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.

Decreasing landscape carbon storage in western US forests with 2 °C of warmingBackgroundThis study investigates how a 2°C increase in global mean temperature above pre-industrial levels could alter above-ground carbon storage in forests across the western United States, a region already experiencing climate-driven tree mortality, reduced regeneration, and more frequent fire and insect outbreaks. Forest carbon density is treated as a “carbon carrying capacity” controlled by climate and disturbance regimes, and there is concern that warming and drying will shift many areas towards lower carbon forest or non-forest states, with implications for climate mitigation and carbon offset 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 |
Resilience to Hurricanes is High in Mangrove Blue Carbon ForestsBackgroundWhile many anthropogenic forces threaten the survival of mangrove forests, tropical storms are the most significant non-anthropogenic sources of disturbance. Since mangroves are important carbon sinks, it is important to understand the impacts of tropical storms on mangrove forest structure, function, and carbon stock recovery.

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.

How feasible are global forest restoration commitments?BACKGROUNDMany countries pledged large pieces of land for Forest Landscape Restoration to the Bonn challenge and the UNFCCC Paris Accords. The highest pledges came from the global South. Two countries have met their Bonn challenge so far. Some countries are facing challenges including deficit of the land committed, and there are competing land uses between FLR agricultural land. Open access copy available |
Leverage points for improving global food security and the environmentBACKGROUNDMeeting global food demands is still a challenge, yet agriculture has been one of the main driving forces of greenhouse gas emissions. Hence, this study focused on identifying small regions, actions that can be taken and crops with a potential of increasing global yields, with an efficient system of food delivery and reducing the negative impacts of agriculture on the environment.

The role of ecological theory and practice in poverty alleviation and environmental conservationBackgroundThis review emphasized the roles and tools of ecologists that would be helpful in poverty alleviation internationally. Specifically, knowledge of sustainable sources of energy, provision of clean water, functional traits of vegetation, and design of agro-forestry systems were cited as examples of knowledge that would be helpful for cross-disciplinary strategies.
