Dynamic economic valuation of coastal wetland restoration: A nature-based solution for climate and biodiversity

Abstract

This paper explores the dynamic linkage between coastal wetland restoration and the resulting economic benefits, with a focus on nonmarket values such as climate regulation and biodiversity conservation. Coastal wetlands are recognised as highly effective natural carbon sinks, offering significant ecosystem services that contribute to climate change mitigation and adaptation. By utilising a modelling framework that integrates ecological recovery processes and economic valuations over a 100-year period, we provide insights into optimising long-term returns from wetland restoration. This study emphasises the importance of accounting for the temporal dynamics of ecosystem recovery, highlighting the lag between restoration activities and full ecosystem functionality. Our findings highlight the importance of nature-based solutions in global climate finance strategies and emphasise the need for more accurate, targeted investment in wetland restoration. This approach ensures that resources are allocated efficiently over time, maximising the benefits of enhancing coastal resilience and achieving long-term climate goals.
