Large hydro-electric dams unviablin emerging economies

摘要

According to Oxford University's Saied Business School, the evidence is conclusive: large dams in a vast majority of cases are not economically viable. Instead of obtaining hoped-for riches, emerging economies risk drowning their fragile economies in debt owing to ill-advised construction of large dams. After a decade-long lull, the construction of large dams has accelerated. Emerging economies of Brazil, China, Ethiopia, Indonesia, and Pakistan among others are rushing to build mega-dams on an unprecedented scale. Yet since 2000, when the World Commission on Dams published its findings, no systematic, global, and independent research has been carried out on the outcomes of large dams. New research from Saied Business School, Oxford has now produced an authoritative investigation of whether large dams work or not, based on the most extensive dataset of its kind.
