Abstract: With the rising vulnerability of coasts due to climate change, nature-based solutions including mangrove restoration are increasingly recognised as a sustainable and cost-efficient alternative for protecting at-risk coastal areas. Owing to their functionality and persistence, mangroves contribute to flood mitigation and the ecosystem’s adaptability to climate shifts, offering advantages over conventional hard infrastructure designed for coastal protection. Yet, implementing mangrove-based flood reduction strategies is complex and often faces challenges attributed to a combination of ecological, social, and technical factors. In response to these challenges, we propose the development of multi-functional eco-engineered marine units that can support mangrove growth in areas where traditional restoration is difficult or impractical, while also delivering additional economic, social, and biodiversity benefits. This paper does not aim to provide detailed designs; rather, it presents a conceptual framework for various mangrove-based eco-engineering structures intended to support mangrove growth and resilience and enable their establishment in a wider range of coastal environments. By evaluating design criteria, feasibility, and ecological benefits, this work offers foundational guidance for the development and scaling of mangrove-based eco-engineering solutions for coastal protection, biodiversity, and socio-economic benefits.
