Economic appraisal of the impacts of fisheries policies is a legal requirement in many global fisheries and is crucial for effective policy making. Some changes in costs and benefits attributable to policy can be assessed through impacts on markets, whilst others are more difficult, as markets may not exist. Analysis is needed to assess value gener...

While the science supporting fisheries management has generally been dominated by the natural sciences, there has been a growing recognition that managing fisheries essentially means managing economic systems. Indeed, over the past seven decades, economic ideas and insights have increasingly come to play a role in fisheries management and policy. A...

Fishery management relies on forecasts of fish abundance over time and space, on scales of months and kilometres. While much research has focussed on the drivers of fish populations, there has been less investigation of the decisions made day-to-day by fishers and their subsequent impact on fishing pressure. Studies that focus on the fisher decisio...

The designation of large scale marine protected areas (MPAs) has increased in recent years to address global issues such as biodiversity loss and the conservation of vulnerable marine habitats. While designing a large scale MPAs in the Exclusive Economic Zone (EEZ) of Ascension Island, the monitoring and enforcement costs were estimated for the two...

Despite their prevalence in European and Atlantic waters, knowledge of best-practice methods of data collection in SSF is currently lacking. This has led to the collection of data that is often incomplete or of poor quality, and that underplays the fisheries’ wider importance. Furthermore, the diversity of gear, target species, seasonality, and geo...

Long-term trends in seafood production and demand indicate a need to move away from capture fisheries in favour of increased aquaculture production. The paper explores the potential social and economic barriers towards creating a more holistic seafood production chain. Fisheries not only provide food but also play a significant role in the provisio...

Recreational sea angling is a popular activity generating significant socio-economic benefits but can impact on fish stocks. The motivations of recreational sea anglers go beyond catch, with a diverse range of motivations relating to physical health and well-being. Heterogenous motives and the popularity of catch and release practices mean that app...

The importance of social and economic factors, in addition to biological factors, in fisheries management is being increasingly recognised. However, exploration of trade-offs between biological, social, and economic factors under different sustainable catch limits for recreational and commercial fisheries is limited, especially in Europe. The Europ...

The potential for the UK inshore fleet to either switch from wild capture fisheries to aquaculture or integrate it within its business model as a livelihood option was investigated. The aim was to assess the opportunities, barriers and potential for developing a more holistic seafood production system and to generate information for future policies...

The paper argues that the level of public spending on health varies according to the type of political regime in a country. A simple political economic model is employed to analyse the rationale of policy makers when implementing healthcare policy. The theory of dictatorship as described by Wintrobe (1990, 1998, 2001) is used to differentiate betwe...

The ICES Working Group on Mixed Fisheries Advice (WGMIXFISH-ADVICE) chaired by Claire Moore, Ireland, met at ICES headquarters in Copenhagen, Denmark, 28 October–1 November 2019 to produce mixed fisheries forecasts for the North Sea, Celtic Sea, and Iberian waters. Mixed fisheries advice highlights the potential implications of single-stock (total...

Many jurisdictions have a legal requirement to manage fish stocks to maximum sustainable yield (MSY). Generally, MSY is calculated on a single-species basis, however in reality, the yield of one species depends, not only on its own fishing level, but that of other species. We show that bold assumptions about the effect of interacting species on MSY...

The overarching focus of Working Group on Maritime Systems (WGMARS) has been on under-standing the conceptualisation and implementation of Integrated Ecosystem Assessments (IEAs) in ICES and more broadly. From 2017-2019, the Working Group reviewed academic literature and ICES documents, interviewed the chairs of the ICES Regional Seas Working Group...

Defining fishing grounds based on data from Vessel Monitoring System (VMS) has been a widely-researched topic in recent years. Much of the research has focused on filtering algorithms for identifying fishing locations from VMS point data, most often supplemented with either imputed or reported vessel speed inform ation. This study compared the prec...

Information acquired by fishermen while fishing play a crucial role in their decision-making process. Those are used to form the basis for update of beliefs on productivity of a range of available fishing grounds while acting in an uncertain environment. In this paper, we focus on the formation of fishermen's beliefs about the productivity of fishi...

European competition authorities consider environmental and competition policy to be complementary, as each has the objective of improving social welfare. Naturally, one would imagine that environmental considerations have already been accounted for in competition policy practice, but thus far, only in the case of voluntary environmental agreements...

European competition authorities see environmental policy and competition policy as compatible since both has the objective of improving social welfare. Naturally one would think that environmental considerations have already had a place in European competition policy, but so far this has not been the case. Based on the existing EU practice the rel...

This paper takes a closer look on the infection rates of epidemic diseases in developing country, in particular HIV/AIDS and tuberculosis. The question which arises is why large differences in prevalence rates can be observed in countries with comparable economic performance. A short panel analysis is conducted for 104 low-and middle income states...

In this paper part of the existing Agri-Environmental Schemes (AES) of the European Union are evaluated by using data on county level instead of applying field studies. The attempt is made to disentangle the effects of AES on land management practice as well as land use on biodiversity. It is argued that subsidies as AES should promote environmenta...

This paper explores possible interdependence of biodiversity and several socioeconomic and political factors at the county level. It is aimed at the empirical identification of direct and indirect effects between biodiversity (loss) and their theoretical major impact factors. To date, research shows that in addition to geography, agriculture is one...

This paper analysis the possible demand for nature conservation within the Bavarian population. Drawing on the approach of revealed preferences and the mechanism of 'vote with their feet' of Tiebout (1956) migration patterns in Bavarian counties are examined in more detail in order to assess the role of biodiversity for migration decision according...

This paper seeks to explore possible interdependence of different biodiversity indicators with socio-economic and political factors on a county and regional level. As example the counties in Thuringia and Bavaria (Germany) are chosen in order to conduct ordinary-least square estimations as well as structural equations in order to identify possible...

We jointly analyze the genesis of terrorism and civil war, providing a simple conceptual framework to explain why violent opposition groups choose distinct forms of violence (i.e., terrorism and open rebellion). We argue that the distinct modes of violent opposition are chosen by violent opposition groups in response to the strengths and weaknesses...
