Tietenberg and Lewis discuss the tragedy of the commons in
Chapter 2, a situation that is exits in many open access fisheries. Explain why is open access fishing a problem
from both an economic and environmental perspective? What policies can be used
to address these problems? Are there government policies intended to help
fisherman that can actually make things worse?
BELOW IS THE ANSWER BUT NEEDS TO BE REWRITTEN PLAGIERISM FREE
Open access fisheries can lead to economic and environmental
problems such as dissipation of economic rent, overpopulation of the fleet,
overexploitation of fish resources, fish stock depletion and even extinction of
fish stock in some cases.
· Regulatory
policies including use rights, regulatory programs by global organizations, and
imposition of taxes can help in overcoming the open access fishery problems.
· Governmental
policies of subsidies, loans, and even taxes can result in exacerbation of the
problems faced by open access fisheries.
In an open access
fishery, there is unrestricted access for fish harvesting, that is, the fishery
is open to all for catching fish. No regulations are imposed on the fishermen
for their participation and fish harvesting amount. As a result of unregulated
access, the number of fish that are harvested exceeds the socially optimal
harvesting level. This subsequently leads to both economic and environmental
problems including dissipation of the economic profits, depletion of fish
stocks, and also extinction of fish stocks. A major manifestation in this
regard, with serious consequences, is observed in the fisheries in high seas,
that is, in ocean areas that are outside the jurisdictional domain of any one
nation.
Fisheries with open access, are likely to lead to extreme
economic and conservational problems. Unregulated exploitation of the marine
resources is a major threat to fisheries regarding their long-term sustainability.
It is to be noted that open access also refers to fisheries,
where the amount of harvesting gear used, nor the number of boats, are
controlled. This unregulated access can be present even if there is regulation
on total catch of fish. In such instances, the fish stocks might not collapse,
but the fleet can become over-excessive due to over-capitalization. Such a
fleet is influenced by economic incentives for entering the fishery and for
investing in larger boats. This overpopulation of the fleet can threaten the
fishery's economic health, in spite of safeguarding the resource.
· Regulatory
policies can be implemented to overcome the problem of open access fisheries.
For instance, use rights can help in open access problems. Use rights are
categorized under property rights (that shows the relationship between
different types of property and people). Use rights are held by the fishermen
for use of the fishery resources, and include access rights and withdrawal
rights of harvesting fish. Access rights provide authorization to entry into
the fishery. Withdrawal rights usually provide rights for taking a specific
catch of fish, or specific level of fishing effort. Also, for maintaining a
high yield of fish, and for protecting young fish, restrictions can be imposed
on gears used for fishing activity. Taxes can be imposed for coping with the
overexploitation in fish harvesting, in open access fisheries.
The serious threat posed by open access fisheries led to the
regulatory efforts on fisheries in the high seas, by the United Nations
Conference on Straddling Fish Stocks and Highly Migratory Fish Stocks. This
program was subsequently followed by the United Nations Fish Stocks Agreement
that implemented the relevant provisions of the UN Law of the Sea.
Some governmental
policies for fishermen can worsen the situation in case of open access
fisheries. Subsidies can augment the open access fishery problems by actually subsidizing
unsustainable fishing practices by the fishermen. Transfers lead to an increase
in the profits of the fishing industry in the short run, but in the long run,
subsidies often result in too many fishers trying to catch from a resource of
few fish. Also, governmental loan programs and tax laws can exacerbate the overcapitalization
problem in an open access fishery.
