Assessing the significance of the economic impact of Marine Conservation Zones in the Irish Sea upon the fisheries sector and regional economy in Northern Ireland

This paper highlights the tension between advocacy for ‘Blue growth’ in maritime policy and efforts to safeguard future economic growth via the Marine Strategy Framework Directive. In 2015, policy-makers withdrew three of four proposed Marine Conservation Zones (MCZs) in the Irish Sea from consideration for designation, due to concerns that they could significantly impact on the fisheries sector in Northern Ireland because they overlap with prawn fishing grounds in the Irish Sea. Although research has quantified the potential impact upon fishing vessels, none has quantified the impact upon the fisheries sector nor assessed the significance of this impact. Arguably, MCZ designations (or lack thereof) based on the ‘significance’ of an impact require robust underpinning evidence. This paper reports the findings of an Economic Impact Assessment, which has quantified the impact of a decline in landings upon the Northern Ireland fisheries sector and regional economy (data which is currently absent from the evidence base for the MCZ designation process in England). It finds that this will incur job losses in three fishing ports in Northern Ireland, but is unlikely to have a significant impact upon Northern Ireland's fisheries sector and regional economy in terms of jobs and Gross Value Added (GVA). In the worst case, the resulting economic impact is a decrease of £1.05–1.12 m/year GVA in Northern Ireland, which is 1.1% of the contribution of fishing and fish processing to the regional economy. Economic significance assessments, using this methodology, may be useful in supporting the evidence base underpinning MCZ designation and other aspects of marine planning.     

The role of the marine sector in the Irish national economy: An input–output analysis

Recent research in Ireland has estimated both the national and regional economic value of the marine sector. However, economic activity does not exist in a vacuum. Activities in the marine sector not only directly affect the industries in the sector but also influence other sectors through inter-sectoral linkages. This paper uses an input–output (IO) methodology to examine the linkages and production effects of the Irish marine sector on the national economy. Disaggregating the Irish IO table for 2007 to include 10 additional marine sectors, this paper represents the first effort to quantify the inter-industry linkage effects, production-inducing effects and employment multipliers in the marine sector. This analysis found that a number of marine sectors, notably the maritime transportation sector, have an important economic role within the wider Irish economy.     

The Irish marine economy and regional development

The economic impact of the marine economy is poorly understood at both national and regional levels in Ireland. A recent paper estimated the national level economic value of the sector for Ireland. This paper presents a follow up analysis of the Irish marine sector at the regional level for 2007. The paper examines the impact of the marine sector in addressing regional disparities in Ireland, and the key marine sectors that drive regional economic performance within the marine sector. The analysis finds that in absolute values Dublin and the South West provide the highest levels of marine GVA; however, as a percentage of regional GVA, the marine sector is more important in the West and South West region. In terms of employment, the West and South-West provide the highest levels of marine employment, and this relationship is maintained when one examines marine employment as a percentage of regional employment. Finally, productivity rates for the sector were highest in the Dublin region. However, productivity in the marine-based sector was higher than the overall regional rate for five of the eight Irish regions.     

Identifying channels of economic impacts: An inter-regional structural path analysis for Alaska fisheries

Alaska fisheries have strong spillover effects on economies of other states (especially the state of Washington) due to their dependence on imports from these other states. Several studies attempt to develop inter-regional or multi-regional economic impact models to investigate these spillover effects, and calculate the multipliers for Alaska fisheries. However, these multipliers measure only total economic impacts, failing to provide fishery managers with the information on how and along what channels these total economic impacts are generated and transmitted throughout the regions. This paper uses an inter-regional structural path analysis (IRSPA) to identify the various channels (paths) through which the economic impacts of an initial shock to a seafood sector are transmitted, amplified, and spilled over to other regions, within an inter-regional social accounting matrix (IRSAM) framework for two US regions – Alaska and the rest of US (RUS).     

Valuing seafood: The Peruvian fisheries sector

There are tradeoffs in managing fisheries, and ideally such tradeoffs should be known when setting fisheries policies. An aspect of this, which is rarely considered, is the spin-off effect of different fisheries: the economic and social benefits that fisheries generate through processing through distribution and on to the end consumer. This study evaluated the benefits generated in the Peruvian marine fisheries sector through a comprehensive value chain analysis, based on a newly-developed combined ecosystem-economic modeling approach, which was integrated in the widely-used Ecopath with Ecosim approach and software. The value chain was parameterized by extensive data collection through 35 enterprise types covering the marine fisheries sector in Peru, including the world's biggest single-species fishery for anchoveta. While anchoveta is what is known about Peruvian fisheries, the study finds that anchoveta accounts for only 31% of the sector contribution to GDP and for only 23% of the employment. Thus, while anchoveta indeed is the fundamental fish species in the Peruvian ecosystem, there are other fisheries to be considered for management. The study indicates that the economic multipliers for Peruvian fisheries were 2.9 on average over the industry, and that these varied surprisingly little between fleets and between seafood categories indicating that the multipliers can be used beyond Peru to generalize the spin-off effect of the value chain. Employment multipliers vary much more across types of fisheries, but also around an average of 2.9; here it was clear that longer value chains result in more employment.     

The discard ban policy,economic trends and opportunities for the Portuguese fisheries sector

In this paper the discard ban policy within the Portuguese fisheries sector is discussed and the opportunities and impact in the fisheries economy that arise from sales of unwanted fish under the new landing obligation are evaluated. The decadal mean price of fish (€/kg, adjusted for inflation) rose from the 1940s until the 1970s, dropping thereafter. The yearly averaged economic income estimated for discards sales between 1969 and 2009 ranged from 419345€ to 2164379€. Discard ban sales could contribute from 10% to 53% of the total landed value and 9–34% of the total catches (landings + discards). Under a discard ban policy, the fishing sector with the largest economic contribution for total discards sales would be multispecies (54%), followed by trawl (26%) and seine (20%). On average, fishing sales contributed with 0.63% to gross domestic production (GDP) between 1938 and 2009. Discard sales can increase 1.07–1.46 times more than the fish landing contribution to GDP. After 1983 the average landings/imports economic ratio was 0.28:1, which means that fish imports surpassed landings economic value 3.57 fold. The discard ban policy can create economic opportunities in the national context thus helping to revitalize some specific fisheries sectors.     

The role of the capture fisheries and aquaculture sectors in the Korean national economy: An input–output analysis

The aquaculture industry can meet food security needs and reduce the pressure on marine resources. The expansion of aquaculture allows the fisheries industry to restructure from hunting to farming, and thus drives the need for an analysis of the economic impacts of aquaculture industry in consideration of the interdependence between capture fisheries and aquaculture industry. This study attempts to analyze the economic impacts of two fishery sectors using input–output (I–O) analysis, with specific application to Korea. To this end, this study applies the I–O models to the Korean I–O tables generated by the Bank of Korea, paying particular attention to the two fishery sectors in Korea, considering them as exogenous, and then determining their impacts. Specifically, the production-inducing effects, employment-inducing effects, supply shortage effects, sectoral price effects, forward linkage effects, and backward linkage effects of the two fishery sectors are presented over the period 1995–2010. For example, the production-inducing effect of a KRW 1.0 change in fisheries investment is larger in the petroleum and chemical sectors than in other sectors. Moreover, the aquaculture sector has larger employment-inducing effects than the capture fisheries. Finally, the potential uses of the results of this analysis are presented from the perspective of policy instruments, and policy implications are discussed.     

From krill to convenience stores: Forecasting the economic and ecological effects of fisheries management on the US West Coast

There is a need to better understand the linkages between marine ecosystems and the human communities and economies that depend on these systems. Here those linkages are drawn for the California Current on the US West Coast, by combining a fishery ecosystem model (Atlantis) with an economic model (IO-PAC) that traces how changes in seafood landings impact the broader economy. The potential effects of broad fisheries management options are explored, including status quo management, switching effort from trawl to other gears, and spatial management scenarios. Relative to Status Quo, the other scenarios here involved short-term ex-vessel revenue losses, primarily to the bottom trawl fleet. Other fleets, particularly the fixed gear fleet that uses pots and demersal longlines, gained revenue in some scenarios, though spatial closures of Rockfish Conservation Areas reduced revenue to fixed gear fleets. Processor and wholesaler revenue tracked trends in the bottom trawl fleet, which accounted for 58% of total landings by value. Income impacts (employee compensation and earnings of business owners) on the broader economy mirrored the revenue trends. The long-term forecast (15 years) from the Atlantis ecosystem model predicted substantial stock rebuilding and increases in fleet catch. The 15 year projection of Status Quo suggested an additional ∼$27 million in revenue for the fisheries sectors, and an additional $23 million in income and 385 jobs in the broader economy, roughly a 25% increase. Linking the ecological and economic models here has allowed evaluation of fishery management policies using multiple criteria, and comparison of potential economic and conservation trade-offs that stem from management actions.     

Estimation of fisheries removals and primary economic impact of the small-scale and industrial marine fisheries in Colombia

Colombia has coasts on both the Atlantic and Pacific Oceans, but its marine fisheries are limited by the relatively small size of commercially important stocks. However, diverse fishery resources have traditionally been exploited by coastal communities, and industrial fisheries have grown in recent years with the intensification of tuna fishing in both oceans. The management of Colombia's fisheries has been hampered by frequent administrative changes, which has notably led to the disappearance of a part of the official landings data. We estimated total fisheries removals (reported plus discards and unreported catches) in the Colombian Atlantic and Pacific Oceans for the period 1950–2006. We used secondary sources of information to estimate missing data, and we estimated subsistence fishing and the unreported by-catches of the shrimp and tuna fisheries. We used available information on seafood prices to estimate the relative economic impact (gross revenues) of the small-scale and industrial sectors for the period 2000–2006. Our results suggest that for the period 1950–2006, the Colombian marine fisheries catches may have been almost twice the landings reported by FAO on behalf of the country (2.8 times higher in the Atlantic; 1.3 times higher in the Pacific). Although the total gross revenues of industrial fisheries were higher than those of the small-scale sector, the latter commanded higher gross revenues in the Atlantic in 2006.     

The economic importance of the Icelandic fisheries cluster—Understanding the role of fisheries in a small economy

Expansion and development of the fisheries sector was the driving force behind Iceland’s economic transformation during the 20th century. However, the role of fisheries in national and regional economies is neither well documented nor understood. National accounts do not fully reflect the significant part played by the fisheries as they do not take into consideration the various ways economic activity in the fisheries sector affects other branches of the economy. The fisheries sector, which includes fishing and fish processing, has been established as a base industry within the Icelandic economy. Using data collected during 2010 and 2011 and cluster analysis techniques, this paper seeks to establish the economic importance of the fishing industry in Iceland. As a base industry, this paper finds that a wide range of companies have gradually developed to service the sector and through these interlinkages, the fisheries sector and its related operations can be viewed as an industry cluster.     

The use of a consequential perspective to upgrade the utility of Life Cycle Assessment for fishery managers and policy makers

Attributional LCA, which monitors specific production systems in steady state conditions, is increasingly used in fisheries to assess the environmental profile of fleets and seafood supply chains. However, this approach is not pertinent to assess the environmental consequences of (large scale) policies. In contrast, consequential LCA (CLCA) has been successfully implemented in other sectors to assess the expected changes in environmental impacts of a given production system and other (marginal) production systems that may be affected in response to changes driven by policy or strategic decisions. CLCA commonly combines LCA with economic models to simulate the interactions occurring between the analysed systems. However, the use of these models may not be the most appropriate approach to follow for fisheries. Hence, it seems feasible that CLCA should be combined with stock prediction tools rather than with economic models, to determine how changes in stock sizes and quota restrictions may cause variations in the environmental impact of fishing fleets.     

Fisheries traffic: The poor relation of port devolution. Lessons from Spanish state ports of general interest

The fisheries sector is currently contending with the hectic development of its own political economy framework being convulsed by the dynamics of decentralisation. This process is enshrouded in an environment of economic globalisation, taking place against the backdrop of the governance approach. With this situation as the starting point, the main goal of this paper is to quantify the effects that the Spanish port devolution process might have on the Spanish fisheries sector through the use of a transfer function model; the volumes of landings at State ports of general interest and their cash value are taken as dependent variables.     

Fisheries development in Vietnam: A case study in the exclusive economic zone

Pursuant to statement issued by the Government of Vietnam on 12 May 1977, on the territorial sea, the contiguous zone, the exclusive economic zone (EEZ) and the continental shelf of Vietnam, and according to the provisions of the LOS Convention, the EEZ of Vietnam extends principally up to 200 NM from the baseline, and the area of EEZ amounts to about one million square km including the Hoang Sa (Paracel) and Truong Sa (Spratly) Islands [The declaration of the Government of Vietnam on the territorial sea, contiguous zone, exclusive economic zone and continental shelf, Hanoi, 1977]. The establishment of EEZ has significantly changed circumstances for the fisheries sector in Vietnam.Recently, even though the adaptation of new techniques and technologies to the fisheries sector has been somewhat successful and resulted in the limitation of effective exploitation opportunities, sea fishing is still very important to the economy of Vietnam. In fact, fisheries development in Vietnam has the following important objectives, whether pursued in marine or fresh water: foreign exchange earnings; protein for local diets and feeds for live stock; provision of employment. However, a matter of concern is that the outdate fishing methods and uncontrolled fishing are damaging the marine environment and living resources. These problems have been recognized and courses of action have been formulated. A prerequisite condition for resolving this issue is to have a mechanism for synchronized policies which are guaranteed by appropriate macro management. The main purposes of this paper are a review of some aspects of fisheries sector development and management in Vietnam in the light of the new regime of the EEZ, represented in the LOS Convention. An important objective of the paper is the emphasis on the problem of policy-relevant research for fisheries sector management in the future.     

Editorial: Reflections from Ireland

Responses of governance systems to change in coastal and marine ecosystems vary from country to country around the globe. Lessons can be learned from country specific case studies, as national governments strive to adapt and respond to issues of concern. This short paper highlights the benefits of a country-specific, special edition of Marine Policy, with a focus on Ireland. Despite the uniqueness of socio-ecological setting, many of the issues faced by policy makers in Ireland, such as the reconciliation of economic development and conservation needs, are shared elsewhere. This special edition was produced at the end of the ‘Celtic Tiger’ in Ireland. As a result, it reflects an era when economic development was very much a priority. The same period represented an unparalleled investment in marine science since the foundation of the State in 1922. Despite this, the papers in the Special Edition point to varying degrees of progress in policy integration and implementation. Papers covering a range of sectors (fisheries, ocean energy, conservation and fisheries) and disciplines (economics, science and management) will be of interest to academics, policy makers, students and practitioners of marine policy.     

Fisheries biodiversity conservation and sustainable tourism in Mauritius

This paper addresses the sustainability of the tourism sector from the perspective of a Small Island Developing State (SIDS), Mauritius. In this respect, the relationship between tourist earnings and fisheries biodiversity is examined. We begin, in the first place, by tracking and analyzing the evolution of fisheries biodiversity, a catalyst of the island's tourism, through the computation of Shannon's entropy index applied to 20 categories of fish experimented over a period of 25 years. In the second stage, this index is introduced, along with other control variables, in a regression equation to ascertain its potential impact on the value added of the tourism sector. Our empirical findings based on 25 years of observations undeniably reveal that fisheries biodiversity does play a major role in enhancing the revenue generated by the tourism sector. Hence, it is vital to promote biodiversity conservation, at least within the fisheries sector, to sustain economic progress; more so, given that tourism constitutes a major pillar of the economy of Mauritius and which is expected to grow even further.     

The transition from the Soviet system to a market economy as a cause of instability in the Estonian coastal fisheries sector

This study analyzes how overall changes in political and economic life during the last decade have affected the Estonian coastal fishery of the Baltic Sea. At the beginning of the nineties, the opportunity to export fish to the European market emerged. Opening of this new market resulted in rapidly increasing pressure on fish stocks. Some of the most important coastal fishery resources were over-fished because of high export market demand coupled with insufficient resource management and ineffective control and enforcement mechanisms. The costs associated with fishery have grown much more than the first-buyer prices. Additionally, dynamic development of the Estonian economy has resulted in substantial increases in earnings in other economic sectors and therefore the relative wealth of fishermen has steadily declined. This has resulted in increasing social problems. In conclusion, countries in transition may encounter serious difficulties in the fisheries sector, arising from privatization and economic reforms, which may affect the fisheries even years after the establishment of new ruling principles.     

How much are the Bolinao-Anda coral reefs worth?

The Total Economic Value of the estimated 200 km² of coral reef area straddling the municipalities of Alaminos, Anda, Bani and Bolinao in Pangasinan, Philippines is estimated to reach US$38 million per year consisting mainly of indirect benefits from shoreline protection. Direct use from fisheries, aquaculture, and tourism was valued at US$6 million based on the coral reef interaction index. Non-use values for coral reef conservation were based on estimates of willingness to pay across the three economic sectors plus the general public as a fourth sector. Results varied across sectors and municipalities although the ranges were not wide, especially for fishers. Fishers’ willingness to pay averaged at US$0.25 per individual per year. Except for aquaculture operators in Bolinao, which yielded willingness to pay values reaching US$3 per individual per year, the range of conservation funding was narrow for the three other municipalities for all sectors. Using binary logistic regression (logit model), differences in willingness to pay among fishers are explained by the age, number of children, and employment status.     

New Zealand seafood firm competitiveness in export markets: The role of the quota management system and aquaculture legislation

New Zealand's quota management system (QMS) was implemented in 1986 to address problems caused by a regulated open entry management system in place for the previous two decades. Excess capacity in the inshore fisheries caused several stocks to become depleted and conflicts to intensify between fishing sectors. The allocation of individual transferable quota (ITQ) was viewed as the best way to improve efficiency within the over-capitalised inshore fisheries and provide incentives for developing the deepwater fisheries. The expected benefits of the QMS fit with the political climate at that time, as the government was using market forces to address the deteriorating economy. This article outlines the results of a research project that involved four medium to large-sized, highly vertically integrated New Zealand seafood firms. The purpose of the project was to identify these firms’ sources of competitiveness in export markets and the process the firms used to develop sources of competitiveness, while adapting to rapid and radical changes to the political and business environment and transformation of the fisheries management system. The project's results show that the basis to seafood firm competitiveness is the security of supply to the fisheries resource provided by the QMS and aquaculture legislation. The project also outlines the role that government policies have in sustaining firm- and industry-level competitiveness. This article contributes to the broader discussion on the application of ITQ and other types of long-term access rights to the management of fisheries and does not express the views of the Ministry of Fisheries.     

Assessing catch shares' effects evidence from Federal United States and associated British Columbian fisheries

What are the effects of transitioning traditionally managed fisheries to incentive-based catch shares fisheries? In a study of all major United States federal catch share fisheries and associated shared stock fisheries in British Columbia, catch shares result in environmental improvements, economic improvements, and a mixture of changes in social performance, relative to the race for fish under traditional management. Environmentally, compliance with total allowable catch increases and discards decrease. Economically, vessel yields rise, total revenues grow, and long-term stock increases are encouraged. Socially, safety increases, some port areas modestly consolidate, needed processing capacity often reduces, and labor markets shift from part time jobs to full time jobs with similar total employment. Newer catch shares address many social concerns through careful design.
