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 |
Getting the best of carbon bang for mangrove restoration buckBackgroundMangrove forest restoration projects have a range of benefits, like carbon sequestration, biodiversity conservation, and sustainable development, that are important for different stakeholders. An analysis of the economic benefits and returns of mangrove restoration at country-level scales can encourage future support from these key investors and decision makers.

Drivers of global mangrove loss and gain in social-ecological systemsBackgroundThe gain and loss of mangrove forests worldwide depends on both biophysical factors and socioeconomic factors. With global mangrove cover decreasing since the 1990s and biophysical pressures on mangrove forests (i.e., shoreline erosion, extreme weather events) increasing due to climate change, it is important to understand which forms of national conservation policies, programs, governance, and local economic activity most rapidly reverse the rate of loss of mangrove forests.

Current trends and future directions for integrating social values into mangrove restorationBackgroundDifferent communication styles, governance, and social issues create barriers to successful mangrove forest restoration projects, and may hinder the ability to scale up projects to meet global restoration goals. Incorporating social values and stakeholder preferences into restoration projects can help identify best management practices, promote successful outcomes, and prevent distrust and inequality between restoration practitioners and stakeholders with different needs and perceptions of mangrove forests.

The drivers and impacts of Amazon forest degradationBackgroundThis research examines the growing threat of forest degradation across the Amazon, a region critical to global carbon balance and biodiversity. Beyond deforestation, widespread disturbances such as fire, edge effects, selective logging, and extreme drought have emerged as major causes of ecological and social disruption. These human-driven stressors, intensified by climate change, now affect approximately 2.5 million km²—around 38% of remaining Amazon forests—posing risks comparable to deforestation itself.
