Abstract

In this paper we used the Contingent Valuation Method (CVM ) and its variant, the Choice Experiment (CE), to evaluate the willingness of the communities in the Uluguru Mountains (UMs) watershed to pay or accept co mpensation for watershed protection respectively. We intended to inform the debate on whether the Pay ment for Ecosystem Services (PES) model was an effective tool to ach ieve sustainable watershed management in the study a rea. We estimated the potential of the PES model and evaluated the factors which influence willingness to pay (WTP) for the Uluguru watershed conservation and WTAC for upstream co mmun ities. We estimated the potential revenues fro m water charges for do mestic uses in Morogoro Municipality, that could be used to fund the Uluguru watershed program at TZS 31.99 million (US$ 21 326.67) per month or TAS 383.92 million (US$ 255 946.67) annually. The upstream resource managers, who are the major custodian of the Ulu guru watershed would need to be compensated about TZS 100 000 to TZS 400 000 per ha per year depending on the type of co n- servation practices. Overall the results of analysis show that the current pitfalls notwithstanding, there is huge potential for the mo del to reverse the trend of ecosystem degradation in the Eastern Arc Mountains (EAM). To address the existing huddles, the practitioners of the model and local policy makers must work on keeping the public or the watershed conservation beneficiaries informed of the various environmental services they benefit fro m the PES model because they were not aware o f the concept of PES and associated benefits. The study revealed that, a regulatory framework to support compensation schemes for ecological services was required to facilitate the imp lementation of the model at a broader scale.
坦桑尼亚Uluguru流域生态系统服务的支付:买家是否愿意支付,卖家是否愿意接受他们的托管补偿?
本文采用条件评估法(CVM)及其变体选择实验(CE)分别对乌卢古鲁山脉流域社区支付或接受流域保护补偿的意愿进行了评估。本研究旨在探讨生态系统服务付费(PES)模式是否为本研究地区实现可持续流域管理的有效工具。我们估计了PES模型的潜力,并评估了影响乌卢古鲁流域保护的支付意愿(WTP)和上游社区的支付意愿(WTAC)的因素。我们估计了莫罗戈罗市家庭用水收费的潜在收入,这些收入可用于资助乌卢格鲁流域计划,每月3199万塔什(21 326.67美元)或每年38392万塔什(255 946.67美元)。上游资源管理者是乌鲁古鲁流域的主要保管人,根据保护措施的类型,每年每公顷需要获得大约10万至40万古鲁美元的补偿。总体而言,分析结果表明,尽管目前存在缺陷,但该模型在扭转东弧山脉生态系统退化趋势方面具有巨大的潜力。为了解决现有的问题,该模式的实践者和当地政策制定者必须努力让公众或流域保护受益者了解他们从PES模式中受益的各种环境服务,因为他们不知道PES的概念和相关的利益。研究显示,需要一个监管框架来支持生态服务补偿计划,以促进该模式在更广泛的范围内的实施。
