Nature-Based Solutions
Storm Surge Reduction by MangrovesBackgroundFlooding and wave energy from storm surges can damage infrastructure and harm inhabitants of coastal communities. Climate change and sea level rise have the potential to increase or intensify storm surges, which necessitate investment in coastal defenses and disaster risk reduction. Mangroves can reduce the effects of storm surges through attenuating waves and wind, making mangroves an important form of nature-based protection for coastal communities.

Reduction of Wind and Swell Waves by MangrovesBackgroundCoastal ecosystems can mitigate the damage from extreme weather events like tropical storms and hurricanes. With human populations increasing in coastal areas, policymakers and stakeholders are interested in coastal ecosystems, like mangrove forests, as a nature-based form of coastal defense and resilience. This report aims to examine the potential for mangroves to reduce wind and swell waves in order to inform decision makers about the potential for mangroves to decrease the risks faced by coastal communities.

Forest carbon in Amazonia: the unrecognized contribution of indigenous territories and protected natural areasBackgroundAmazonia stores an estimated 80–120 Pg of aboveground carbon, and changes in this stock have global climate implications. Indigenous territories (ITs) and protected natural areas (PNAs) together cover roughly one-third to one-half of the Amazon region, yet their specific contribution to maintaining forest carbon has often been overlooked in regional mitigation discussions. Quantifying their role is important for designing REDD+, climate finance, and land rights policies that reflect on-the-ground conservation performance. Open access copy available |

The Evolution of Carbon Market: A Systematic Review and Bibliometric StudyBackgroundCarbon markets are now central to climate policy because governments increasingly rely on carbon pricing to align economic decisions with emission reduction targets. As emissions trading systems and carbon taxes expand in scope and scale, policymakers and researchers need a clear picture of how underlying scholarship has developed and where knowledge gaps remain. Literature on carbon markets has grown rapidly, spanning multiple disciplines, making it difficult to track dominant themes, influential contributions, and blind spots, especially around equity, governance, and Global South experiences.

Realizing the social value of impermanent carbon creditsBackgroundNature-based solutions (NbS) for carbon sequestration provide additional benefits outside of climate change mitigation, such as protecting biodiversity and local livelihoods. However, NbS projects struggle with financing due to challenges demonstrating additionality, avoiding overestimation of carbon storage, establishing metrics to compare NbS with technological projects, and accounting for project impermanence (i.e., the future risk of carbon being released into the atmosphere due to fires, deforestation, disease, or severe weather events).

Enhancing climate change mitigation in protected areasBackgroundProtected areas (PAs) cover roughly 15–17% of the Earth’s land surface and contain a large share of remaining intact ecosystems, many of which store high densities of carbon. With global terrestrial ecosystems absorbing about 3 GtC yr⁻¹, understanding how much of this sink is associated with PAs is important for integrating biodiversity and climate strategies. However, evidence on PA effectiveness for carbon protection, across thousands of sites and multiple biomes, is dispersed and unevenly synthesized. Open access copy available |
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 carbon budget 2013Background“Global carbon budget 2013” updates the living carbon budget series through 2012, documenting continued growth in anthropogenic Carbon dioxide (CO2) emissions and atmospheric concentrations. Atmospheric CO2 rises from about 277 ppm in 1750 to 392.52 ± 0.10 ppm on average in 2012, with daily values exceeding 400 ppm at Mauna Loa in May 2013, symbolizing entry into a new high CO2 regime. The paper positions this trend against persistent fossil fuel dependence and ongoing land-use change, particularly deforestation. Open access copy available |
