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 |
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.

Between a rock and a hard place: The burdens of uncontrolled fire for smallholders across the tropicsBackgroundThe growing prevalence of uncontrolled tropical landscape fires significantly threatens tropical forests and causes substantial social and economic burdens. These burdens continue to be largely overlooked in favor of aggregate-scale losses like climate change and biodiversity, despite the severe local impacts on smallholder farming communities across the forested tropics. Furthermore, people often unfairly portray smallholders as the primary culprits of fire contagion due to their customary fire-based agricultural practices. This narrative is rooted in colonial-era condemnations. Open access copy available |

Complementary ecosystem services from multiple land uses highlight the importance of tropical mosaic landscapesBackgroundTropical agricultural landscapes feature a mosaic of diverse land uses, yet the ecosystem service bundles and materials they provide to rural households remain poorly understood. In northeastern Madagascar, shifting cultivation for hillside rice production and agroforests for cash and subsistence crops have largely replaced old-growth forests. The landscape consists of forest fragments, small-scale vanilla agroforests, rice paddies, and subsistence farming plots at various stages of the shifting cultivation cycle.

The eco-evolutionary history of Madagascar presents unique challenges to tropical forest restorationBackgroundMadagascar forests contain high biodiversity and species endemism, while also being heavily threatened by deforestation. Restoration of these forests may be unique to many other restoration projects due to the unique evolutionary history of the island. Goals and MethodsThe authors conduct a literature review of publications to determine if forest restoration in Madagascar is more challenging. With compiled literature from 1990 to 2022, the authors consequently describe unique challenges to Madagascar forest restoration in order to facilitate higher quality restoration projects.

A cautionary note for forest landscape restoration in drylands: cattle production systems in northwest Madagascar’s dry forestsBACKGROUNDIt is evident that land tenure security is crucial for successful restoration. Unfortunately, in Madagascar, dry forests are considered unoccupied and unowned even when communities have long-established claims under customary tenure systems. The authors stated that collective tenure recognition efforts were underway in Madagascar, but limited knowledge of agropastoralist cattle production strategies impeded the efforts to develop tenure reforms. The authors examined how cattle raisers in the Boney Region in northwest Madagascar organize pastoral spaces and cattle production strategies in the area’s dry forest. Open access copy available |
Distribution and genetic diversity of five invasive pests of Eucalyptus in sub-Saharan AfricaBACKGROUNDPlantation forestry in Sub- Saharan Africa has been characterized by an introduction of several Eucalyptus species because of their socio- economic benefits. However, these Eucalyptus trees have been affected by non- native foliage feeding insect pests, which have been accidentally introduced, resulting in stunted growth and in some cases mortality. The rate of introduction of non-native eucalypt-feeding insects globally has increased nearly five-fold between the 1980s and 2010s. Open access copy available |
