Small fires a big threat to Amazon rainforest biodiversity
(02/27/2008) Small fires have a big impact in the Amazon rainforest, report researchers writing in Philosophical Transactions of the Royal Society B. The findings suggest a dire future for Earth's largest rainforest.
Half the Amazon rainforest will be lost within 20 years
(02/27/2008) More than half the Amazon rainforest will be damaged or destroyed within 20 years if deforestation, forest fires, and climate trends continue apace, warns a study published in Philosophical Transactions of the Royal Society B. Reviewing recent trends in economic, ecological and climatic processes in Amazonia, Daniel Nepstad and colleagues forecast that 55 percent of Amazon forests will be "cleared, logged, damaged by drought, or burned" in the next 20 years. The damage will release 15-26 billion tons of carbon into the atmosphere, adding to a feedback cycle that will worsen both warming and forest degradation in the region. While the projections are bleak, the authors are hopeful that emerging trends could reduce the likelihood of a near-term die-back. These include the growing concern in commodity markets on the environmental performance of ranchers and farmers; greater investment in fire control mechanisms among owners of fire-sensitive investments; emergence of a carbon market for forest-based offsets; and the establishment of protected areas in regions where development is fast-expanding.
Web site offers homepage for every one of Earth's species
(02/27/2008) Monumental may be the only way to properly describe the Internet's Encyclopedia of Life. Its creators have set themselves the task of gathering accurate and detailed information on the earth's known 1.8 million species until every tree, arachnid, rodent, and even virus will have its own in-depth webpage.
$100 billion worth of carbon released from deforestation in Riau, Sumatra
(02/27/2008) A WWF study found that deforestation of nearly 10.5 million acres of tropical forests and peat swamp in central Sumatra's Riau Province over the past 25 years has generated 3.7 gigatons of carbon dioxide. Based on today's $32 closing price for a ton of carbon dioxide for European Union Allowances, the emissions had a theoretical trading value of $118 billion, assuming they could have been traded at the full E.U. carbon price at the time (voluntary offsets would have been worth about $13 billion).
Complete map of world forests to help REDD carbon trading initiative
(02/27/2008) Policymakers, conservationists and scientists have high hopes that REDD, a mechanism for compensating countries for reducing emissions from deforestation and forest degradation, will spur a massive flow of funds to tropical countries, helping preserve rainforests and delivering economic benefits to impoverished rural communities. To date, one of the biggest hurdles for the initiative has been establishing a baseline for deforestation rates -- in order to compensate countries for "avoided deforestation" it first must be known how much forest the country has been losing on a historical basis. Until now, with some notable exceptions, this data was based largely on spotty satellite assessment and surveys of national forestry departments by the U.N. Food and Agricultural Organization.
Organic fertilizers could fight global warming
(02/27/2008) Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, according to new research published in a special issue of Waste Management & Research (Special issue published today by SAGE).
A Doomsday Vault for Frogs?

Soil erosion: the future of Easter Island
(02/25/2008) Today the saga that is Easter Island's past is well known. The tragic circumstances that led to the downfall of its early civilization through starvation and war are of epic proportions. Many scientists agree that the real life scenario born from this isolated island serves as a warning, about the interrelatedness between scarcity of natural resources and conflict, for all mankind. However, current natural resource practices suggest that this lesson has fallen on deaf ears.
Rainforest logging threatens endangered sea turtles
(02/25/2008) Logging is having an unexpected impact on endangered sea turtles in Central Africa, reports a new study published in Oryx. Aerial surveys in Gabon reveal that logs lost during transport are clogging beaches, preventing critically endangered leatherback turtles (Dermochelys coriacea) from nesting.
Reducing deforestation rates 10% could generate $13B in carbon trading under REDD
(02/25/2008) Cutting global deforestation rates 10 percent could generate up to $13.5 billion in carbon credits under a reducing emissions from deforestation ("REDD") initiative approved at the U.N. climate talks in Bali this past December, estimate researchers writing in Philosophical Transactions of the Royal Society B. But the researchers caution there are still substantial obstacles to overcome before carbon-credits-for-rainforest-conservation becomes a reality.

Is Guyana's logging deal in its best interests?
(02/21/2008) In January Guyana awarded U.S. timber firm Simon & Shock International a 400,000-hectare (988,400-acre) logging concession near the Brazilian border. Final approval hinges on the completion of an environmental impact survey and a tree inventory. While Simon & Shock International says it plans to conduct selective logging, the firm has not announced whether it will seek Forest Stewardship Council certification, a mark for responsibly-harvested timber. Is there an alternative that can improve the lot for the average Guyanese? There may be. Last fall Guyana's President, Bharrat Jagdeo, hinted at the potential of using the country's forests as a giant carbon offset to counter climate change.
