There is a window of opportunity to think on a bigger scale about the role of nature-based solutions in the fight against climate change. Mangroves are one of nature’s most productive carbon assets, sequestering carbon up to 400 per cent faster than land-based tropical rainforests. A regeneration of over 700,000 hectares of restorable potential for mangroves globally would sequester 380 million tonnes of carbon dioxide by 2040. The restoration of mangroves presents an investment requirement of USD11.1 billion over a 20-year period. Not only that, by acting as protective coastal barriers to cities, they save an estimated USD65 billion a year in storm and flood damages.
Projects of mangrove conservation and regeneration provides financial value to investors in small local projects. For example, investment made by a wind power project in Pakistan to restore mangroves on site could return 20 times the value in the protection of physical assets against coastal erosion, saving the project developer and its investors up to USD7 million over the project’s 25-year timeframe.
The report by Earth Security Group presents the analysis, a vision, and the practical proposals and recommendations for nature regeneration to be invested in as a global asset class in a way that can be financed by today’s global capital markets. This would involve creating a municipal fund for climate adaptation, thematically focused on mangrove assets.
