Background

The high seas are known to provide a variety of ecosystem services that are of benefit to society. There have however been few attempts to quantify the welfare impacts of changes to the delivery of these benefits. This study assesses the values of several key ecosystem service benefits derived from protecting ecosystems in the high seas area of Flemish Cap. To accomplish this analysis a choice experiment was conducted in three countries: Canada, Norway and Scotland.

Adapting to new climate conditions will require an intricate mix of knowledge, planning, coordination, and foresight. There is increasing sectoral evidence on the implementation of successful adaptation actions. However, the success of these actions when we consider the interdependencies among sectors remains debatable. This paper aims to assess who benefits from implementing adaptation options in a multiuser river basin to both climate-induced and demographic stress on water use.

Abstract

When markets are integrated and the law of one price holds, prices confronted by different producers should tend to uniformity, in the long run, allowance is made for differences in quality and transportation costs. However, how producers coordinate to align prices is not obvious and probably the answer will vary between markets. In this article, we investigate this question using salmon prices differentials, for the main export countries—Canada, Chile, Norway, and the United Kingdom—of farmed Atlantic salmon in the United States market.

We apply the Fishery Performance Indicators (FPIs) methodology to the Southeast Pacific Anchoveta Fishery off southern Peru and northern Chile. Our basic model of analysis is a production function framework, where the performance outcomes are a result of the available inputs. We measured all FPI categories (outcomes and input metrics) and then grouped the metrics into different dimensions suitable for analysis. We obtained the value of each metric from different sources using expert evaluation and secondary information.

Landing price analysis of fish attributes remain undisclosed during the fish harvest landing to landing sites, although it is potential to the wellbeing of artisanal fisher. This study employed a cross-sectional research design and 289 artisanal fishers sampled to investigate fish attributes on landing prices around Lake Victoria, Tanzania, for selected fish species: Nile perch, Tilapia and Sardine species. Two-stage hedonic price model employed in the analysis.
