Forests' long-term potential for carbon offsetting
April 15, 2008As well as cutting our fossil fuel emissions, planting new forests, or managing existing forests or agricultural land more effectively can capitalise on nature's ability to act as a carbon sink. Research published online in the open access journal Carbon Balance and Management shows that although planting trees alone is unlikely to solve our climate problems, large-scale plantations could have a significant effect in the longer term.
Rik Leemans and colleagues from Wageningen University, the Netherlands and the Netherlands Environmental Assessment Agency modelled the future effects of carbon plantations. They estimated plantations' long-term physical and social sequestration potential up to the end of the 21st century, and their effectiveness in slowing down the increase in atmospheric CO2.
The projected outcomes differ widely: the authors found a difference of nearly 100% in the sequestration potential up to 2100 between two baseline scenarios. This highlights the effect of future land use uncertainties. Social, economic and institutional barriers preventing carbon plantations in natural vegetation areas decrease the plantation's sink potential by 75% or more. Nevertheless, the forest's potential should not to be underestimated: Even the most conservative assumptions suggest that the cumulative sequestration potential up to 2100 can compensate for 5-7% of energy and industry related CO2 emissions.
However, trees aren't a quick fix, Leemans cautions. "The potential for the coming decades is limited due to the limited amount of available land and the long period needed to compensate for emissions related to the establishment of the plantations. "The net sequestration up to 2020 is limited, given the short-term increased need for agricultural land and the long period needed to compensate for emissions through plantation establishment."
The most effective plantations occur in tropical regions, whereas the effectiveness of high latitude plantations is more questionable. Although plantations have a considerable carbon sink potential, the authors say that these should form part of a broader package of options, including reducing energy CO2 emissions.

Carbon Sink Current Events and Carbon Sink News RSSArctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide.
Scientists say climate change mitigation strategies ignore carbon cycling processes of inland waters
In the paper, The Boundless Carbon Cycle, published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud™ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player - inland waters.
Time to lift the geoengineering taboo
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering - deliberate interventions in the climate system to counteract man-made global warming - more seriously.
World's last great forest under threat: new study
The world's last remaining "pristine" forest - the boreal forest across large stretches of Russia, Canada and other northern countries - is under increasing threat, a team of international researchers has found.
Carbon sinks losing the battle with rising emissions
The stabilising influence that land and ocean carbon sinks have on rising carbon emissions is gradually weakening, say scientists attending this week's international Copenhagen Climate Change Conference.
U.N. Climate Change Conference considers ancient soil replenishment technique in battle against global warming
Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive.
Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.
Carbon sinks: Issues, markets, policy
With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2.
Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS).
Amazon powers tropical ocean's carbon sink
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study.

Carbon Sinks and Climate Change: Forests in the Fight Against Global Warming (Advances in Ecological Economics) by Colin A. G. Hunt (Author) Reforestation and avoiding deforestation are methods of harnessing nature to tackle global warming - the greatest challenge facing humankind. In this book, Colin Hunt deals comprehensively with the present and future role of forests in climate change policy and practice. The author provides signposts for the way ahead in climate change policy and offers practical examples of forestry's role in climate change mitigation in both developed and tropical developing countries. Chapters on measuring carbon in plantations, their biodiversity benefits and potential for biofuel production complement the analysis. He also discusses the potential for forestry in climate change policy in the United States and other countries where policies to limit greenhouse gas emissions have been... |

Deforestation: Tropical rainforest, Climate change, Intergovernmental Panel on Climate Change, Carbon sink, Interception (water), Loess Plateau, Timeline of environmental events by John McBrewster (Editor), Frederic P. Miller (Editor), Agnes F. Vandome (Editor) "Deforestation is the logging and burning of trees in a forested area. There are several reasons for doing so: trees or derived charcoal can be sold as a commodity and are used by humans while cleared land is used as pasture, plantations of commodities and human settlement. The removal of trees without sufficient reforestation, has resulted in damage to habitat, biodiversity loss and aridity. Also deforested regions often degrade into wasteland. Disregard or unawareness of intrinsic value, and lack of ascribed value, lax forest management and environmental law allow deforestation to occur on such a large scale. In many countries, deforestation is an ongoing issue which is causing extinction, changes to climatic conditions, desertification and displacement of... |

Harnessing Farms and Forests in the Low-Carbon Economy: How to Create, Measure, and Verify Greenhouse Gas Offsets by Zach Willey (Editor), Bill Chameides (Editor) As the United States moves to a low-carbon economy in order to combat global warming, credits for reducing carbon dioxide emissions will increasingly become a commodity that is bought and sold on the open market. Farmers and other landowners can benefit from this new economy by conducting land management practices that help sequester carbon dioxide, creating credits they can sell to industry to “offset” industrial emissions of greenhouse gases. This guide is the first comprehensive technical publication providing direction to landowners for sequestering carbon and information for traders and others who will need to verify the sequestration. It will provide invaluable direction to farmers, foresters, land managers, consultants, brokers, investors, regulators, and others... |
