In partnership with Conservation International and Colombian Communities, Apple is protecting and restoring the mangrove forests in Cispatá Bay (Colombia) - This story was originally published by Apple. The article can be found here.

The roots of a mangrove tree are like veins. They rise up and plunge down into the salty waters of Cispatá Bay in Córdoba, Colombia, along the coast of the Caribbean Sea, sprawling in every direction. A series of channels have formed an arterial highway connecting to the Sinú River, providing single-lane access into and out of the mangroves where fishermen and loggers begin their day’s work.

“Right now we have a lot of people working on opening channels to keep the water flowing,” says Luis Roberto Canchila Avila, president of Asoamanglebal, the first mangrove association in San Bernardo del Viento in Córdoba. “Because we are in summer, there are parts where the water flow is different and fish die as they are left without oxygen.” It’s a delicate balance: too much river water or too little salt water, and the mangroves could be destroyed.

Below the waterline of these coastal ecosystems, soil and sediment capture and store carbon for centuries. Mangroves can store up to 10 times more carbon per acre than a typical terrestrial forest.

The mangroves have long been a lifeline for the coastal communities of Colombia. They protect them from storm surges and provide food and wood supplies to families. They are also a lifeline for the world, sucking carbon out of the atmosphere and storing it deep in their soil below water for centuries. Recent studies show they can store up to 10 times the amount of carbon per acre as land-based forests.

But pressures from illegal farming, fishing and logging combined with climate change are threatening their existence. “There are many illegal groups working in the mangroves,” Canchila Avila says. “They don’t know or care for the sustainability efforts.” According to Conservation International, when degraded or destroyed, mangroves and other coastal ecosystems emit the carbon they have stored for centuries into the atmosphere and become sources of greenhouse gases. They estimate that as much as 1 billion metric tons of CO2 are being released annually from degraded coastal ecosystems. That’s equivalent to the total annual emissions from cars, buses, aircraft and boats in the US in 2017.

The Cispatá marine protected area in Córdoba, Colombia includes a 27,000 acre mangrove forest divided into zones that indicate when mangrove workers can use a particular area.

Local fishermen in Cispatá Bay navigate the channels that lead into and out of the mangroves hauling the day’s catch. Common fish in the area include snapper, snook, mojarra and sábalo.

On this humid, sunny April morning, Cispatá Bay is still, save for a few local fishermen waist deep in the sea casting their hand-woven nets. Here, Conservation International and Invemar Research Institute are collecting mangrove soil samples to be analyzed for carbon stored in sediment below the waterline, known as “blue carbon.” Together with the Omacha Foundation, the three organizations are designing a carbon financing model to incentivize conservation and restoration of mangroves in the region, working in partnership with the local government environment authority (CVS) and the local communities.

For Apple’s Earth Day 2018 Give Back campaign, Apple partnered with Conservation International to protect and restore the 27,000-acre mangrove forest in Cispatá Bay, which is expected to sequester 1 million metric tons of CO2 over its lifetime. At the Global Climate Action Summit last September in California, Apple’s Vice President of Environment, Policy and Social Initiatives Lisa Jackson underscored the importance of this type of preservation. “These forests are critical because they’re one of nature's most important tools in the battle against climate change,” she said. “Globally, we’ve lost half of the world’s mangrove forests since the 1940s — so it’s high time we start preserving and protecting them.”

Conservation International’s project is the first in the world to fully quantify blue carbon credits in both trees and soil, and will be a model for scaling carbon sequestration in global mangrove ecosystems and curbing emissions caused by deforestation in these areas.

“We are pioneering this new wetland model,” says María Claudia Díazgranados Cadelo, marine biologist and director of Marine and Community Incentive Programs at Conservation International. “We need to strengthen the way we measure carbon stocks in the soil component of the mangroves. Other methodologies only use above-ground biomass without taking much consideration of the soil, which for mangroves and other coastal ecosystems is the most important place where those ecosystems store carbon.”

CVS field assistant José Gregorio Padilla Bautista takes a 50 cm soil sample and carbon stock reading in the Cispatá Bay mangroves.

For an accurate soil sample, Conservation International and Invemar’s field team uses a sediment core sampler to extract a depth of 50 cm and measure carbon stocks and length of time it’s been stored.

Beyond the bay, there are hundreds of families living and working with the mangroves. The mangleros, as they are called, are part of a network of local mangrove associations formed to conserve and protect the mangroves as well as the communities that rely on them for food and income.

In the neighboring town of San Antero, Cispatá native Ignacia De La Rosa Pérez, manages the relationship between the community and the nonprofit organizations through the Independent Mangrove Association. “I was practically born in the mangroves,” De La Rosa Pérez says. “When I was a little girl I began to lead expeditions into the woods and explore life. I didn’t know I was a leader, but everyone followed me. That’s how I began leading movements.”

Since 1976, De La Rosa Pérez has collected decades of data on the mangroves, including details on the animals that live there, the health of the mangroves and the channels that run through them. Binders of maps and in-depth analysis on the characteristics of these coastal trees line two bookshelves in her home office. She holds the greatest collection of data on the region since long before Cispatá Bay was classified as a Marine Protected Area Subsystem, the terms of which also reside in a few binders in De La Rosa Pérez’s home.

Cispatá native and Independent Mangrove Association community representative Ignacia De La Rosa Pérez has been key to the monitoring and recording the state of the Cispatá Bay mangroves since the 1970s.

“We saw the shift in the mouth of the river,” De La Rosa Pérez says. “We saw changes in the ecological processes from the animals to the forest. Everything continued to change, and finally one mangrove that had been there for three or four centuries shifted onto the land, so as time went by, people began to sustain themselves from the mangroves.”

As De La Rosa Pérez recalls, the community would sell whatever they could: wood, tree bark, fish and crabs. So when a local politician tried to label the mangrove workers as ecological predators, De La Rosa Pérez was enraged. While the mangrove workers were accused of destroying the trees through their fishing and logging practices, the reality is the trees were actually dying on their own.

“We’ve begun to speak a new language, a cross between the language of the professionals, of technicians and scientists, and the language of the community.”

“When I was 3, we would compete to see who could find the biggest tree that was buried,” De La Rosa Pérez says. “The mangrove had disappeared, maybe because of the salinity or lack of tributaries. That experience resulted in an answer in ’92 … I went out to the salt mines with the mangrove workers. They dug out the dirt with their hands and with shovels. They pulled up the tree to prove they hadn’t cut it down.”

That proof laid the groundwork for a long-term alliance between the local community and CVS, establishing a set of sustainable practices for using the mangroves. Among them is a rotation plan for leveraging the mangroves from only one designated area at a time so that each zone has time to recover and restore itself.

“We’ve begun to speak a new language,” De La Rosa Pérez explains, “a cross between the language of the professionals, of technicians and scientists, and the language of the community. That’s what made us grow and be able to reach the place that we all are in today.”

The community program to shift hunters into custodians has resulted in the rehabilitation and release of nearly 10,000 crocodiles over the last 18 years that are now nesting in the wild.

Twenty-five miles east of San Antero in San Bernardo del Viento, Asoamanglebal’s Canchila Avila is managing a similar relationship between the community, the local organizations and local government. While Canchila Avila coordinates the sustainable cutting and clearing of mangroves to maintain water flow, he also assigns permits for cutting wood to be sold for construction purposes. “We take from the mangroves but we’re also preserving them,” Canchila Avila says. “If we find an area with very few trees, we know that it needs rehabilitation and it needs to recuperate. We let that area restore and we add trees.”

“We know the area and we know the height of the river, so we used to cut without any prior technical knowledge just because we grew up watching how it was done,” Canchila Avila says. “Today we combine technical knowledge from CVS with our experience.”

A crew of local loggers returning from an afternoon in the mangroves carrying cut and trimmed mangrove logs to be sold for construction in the neighboring towns.

Canchila Avila, De La Rosa Pérez, Díazgranados and a team of marine biologists and environmentalists are all on the frontlines of these conservation efforts. Without the knowledge and experience of the mangleros, preserving the mangroves would be almost impossible.

“They are our right hand in terms of conservation efforts,” Díazgranados says.

The root between the people of Cispatá Bay and the mangroves runs deep. So much so, that every year, the Festival of the Donkey during Holy Week serves as a reminder. Based on a biblical tale retold through the lens of a local puppeteer, masked donkeys carry a man to the town square where he is sentenced to death for his crimes and must read his will. In it, he declares: “To the people of the mangroves, I leave the mangroves.”

While mangroves thrive in saltwater, increasing pressures from agriculture activity and climate change are threatening their existence. Their preservation is a vital key to fighting climate change for generations to come.
