Advancing coastal and mangrove resilience through sustainable nature-based solutions

Overview

Pantai Tanjung Kepah has been severely affected by coastal erosion, leading to the depletion of mangrove forests and the loss of vital marine biodiversity. This degradation has left the coastline highly vulnerable to storm damage. 

To address these challenges, a permeable bamboo wave screen was introduced as a nature-based engineering solution. The structure is designed to restore natural sediment dynamics, improve soil conditions, and support mangrove regeneration. Prior to construction, comprehensive site investigations were conducted, including mangrove, water, and soil sampling, alongside physical and numerical modelling to assess feasibility.

The engineering design was carefully developed, and construction was carried out by a local contractor from Kampung Tanjung Kepah, with active participation from the community in tasks such as collecting branches, filling sandbags, and managing logistics. Post-construction, monitoring and maintenance activities are planned in collaboration with the community, supported by training programmes that equip residents with skills to evaluate the structure’s condition and its ecological impact.

This initiative not only strengthens environmental resilience but also empowers the community by fostering ownership, responsibility, and sustainable resource management, ensuring long-term protection and restoration of Pantai Tanjung Kepah’s coastal ecosystem. 

This presentation highlights innovative approaches to tackling coastal erosion and ecosystem degradation. It begins by framing the urgent challenges faced by vulnerable shorelines, where mangrove loss and sediment imbalance have heightened exposure to storms and biodiversity decline. The core solution presented is the use of permeable bamboo wave screens, a nature-based engineering intervention designed to restore sediment dynamics, improve soil conditions, and support mangrove regeneration.

The presentation outlines the rigorous preparatory work—site investigations, sampling, and modelling—that ensured the feasibility and effectiveness of the design. It emphasises the collaborative construction process, where local communities contributed materials, logistics, and hands-on support, fostering shared responsibility. Post-construction, the programme integrates monitoring and maintenance activities, with training provided to empower residents to assess structural performance and ecological outcomes. This capacity-building element ensures sustainable stewardship and long-term resilience.

Ultimately, the presentation underscores how blending engineering innovation with community participation can safeguard coastal ecosystems, enhance biodiversity, and build adaptive resilience. By promoting ownership and sustainable practices, the initiative demonstrates a replicable model for advancing coastal protection and mangrove restoration through environmentally sound, socially inclusive solutions.
