Abstract

Ecosystem accounting is increasingly used at national and regional levels to guide environmental management. Nonetheless, there is a lack of accurate data on individual ecosystems, which hampers the reliability of upscaling analyses critical to understanding human impacts on ecosystems. Delta areas are particularly challenging due to the complex and unique ecological characteristics created by human activities interacting with aquatic and terrestrial domains.

This study aims to address this gap by compiling a comprehensive set of ecosystem accounts that cover extent, condition and services at the individual ecosystem level. In particular, the applicability of the System of Environmental-Economic Accounting – Ecosystem Accounting (SEEA-EA) framework will be evaluated in the context of a restoration project at the Sacca di Goro lagoon, a coastal brackish lagoon located in the Po delta (Northern Italy).

The analysis shows that the SEEA-EA can effectively capture the impact of various factors, including environmental measures, socio-economic trends, climate change, and biological invasions, on an individual ecosystem. The environmental interventions resulted in a significant restoration of reed habitats and an improvement in the abiotic characteristics. However, other drivers acting at different scales had negative impacts on biotic indicators. The decline of the fishery in the Adriatic region, along with climate change and the recent invasion of blue crabs, has significantly impacted the fish community and clam farming, resulting in the loss of valuable provisioning services such as fishery and aquaculture.

The case of the Sacca di Goro lagoon demonstrates that local measures can enhance ecological conditions and some regulating services but other larger-scale factors may have relevant and unexpected impacts. To scale up the analysis at a national or regional level, further research on individual ecosystem types is necessary, especially in the case of deltas and estuaries.

应用于咸水沿海泻湖恢复的生态系统核算凸显了单个生态系统层面研究的重要性

生态系统核算越来越多地被用于国家和地区层面，以指导环境管理。然而，由于缺乏有关单个生态系统的准确数据，这妨碍了对人类对生态系统的影响进行可靠性分析。三角洲地区由于人类活动与水生和陆地领域相互作用而形成了复杂而独特的生态特征，因此尤其具有挑战性。本研究旨在通过汇编一套全面的生态系统账户来填补这一空白，该账户涵盖了单个生态系统层面的范围、状况和服务。分析表明，环境-经济核算体系-生态系统核算（SEEA-EA）框架可有效捕捉各种因素（包括环境措施、社会经济趋势、气候变化和生物入侵）对单个生态系统的影响。环境干预措施显著恢复了芦苇生境，改善了非生物特征。然而，其他不同规模的驱动因素对生物指标产生了负面影响。亚得里亚海地区渔业的衰退，加上气候变化和最近蓝蟹的入侵，对鱼类群落和蛤蜊养殖产生了重大影响，导致渔业和水产养殖等有价值的供给服务丧失。萨卡迪戈罗泻湖的案例表明，当地措施可以改善生态条件和某些调节服务，但其他更大规模的因素可能会产生相关的、意想不到的影响。为了在国家或区域层面扩大分析范围，有必要对个别生态系统类型开展进一步研究，尤其是在三角洲和河口的情况下。

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.
