Economic Costs of Ocean Acidification: A Look into the Impacts on Shellfish Production
Daiju Narita, Katrin Rehdanz and Richard S.J. Tol
Abstract: Ocean acidification is increasingly recognized as a major
global problem. Yet economic assessments of its effects are currently
almost absent. Unlike most other marine organisms, mollusks, which have
significant commercial value worldwide, have relatively solid scientific
evidence of biological impact of acidification and allow us to make such an
economic evaluation. By performing a partial-equilibrium analysis, we
estimate global and regional economic costs of production loss of mollusks
due to ocean acidification. Our results show that the costs for the world
as a whole could be over 100 billion USD with an assumption of increasing
demand of mollusks with expected income growths. The major determinants of
cost levels are the impacts on the Chinese production, which is dominant in
the world, and the expected demand increase of mollusks in today’s
low-income countries, which include China, in accordance with their future
income rise
