BlueShore Project assesses how Brazilian mangroves capture carbon, promoting global strategies for soil preservation and health.
Brazilian mangroves have emerged as environmental superheroes by capturing surprisingly large amounts of carbon, playing a crucial role in the battle against climate change. These ecosystems have the incredible ability to sequester three to five times more carbon per hectare compared to the Amazon rainforest. Projects such as BlueShore, led by RCGI since 2021, are exploring their potential, establishing global strategies for the preservation of these habitats. In addition to storing carbon, mangroves also promote biodiversity, protecting coastlines and contributing to the conservation of biodiversity. soil health.
In parallel, the mining sector has sought to align itself with sustainable practices. Since 2025, the extractive industry has taken steps towards automation and energy transition, committing to reducing environmental impacts. Sustainable initiatives in this sector are not only necessary, but are now a primary focus for conscious growth. The goal is to create a harmonious balance between mining and mangrove conservation, integrating practices that minimize harm and maximize environmental benefits. Interestingly, some projects promote the idea that mining can coexist, and even thrive, alongside mangrove conservation efforts.
How Industry and Nature Are Moving Together
One notable example is the collaboration between environmental NGOs and mining companies, which began in 2023, which seeks to protect mangroves while optimizing mineral exploration. As recently as September 2023, experts in ecology and mining came together to discuss innovative tactics that could reshape the future of both sectors. Approaches are being developed that include cutting-edge technology to monitor and manage resources more effectively. With these innovations, the aim is not only to protect ecosystems, but also to generate skilled jobs, such as ESG (Environmental, Social and Corporate Governance) leaders.

Furthermore, local communities have an active voice in this process, with community consultancies being essential in guiding sustainable mining practices in the vicinity of mangroves. Since 2022, mining companies have invested in training programs to directly involve these groups, ensuring that their knowledge and traditions are respected. Boosting the local economy…

The Powerful Role of Mangroves
Mangroves stand out as one of the most effective natural areas for absorbing carbon, playing an essential role in reducing greenhouse gases and mitigating climate change. To better understand their carbon capture potential and its significance for the environment, the project called BlueShore – Blue Carbon Forests for Offshore Climate Change Mitigation launches a comprehensive study through the Research Centre for Greenhouse Gas Innovation (RCGI). This project is dedicated to measuring and analyzing the capacity of these forests along the Brazilian coast, contributing to the formulation of global preservation strategies and restoration. With an area of around 1 million hectares, Brazil is the second country with the largest area of mangrove forests.
Environmental Variability and Importance
O BlueShore focuses its studies on varied conditions These ecosystem formations along the extensive coastline, which stretches from southern Brazil to the Amapá region, are directly influenced by soil conditions and their various forms, which profoundly impact the mangroves' ability to retain carbon. 'One of our main goals is to meticulously estimate the carbon capture potential and build a database that fills the information gaps in various regions,' says Tiago Osório Ferreira, coordinator and professor of the Department of Soil Science at the Luiz de Queiroz College of Agriculture (ESALQ-USP). According to Professor Ferreira, mangrove forests can sequester three to five times more carbon per hectare than the Amazon Rainforest.
Multiple Benefits of Mangroves
In addition to their carbon sequestration capacity, mangroves provide several other benefits. ecosystem services, such as protecting coastal areas from erosion and providing habitats for various marine species. With R$8 million in funding from PETRONAS Petróleo Brasil Ltda. (PPBL), the project also seeks to uncover the environmental impacts resulting from changes in land use over the last few decades, which vary from one region to another. For example, in northern Brazil, pasture creation for livestock farming directly modifies the mangroves, while in the Northeast, shrimp farming is the most notable impact, and in the Southeast, urbanization.
Challenges and Solutions
Understanding how these changes affect carbon reserves is vital to developing future recovery strategies adapted to each soil type, maximizing the capacity to sequester carbon. BlueShore has specific objectives such as studying the mechanisms of carbon sequestration and stabilization in soils, where more than 80% of the carbon sequestered by mangroves remains stored. The project also aims to create a soil health index to categorize more or less degraded regions and investigate how mangrove biodiversity reacts to increasing CO2 concentrations, along with opportunities to integrate these ecosystems into the carbon credit market, linked to the robust ecosystem.
Collaborative Efforts for the Protection of Mangroves
The multidisciplinary team that makes up the BlueShore, composed of 11 professors and 11 researchers from different institutions, such as ESALQ-USP, Federal University of Ceará (UFC), Federal University of Espírito Santo (UFES), among others, works to achieve these objectives. The project is at the heart of the Program Nature-Based Solutions (NBS), an English expression for Nature-Based Solutions coordinated by RGCI/ESALQ, aiming to reduce greenhouse gases by increasing carbon sequestration in the soil. Despite their strong resilience to adverse conditions, mangroves are vulnerable to human actions.
Final Considerations and Economic Impacts
Such actions, such as the transformation of mangrove areas into pastures, affect their natural recovery. 'Mangroves adapt easily to a variety of situations, but they are not invincible, especially when compared to more competitive ecosystems,' adds Costa. Preserving mangroves is not only crucial for carbon capture, but also generates sources of income for countless communities through the provision of ecosystem services, which, translated into monetary values, exceed 90 thousand dollars per hectare, annually. 'Protecting mangroves is essential not only in environmental terms, but also because of the economic and social impact they represent for countless families,' concludes Ferreira.
