Industry-driven road-building to fuel Amazon deforestation
(03/12/2008) Unofficial road-building will be a major driver of deforestation and land-use change in the Amazon rainforest, according to an analysis published in Philosophical Transactions of the Royal Society B. Improved governance, as exemplified by the innovative MAP Initiative in the southwestern Amazon, could help reduce the future impact of roads, without diminishing economic prospects in the region.
Photos of rare pygmy hippo in Liberia
(03/12/2008) It's almost as though this normally shy mammal were posing for the camera. The black-and-white image of a pygmy hippopotamus half-facing the camera is the first ever of a pygmy hippopotamus in Liberia. Perhaps even more astonishing EDGE, the organization that accomplished the photo, believes the image to be only the second photographic evidence of the animal in the wild (the first was taken in 2006 in Sierra Leone). This incredibly secretive animal is usually known through its prints and dung.
Cellulosic energy may trigger dramatic collapse in the Amazon
(03/11/2008) Next generation biofuels may trigger the ecological collapse of the Amazon frontier and could have profoundly unexpected economic consequences for the region, warns a paper published in Philosophical Transactions of the Royal Society B. Dr. Donald Sawyer writes that "interacting with climate change and land use, the upcoming stage of cellulosic energy could result in a collapse of the new frontier into vast degraded pasture." The shift could increase the incidence and severity of fires, reduce rainfall in key agricultural zones, exacerbate forest die-back and climate change, and worsen social instability. Sawyer says that while difficult to anticipate, the worst outcomes could likely be avoided be promoting "intensified and more sustainable use" of already cleared areas, minimizing new deforestation, and encouraging "sustainable use of natural resources by local communities."
China's emissions growth 2-4 times greater than expected
(03/11/2008) China's carbon dioxide emissions are growing far faster than anticipated according to according to a new analysis by economists at the University of California, Berkeley, and the University of California, San Diego. The study, published in the Journal of Environmental Economics and Management, estimates China will see an 11 percent annual growth rate in CO2 emissions between 2004 and 2010, two to four times the 2.5 to 5 percent growth rate estimated by the Intergovernmental Panel on Climate Change.

Half of Madagascar's amphibians may still await discovery
(03/11/2008) Madagascar is one of the most unique places on Earth for wildlife. When the public thinks of Madagascar's fauna most likely they think of one of the fifty species of lemur. Yet, Madagascar possesses a wealth of endemic wildlife outside of these unique prosimians. For example, to frog-lovers Madagascar is a paradise. The only amphibians living on Madagascar are frogs; the island is devoid of toads, salamanders, or newts. But what it lacks in other amphibians it makes up for in the number and beauty of its frogs. Currently, 240 frogs have been catalogued in Madagascar, 99 percent of which are endemic. Yet, amphibian expert Dr. Franco Andreone believes that, according to recent field studies, this may only be half of the frogs that actually live in Madagascar. Dr. Andreone believes the final tally could reach 500 species!

Emissions from deforestation offset by increased tree growth in the Amazon
(03/10/2008) An increase in carbon sequestration by trees in the Amazon has roughly offset total emissions from deforestation in the region since the 1980s. A new study, published in Philosophical Transactions of the Royal Society B, this trend may slow in the future, causing the world's largest rainforest to become a net source of carbon emissions and therefore contributing to climate change.

Scientists target safe-climate future
(03/10/2008) Friends of the Earth, Australia, working in conjunction with many of the world's foremost climate scientists recently published a report which should have quickly pervaded into mainstream media. It is a detailed, 100-plus page manifesto imploring immediate, radical action beyond not only the proposed climate change responses by the IPCC, mainstream environmental agencies, and world governments but outside the procedures and proceedings of our national and international authorities. Coverage of the ground-breaking report, however, remains mostly in the realm of climate sites and blogs, absent not only from major sources such as Reuters and Associated Press, but even from major conservation and environmental new sites.

Scientists seek to understand how climate will impact forest carbon
(03/05/2008) Forests contain nearly 40 percent of the world's carbon--more than the atmosphere contains--but too little is known about forest carbon dynamics to predict whether anthropogenic global change will increase or decrease forest carbon pools. Helene Muller-Landau, staff scientist at the Smithsonian Tropical Research Institute, announced a major global research effort to quantify forest carbon pools and fluxes. She announced the new effort at the Climate Change in the Americas Symposium, held Feb. 25-29 at the institute's headquarters in Panama.

Why Europe torpedoed the REDD forests-for-carbon credits initiative
(03/05/2008) Reducing emissions from deforestation and forest degradation (REDD) has been widely lauded as a mechanism that could fund forest conservation and poverty alleviation efforts while fighting climate change. At the December U.N. climate meeting in Bali, delegates agreed to include REDD in future discussions on a new global warming treaty — a move that could eventually lead to the transfer of billions of dollars from industrialized countries to tropical nations for the purpose of slowing greenhouse gas emissions by reducing deforestation rates. conservationists and scientists applauded the decision.

Human impacts on primate conservation in central Amazonia
(03/03/2008) Deforestation in the Amazon is a serious concern. In the Brazilian Amazon, forests are cleared for cattle ranches, soybean cultivation, and selective logging practices. A new plan to settle approximately 180 families north of Manaus, the capital city of the state of Amazonas, has created widespread controversy. The land plots would be located within the study site of the longest-running study of forest fragmentation, the Biological Dynamics of Forest Fragments Project (BDFFP). Therefore, the plan would threaten scientific research at the BDFFP and other nearby research sites operated by the Instituto Nacional da Pesquisas de Amazônia (INPA) and Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA), as well as the future of the Central Amazonian conservation Corridor.

New 'red list' seeks to stave off global seafood collapse
(03/03/2008) Over-fishing and destructive fishing practices have had a considerable effect on oceanic ecosystems. In 2006 a highly-reported study found that without drastic measures all wild seafood will disappear from the oceans in 50 years. Greenpeace, working against such a crash, has started a campaign that highlights 'red fish'. The twenty-two 'red' species are seafood that consumers and suppliers (including supermarkets) should avoid due to their plummeting populations and/or the damage caused by harvesting them.

How accurate is long-term climatology data from the Amazon?
(03/03/2008) With some models forecasting significant change in the Amazon rainforest over the next century, it has been unclear whether the temperature and precipitation data upon which the projections are made is accurate. Now, new research by Rafael Rosolem of the University of Arizona, shows that data associated with the Large-scale Biosphere-Atmosphere Experiment in Amazon (LBA) -- an international research initiative focusing on how changes in land use and climate will affect the biological, physical, and chemical functioning of Amazonia -- is representative of normal climatology for the region. In other words, during most of the LBA data collection period, the data was not taken during severe drought or extreme wet periods.
