Coastal wetlands, including mangroves and coral reefs, absorb the shock and reduce the impact of storm surges and tsunamis on coastal communities. Healthy coral reefs – an estimated 90 percent of which will die off with global warming of 1.5°C – provide double the protection of dead reefs.

Inland wetlands are a natural sponge, absorbing rain, reducing flooding and delaying the onset of droughts by storing excess water.

“We are not powerless to tackle climate change in the little time we have. The solutions are staring us in the face and wetlands are among them. But the world has to fully grasp wetlands’ relationship to climate change. We must start by ending the destruction and degradation of wetlands and restoring lost ones,” urges Martha Rojas Urrego, Secretary General of the Ramsar Convention on Wetlands. 

The benefits of doing so are clear and multi-faceted. For example, by restoring 10,000 of 45,000 hectares of lost mangrove forests, Senegal will store half a million tons of CO2 over 20 years. The world’s largest mangrove reforestation programme will also buffer 200,000 people against storms and strengthen food security through increased rice and fish production.

Denmark, Finland, Iceland, Norway and Sweden’s intensive restoration of the Nordic-Baltic peatlands is part of their efforts to regulate climate change. The draining of 45 percent of these peatlands is responsible for almost 25 percent of the region’s annual CO2 emissions.

In Asia, the storm protection benefits of mangroves in southern Thailand have been valued at USD10,821 per hectare. Mangroves are being restored along the Krabi River Estuary to protect the coastal communities against tropical storms, while Indonesia has committed to restoring two million hectares of peatlands in response to devastating fires in 2015-2016 caused by drought and the draining of peatlands.

Initiatives such as these and others are needed on a far greater scale across the world. Every effort to jointly protect, restore and wisely use all wetlands from now on will matter with each effort multiplying progress towards limiting global warming to below 2°C.

Those efforts will be greatly amplified through including wetlands and the multiple benefits they provide in national policies that address climate change and ensuring the finance is in place for wetland conservation.

At the 13th Conference in November 2018, Parties to the Ramsar Convention resolved on measures to protect, restore and sustainably manage peatlands and coastal ecosystems, acknowledging that these wetlands pull well above their weight in the climate change equation.

“The task facing the world is colossal but not insurmountable. Where there is a will, there is a way. With wetlands, we have a way to save our planet,” says Secretary General Rojas Urrego.
