気候変動と人為活動により汽水域の塩分侵入が悪化し、飲料水や農業用水の供給に影響を与えている。本レビューは、自然に基づく解決策（NBS）が塩分侵入緩和に有効かを評価し、6つの潜在的なNBSを概念化した。数値モデルによる評価では、これらのNBSが塩分侵入長を低減できる可能性が示されたが、実際の汽水域での適用例は少ない。今後の実装に向けた方向性が提示されている。

Climate change and human activities are exacerbating salt intrusion in estuaries, threatening freshwater supplies. This review evaluates the effectiveness of nature-based solutions (NBS) for salt intrusion mitigation, conceptualizing six potential NBS such as river discharge management and channel modification. Numerical models indicate that these NBS can reduce salt intrusion lengths, but real-world applications remain rare. Directions for future implementation are provided.

In the global GX context
Globally, nature-based solutions are gaining attention as cost-effective adaptation measures for climate change. This review provides a systematic assessment of NBS for salt intrusion, relevant for coastal management and water security policies worldwide, especially under sea-level rise scenarios.
👥 読者別の含意
🔬研究者:Researchers in estuarine dynamics and nature-based solutions can use the conceptualized NBS types and numerical assessment as a foundation for further studies.
🏢実務担当者:Water managers and coastal engineers may consider the proposed NBS for pilot projects, though real-world validation is still limited.
🏛政策担当者:Policymakers involved in climate adaptation planning can note the potential of NBS for salt intrusion, but should be aware of site-specific conditions.
📄 Abstract（原文）
Abstract Climate change and anthropogenic activities are enhancing salt intrusion in many estuaries, which reduces the supply of drinking water as well as freshwater for agricultural and industrial uses and can further cause severe economic losses. Nature‐based solutions emerge as sustainable and ecologically sound strategies to mitigate salt intrusion in estuaries. This review paper explores the effectiveness of nature‐based solutions in salt intrusion mitigation. Advances in the understanding of estuarine salt dynamics are summarized, thus identifying the dominant parameters that determine the salt intrusion in different types of estuaries. Six potential nature‐based solutions (NBSs) for salt intrusion mitigation are conceptualized, including improvement of river discharge management, reduction of channel cross‐section, modification of bottom topography, utilization of friction‐convergence balance, enlargement of intertidal area and introduction of meanders. These NBSs are grouped into two types: (a) advection‐based and (b) mixing‐based. Numerical model assessments indicate that all these NBSs have potential to reduce salt intrusion lengths, depending on the salinity structure of the estuary. Nevertheless, applications of NBSs to real estuaries are rare. Directions toward improving the implementation of nature‐based solutions for mitigating salt intrusion in estuaries are provided.
