Mangrove Restoration and Its Ecological Consequences

Mangrove restoration has garnered significant global attention in recent years due to its immense capacity for carbon sequestration, role as a natural pollution sink, and provision of numerous ecological and economic benefits. As a key element of the United Nations Sustainable Development Goals (SDGs), ecosystem restoration is critical for addressing climate change, poverty alleviation, and biodiversity conservation.

Nature-based solutions—such as the conservation and restoration of blue carbon ecosystems—are increasingly recognized as effective strategies for achieving targets outlined in the Paris Climate Agreement. Accordingly, many countries are actively developing or updating national plans for mangrove restoration to enhance the management, resilience, and sustainability of coastal ecosystems.

Mangrove restoration is a fast-evolving field, underpinned by robust commitments to coastal protection, biodiversity conservation, and climate mitigation. However, while the benefits are many, large-scale mangrove restoration and reforestation efforts may also result in unintended and complex ecological consequences in coastal zones. These can include changes in sediment dynamics, carbon cycling, pollution levels, microbial functions, hydrological regimes, native species composition, and trophic interactions.

Understanding both the advantages and potential drawbacks of mangrove restoration is essential for designing effective and ecologically sound restoration strategies. This Special Issue aims to provide a platform for research that explores the multifaceted ecological consequences of mangrove restoration.
