Saving the Seas: The Economic Justification for Marine Reserves
نویسنده
چکیده
We contribute to the understanding of marine reserves and the management of renewable resources with uncertainty. We show that the key benefit of reserves is that they increase resilience, or the speed it takes a population to return to a former state following a negative shock. Resilience can also increase resource rents even with optimal harvesting. We contradict the accepted wisdom that reserves have no value if harvesting is optimal, reserves and optimal output controls are equivalent, reserves have value only with overexploited populations and that reserves must be large to offer benefits to fishers.

High-seas fish wars generate marine reserves.
The effective management of marine fisheries is an ongoing challenge at the intersection of biology, economics, and policy. One way in which fish stocks-and their habitats-can be protected is through the establishment of marine reserves, areas that are closed to fishing. Although the potential economic benefits of such reserves have been shown for single-owner fisheries, their implementation qu...
متن کاملRationale for a System of International Reserves for the Open Ocean
" The sea! the sea! the open sea! The blue, the fresh, the ever free! " —Bryan W. Procter, ca. 1837 There appears to have been little consideration given to the concept of marine reserves in open-ocean ecosystems , whereas a large number of protected areas for coastal marine and estuarine ecosystems have been or are now being developed around the world (Agardy 1994; Rowley 1994). We argue that,...
متن کاملOptimal Detection of Oil Contamination at Sea by the FPSO Algorithm
Leakage of oil from pipelines and oil tankers into seas and oceans is ecologically important and can have significant social and economic impacts on the environment. An early detection of deliberate or accidental oil spills can reduce serious hazards that may threaten coastal residents and help identify pollutants. Iran has been surrounded by seas from the north and the south and they provide u...
متن کاملMatching marine reserve design to reserve objectives.
Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...
متن کاملThe Bioeconomics of Marine Reserves: A Selected Review with Policy Implications
Synopsis: The paper ‘bridges the divide’ between the biological and economic literature on marine reserves. It provides a selected review of the traditional use of reserves, the early reserve literature, the potential benefits of reserves, spillovers from reserves to harvested areas and bioeconomic models of marine reserves. The bioeconomics literature is examined from the perspectives of deter...
