The 2030 Mangrove Breakthrough
Invest USD 4 billion to restore and protect 15 million hectares of mangroves by 2030*Why mangroves? Take Action
By 2050, the global community will face annual costs of over $1 trillion to coastal urban areas as a result of the combined effects of rising sea levels and extreme weather events. These impacts are projected to be unequally distributed and certain countries, such as Small Island Developing States (SIDS) and Least Developing Countries (LDCs), are far more exposed and will experience losses in a more extreme manner.
At the centre of the solution to enhancing coastal resilience lies the protection and restoration of coastal ecosystems and biodiversity. Coastal habitats not only help mitigate the impacts of climate change by sequestering carbon and acting as important natural buffers to sea-level rise and storm surges, but they also play a critical role for income, culture, livelihoods, and nutrition security, especially for coastal communities in SIDS and LDCs.
Perhaps the most effective and critical solutions in this respect is the protection of existing natural areas such as mangroves, or coral reefs. Since we have already lost large areas of these ecosystems, protection may not be enough; we need to restore coastal habitats to enhance coastal resilience to face the pressures and changes already underway. Ecosystem restoration is now successful at delivering results over large spatial expanses; it is cost-effective, and can generate social and economic benefits for people where it is employed.
Based on a common understanding of the international science community, the Mangrove Breakthrough goal was defined by scientists from the GMA Science Working Group and the Mangrove Specialist Group using best available geospatial data, and knowledge about finance needs.
* Ensuring sustainable long-term finance for all existing mangroves by achieving an investment of 4 billion USD
** Halting mangrove losses
*** Restoring half of recent mangrove losses
**** Doubling the protection of mangroves globally.
In achieving the Mangrove Breakthrough, we estimate a climate benefit of sequestering over 43.5 million tons of CO2 into mangrove biomass and safeguarding or sequestering an additional 189 million tons of CO2 in the soil.
Restoring half of recently lost mangroves would potentially benefit 37 commercial marine species of fish, crabs, bivalves and shrimp by providing habitat for over 25 billion juveniles each year. And the coastal protection provided by mangroves against flooding and storms – securing lives, infrastructure and economic security – has been estimated to reduce flood risk for over 15 million people and over $65 billion worth of property annually.Learn more

The Mangrove Breakthrough: a call to action for a critical ecosystem
The Global Mangrove Alliance (GMA) in collaboration with the UN Climate Change High-level Champions have identified the need for a unified global approach towards mangrove conservation and calling for signatories to the “Mangrove Breakthrough” being launched today at COP27.READ MORE
A threat and a solution – tourism’s role in mangrove protection
Mangroves are a vital ecosystem that benefit our environment, economy, and communities. Yet they severely under threat. An estimated 67% of historical mangrove habitat has been lost or degraded worldwide, with 20% occurring since 1980. One of the biggest threats to mangroves is the tourism industry. Here’s how we can turn this ship around.READ MORE
Marine Protected Areas: Restoring, preserving, and protecting the integrity and resilience of our ocean for future generations
There is an urgent need to incorporate climate into site management of Marine Protected Areas to help restore, preserve, and protect the integrity and resilience of our ocean for future generations, argues Kristina Rodriguez, Yale School of the Environment.READ MORE
How mangroves protect people from increasingly frequent and powerful tropical storms
Mangrove forests cover just 0.5% of the world’s coasts but account for an estimated 10-15% of coastal carbon capture. As we try to stop CO₂ levels rising and put the brakes on climate change, protecting mangroves for their blue carbon value is key, argues Adam Moolna, Keele University.READ MORE
