Abstract

Urban ecosystem accounting can provide the structure for systematically integrating the value of urban green spaces into management and decision making to support urban resilience and sustainability. However, there are very few instructive examples of urban ecosystem accounting, particularly those created collaboratively with a municipality. Therefore, the aim of this study was to develop co-created urban ecosystem accounts using Tampere, Finland, as a case study. By discussing concrete political and planning-related needs, priorities, and data availability, this study identified urban flooding and the role of green spaces in alleviating this challenge as critical issues. An ecosystem extent account was compiled for accounting years 2012 and 2018 to quantify changes in the extent of ecosystem types. Additionally, an ecosystem service account (physical and monetary), for runoff retention, was compiled for the same years. The runoff retention service was quantified using the InVEST Urban Flood Risk Mitigation model, considering two precipitation events representative of rainstorms that trigger urban flooding. The runoff retention service was translated into service providing areas, which were used in conjunction with service demanding areas to estimate the physical terms of actual flows of retention service for accounting. The monetary value of the service was estimated using the avoided damage cost method. Between 2012 and 2018, the value of runoff mitigation service provided by green spaces increased by 7 % under the 24 mm scenario and by more than 40 % under the 50 mm scenario. The accounts showed concretely how important urban green spaces are in the City of Tampere, and provide an argument to preserve and even increase them in the urban structure. Our experiential ecosystem accounts for urban runoff retention service by green spaces also offer insights to other municipalities, encouraging them to take steps forward in ecosystem accounting.

共同创造城市生态系统核算:城市绿地提供的径流保留服务的物理和货币核算
城市生态系统会计可以为系统地将城市绿地价值整合到管理和决策中提供结构,以支持城市的弹性和可持续性。然而,很少有城市生态系统核算的有益例子,特别是那些与市政当局合作创建的例子。因此,本研究的目的是以芬兰坦佩雷为例,开发共同创建的城市生态系统账户。通过讨论具体的政治和规划相关需求、优先事项和数据可用性,本研究确定了城市洪水和绿地在缓解这一挑战中的作用,这是关键问题。编制了2012和2018会计年度的生态系统范围核算,以量化生态系统类型范围的变化。此外,还为径流保留编制了一个生态系统服务帐户(物质和货币)。使用InVEST城市洪水风险缓解模型对径流保留服务进行了量化,考虑了引发城市洪水的两个具有代表性的暴雨降水事件。径流保留服务被转化为提供服务的地区,这些地区与需要服务的地区一起使用,以估计保留服务的实际流量,以供核算。使用避免损害成本法估算服务的货币价值。2012年至2018年,在24毫米情景下,绿地提供的径流缓解服务价值增加了7%,在50毫米情景下增加了40%以上。这些报告具体地展示了坦佩雷市城市绿地的重要性,并为在城市结构中保护甚至增加它们提供了论据。我们对绿色空间对城市径流保留服务的经验生态系统核算也为其他市政当局提供了见解,鼓励他们在生态系统核算方面采取措施。

期刊介绍: Ecosystem Services is an international, interdisciplinary journal that is associated with the Ecosystem Services Partnership (ESP). The journal is dedicated to exploring the science, policy, and practice related to ecosystem services, which are the various ways in which ecosystems contribute to human well-being, both directly and indirectly. Ecosystem Services contributes to the broader goal of ensuring that the benefits of ecosystems are recognized, valued, and sustainably managed for the well-being of current and future generations. The journal serves as a platform for scholars, practitioners, policymakers, and other stakeholders to share their findings and insights, fostering collaboration and innovation in the field of ecosystem services.
