On June 11th, in the context of the webinar program La hora acuícola (Aquaculture time), EfD researchers, Carlos Chávez and César Salazar, and coauthor Jeanne Simon, presented a study on the effects…
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.
The extensive kelp forests along Chile’s coastline are an important source of income for many small fishing operations in Chile. But harvesting pressure has denuded many areas of the sea floor, threatening the health of the inshore marine environment. Recently, small operators have begun work to repopulate and/or cultivate seaweed. This work aims at studying the role of fishing and agriculture as outside options and their interactions with risk and time preferences in the uptake of seaweed aquaculture technology.
The capture fisheries sector is a critical source of animal protein in Africa. In addition, the sector creates jobs, and contributes significantly to agricultural GDP and non-traditional export
Share contracts are the dominant remuneration system in artisanal fisheries. Introducing regulations based on collective use rights may affect the way profits are distributed. The literature on the effect of regulatory reform on factor income distribution, however, is scarce. In this paper, we look at differences in the implementation of the Extractive Artisanal Regime in Chilean hake artisanal fisheries to test its effect on share contracts. We estimated a switching regression model using census data to calculate the average treatment effect.
