Researchers found that Indigenous Territories are as effective as Protected Areas in preserving forest's carbon stocks, with some areas showing up to 10% more carbon storage. The study suggests that securing land titles and formalizing forest co-governance can bring multiple benefits for both indigenous people and national governments.
A study found that fires in the Amazon's wettest areas destroy small and medium-sized trees, leading to a loss of biomass and carbon stocks. The destruction can last for decades, with saplings and bushes being among the first to die.
New research suggests that the Arctic's increasing plant biomass is not enough to absorb large amounts of carbon dioxide, as most of it is released through fires and timber harvests. The study estimates that only 430 million metric tons of biomass have accumulated over 31 years, with much of it being lost due to wildfires.
Researchers at the University of California - Riverside have developed an energy-efficient way to convert corn stover into activated carbon for water treatment. The process produces activated carbon that absorbs up to 98% of vanillin from water, showcasing a promising approach to combating climate change by repurposing idle resources.
A microbial community with small diversity was found to efficiently clean up algal blooms through the bacterial degradation of specific polysaccharide substrates. The study revealed a limited spectrum of important polysaccharide classes, primarily alpha- and beta-glucans, which are made up of basic components.
Researchers found that re-burned areas experienced significant biomass loss and a six-fold decrease in tree seedling density. The study suggests that future short fire intervals may adversely affect the resilience of subalpine forests, threatening their ability to recover from previous fires.
A recent study found that species-rich subtropical forests can absorb up to twice as much carbon as monocultures, showcasing the importance of biodiversity in forest productivity. Reforestation with a variety of tree species is recommended to promote both ecological and economic benefits.
Researchers at ETH Zurich found that soil microorganisms degrade films composed of poly(butylene adipate-co-terephthalate) (PBAT), a biodegradable polymer. This discovery demonstrates the true biodegradation of a plastic material in soils, offering a potential solution to plastic pollution.
A global biomass census yields 550 Gt C, with land biomass surpassing marine by two orders of magnitude. Human activities have led to significant reductions in wild mammal, fish, and plant biomass.
A 20-year study found that C3 grasses actually lose biomass under elevated CO2 levels, while C4 species gain significantly, contradicting previous expectations. This reversal has significant implications for modeling future climate and accurately estimating the distribution of these plant species globally.
Researchers at Idaho National Laboratory have developed a new fuel cell technology powered by solid carbon, which can utilize three times as much carbon as earlier designs. The innovation enables lower temperatures and higher power densities, making it potentially more efficient than conventional hydrogen fuel cells.
A recent study reveals that tree cover on agricultural land has increased globally, capturing vast amounts of carbon dioxide and potentially playing a significant role in mitigating climate change. The research highlights the importance of agroforestry systems in reducing greenhouse gas emissions from agriculture.
A University of Queensland-led study assesses the amount of carbon stored in tropical forests recovering after land-clearing practices in the Philippines. Regenerating secondary forests are substantial carbon sinks, increasing their capacity to store carbon with abandonment age.
Lianas slow tree growth and reduce aboveground carbon uptake by over three-quarters, threatening carbon storage capacity. This reduction can lead to a positive feedback loop, accelerating climate change.
Researchers discovered that coccoliths can modulate solar light, enhancing photosynthesis in microalgae. The study found that magnetically oriented coccoliths change light scattering, contributing to understanding how these structures control light.
A new UC Berkeley study shows that combining biomass electricity production with carbon capture and sequestration can store more carbon than emitted, making the western US a critical contributor to an overall zero-carbon future. The technology could reduce emissions by up to 80% by 2050 and even become carbon-negative.
A Dartmouth-led study finds that logging can release large amounts of carbon stored in deep forest soils, potentially offsetting the benefits of using wood for energy. The research suggests that increased reliance on forest biomass may actually increase atmospheric carbon dioxide levels.
Researchers developed a new randomization protocol to accurately estimate total biomass in forests. The GLAS approach shows promise in standardizing global forest biomass inventory and improving spatial and temporal coverage.
Researchers at Iowa State University have discovered a genetic method to boost algae biomass by 50-80 percent, enabling the production of more efficient biofuels. The breakthrough involves expressing two genes that increase photosynthesis in the plant, leading to increased organic matter production.
A recent report provides new ideas on the carbon and energy benefits of forests and forest products. Sustainably managed forests can store and substitute carbon, while forest biomass-based energy uses less stored carbon, reducing fossil fuel emissions.
The National Biomass and Carbon Dataset (NBCD) provides unprecedented spatial resolution of 30m, offering comprehensive assessment of forest structure and carbon stock within the lower 48 States. This dataset will advance understanding of US natural resources, biodiversity conservation, wildfire risk assessment, and timber production.
Scientists at Oregon State University found that Pacific Northwest forests have significant potential to increase carbon storage, with estimated increases of 15% if all forest stands were allowed to increase in age by 50 years. This region accounts for 14% of the live biomass in the entire US and has already sequestered 30-50% of emiss...
Scientists have released the first national biomass and carbon dataset, which provides high-resolution estimates of forest biomass and carbon stock. The dataset, known as NBCD2000, is being made available for download on a zone-by-zone basis and offers valuable information for quantifying the carbon stock in U.S. forests.
The new H2CAR process produces three times more biofuels from the same biomass, reducing carbon dioxide emissions and increasing efficiency. This could provide sustainable fuel for all US transportation sectors without additional land use.
Researchers generate high-resolution dataset of vegetation canopy height, aboveground biomass, and carbon stocks for the US in 2000. The dataset will enable unprecedented quantification of biomass and carbon stocks, improving studies on climate interactions, forest fire mitigation, and wildlife habitat characterization.
