Carbon markets and related international schemes that allow payments to landholders for planting trees, sometimes called carbon farming, are intended to support sequestration of carbon from the atmosphere.
But they will have harmful effects, such as degrading ecosystems and causing food supply problems, if other benefits and disbenefits from revegetating agricultural landscapes are not also taken into account in land-use decisions, according to an article published in the October issue of BioScience.
Brenda B. Lin of the Australian Commonwealth Scientific and Industrial Research Organization and her colleagues assessed a variety of ways that people have attempted carbon farming. Simple maximization of profit can lead landholders accessing carbon markets to create monoculture plantations, which do not support biodiversity and provide few environmental benefits to local inhabitants. But alternatives such as planting strips of trees on farms, agroforestry—integrating trees into cropping systems—and revegetation of marginal or crop land can sequester carbon while also yielding a broad spectrum of environmental benefits.
These benefits may include, for example, reduced pollution outflow and erosion, and better wind protection, pest control, and pollination. What is more, schemes that have local participation and buy-in are more likely to be successful over the long term, because they can draw on local knowledge about trees likely to thrive and will remain popular. Lin and her colleagues urge organizers of carbon farming schemes to move beyond a carbon-only focus and consider cobenefits of revegetation, while involving local inhabitants, not just private landowners, in policy decisions.
BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS; http://www.aibs.org). BioScience is a forum for integrating the life sciences that publishes commentary and peer-reviewed articles. The journal has been published since 1964. AIBS is a meta-level organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations. The article by Lin and colleagues can be accessed ahead of print as an uncorrected proof at http://www.aibs.org/bioscience-press-releases/ until early October.
The complete list of peer-reviewed articles in the October 2013 issue of BioScience is as follows. These are now published ahead of print.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
