Research review shows incentives slow rain forest encroachment
The rate of deforestation in the Brazilian Amazon has declined.
An international team of scientists, including one from Virginia Tech, reviewed published research about policy interventions and commodity market effects, and determined that positive incentives for farmers, counties, and states can do as much to preserve forests as public policies that call for penalties.
"The challenge now is to build upon this progress," the team reports in an article in the June 6 issue of Science. "Some immediate and simple positive incentives for responsible, low-deforestation farmers could be established without major new policies or markets for ecosystem services."
Suggestions include simplified regulatory requirements or discounts on environmental licensing procedures, better terms on pre-harvest packages from commodity suppliers, and lower interest rates or better terms on loans from banks for legally compliant landholders.
"Still, deforestation is only one of the threats to the Amazon region," said Leandro Castello, an assistant professor of fish and wildlife conservation in the College of Natural Resources and Environment at Virginia Tech, a co-author of the review article.
"There is an urgent need to shift the Amazon conservation paradigm to encompass the freshwater ecosystems, which are being rapidly degraded by deforestation and construction of hydroelectric dams," said Castello, who is first author on one of the articles reviewed. "We now know that freshwater ecosystems could be managed through policy and supply chains in a manner similar to that which is being done with deforestation."
Castello, whose specialty is Amazon fisheries, is leading a team from the Woods Hole Research Center and the University of California Santa Barbara, funded by NASA, assessing the impacts on wetlands and river ecosystems caused by extreme climatic events in collaboration with Brazilian scientists.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
