how subsidies affect the Economic Viability of small scale fisheries
Marine Policy, 2017Co-Authors: Anna Schuhbaue, Ratana Chuenpagdee, William W L Cheung, Krista Gree, Rashid U SumailaAbstract:Abstract This article presents the first bottom-up analysis of the proportion of global marine fisheries subsidies to small-scale fisheries (SSF). Using existing data, the reported national subsidy amounts are split into the fraction that goes to small- and large-scale fishing sectors. Results reveal a major imbalance in subsidy distribution, with SSF receiving only about 16% of the total global fisheries subsidy amount of $35 billion in 2009. To bring this into perspective, a person engaged in large-scale fishing received around 4 times the amount of subsidies received by their SSF counterparts. Furthermore, almost 90% of capacity-enhancing subsidies, which are known to exacerbate overfishing go to large-scale fisheries, thus increasing the unfair competitive advantage that large-scale fisheries already have. The developmental, Economic and social consequences of this inequity are huge and impair the Economic Viability of the already vulnerable small-scale fishing sector. Conclusions indicate that taxpayers' money should be used to support sustainable fishing practices and in turn ocean conservation, and not to foster the degradation of marine ecosystems, often a result of capacity-enhancing subsidies. Reducing capacity-enhancing subsidies will have minimal negative effects on SSF communities since they receive very little of these subsidies to begin with. Instead, it will help correct the existing inequality, enhance SSF Economic Viability, and promote global fisheries sustainability.

Economic Viability and small scale fisheries a review
Ecological Economics, 2016Co-Authors: Anna Schuhbaue, Rashid U SumailaAbstract:Globally, over 90% of all fishing vessels and about 22 million fishers are considered small-scale. Despite their high numbers, small-scale fisheries are often understudied. They are usually Economically and politically marginalized, and therefore vulnerable to large-scale threats (e.g., globalized markets). To support this sector and contribute to its sustainability, we argue that it is fundamental to understand how Economically viable small-scale fisheries are. Hence, the main objective of this article is to critically review and describe the current discourse on the Economic Viability of small-scale fisheries. We find that currently, Economic Viability is mainly equated with financial Viability, where profitability is the goal. In consideration of socio-Economic aspects, the maintenance of nonnegative net benefits to society is often not considered in current notions of Economic Viability. While these shortcomings have been acknowledged in some of the existing literature, our review shows that they have not yet been addressed comprehensively. We therefore conclude that it is necessary to develop or expand current methods to better take into account social aspects when assessing the Economic Viability of small-scale fisheries. This would help find solutions to make these fisheries less vulnerable and better equipped to face large-scale processes of change.

Economic Viability analysis of a construction and demolition waste recycling plant in portugal part ii Economic sensitivity analysis
Journal of Cleaner Production, 2013Co-Authors: Andre Coelho, Jorge De BritoAbstract:Abstract Part I of this paper contained a technological description and Economic evaluation of a large-scale high-end CDW recycling plant in the Lisbon Metropolitan area. It concludes that Economic Viability is likely under the operating conditions considered, but these may and will very probably change in the near future. The reasons for such assumption have to do with the inherent uncertainty related to CDW generation (which might vary, for instance, due to socio-Economic conditions in the region), such as the variability of CDW input gate fees and tariffs associated with landfilling rejected materials, which are market dependent parameters. This made it necessary to perform an (simplified) Economic Viability sensitivity analysis, focused on the investment return period and global Economic balance. If parameters such as the plant's capacity, the CDW input gate fee and landfill fee are varied, the investment return period is affected in different ways, though its value is generally kept below 8 years, for parameter variations of ±30%. The analysis indicates Economic performance for variations in single parameters, except for the plant's capacity, which was considered to vary simultaneously with all others. Extreme best and worst scenarios were also tested in an attempt to define the model's boundaries.

Economic Viability analysis of a construction and demolition waste recycling plant in portugal part i location materials technology and Economic analysis
Journal of Cleaner Production, 2013Co-Authors: Andre Coelho, Jorge De BritoAbstract:Abstract The few construction and demolition waste (CDW) recycling plants that there are in Portugal separate the materials and then crush and sieve them prior to final delivery. These plants have limited overall capacity and the quality of the output material is not good enough for higher grade applications such as concrete and brick production. This study aims to better understand the Economic implications of implementing and operating a large-scale high-end CDW recycling plant to serve a densely populated urban area in Portugal (Lisbon and its outskirts). This first part deals with the location of the plant, its design and the material entering and leaving it. There follows an Economic analysis which leads to the sensitivity analysis presented in part two, which provides important conclusions for the Economic Viability of full-scale CDW recycling plants. The methodology used can be applied to other locations and resulted, within the regional data frame of the Lisbon Metropolitan area, on a return of the investment period of around 2 years, considering a plant capacity of 350 tonne/h, the collection of 21.8 million €/year in gate fees and the need to pay around €11.9 million €/year in running costs. Hence, there is a high profit potential in this venture, even though considering the high initial investment needs. Moreover, the venture seems Economically viable even in the absence of specific regulatory government policy intervention for recycling CDW, which may indicate a clear alignment between Economic Viability and environmental benefits, arising from this CDW recycling plant operation.

the Economic Viability of commercial wind plants in greece a complete sensitivity analysis
Energy Policy, 2000Co-Authors: J K Kaldellis, Th J GavrasAbstract:Abstract The influence of the governing techno-Economic parameters on the Economic behaviour of commercial wind parks is investigated. For this purpose, a complete cost–benefit analysis model, properly adapted for the Greek market, is developed in order to calculate the pay-back period and the Economic efficiency of similar investments in the energy production sector. Moreover, the impact of various parameters — such as capital cost, return on investment index, local inflation rate index, electricity price escalation rate, installation capacity factor, M&O cost, turn-on key cost of the power plant, size of wind turbines used — on the Economic Viability and attractiveness is extensively investigated, using a well-elaborated simple “expert system” type numerical code. Finally, the prediction results are summarised in a representative sensitivity analysis map, including the most reasonable Economic scenarios. Taking into account the analytical results of the proposed study along with the existence of high wind potential regions in Greece, a remarkable growth of the wind energy sector is expected in the near future, leading to considerable investment profits and offering a strong position (share) of the liberalised local power market.
