Abstract

The Mayur river in Khulna is one of the most polluted rivers in Bangladesh. This study tries to figure out the willingness to pay (WTP) for an improvement in Mayur river's water quality of the people associated with the river and the factors influencing the estimated WTP. Information obtained from 198 respondents of four different river bank areas namely Shonadanga, Gollamari, Mohammadnagar and Sachibunia of Khulna district are analyzed in this study. In light of the Contingent Valuation Method (CVM), a double bounded dichotomous choice model is used to discover the influential factors of respondents' WTP. Around eighty three percent of the respondents said they would like to take part in the Mayur river's water quality improvement program. Although the respondents' preferences for improving the quality of the water show variability, the mostly preferred scenario consists of the third highest improvements of river related attributes among the four improvement scenarios presented to them. Among various predictors, the respondents' years of schooling, monthly household income and living distance from the river are the variables that have statistically significant effect to the change in WTP for improvement program. The mean WTP of the respondents is around BDT 312 (USD 2.57), though the socially and economically optimal tariff rate is BDT 300 (USD 2.47). Only a few of the respondents expressed protest responses and genuine zero responses against this water quality improvement program. In summary, this study finds that majority of the residents close to the river are willing to improve the river water with an affordable cost.

愿意为改善库尔纳马祖尔河的水质付费

库尔纳的马尤尔河是孟加拉国污染最严重的河流之一。本研究试图找出与河流有关的人对改善马乌尔河水质的支付意愿（WTP），以及影响估计WTP的因素。本研究分析了来自库尔纳地区Shonadanga、Gollamari、Mohammadnagar和Sachibunia四个不同河岸地区的198名受访者的信息。根据条件评价法，采用双界二分类选择模型，发现被调查者WTP的影响因素。大约83%的受访者表示，他们愿意参加马祖尔河的水质改善计划。虽然受访者对改善水质的偏好表现出可变性，但最受欢迎的方案是在向他们提出的四种改善方案中，对河流相关属性的改善排名第三。在各种预测变量中，受教育年限、家庭月收入和居住距离是对改善方案WTP变化有统计学显著影响的变量。受访者的平均WTP约为312比索（2.57美元），尽管社会和经济上最优的关税税率为300比索（2.47美元）。只有少数受访者对水质改善计划表示抗议回应和真正的零回应。综上所述，本研究发现大多数靠近河流的居民愿意在可承受的成本下改善河流水质。

期刊介绍： Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action. Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers. All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
