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.

Elevation, aspect, and climate shape blue pine (Pinus wallichiana) biomass and carbon dynamics in the Bhutanese HimalayasBackgroundForests cover over two-thirds of Bhutan and are constitutionally protected, enabling national carbon neutrality. Yet, climate change, increasing temperatures, variable precipitation, and heightened wildfire risk threaten carbon storage capacity and species distributions. Blue pine is a fast-growing, socio-economically important species dominating inner dry valleys between roughly 2200–3000 m, making it an ideal model to understand how elevation and slope aspect regulate biomass accumulation and carbon sequestration under changing climate conditions.

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 |
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.

Tree species that ‘live slow, die older’ enhance tropical peat swamp restoration: Evidence from a systematic reviewBackgroundHighly degraded forests often require active reforestation, which presents additional challenges with species selection for tree plantings. In tropical peat swamp forests, where harsh environmental conditions threaten seedling survival, various seedling and site treatments can enhance seedling survival and growth in restoration projects.

Carbon dynamics with stand structure and species diversity in the Hindu Kush Himalaya ranges of PakistanBackgroundGlobal climate change and biodiversity loss underscore the importance of forests in climate change mitigation and ecosystem stability, as highlighted by UN Sustainable Development Goals 13 and 15. The Hindu Kush Himalaya region in Pakistan is a critical biodiversity hotspot and a significant carbon reservoir. However, the relationships among forest structure, species diversity, and carbon storage in this region remain poorly understood, particularly under current management exclusions and anthropogenic pressures.
