Mapping tropical forest degradation with deep learning and Planet NICFI dataBackgroundForest degradation, driven by logging, fire, and infrastructure expansion, represents a major yet under-detected source of carbon emissions in tropical forests. Unlike deforestation, degradation involves partial canopy loss and is difficult to capture using conventional remote sensing due to small-scale disturbances and rapid vegetation recovery. Existing global products often underestimate degradation or fail to attribute its causes. Advances in high-resolution satellite imagery and deep learning provide new opportunities to improve detection accuracy. Open access copy available |

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.

Mangroves protect coastal economic activity from hurricanesBackgroundWith more frequent and severe weather events anticipated due to climate change, coastal communities are interested in practical coastal defense interventions to protect their public and private assets and prevent disruptions to economic activity from tropical storms. Studies have documented mangrove forests’ ability to reduce wave action, wind velocity, and storm surge, making mangroves a cost-effective form of coastal protection. Yet, the relationship between how large a mangrove belt must be to provide significant protection and how mangroves mitigate tropical storm effects and economic damages is still unknown.

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 |
Global Significance of Mangrove Blue Carbon in Climate Change MitigationBackgroundMangrove forests sequester proportionately greater amounts of carbon than most terrestrial environments. However, natural greenhouse gas (GHG) fluxes from these ecosystems and the carbon released when they are degraded counteract their carbon sequestration potential. Therefore, it is necessary to examine carbon stocks, rates of carbon sequestration, and carbon losses from these environments to clarify the global and regional potential of mangrove forests to mitigate climate change.

Global potential and limits of mangrove blue carbon for climate change mitigationBackgroundDespite national and international policy organizations’ interest in blue carbon financing for mangrove conservation, there is a lack of investment in payments for ecosystem services from the commercial sector. To encourage future investments and scale up blue carbon projects, it is necessary to address knowledge gaps on the financial return on investment for blue carbon projects.

Refining the Global Estimate of Mangrove Carbon Burial Rates Using Sedimentary and Geomorphic SettingsBackgroundPrevious research has focused on calculating accurate estimates of global mangrove carbon stock, while lacking studies examining global patterns of organic carbon (OC) burial. Mangrove forests are naturally highly variable, existing in different sedimentary (i.e., terrigenous- or carbonate-dominant) and geomorphic (i.e., delta, estuary, lagoon, open coast) environments. In addition, different anthropogenic factors affect their structure. Therefore, it is necessary to examine how the spatial variability of mangrove sedimentary and geomorphic settings affects global OC burial estimates. Open access copy available |
Factors influencing organic carbon accumulation in mangrove ecosystemsBackgroundMangrove forest sediments can store a significant amount of organic carbon (900 Mg ha-1). Environmental and anthropogenic impacts, like storms or deforestation, can increase or decrease carbon accumulation rates within mangrove sediments and ecosystems. Therefore, it is important to understand how these impacts affect blue carbon ecosystems’ storage capacity. Open access copy available |
