There is growing concern globally to conserve natural systems including watersheds due to increasing forest degradation and deforestation. The Barekese and Owabi watersheds provide several ecosystem services to communities, health facilities and industries. The watersheds are found in a rapidly degrading environment due to increasing anthropogenic activities. This paper addressed the neglected, but critical, question of the importance of watershed ecosystem services. The objective of the study was to determine willingness of households in downstream communities to pay for watershed conservation and the drivers of WTP. Households were willing to pay a mean of $1.5 ± 0.2 additional on their monthly water bills. Quotations for Willingness to pay varied from as low as $0.02 to as high as $ 20.58 per month. Age, household size and years of residence were significantly related with willingness to pay, amount to pay and reasons for protest bids. The younger generations and women were ready to pay extra amount for watershed management. The results indicated that downstream communities are willing to support conservation and that demographic factors influence the amount people are willing to pay. The concept of WTP is useful and applicable to conservation of watersheds in the tropics through the design and implementation of PES schemes. It also provides important information for conservation and development policies related to watershed management in developing countries.
由于森林退化和森林砍伐的加剧,全球对包括流域在内的自然系统保护的关注日益增加。巴雷凯塞和奥瓦比流域为社区、卫生设施和工业提供了多种生态系统服务。由于人为活动的增加,这些流域处于快速退化的环境中。本文探讨了被忽视但至关重要的流域生态系统服务重要性问题。该研究的目的是确定下游社区家庭为流域保护付费的意愿以及支付意愿的驱动因素。家庭愿意在每月水费上平均额外支付1.5±0.2美元。支付意愿的报价从低至每月0.02美元到高达20.58美元不等。年龄、家庭规模和居住年限与支付意愿、支付金额和抗议出价的原因显著相关。年轻一代和女性愿意为流域管理额外付费。结果表明,下游社区愿意支持保护,并且人口因素会影响人们的支付意愿。支付意愿的概念通过设计和实施生态系统付费计划,对于热带地区流域的保护是有用且适用的。它还为发展中国家与流域管理相关的保护和发展政策提供了重要信息。
