine science research, teaching, and service at the University of Maine formally began in 1965, when Ira Darling and Clare Shane Darling transferred their 127-acre farm and woodlot on the Damariscotta River in South Bristol to the University. Their express purpose was to establish a marine laboratory. The gift fulfilled the decades old desire by University of Maine scientists and administrators to do just that. UMaine quickly began hiring faculty, starting research projects, building structures, developing courses, and creating ties to state and federal agencies. The transition from farm to world-class facility and laboratory was gradual, with …


The Effect Of Marine Protected Areas On Fishers' Income In The Philippines, Giselle Pb. Samonte, Victoria C. Ramenzoni, Terence U. Dacles, Dominik Fortenbacher May 2016

The Effect Of Marine Protected Areas On Fishers' Income In The Philippines, Giselle Pb. Samonte, Victoria C. Ramenzoni, Terence U. Dacles, Dominik Fortenbacher

Journal of Ocean and Coastal Economics

The fisheries sector is vital to the Philippine economy, providing substantial employment and income, contributing export earnings, and meeting local food security and nutrition requirements. To protect coastal and marine habitat and to sustain fisheries, over 1000 marine protected areas (MPAs) have been established, in the Philippines. This paper provides empirical evidence on the variance of net revenues linked with MPA establishment and the possible range of relocation costs for fishing effort displaced by an MPA. A total of 424 households were randomly selected from 18 barangays (villages) adjacent to MPAs in three regions in the Philippines. Results show that …


Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk May 2016

Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk

Journal of Ocean and Coastal Economics

Seagrass meadows (Zostera marina) are an important ecosystem in the coastal environment of the Baltic Sea. This study employs a discrete choice experiment to value a set of non-market benefits provided by seagrass meadows in the Gulf of Gdańsk, Poland. The benefits valued in this study are a reduction of filamentous algae in the water and on the beach; access to seagrass meadows for boaters and divers; and improved water clarity. Results show significant willingness to pay for each attribute and differences of value estimates across different groups of survey respondents. It is discussed how to link choice …


From The Orderly World Of Frameworks To The Messy World Of Data: Canada’S Experience Measuring The Economic Contribution Of Maritime Industries, Alejandro De Maio, Christine Irwin Feb 2016

From The Orderly World Of Frameworks To The Messy World Of Data: Canada’S Experience Measuring The Economic Contribution Of Maritime Industries, Alejandro De Maio, Christine Irwin

Journal of Ocean and Coastal Economics

This paper extends the frameworks developed by Park and Kildow (2014) to explore the use of supply chains to classify and organize ocean industries. Canada’s experience with measuring the economic contribution of ocean related sectors is discussed; with particular emphasis on illustrating the supply chain approach and of highlighting the multiple practical challenges that arise in defining and measuring the ocean economy. The overall conclusion is that Canada has succeeded in developing a methodological framework that allows it to report, on an annual basis high level estimates of gross domestic product, employment and labour income generated directly and indirectly by …


The New Blue Economy: The Future Of Sustainability, Mark J. Spalding Feb 2016

The New Blue Economy: The Future Of Sustainability, Mark J. Spalding

Journal of Ocean and Coastal Economics

The world’s ocean is the world’s life support. Many human activities have defined a negative relationship with the ocean. Simply put: we dump too much bad stuff in, and we take too much good stuff out. The traditional ocean economy—those ocean-based and ocean-related activities from which humans derive economic benefit— did not acknowledge or honor the ocean’s natural services, nor its finite capacity to take human abuse without undermining those services on which we depend. The “new blue economy” is the term of art for identifying those activities that improve the human relationship with the ocean and for aligning our …


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 …


Ocean Economy Valuation Studies In The Asia-Pacific Region: Lessons For The Future International Use Of National Accounts In The Blue Economy, Alistair Mcilgorm Feb 2016

Ocean Economy Valuation Studies In The Asia-Pacific Region: Lessons For The Future International Use Of National Accounts In The Blue Economy, Alistair Mcilgorm

Journal of Ocean and Coastal Economics

There have been several projects that have addressed the challenges of measuring the ocean economy in the Asia-Pacific region. The paper examines some lessons from these projects and the implications for the future use of national accounts.

Following the Asia Pacific Economic Cooperation (APEC) Bali declaration, the APEC Marine Resource Conservation Working group’s “Measuring the Marine economy” project promoted consistent measurement of the marine economy across the 21 APEC economies against a list of agreed marine industry categories which was developed by an APEC workshop on Easter Island in 2004.

In 2008-09 a Partnership for the Environmental Management of the …


Accounting For The Ocean Economy Using The System Of National Accounts, Raymundo J. Talento Feb 2016

Accounting For The Ocean Economy Using The System Of National Accounts, Raymundo J. Talento

Journal of Ocean and Coastal Economics

The increasing importance to measure the ocean economy cannot be discounted. A number of countries attempted to measure the ocean economy based on their needs and perceptions. At this point, however, there is no agreed scope and coverage of the ocean economy nor is there an agreed operational definition of the variables needed for its measurement. Moreover, there is no internationally endorsed framework that will guide and lead to comparable estimates across countries or regions.

Utilizing the 2008 System of National Accounts (SNA) as a framework, this paper endeavors to estimate the contribution of the ocean economy in the Philippines …

The Role Of Economics In Ecosystem Based Management: The Case Of The Eu Marine Strategy Framework Directive; First Lessons Learnt And Way Forward., Soile Oinonen, Tobias Börger, Stephen Hynes, Ann Katrin Buchs, Anna-Stiina Heiskanen, Kari Hyytiäinen, Tiziana Luisetti, Rob Van Der Veeren

Journal of Ocean and Coastal Economics

The EU Marine Strategy Framework Directive (MSFD) sets out a plan of action relating to marine environmental policy and in particular to achieving ‘good environmental status’ (GES) in European marine waters by 2020. Article 8.1 (c) of the Directive calls for ‘an economic and social analysis of the use of those waters and of the cost of degradation of the marine environment’. The MSFD is ‘informed’ by the Ecosystem Approach to management, with GES interpreted in terms of ecosystem functioning and services provision. Implementation of the Ecosystem Approach is expected to be by adaptive management policy and practice. The initial …


Maritime Accounts In The European Union: Coping With Limited Information, Regis Kalaydjian Feb 2016

Maritime Accounts In The European Union: Coping With Limited Information, Regis Kalaydjian

Journal of Ocean and Coastal Economics

The European Commission's effort to define the scope and components of the maritime economy was initially motivated by the "Integrated Maritime Policy" (2007). This policy package, principally based on coastal environment protection, maritime safety and security, and the European marine observation and data network, also included the development of an EU-wide economic and social database on maritime activities. The IMP database (2009) used experience from EU member states in terms of maritime database development, and conversely was an opportunity to update national contributions.

Later, two other packages contributed to broadening EC's approach. 1) The "Marine Strategy Framework Directive" (2008) was …

Spatial Analysis Of Forest Crimes In Mark Twain National Forest, Missouri, Karun Pandit, Eddie Bevilacqua, Giorgos Mountrakis, Robert W. Malmsheimer Jan 2016

Spatial Analysis Of Forest Crimes In Mark Twain National Forest, Missouri, Karun Pandit, Eddie Bevilacqua, Giorgos Mountrakis, Robert W. Malmsheimer

Journal of Geospatial Applications in Natural Resources

Forest crime mitigation has been identified as a challenging issue in forest management in the United States. Knowledge of the spatial pattern of forest crimes would help in wisely allocating limited enforcement resources to curb forest crimes. This study explores the spatial pattern of three different types of forest crimes: fire crime, illegal timber logging crime, and occupancy use crime in the Salem-Patosi Ranger District of Mark Twain National Forest. Univariate and bivariate Ripley’s K-functions were applied to explore the spatial patterns in crime events, like clustering and attraction among forest crime types. Results reveal significant clustering for each forest …


Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover Jan 2016

Comparison Of Terrain Indices And Landform Classification Procedures In Low-Relief Agricultural Fields, Derek A. Evans, Karl W. J. Williard, Jon E. Schoonover

Journal of Geospatial Applications in Natural Resources

Landforms control the spatial distribution of numerous factors associated with agronomy and water quality. Although curvature and slope are the fundamental surface derivatives used in landform classification procedures, methodologies for landform classifications have been performed with other terrain indices including the topographic position index (TPI) and the convergence index (CI). The objectives of this study are to compare plan curvature, the convergence index, profile curvature, and the topographic position index at various scales to determine which better identifies the spatial variability of soil phosphorus (P) within three low relief agricultural fields in central Illinois and to compare how two methods …


Discordant Data And Interpretation Of Results From Wildlife Habitat Models, Anita T. Morzillo, Michael G. Wing, Justin Long Jan 2016

Discordant Data And Interpretation Of Results From Wildlife Habitat Models, Anita T. Morzillo, Michael G. Wing, Justin Long

Journal of Geospatial Applications in Natural Resources

Wildlife habitat management is an important part of natural resource management. As a result, there are a large number of models and tools for wildlife habitat assessment. A consequence of the many assessment tools is inconsistency when comparing results between tools, which may lead to potential confusion management decisions. Our objective was to compare results from two wildlife habitat models – one being relatively coarse (HUC5) scale and not spatially dynamic and the other being finer scale spatial data based on a 30 m spatial resolution –for habitat assessment of three species across the West Cascades of Oregon: Northern spotted …


Picking Up The Slackline: Can The United States And Japan Successfully Regulate Commercial Fishing Of Bluefin Tuna Following Failed Intergovernmental Attempts?, Sarah E. Bauer Jan 2016

Picking Up The Slackline: Can The United States And Japan Successfully Regulate Commercial Fishing Of Bluefin Tuna Following Failed Intergovernmental Attempts?, Sarah E. Bauer

Indiana Law Journal

Part I of this Note will address the reasons why intergovernmental organizations have failed to adequately regulate the commercial fishing of Bluefin tuna. Part II offers an analysis of the Bluefin markets in the United States and Japan and argues that these countries are ideal candidates for successful Bluefin regulation because of their market structures. Part III explores the likelihood that the two countries would implement such regulations, taking into account the respective governments’ histories of species-specific regulation.


Plain Facts About Anthropogenic Global Climate Change And Warming: A Review, M. K. Cleaveland Jan 2016

Plain Facts About Anthropogenic Global Climate Change And Warming: A Review, M. K. Cleaveland

Journal of the Arkansas Academy of Science

Anthropogenic global climate change (AGC) is proceeding rapidly. The proximate cause is the greenhouse effect of carbon dioxide, methane and other greenhouse gases (GHG), which have rapidly accumulated in the atmosphere from burning fossil fuels and other human activities. Measurements of incoming and outgoing radiation have verified the warming imbalance. Effects manifest themselves in accelerating sea level rise and diminishment of the cryosphere. This has already created climatic refugees and water stress, and will destroy coastal infrastructure. It also impacts ecosystems and biodiversity in many ways. To avoid catastrophic effects, fossil fuel use must cease and carbon sinks must be …
