Integrating Nature into Engineered Coastal Structures Enhances Biodiversity and Ecosystem Services

Designing coastal infrastructure with ecological principles, known as Coastal Greening of Grey Infrastructure (CGGI), can significantly boost marine biodiversity and improve ecosystem functions.

Proceedings of the Institution of Civil Engineers - Maritime Engineering · 2024

Key Findings

01CGGI shows significant promise in enhancing marine biodiversity and ecosystem functioning.
02There is a growing evidence base for CGGI, but also criticisms regarding its potential misuse for harmful development.
03A significant knowledge gap exists in translating academic research into practical application outside of developed nations.
04Intersectoral and transsectoral collaboration is needed for knowledge exchange and capacity building in CGGI.

Application

Design takeaway

How to apply

When designing any coastal structure (e.g., sea walls, breakwaters, offshore platforms), actively research and integrate features that encourage colonization by native marine species, such as textured surfaces, crevices, and appropriate material choices.

Project actions

01When researching coastal structures, look for examples where nature has been integrated into the design.
02Consider how your design could provide habitats for marine life.
03Research the specific marine life in the area where your design will be implemented to inform your choices.

Method & Evidence

AimWhat are the current advancements, criticisms, and knowledge gaps in Coastal Greening of Grey Infrastructure (CGGI) for enhancing marine biodiversity and ecosystem services?

MethodLiterature Review

ProcedureThe researchers conducted a comprehensive review of existing literature on CGGI, analyzing its state-of-the-art, identifying common criticisms, and pinpointing areas requiring further research and practical implementation.

ContextMarine and coastal engineering, ecological design, sustainable development

Variables

IV["Design features of coastal infrastructure (e.g., texture, complexity, material)","Presence/absence of ecological integration strategies"]

DV["Marine biodiversity (species richness, abundance)","Ecosystem functioning (e.g., water filtration, habitat provision)","Structural integrity and longevity of infrastructure"]

CV["Location and environmental conditions (e.g., wave exposure, salinity)","Type of grey infrastructure","Time elapsed since implementation"]

Strengths & Limitations

Strengths

+Comprehensive review of a rapidly evolving field.
+Identifies critical areas for future research and practical development.
+Connects design practice to global sustainability goals (UN SDG 14).

Limitations

The current research is heavily concentrated in developed countries, meaning successful strategies may need adaptation for different regions and contexts.

Reliability & validity

The reliability of the findings is high due to the comprehensive literature review methodology. Validity is strong in identifying the state-of-the-art and knowledge gaps, but practical application validity may vary by context.

Think critically

To what extent can the 'greening' of grey infrastructure be considered a genuine ecological enhancement versus a form of 'greenwashing' if not implemented with rigorous scientific oversight?

Design Principles

"Design for ecological integration: Engineered structures can and should be designed to actively support and enhance local ecosystems."

This approach transforms artificial structures into habitats, contributing to broader environmental goals like UN SDG 14. It offers a pathway for designers and engineers to create more resilient and ecologically beneficial coastal developments.

What This Means for Your Design

Making sea walls and other structures in the ocean more 'green' by adding features that help sea creatures live on them can make the ocean healthier and more diverse.

How to use in your project

1.Use this research to justify the inclusion of ecological features in your design, linking it to biodiversity enhancement and ecosystem services.
2.Cite the paper when discussing the benefits of green infrastructure in marine settings.
