Aboveground and belowground tree biomass and carbon stocks in the miombo woodlands of the Copperbelt in ZambiaBackgroundMiombo Woodlands occupy an estimated 2.7 million km² across southern Africa and support millions of people through fuelwood, charcoal, and non-timber products, while also storing substantial carbon. In Zambia’s Copperbelt Province, woodland conversion and degradation for charcoal and agriculture risk reducing carbon stocks, but local biomass values are poorly constrained, leading to uncertainty in national estimates and REDD+ baselines. This study responds to the need for site-specific biomass and carbon data in one of Zambia’s most industrialized and heavily used miombo regions. 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 |
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.

Herbaceous plant diversity in forest ecosystems: patterns, mechanisms, and threatsBACKGROUND:Recent studies have expanded our ecological understanding by focusing on forest herbs, highlighting that while trees dominate ecological theory, they represent only a small fraction of forest plant diversity. Forests showcase varying plant diversity due to human activities like land-use changes, invasive species, climate change, and overabundant herbivores, necessitating comprehensive management strategies. By understanding the complex interplay of these factors, the research aims to promote effective long-term conservation and sustainability of herbaceous plant communities in these environments.
