English
This review synthesizes field and lab studies on eco-engineering and low-carbon materials for coastal defence structures. Increasing substrate surface complexity and using low-binder cements like slag cement (CEM III/B) can enhance biodiversity while preserving engineering performance. It also catalogs cost-effective habitat features (BIOBLOCK, drill-core and artificial rock pools) and identifies evidence, cost-benefit, and data-presentation gaps limiting adoption.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
気候変動適応策としての沿岸インフラ整備は、日本の国土強靱化や港湾・海岸行政と親和的。低炭素コンクリートの採用は建設業のScope 3排出・グリーン調達の論点にも接続し得る。
In the global GX context
Adaptation infrastructure is increasingly part of climate disclosure and transition planning, and low-carbon concrete choices feed directly into construction-sector Scope 3 accounting and green procurement criteria under frameworks like CSRD and ISSB.

📄 Abstract（原文）
With the increasing threats posed by global climate change, artificial coastal structures remain essential to mitigate coastal erosion and flood risks in many regions worldwide. However, these structures are often criticized for introducing non-native materials that disrupt habitats and support lower biodiversity than natural rocks. Over the past three decades, eco-engineering has emerged as a solution to mitigate these impacts while maintaining their protective function. This study analyzes field and laboratory tests in the literature to identify advances in ecological engineering and low-carbon materials for the design of ecologically enhanced coastal structures. Key interventions include increasing surface complexity and heterogeneity of artificial substrates, evaluating the suitability of substrate types for biodiversity enhancement, and developing sustainable bio-enhancing concrete blends. Research highlights that incorporating surface roughness at scales from millimeters to decimeters, coupled with appropriate material selection can significantly enhance biodiversity while maintaining engineering performance. Examples of cost-effective habitat enhancement solutions include the BIOBLOCK unit ($2500 per unit), drill-core pools (€60 per pool), and artificial rock pools (€38 per pool). Concrete, especially with low-binder cements like slag cements (CEM III/B), is a suitable alternative when natural rock is unavailable. In this paper, studies are selected based on their relevance to coastal engineering practices, highlighting areas where further research is needed and offering recommendations to overcome barriers to the effective implementation and broader adoption of more sustainable and multifunctional coastal defences. Challenges include strengthening the evidence on achievable enhancements, clarifying cost-benefit analyzes, and improving data presentation for decision-making.
