Marine habitats and the fisheries they support may be modified through the use of human-made physical structures placed in the sea. These structures ('artificial reefs') serve a variety of functions, ranging from the traditional practice of food production to newer applications which include mariculture, tourism and resource conservation. The presentation...
Aquaculture worldwide has grown rapidly, and while this has brought socio-economic benefits to particular regions there is persistent concern over its environmental impact and sustainability. Within Europe there are quite marked regional variations in the intensity of marine aquaculture, and the fact that this occurs in areas where there is...
Economic performance of different fleet segments varies considerably from year to year, with some segments experiencing increased profitability while others experience decreased profitability. This variation is generally considered to be a consequence of the stochasticity in the industry. However, there is growing evidence that fisheries may not be as stochastic...
Fisheries exploited under open-access conditions create externalities, resulting in a range of problems associated with over-capitalisation and stock depletion. One answer to this is to shift the mode of production away from hunting and towards husbandry, an approach which becomes feasible where some control can be exercised over the resource...
In southeast Portugal, some coastal fishing communities have experienced intensified competition for harvestable stocks, and this impacted with some severity on small-scale fishermen who are especially dependent on fishing for their livelihoods. In the last decade or so, various "structural instruments" have been created in order to address this particular...
It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...
There has been a growing interest in recent years in the potential use of product differentiation (through eco-type labelling) as a means of promoting and rewarding the sustainable management and exploitation of fish stocks. This interest is marked by the growing literature on the topic, exploring both the concept and...
Despite growing interest in Marine Protected Areas, relatively little is still known in practice about their economic impact or their distributional consequences for stakeholders. The present paper, based on an EU-funded project, attempts to shed light on this issue by examining the economics of an artisanal fishery operating in an...
This paper aims to reveal consumers’ preferences for quality graded fish products based upon existing data on first-hand sales in Denmark. The data represents the value of fish for consumption as a non-differentiated private good.
The objective is to measure the welfare gains to society of an increase in “quality”...
The last decade has seen a drastic interest in microgrids throughout the world. Even though this trend might seem to be just another technological solution in the energy sector, it is a part of a greater transition from a centralized energy system to a more decentralized one. However, unlike most...
Nuclear energy enjoyed widespread support in the United States during its initial decades and has seen extensive study as a potential means of combating contemporary energy issues such as climate change and alternative transportation fuels. Despite the potential contribution to solving these challenges, the industry has been largely stagnant since...
Transitioning from fossil fuels to renewable energy sources has been identified by governments throughout the world as a key strategy for reducing air pollution and greenhouse gas emissions, enhancing sustainability and resiliency, and supporting local economies. Despite these benefits, this transition has been slow in the United States, causing some...
Co-management is considered an alternative approach to fisheries management,
however, not all co-managed fisheries have been successful. Most studies discussing the
success and failure of co-management have emphasized economic and social attributes of
success and failure, such as fishery rights and institutional arrangements. The effect on
co-management of biological characteristics,...
Natural disasters are an increasingly costly and frequent occurrence globally and in the United States (IPCC, 2012; IPCC, 2014; Berlemann & Steinhardt, 2017). Discrete disaster events, such as coastal flooding, have been shown to be push factors in temporary and long-term migration (Black et al., 2013). Policy efforts to adapt...
Photobiological hydrogen production from live cells of the cyanobacterium Synechocystis sp. PCC 6803 encapsulated in silica gel was investigated. Hydrogen is a dense energy carrier with potential to reduce dependence on fossil fuels, provided a renewable and sustainable means of production can be achieved. Under certain conditions, Synechocystis sp. PCC...
Numerous flights of Quaternary marine terraces are present around the island of Cyprus, in the Eastern Mediterranean. These terraces are a result of the global eustatic sea-level curve and local tectonism. Marine Isotope Stage (MIS) 5 through MIS 13 terraces are identified, mapped and dated. Palaeoshoreline elevation, an excellent indicator...
The concept of natural resource rents is much used in the natural resource and fisheries
economics literature. It is therefore somewhat surprising that in this same literature it is difficult
to find a clear definition of either natural resource rents or fisheries rents. Possibly, as a result,
the concept is...
Seafood ecolabel, such as Marine Stewardship Council (MSC) label continues to expand worldwide,
particularly in European and US markets. Consumers’ response to ecolabeled seafood products in these
markets has been studied in the past, mostly with encouraging results. Meanwhile, and after a decade
since the establishment of MSC, seafood ecolabel...
As the various mechanisms of fisheries resources management have matured, fishermen increasingly have responded by devising and developing different forms of collective representation. Within the European Union (EU), Producer's organisation (POs) provide a voluntary organisational structure which has evolved since its inception in the 1970s. During the intervening period, POs...
The Conference Program for IIFET, held July 10-14 in Corvallis, Oregon. Program lists the sessions by date and time and includes the session titles, speakers and paper titles.
Most trade literature is concerned with gains from free trade under the assumption that traded goods are produced under complete property rights. Seldom have researchers examined the consequences of free trade in the presence of incomplete property rights over renewable natural resources. In this paper, we explore these consequences. In...
A logical analysis of the common fisheries models used in stock assessment has shown that they produce specific predictions with the logical form of existential statements, fail Karl Popper’s falsifiability criterion, and so cannot be falsified or tested by the empirical evidence. By contrast, the theoretical models of fisheries economics...

It is possible to purchase, for as little as $10,000, a cluster of computers with the capability to rival the supercomputers of only a few years ago. Now, users that have little to no experience developing distributed applications or managing a cluster are in a position to do so. To...
The environmental movement needs people from communities of color and the differing perspectives they provide. Latinas/os are one of the largest communities of color in the US, and their numbers continue to grow. However, mainstream environmental organizations have failed to engage this community in authentic ways. The lack of meaningful...
This thesis reviews theoretical and local understandings of sustainability and examines the contributions which the NGO, the Toledo Institute for Development and Environment (TIDE), makes to achieving sustainability in the district of Toledo in Belize, Central America. The study focuses mainly on the Port Honduras Marine Reserve, which TIDE manages...
Decision-making is a highly complex process influenced by the values, attitudes, and cognitive biases of the decision-maker. The classical model of decision-making fails to fully incorporate how decisions are made in situations of uncertainty, where having complete knowledge of all possible outcomes and alternatives is not always possible. In highly...
