The paper estimates the total value for the community of the cleanup of the Buriganga River. Dhaka, the capital of Bangladesh, was developed on the bank of the Buriganga River in the early 1600s. The river is now near dead mainly due to human interventions. The paper develops a hypothetical cleanup programme to improve the water quality, which will help the overall environment in and around the river. The value of this programme is estimated within the framework of total economic value; non-marketed benefits are measured through a contingent valuation survey and marketed benefits are estimated using market and shadow prices. The findings of the survey suggest that not only are a significant proportion of the residents willing to pay for the cleanup programme, but many are also willing to contribute in non-monetary ways (mainly their time). When the latter contribution is monetised, it represents 60% of the total value for the non-marketed benefits. The marketed benefits are estimated to represent 58% of the overall value of the cleanup programme (18.6 million US dollars/year). A failure to account for all benefits could lead to a gross underestimation of the desirability of providing public funding for the cleanup of dying rivers.
该论文估算了布里甘加河清理工作对社区的总价值。孟加拉国首都达卡于17世纪初在布里甘加河畔发展起来。这条河如今几近枯竭,主要是由于人类干预。该论文制定了一个假设性的清理计划以改善水质,这将有助于河流及其周边的整体环境。该计划的价值是在总经济价值框架内估算的;非市场效益通过意愿调查估值法衡量,市场效益则使用市场价格和影子价格估算。调查结果表明,不仅有很大比例的居民愿意为清理计划付费,而且许多人还愿意以非货币方式(主要是贡献时间)做出贡献。当将后者的贡献货币化时,它占非市场效益总价值的60%。市场效益估计占清理计划总价值的58%(每年1860万美元)。未能考虑所有效益可能会导致严重低估为清理濒死河流提供公共资金的可取性。
