Abstract

Living streams are an important element of decentralised stormwater management solutions. They are actively promoted due to their ability to generate multiple ecosystem services, including water quality improvement, biodiversity protection and aesthetics. However, a lack of monetised values of ecosystem services of living stream projects makes it difficult to assess the net benefits of investing in such projects. This study uses the hedonic pricing method to estimate the capitalised amenity values of living streams and other public open spaces (POS) in housing and lot markets for the first time. The study area includes two newly greenfield-developed suburbs in the Perth metropolitan area. We find the positive impact of living streams and other POS on the house and lot prices. However, living streams generate greater value than other types of POS. Furthermore, the POS (including living streams) that support active recreation are valued more than basic POS without active recreation features. Finally, we observe, for the first time, that the benefits of planned but not yet constructed POS (including living stream) are similar to the completed POS (including living stream) in both housing and lot markets. This information is useful for policymakers and developers making informed decisions about water-sensitive urban infrastructure.

多功能水敏感型城市基础设施的资本化非市场效益:以河流为例
生活溪流是分散式雨水管理解决方案的重要组成部分。由于它们能够提供多种生态系统服务,包括水质改善、生物多样性保护和美学,因此受到积极推广。然而,由于缺乏活流项目生态系统服务的货币化价值,很难评估投资于此类项目的净收益。本研究首次使用享乐定价方法来估计住房和地块市场中生活流和其他公共开放空间(POS)的资本化舒适度价值。研究区域包括珀斯大都会区两个新开发的绿地郊区。我们发现生活流和其他POS对房价和地块价格的积极影响。然而,生活流比其他类型的POS产生更大的价值。此外,支持主动娱乐的POS(包括生活流)比没有主动娱乐功能的基本POS更有价值。最后,我们首次观察到,在住房和地块市场中,规划但尚未建设的POS(包括生活流)的效益与已建成的POS(包含生活流)相似。这些信息有助于决策者和开发商就水敏感的城市基础设施做出明智的决策。
