Economic Outcomes for Harvesters under the West Coast Groundfish Trawl Catch Share Program: Have Goals and Objectives Been Met?

Abstract

The West Coast Groundfish Trawl Catch Share Program was designed to achieve multiple economic goals and objectives, including increasing net benefits, profitability, flexibility, and utilization of harvest allocations. In this article, we leverage seven years of comprehensive cost and earnings data to evaluate progress towards these goals with a focus on harvesters. Our assessment shows that five years post-implementation, net benefits to the nation have doubled, and indicators of productivity and profitability have increased. The fleet that targets Pacific whiting has seen the largest gains, due in part to increases in total allowable catch and the elimination of the race-to-fish. However, increased revenues have not been realized to the degree that was expected for harvesters targeting non-whiting groundfish, partly due to lower than predicted consolidation and relatively low quota utilization. Economic outcomes indicate that tradeoffs exist between certain objectives of the program, specifically between achieving full utilization and flexibility for harvesters. Results are discussed in the context of the design and evaluation of catch share programs for diverse, multispecies fisheries.     

Shorebased Processor Outcomes Under Catch Shares

Abstract

Fishery management measures often aim to regulate harvesting behavior but can have downstream effects on fish processors, output markets, and consumers. Empirical analysis of these impacts is generally limited due to data availability. In this article, we utilize census costs and earnings data to examine operational characteristics and economic outcomes for shorebased processors before and after implementation of the West Coast Groundfish Trawl Catch Share Program. While the overall number of buyers of catch share species along the coast decreased and fish input prices generally increased, patterns in outcomes were different for processors with Pacific whiting operations compared to those that produce nonwhiting groundfish, including lengthened seasonal whiting operations but a decrease in the number of days receiving nonwhiting groundfish. These differences in outcomes illustrate the complexities involved in the management of multispecies fisheries with heterogeneous participants in both the harvest and post-harvest sectors. This review contributes to the fairly limited empirical work on the fish processing sector, which is an integral part of the seafood supply chain and important to the economic resilience of coastal fishing communities.     

A Review of Beach Bye-Law Usage in Supporting Coastal Management in Ireland

Coastal areas are commonly the focus of a range of human activities and uses. Beaches are one example of multi-use coastal environments, accommodating activities linked to leisure and recreation, amenity, conservation and business, often simultaneously. Ireland is no different in this regard, as its beach resources provide a range of goods and services of societal value. Ireland has 16 coastal counties and their associated local authorities have a beach management remit, a role that can present a number of challenges. The use of beach bye-laws is one option to support management of beach environments by local authorities. Local authority personnel tasked with beach management from each coastal local authority were surveyed to assess the actual and potential role of beach bye-laws in contributing to more effective management of beach environments and to broader coastal management. Usage of beach bye-laws varied across local authority areas and evidence suggested that the efficacy, use, and implementation of beach bye-laws differed from county to county. Beach bye-laws offer potential but interaction with other initiatives as part of a wider program for coastal management may yield improved results.     

Combined ships: an empirical investigation about versatility

Combined ships have been built in order to minimize ballast voyages and to take advantage of the highest freight rates on either market, oil or dry cargo market. Then their versatility should have been very attractive for shipowners. So why has the combined fleet shrunk to such an extent? This paper provides an analysis of the employment of combined ships, how this has been influenced since the 1970s, and how these ships may have influenced oil and dry market balances. The research identifies the decisive role that grain trade seems to be able to play about shifting markets, and that combined ships were the largest bulk carriers in the 1970s. It is an opportunity to stress that freight rates are not always the only salient point for a shipowner's decision and to consider the importance of combination ships contribution to shipping markets.     

Factors affecting mortality of vertebrates on the roads in the Czech Republic

This paper summarizes the results of monitoring animals killed by vehicles on selected roads in the Czech Republic as well as the circumstances of these accidents. Relationships between species of road-killed animals and factors associated with these accidents were evaluated, such as type of road and traffic density, distance from the built-up area, state of vegetation around the road, terrain topology with regard to the road, and the impact of the month/season.     

Looking Beyond Cargo and Cruise Ships: Promoting Academic Marine Research and Clean Technologies as an Economic Development Strategy for Ports

The Port of Los Angeles (Port) is the largest container port in the Western Hemisphere, and a catalyst for business activity and employment. Historically, the majority of the Port's workforce lived in the communities directly adjacent to the Port. However, in the latter half of the last century, jobs and economic activity began to shift away from the Port, causing public attitudes in the local communities to change. Instead of being viewed as the source of their livelihood, local residents began to view the port as a generator of environmental impacts and industrial blight. Formidable community opposition to Port growth and modernization ensued. Employment within the Port district peaked in the mid 20th century at 100,000. By 2009, the Port had only 12,700 jobs. To re-establish and maintain a long-term positive relationship between the Port and its neighbors, the Port needed to increase the numbers of local residents in the port on a daily basis. The Port looked beyond its traditional role of cargo handling, to leverage creation of new water-dependent job clusters. The strategy incorporates elements of the traditional cluster concept by proposing to co-locate and create synergies between technology developers, university researchers, and marine and maritime industries.     

Decision support for simulating the car park activity in an urban area

Complexity of car park activity is reproduced from a concurrent execution of behaviour of various drivers. This paper presents a step in the development of a multimodal traffic simulator based on multi‐agent paradigm and designed as a decision aid tool as well as a video game. The user‐player has the opportunity to test different scenarios. We propose an approach for designing the decision‐making rules and the learning mechanism for a car driver agent. For that, a panel of methods such as stated preference modelling, Design Of Experiments and data fusion is used. Initial behavioural models, based on similar preferences, are developed for specified categories. Each agent will adapt its behaviour after executing its learning process. Our approach can be used in order to optimize needs of road network users and those of people in charge of traffic regulation. A demonstrator has been developed to test parking policies in an urban area as well as changes of car park characteristics.     

Extant Legal and Jurisdictional Constraints on Irish Coastal Management

The success of any coastal zone management policy is dependent on, among other things, effective legislation and its enforcement. This article examines some possible legal constraints on the implementation of an integrated coastal zone management policy in Ireland. An introduction to the existing legal framework is provided, and the inconsistencies and ambiguities related, in particular, to jurisdiction and area of responsibility are highlighted. In particular the effect of land ownership and property rights on coastal zone management are examined with reference to two popular resort beaches in County Donegal, Ireland. While a revision of the relevant legislation is desirable, it is probably unrealistic; however, powers are available to the various institutions involved in coastal management that are currently unused. These are reviewed and their potential to improve coastal zone management is discussed.     

Persistence of walking in Chile: lessons for urban sustainability

ABSTRACT

An extensive body of work from the urban planning, health, and other disciplines has documented the importance of walking to urban sustainability from health, safety, security, environmental and other perspectives. These studies come mainly from countries in North America and Europe, where the majority of the population relies on cars for transportation. Notwithstanding, in many countries in the Global South, walking remains a majority transport mode, while cars increasingly dominate the urban streetscape, but are accessible only to a minority of the population. Chile provides fertile terrain for studying this phenomenon. This article reviews current practice and recent research of walking in Chile, in light of international findings regarding walkability, equity and urban sustainability. To elaborate an overview of the depth and breadth of walking in Chile, an interdisciplinary team conducted a literature review, examined relevant case study material from experience from Chile and in particular from Santiago, and triangulated this mainly qualitative data with results from the origin-destination survey applied in Chile’s main cities, Chilean traffic safety data) and results from official transport reports of other Latin American cities [Tirachini, A. (2019). South America: The challenge of transition. In J. Stanley & D. Hensher (Eds.), A research agenda for transport policy. Northampton, MA: Edward Elgar Publishing]. Findings show that despite priority public investments that have largely prioritised infrastructure for cars, walking in Chile has remained as the majority transport mode up until today, especially for lower-middle income groups, and particularly for care-related tasks performed mainly by women. In this sense, walking in Chile has proven remarkably persistent. The importance of walking as the main transport mode, against the odds, reflects economic, cultural, and urban form determinants, which are explored in this article. Furthermore, a recent upsurge in public interest and community design initiatives to improve walking, particularly the generation of a Chilean approach to “complete streets” has emerged, opening up opportunities to challenge Chile’s version of automobility in favour of more equitable, active and public transportation modes. There is, therefore, in Chile an opportunity to prioritise the walking mode, improve infrastructure for walkers and build from preserving current high pedestrian modal shares, rather than having to reverse widespread car use, as occurs in many countries in Europe and North America. This potential is highly relevant as these conditions are similar to those in other Latin American cities and, potentially, other cities elsewhere in the Global South.     

Sail-assisted motor vessels weather routing using a fuzzy logic model

In this study sail-assisted motor vessels weather routing is investigated to establish the most economical route by applying available information of the ship's behavior regarding the encountered sea-conditions. To derive the vessel’s fuel use on a route, a fuzzy logic model is constructed through an automated identification process. Only data collected from actual integrated bridge measurements systems is used. Fuzzy modeling is a framework providing a flexible and transparent mathematical structure to describe the physical relationships in a vessel's behavior. This consumption model is integrated into a determinist weather-routing optimization workflow based on a systematic meshing scheme of the sailing area. Pareto-optimization with a multi-objective genetic algorithm is used to maximize fuel economy in a limited or optimum time. The benefits of the developed decision helping tool in sail-assisted motor vessel routing are highlighted on a westbound north Transatlantic journey.
