With many countries seeking to increase the area conserved in marine protected areas (MPAs) to achieve the Convention on Biodiversity’s protected area targets by 2020, we employ a bioeconomic model to determine which configurations of MPAs that meet area targets perform the best for secondary goals, including fishing yield, rural income, fish stocks, and sea turtle conservation.

Bait tuna boats in developing coastal countries compete for small pelagic stocks such as anchovy that are primarily targeted by artisanal fishers. The tuna vessels are typically foreign owned, their catches are exported, and the vessels pay taxes to the resource-rich countries; by contrast, the artisanal fishers exploit the small pelagic stocks to support their livelihoods. In addition, the technologies employed in catching the baitfish (i.e., intermediate input) may destroy the benthic floor of the management area of artisanal stocks.
This study compares the performance of the industrial deep-sea shrimp fishery in the Colombian Pacific prior to and following important management reforms aligned with the FAO Code of Conduct for Responsible Fisheries. The Fishery Performance Indicators (FPIs) methodology was applied to examine changes in the ecological, economic and social outcomes brought about by the reforms. The analysis revealed that regulatory reform improved environmental performance through increases in stock size and
The rebuilding of collapsed fisheries is a major challenge for fisheries science and management, requiring multi-faceted evaluations to assess the current and potential performance of recovering fisheries. Single-dimensional analyses such as stock abundance assessments are only partially effective in determining the best course of action for fisheries in this condition.
As in other ecosystems, provision of ecosystem services from forests is uncertain because of stochastic weather conditions. In general, society is risk-averse, which means that factors increasing or decreasing the uncertainty in ecosystem services add a source of cost or value to society, measurement of which is lacking in the literature. This article suggests a method for calculating the impact of site-specific ecological conditions in Swedish forests on the economic value of uncertain ecosystem services in terms of timber and carbon sequestration.
Assessing social acceptability and welfare effects of policy instruments to reduce marine plastic pollution: a multi country choice experiment
The objective of this study, which is starting in 2020, is to contribute to the design of policies to reduce marine plastic pollution, by assessing the preferences of households and the welfare
