Journal of Ocean and Coastal Economics

Availability and easy access to a wide range of natural and human-activity data on the oceans and coastal regions of Europe is the basis for strategic decision-making on coastal and marine policy. Strategies within Europe’s Integrated Maritime Policy, including the Maritime Strategy for the Atlantic Area, Blue Growth, Maritime Spatial Planning and Marine Data and Knowledge, require coherent and comparable socio-economic data across European countries. Similarly, the Marine Strategy Framework Directive requires member states to carry out economic and social analysis of their waters and the reformed Common Fisheries Policy includes a social dimension requiring socio-economic data. However, the availability …

Assessing The Economic Costs Of Water Pollution In The Yangtze River, China, Xiaoli Zhang

Journal of Ocean and Coastal Economics

Water pollution of the Yangtze River basin is very serious. Studies have shown that from the upper to the lower river, the water volume decreases and development and pollution increase, especially in trans-boundary areas. The Yangtze Estuary is located at the intersection of Jiangsu Province and Shanghai where the waters flow directly into the East China Sea. The estuary provides drinking water to many people and serves multiple other functions, including agricultural irrigation, tourism, and aquaculture. It plays a pivotal role in the local social and economic development and in people’s general wellbeing. Directly or indirectly, the pollution of the …

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 …

Nephrotoxic Contaminants In Drinking Water And Urine, And Chronic Kidney Disease In Rural Sri Lanka, Tewodros Rango, Marc Jeuland, Herath Manthrithilake, Peter G. Mccornick

Daugherty Water for Food Global Institute: Faculty Publications

Chronic kidney disease of unknown (“u”) cause (CKDu) is a growing public health concern in Sri Lanka. Prior research has hypothesized a link with drinking water quality, but rigorous studies are lacking. This study assesses the relationship between nephrotoxic elements (namely arsenic (As), cadmium (Cd), lead (Pb), and uranium (U)) in drinking water, and urine samples collected from individuals with and/or without CKDu in endemic areas, and from individuals without CKDu in nonendemic areas. All water samples—from a variety of source types (i.e., shallow and deep wells, springs, piped, and surface water)—contained extremely low concentrations of nephrotoxic elements, and all …

Yield Gap Analysis Of Field Crops: Methods And Case Studies, V. O. Sadras, Kenneth Cassman, Patricio Grassini, W. G.M. Bastiaanssen, A. G. Laborte, A. E. Milne, G. Sileshi, P. Steduto

Daugherty Water for Food Global Institute: Faculty Publications

The challenges of global agriculture have been analysed exhaustively and the need has been established for sustainable improvement in agricultural production aimed at food security in a context of increasing pressure on natural resources. Whereas the importance of R&D investment in agriculture is increasingly recognised, better allocation of limited funding is essential to improve food production. In this context, the common and often large gap between actual and attainable yield is a critical target. Realistic solutions are required to close yield gaps in both small and large scale cropping systems worldwide; to make progress in this direction, we need (1) …

Participatory Conservation Of Coastal Habitats: The Importance Of Understanding Homeowner Decision Making To Mitigate Cascading Shoreline Degradation, Steven B. Scyphers, Steven J. Picou, Sean P. Powers

University Faculty and Staff Publications

Along densely populated coasts, the armoring of shorelines is a prevalent cause of natural habitat loss and degradation. This article explores the values and decision making of waterfront homeowners and identifies two interlinked and potentially reversible drivers of coastal degradation. We discovered that: (1) misperceptions regarding the environmental impacts and cost-effectiveness of different shoreline conditions was common and may promote armoring; and (2) many homeowners reported only altering their shorelines in response to damage caused by armoring on neighboring properties. Collectively, these findings suggest that a single homeowner’s decision may trigger cascading degradation along a shoreline, which highlights the necessity …

Specifically, it describes the snail dredging activities done in selected areas in Laguna Lake, determines the profitability of snail dredging, and identifies the market destinations of the snails dredged. Snail dredging has been banned because of its adverse effects on the lake environment. However, the study finds that snail dredgers continue to operate all year round. On a daily basis, dredging operations range from 4 to 10 hours. Snails dredged from Laguna Lake are brought to the provinces of Pampanga …

Decoy Effect And Student Preference With Regard To Usb Flash Drives, Jeff Arapoc

Journal of Economics, Management and Agricultural Development

Standard economic theory assumes that individuals make decisions that are consistent across different choice situations. Behavioral economics challenges the standard economic theory account of individual behavior. This budding field suggests that consumer preference for one option over another changes as a result of adding another option. This study aims to determine the effect of a decoy option on consumer preference for USB flash drives. A quasi-experiment was conducted among 100 UPLB students wherein each respondent was initially asked to choose between two kinds of flash drive. The researcher then adds a decoy option to test if the respondent will change …

Farmers’ Willingness To Pay For An Alternative Irrigation Policy To Reduce Greenhouse Gas Emissions From Rice Farming In The Upper Pampanga River Integrated Irrigation System, Fezoil Luz C. Decena, Impa Buayon

Journal of Economics, Management and Agricultural Development

The practice of continuous flooding of rice fields in the national irrigation systems has attendant issues, including the inefficient use of water, unequal distribution of water along the irrigation canals, and greenhouse gas emissions. An ex-ante analysis was conducted to evaluate alternative policy options in the Upper Pampanga River Integrated Irrigation Systems, using both market and non-market approaches. The market approach estimated the greenhouse gas avoided and water savings due to the shift in policy. The non-market approach used choice experiment to estimate willingness to pay of farmers to shift the current to an alternative policy. The study concludes that …

Price Cointegration And Leadership In Regional Tilapia And Roundscad Markets In The Philippines,1990-2007, Yolanda T. Garcia

Journal of Economics, Management and Agricultural Development

This study aims to investigate the price dynamics between the wholesale and retail prices of roundscad and tilapia in the regional markets of the Philippines. It also seeks to analyze how the observed dynamics in these prices could be linked to the development in market-related infrastructures that can promote trade, e.g., telecommunication and transportation facilities. Results of the study reveal that there is a general decrease in the number of regions that show cointegrated wholesale and retail prices over time in both fish species. Moreover, price leadership under the “Granger-causality” sense (of either wholesale or retail price) seems to diminish …

Building Disaster Resilience To Address Household Food Security: The Case Of Sta. Rosa-Silang Subwatershed, Roberto F. Ranola Jr., Mi Cuesta, Bam Zaraf

Journal of Economics, Management and Agricultural Development

The Laguna Lake Region is one of the places in the Philippines that are most vulnerable to natural disasters because of their location and ecological condition. Among the natural calamities that regularly hit the country, one of the most frequent and disastrous is flooding. The most affected are the poor who are faced with the double risk of being food insecure and living in conditions that are very vulnerable to natural hazards. The most negative and long-term effect of flooding is reduction in food security because flooding erodes the asset base of households that in turn results in the adoption …

Investment analysis reveals that using the roaster for custom work would be a profitable business with an IRR of 76% …

Accuracy Or Precision: Implications Of Sample Design And Methodology On Abundance Estimation, Lucas K. Kowalewski, Christopher J. Chizinski, Larkin A. Powell, Kevin L. Pope, Mark A. Pegg

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Sampling by spatially replicated counts (point-count) is an increasingly popular method of estimating population size of organisms. Challenges exist when sampling by point-count method, and it is often impractical to sample entire area of interest and impossible to detect every individual present. Ecologists encounter logistical limitations that force them to sample either few large-sample units or many small sample-units, introducing biases to sample counts. We generated a computer environment and simulated sampling scenarios to test the role of number of samples, sample unit area, number of organisms, and distribution of organisms in the estimation of population sizes using N-mixture …
