Carbon Stocks and Sequestration
Integrated mangrove-shrimp cultivation: Potential for blue carbon sequestrationBackgroundMangrove deforestation and degradation have increased due to the growth of shrimp farming in tropical coastal environments. This has serious implications for global climate change mitigation, since mangroves are the most carbon-rich forests in the tropics, and converting mangroves into aquaculture ponds increases blue carbon emissions. Integrated mangrove-shrimp cultivation systems can help to prevent mangrove loss and curb blue carbon emissions through pairing shrimp aquaculture with mangrove restoration.

Effects of different management regimes on mangrove ecosystem services in Java, IndonesiaBackgroundIndonesia’s mangrove forests have decreased from 4.5 million hectares (ha) to under 3 million ha since the 1980s, largely due to the lack of monetary value attributed to mangrove ecosystem services, leading to conversion into aquaculture. Developing a valuation system for mangroves that includes both economically valuable products (i.e., timber, food) and ecosystem services allows decision makers to better assess the impacts of management decisions on the important ecosystem services and properties provided by mangroves.

Conservation for production? The benefits of mangroves for sustainable shrimp aquacultureBackgroundIncreasing shrimp demand and declining annual shrimp harvests threaten mangroves in East Kalimantan, Indonesia, due to deforestation from shrimp aquaculture expansion. Silvofishery practices that combine shrimp aquaculture with mangrove conservation are promoted to prevent further mangrove deforestation while still protecting the shrimp farming industry. Mangrove ecosystem services are essential for aquaculture systems to thrive, so it is important to determine successful biophysical elements of silvofishery systems to encourage the development of more sustainable aquaculture practices.

Belize National Forest Monitoring System 2001-2020BackgroundBelize’s diverse ecosystems, land tenure systems, and land-use dynamics require a robust and flexible National Forest Monitoring System (NFMS). Early efforts focused on establishing permanent forest inventory plots in the late 1990s to address data gaps in forest structure and carbon dynamics. Over time, Belize has expanded its forest monitoring framework to integrate both ground-based and remote sensing approaches, ensuring transparency, consistency, and national ownership of forest data systems.

Afforestation and Reforestation Have Varying Biodiversity Impacts Across and Within BiomesBackgroundAfforestation and reforestation (AR) are widely promoted as nature-based solutions (NbS) for carbon dioxide removal and climate mitigation. Global initiatives aim to expand forest cover significantly to meet climate targets. However, AR can produce unintended biodiversity impacts, particularly when implemented in ecosystems such as grasslands or savannas, where native species are not adapted to forest conditions. The ecological outcomes of AR vary across biomes and species, highlighting the need for spatially explicit, biodiversity-sensitive planning frameworks. Open access copy available |
Carbon sequestration in mangrove forestsBackgroundMangrove forests are highly valuable due to the ecological (e.g., sediment deposition, fish nurseries, protection from tropical storms) and economic (e.g., food, fuel) resources they provide. Carbon storage potential in mangroves is also a highly valuable characteristic, especially as a passive method of carbon dioxide capture and storage. In order to protect these important resources and services, it is necessary to create accurate analyses of the global potential and significance of carbon storage in mangroves.

Strong Climate Mitigation Potential of Rewetting Oil Palm Plantations on Tropical PeatlandsBackgroundTropical peatlands store vast quantities of carbon and therefore play a crucial role in global climate regulation. In Indonesia, extensive areas of peatland have been drained and converted to oil palm plantations and other agricultural uses. Drainage exposes peat to oxygen, accelerating decomposition and releasing large amounts of carbon dioxide into the atmosphere. Since degraded peatlands are estimated to contribute significantly to global greenhouse gas emissions, restoration strategies such as peatland rewetting have gained increasing attention as potential natural climate solutions.

Life cycle impacts of forest management and wood utilization on carbon mitigation: knowns and unknownsBackgroundForests currently remove 2-3 GtC yr⁻¹ from the atmosphere, while global wood harvest exceeds 3-4 billion m³ yr⁻¹, creating complex interactions between forest carbon stocks, harvested wood products, and the substitution of wood for more emission-intensive materials. Lifecycle assessment (LCA) is widely used to evaluate these interactions, but differing system boundaries, baselines, and treatment of carbon pools can lead to very different conclusions about mitigation benefits. Clarifying where evidence is robust and where major uncertainties remain is essential for designing coherent forest-climate policy. Open access copy available |
Forest carbon in Amazonia: the unrecognized contribution of indigenous territories and protected natural areasBackgroundAmazonia stores an estimated 80–120 Pg of aboveground carbon, and changes in this stock have global climate implications. Indigenous territories (ITs) and protected natural areas (PNAs) together cover roughly one-third to one-half of the Amazon region, yet their specific contribution to maintaining forest carbon has often been overlooked in regional mitigation discussions. Quantifying their role is important for designing REDD+, climate finance, and land rights policies that reflect on-the-ground conservation performance. Open access copy available |
