In Photos: Blue Carbon Around the World

From Senegal to Indonesia, conservation groups are linking coastal restoration to the climate change movement

Back in 2009, a new term entered the conservation lexicon: “blue carbon.” The phrase was coined by a handful of United Nations agencies to describe the carbon stored in coastal ecosystems. Mangroves, seagrasses, and salt marshes, they were discovering, are incredible sponges for the greenhouse gas, storing up to five times more per acre than rainforests do. They are also disappearing much faster than rainforests, mainly due to coastal development, conversion into shrimp ponds, and timber harvesting. Those changes not only release what one blue carbon enthusiast dubs “nuclear bombs of carbon,” they also strip coastal communities of their buffer against sea and storms, destroy vital fish nurseries, and harm essential habitat for species ranging from marsh mongooses to monkeys. Since the 1960s, scientists say the world has lost around half of its mangroves and tidal marshes.

Environmental groups around the world are using payments they receive for the “blue carbon” that these coastal ecosystems capture to fund conservation projects. Conservation International, which has worked to protect Bird’s Head, is a leader in this push.

Conservation groups quickly realized that by linking coastal restoration to the climate change movement, and especially to carbon credit funding schemes, they could turbo-charge efforts to protect these ecosystems. A handful of local and international organizations have already put the idea into action. In at least five countries, corporate investors like Danone and Michelin are funding mangrove restoration to offset their carbon emissions.

Not everyone is enthusiastic about these projects. Critics like the 10-million-strong World Forum of Fisher Peoples worry that communities will lose access to food and fuel if coastal areas are cordoned off for the climate’s sake – as has happened with some terrestrial carbon forestry projects in the past, sparking a heated debate over the legitimacy of the carbon credit concept. But Emily Pidgeon, a senior scientist at Conservation International and a strong proponent of blue carbon, is confident these problems can be overcome. “The lessons are out there in the carbon community,” she says. “We in the marine community need to be actively working out how to apply them when they’re wet.”

The organization is experimenting with carbon credits at two sites in Madagascar. To compensate for the income these communities may lose due to not selling mangrove wood, the group has launched sea-cucumber aquaculture, beekeeping, and ecotourism projects, along with alternative fuel plantations. “We want to ensure that blue carbon makes financial sense for communities,” says Blue Ventures’ Leah Glass. “It won’t be a long-term success [otherwise].”

The up-front payments made by Danone and other companies to the Livelihoods Fund translated into 150 million trees planted in delta communities like this one on the island of Niodior.

The community-led project is called Mikoko Pamoja, which means “mangroves together” in Kiswahili. School kids visit the sites on field trips and benefit from the funds it brings in.

A recent study led by the nonprofit Counterpart International found that in the country’s northwest corner, converting mangroves into shrimp ponds was creating huge per-acre carbon emissions. The study prompted the government to include mangroves in its national climate change strategy, or NAMA – the first time that has happened anywhere.

In the meantime, it is teaching college and high school students how to measure blue carbon. Here, Oregon State University ecologist Boone Kauffman shows students the deep soil where most of the carbon is stored.

 Shrimp farming has devastated mangroves in Vietnam, too. A coalition of government and conservation groups working with farmers in the Mekong Delta considered selling carbon credits to fund restoration, but ultimately decided organic shrimp certification would be an easier and more profitable way to protect mangroves.

 The Naturland organic certification guarantees a high price for shrimp, but also requires that mangrove forest cover half the farming area. That has led to 200 acres being replanted, and about 31,000 acres protected from clearing since 2013. The project is called Markets and Mangroves.

The model hasn’t been applied yet in the US, largely because carbon prices typically aren’t high enough to offset the costs of carbon credit validation and restoration work here. But NOAA science advisor Ariana Sutton-Grier says that if carbon prices rise, blue carbon could be a “game changer” for urgently needed coastal conservation.

Glad to see community-led mangrove and coastal management getting the attention it deserves. We need more science like the results Counterpart International has captured that has resulted in government’s engagement and support. Now to get global carbon markets to move more funds to community-led management efforts.
