Abstract

Effective water policy requires good information. The System of Environment-Economic Accounting Ecosystem Accounting (SEEA-EA) organises information on ecosystems and the interactions with the economy. We investigate how accounting for water-related ecosystem services (ES) using SEEA-EA could provide information for water policy and management, using the integrated water resource management (IWRM) framework and a case study from the Australian Capital Territory (ACT). A policy review and consulting process linking ACT water policies to SEEA-EA identified three key issues, water security, water quality, and soil erosion, which are evident in many parts of the world. Available data and models were used to account for three ES related to these issues: water supply, soil and sediment retention (soil erosion control), and water purification (nutrient retention). Modelled estimates varied but were broadly consistent and used to construct ES accounts. The accounts provide comprehensive information linking the ecosystems supplying ES to the use of ES in economic production and consumption. This supports five ACT water policy actions and three of the four IWRM Principles. The accounts suggest investment in catchment restoration and management in the Queanbeyan River Catchment to increase ES and improve water supply and quality. The accounts show how much of water is available (IWRM Principle 1), and recognise water as an economic good (IWRM Principle 4) by identifying the uses of water by industry and households. The accounting also enables a participatory approach to water development and management (IWRM Principle 2) by providing stakeholders with information for informed decision-making. Because the policy issues in the case study are common, and IWRM is widely adopted, there is potential to use SEEA-EA for water policy and management globally.

核算与水相关的生态系统服务,为水政策和管理提供信息:澳大利亚案例研究
有效的水资源政策需要良好的信息。环境经济核算体系生态系统核算(SEEA-EA)组织了有关生态系统及其与经济相互作用的信息。我们利用水资源综合管理 (IWRM) 框架和澳大利亚首都地区 (ACT) 的案例研究,探讨了利用 SEEA-EA 核算与水相关的生态系统服务 (ES) 如何为水政策和管理提供信息。将澳大利亚首都地区水资源政策与 SEEA-EA 联系起来的政策审查和咨询过程确定了三个关键问题:水安全、水质和土壤侵蚀,这些问题在世界许多地方都很明显。利用现有数据和模型对与这些问题相关的三个 ES 进行了核算:供水、土壤和沉积物保持(水土流失控制)以及水净化(养分保持)。模型估算结果各不相同,但大体一致,并用于构建生态系统服务账户。这些账户提供了全面的信息,将提供 ES 的生态系统与经济生产和消费中 ES 的使用联系起来。这为澳大利亚首都地区的五项水政策行动和四项水资源综合管理原则中的三项提供了支持。账户建议对昆比扬河集水区的集水区恢复和管理进行投资,以增加生态系统服务并改善供水和水质。核算显示了可用水量(水资源综合管理原则 1),并通过确定工业和家庭的用水情况,将水视为一种经济物品(水资源综合管理原则 4)。通过为利益相关者提供决策信息,水量核算还有助于采用参与式方法进行水资源开发和管理(水资源综合管理原则 2)。由于案例研究中的政策问题很常见,而且水资源综合管理已被广泛采用,因此有可能在全球范围内将 SEEA-EA 用于水资源政策和管理。

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.
