Deforestation and Degradation
Global Carbon Budget 2025Background“Global Carbon Budget 2025” extends the living dataset on anthropogenic carbon dioxide (CO2) emissions and their redistribution among atmosphere, ocean, and land, updating trends through 2024, and providing preliminary 2025 estimates. Atmospheric CO2 has risen from about 278 ppm in 1750 to 422.8 ± 0.1 ppm in 2024, with recent growth amplified by the 2023–2024 El Niño event. This paper highlights the continued dominance of fossil fuel emissions, persistent sources of land-use change, and climate-driven modulation of land and ocean sinks within the broader carbon-climate system.

Global Carbon Budget 2024Background“Global Carbon Budget 2024” assesses how anthropogenic carbon dioxide (CO2) emissions disrupt the global carbon cycle relative to pre-industrial conditions, when atmospheric CO2 was about 278 ppm in 1750. The study focuses on emissions from fossil fuels and land-use change and how these are partitioned between the atmosphere, ocean, and terrestrial biosphere. Recent changes, in the context of long-term trends since 1958, emphasize the role of deforestation, fossil fuel combustion, and climate variability, such as El Niño, in shaping CO2 fluxes.

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.

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.

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.

Bridging conservation and policy: evaluating national targets to reduce mangrove loss under the Kunming–Montreal biodiversity frameworkBackgroundThis research examines the alignment between the Kunming–Montreal Global Biodiversity Framework (GBF) targets and national efforts to halt mangrove loss. Under the Convention on Biological Diversity, GBF’s Targets 1 and 3 aim to reduce habitat loss and expand protected areas to conserve 30% of critical ecosystems by 2030. Mangroves, vital for biodiversity, carbon storage, and coastal protection, continue to experience degradation due to both human and natural drivers. Despite partial success in global mangrove protection, national policies often fail to address underlying drivers of degradation or incorporate specific, measurable conservation actions.

The enduring world forest carbon sinkBackgroundForests are critical to mitigating climate change because they absorb atmospheric carbon dioxide (CO₂) and store it in biomass and soils. In 2023, atmospheric CO₂ levels exceeded 420 ppm, intensifying the urgency to understand terrestrial carbon sinks. Forests historically lost 180 Pg of carbon through land-use change, yet they remain central to achieving global net-zero goals by 2050. While remote sensing and modeling offer insights, this study emphasizes long-term, ground-based forest inventory data as the most reliable source for assessing trends in carbon sinks across boreal, temperate, and tropical forest biomes.
