Abstract

Ecosystem restoration is a global priority for recovering degraded areas and mitigating climate change. However, climate change can impact the long-term effectiveness of restoration efforts. This study evaluated the effects of climate change on restoration planning, focusing on water quality in the Doce River basin, the site of Brazil’s largest environmental tragedy and the most significant mining disaster globally, with the release of approximately 50 million cubic metres of iron ore tailings into the environment. Sediment exportation was used as a criterion for assessing water quality under three climate scenarios. Restoration of riparian vegetation reduced sediment exportation by 75.29% but was insufficient to fully control erosion, particularly in the upper basin, where increased precipitation could exacerbate the problem. The findings underscore the risks of ignoring climate change in restoration planning. Adaptive strategies are essential to ensure long-term benefits and address climate challenges, fostering more resilient and sustainable ecosystems.

在气候变化中加强水安全的适应性恢复规划。

生态系统恢复是恢复退化地区和减缓气候变化的全球优先事项。然而，气候变化会影响恢复工作的长期有效性。本研究评估了气候变化对恢复规划的影响，重点关注多塞河流域的水质。多塞河流域是巴西最大的环境悲剧和全球最严重的矿难发生地，向环境中排放了大约5000万立方米的铁矿石尾矿。在三种气候情景下，以输沙量作为评价水质的标准。河岸植被的恢复减少了75.29%的泥沙输出，但不足以完全控制侵蚀，特别是在流域上游，降水增加可能加剧问题。这些发现强调了在恢复规划中忽视气候变化的风险。适应性战略对于确保长期利益和应对气候挑战、培育更具复原力和可持续性的生态系统至关重要。
