Abstract
The sustainability of most Mediterranean fisheries is heavily compromised, suggesting the need for an effective policy response to preserve both profitability of fleets and fish stocks in the long run. This study focuses on the Italian small pelagic fleet in the Adriatic Sea. More specifically, we focus on anchovies and sardines' stocks, which account for most of the total catches in the area in terms of landed weight. We build an optimization model aimed at estimating the discounted Maximum Economic Yield (MEY) of this fishery under selected policy scenarios ranging from effort limitations to total allowable catch (TAC) management. The model allows us to compare the bioeconomic performances of the fishery over a time span of 10 years. The results outline a trade-off between biological and economic policy targets, as well as an efficiency gap among fishing gears. This gap ultimately leads to an uneven distribution of economic benefits under restrictive policy scenarios.
期刊介绍:
Ecological Economics is concerned with extending and integrating the understanding of the interfaces and interplay between "nature''s household" (ecosystems) and "humanity''s household" (the economy). Ecological economics is an interdisciplinary field defined by a set of concrete problems or challenges related to governing economic activity in a way that promotes human well-being, sustainability, and justice. The journal thus emphasizes critical work that draws on and integrates elements of ecological science, economics, and the analysis of values, behaviors, cultural practices, institutional structures, and societal dynamics. The journal is transdisciplinary in spirit and methodologically open, drawing on the insights offered by a variety of intellectual traditions, and appealing to a diverse readership.
Specific research areas covered include: valuation of natural resources, sustainable agriculture and development, ecologically integrated technology, integrated ecologic-economic modelling at scales from local to regional to global, implications of thermodynamics for economics and ecology, renewable resource management and conservation, critical assessments of the basic assumptions underlying current economic and ecological paradigms and the implications of alternative assumptions, economic and ecological consequences of genetically engineered organisms, and gene pool inventory and management, alternative principles for valuing natural wealth, integrating natural resources and environmental services into national income and wealth accounts, methods of implementing efficient environmental policies, case studies of economic-ecologic conflict or harmony, etc. New issues in this area are rapidly emerging and will find a ready forum in Ecological Economics.
