(04/05/2011) Mangroves may be the world's most carbon rich forests, according to a new study in Nature Geoscience. Measuring the carbon stored in 25 mangrove forests in the Indo-Pacific region, researchers found that mangroves forests stored up to four times as much carbon as other tropical forests, including rainforests. "Mangroves have long been known as extremely productive ecosystems that cycle carbon quickly, but until now there had been no estimate of how much carbon resides in these systems. That's essential information because when land-use change occurs, much of that standing carbon stock can be released to the atmosphere," explains co-author Daniel Donato, a postdoctoral research ecologist at the Pacific Southwest Research Station in Hilo, Hawaii.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Rich plant diversity leads to increased productivity, ecosystem services
(03/08/2011) A new study finds that diversity of plant species matters—big time. Analyzing nearly 600 research studies, the meta-study in the American Journal of Botany found that productivity in biodiverse plant ecosystems was 1.5 times higher than in monocultures. In other words, a prairie is more productive than a cornfield and forest more productive than a rubber plantation. The researchers warn that eroding plant diversity threatens essential ecosystems services such as food, water purification, oxygen production, carbon sequestration, and the availability of raw materials.
Amount of carbon absorbed by ecosystems each year is grossly overstated, says new study
(01/17/2011) According to a new paper published in Science, current carbon accounting methods significantly overstate the amount of carbon that can be absorbed by forests, plains, and other terrestrial ecosystems. That is because most current carbon accounting methods do not consider the methane and carbon dioxide released naturally by rivers, streams, and lakes. This new paper suggests that rivers, streams, and lakes emit the equivalent of 2.05 billion metric tons of carbon every year. (By comparison, all the terrestrial ecosystems on the world’s continents are thought to absorb around 2.6 billion metric tons of carbon each year). This is, as the lead author of the paper said, is a “major accounting error”.
Carbon sequestration: Underground storage of carbon dioxide may trigger earthquakes
(12/14/2010) Underground storage of carbon dioxide may trigger earthquakes which could allow the gas to seep back into the atmosphere, rendering the emissions mitigation approach ineffective, warns Stanford geophysicist Mark Zoback.
Tropical agriculture "double-whammy": high emissions, low yields
(11/02/2010) Food produced in the tropics comes with high carbon emissions and low crop yields, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). In the most comprehensive and detailed study to date looking at carbon emissions versus crop yields, researchers found that food produced in the tropics releases almost double the amount of carbon while producing half the yield as food produced in temperate regions. In other words, temperate food production is three times more efficient in terms of yield and carbon emissions.
Farms in the sky, an interview with Dickson Despommier
(10/12/2010) To solve today's environmental crises—climate change, deforestation, mass extinction, and marine degradation—while feeding a growing population (on its way to 9 billion) will require not only thinking outside the box, but a "new box altogether" according to Dr. Dickson Despommier, author of the new book, The Vertical Farm. Exciting policy-makers and environmentalists, Despommier's bold idea for skyscrapers devoted to agriculture is certainly thinking outside the box.
Indonesia is the 3rd largest GHG emitter but reducing deforestation offers big opportunity, says government
(09/28/2010) Indonesia's greenhouse gas emissions reached 2.1 billion tons of carbon dioxide in 2005, making it the world's third largest emitter of greenhouse gases, but offering opportunities to substantially reduce emissions through forest conservation, reduced use of fire, protection of peatlands, and better forest management, reports a series of studies released earlier this month by the country's National Climate Change Council (DNPI).
Nearly half of the world's wetlands used for crops
(09/27/2010) Wetlands used for crops have expanded significantly over the past eighty years. According to a new study in the open-access journal Tropical Conservation Science, wetlands being utilized for crop production has jumped from 25 percent in 1926 to 43 percent in 2006 of the world's wetlands as identified by the Ramsar Convention on Wetlands.
Satellites show mangrove forest loss even worse than estimated
(08/19/2010) New satellite data shows that human actions are wiping out mangrove forests even faster than previous bleak estimates. Conducted by the US Geological Survey and NASA, the researchers found that mangroves comprise 12.3 percent less area than previously estimated. In total, satellites reveal that mangrove forests cover approximately 53,290 square miles (137,760 square kilometers). "Our assessment shows, for the first time, the exact extent and distribution of mangrove forests of the world at 30 meters spatial resolution, the highest resolution ever," said Dr Chandra Giri from USGS.
Could biochar save the world?
(08/16/2010) Biochar—the agricultural application of charcoal produced from burning biomass—may be one of this century's most important social and environmental revolutions. This seemingly humble practice—a technology that goes back thousands of years—has the potential to help mitigate a number of entrenched global problems: desperate hunger, lack of soil fertility in the tropics, rainforest destruction due to slash-and-burn agriculture, and even climate change. "Biochar is a recalcitrant form of carbon that will stay almost entirely unaltered in soils for very long periods of time. So you can sequester carbon in a simple, durable and safe way by putting the char in the soil. Other types of carbon in soils rapidly turn into carbon dioxide. Char doesn't," managing director of the Biochar Fund, Laurens Rademakers, told mongabay.com in a recent interview.
Reforestation of rainforests sequesters more carbon than plantations
(08/03/2010) A new study in Ecological Management & Restoration has found that reforesting rainforest captures more carbon than monoculture plantation and even mixed species plantations. The research tested three projects in north-eastern Australia: a rainforest reforesting project using a variety of native trees, a mixed species plantation, and a monoculture plantation of conifers.
A fifth of the world's mangroves gone in 30 years
(07/18/2010) A new report by the United Nation Environment Program (UNEP) and the Nature Conservancy has found that mangrove forests are being lost at staggering rates worldwide: since 1980 one fifth of the world's mangroves have been felled.
Illegal logging declining worldwide, but still 'major problem'
(07/15/2010) A new report by the Chatham House finds that illegal logging in tropical forest nation is primarily on the decline, providing evidence that new laws and international efforts on the issue are having a positive impact. According to the report, the total global production of illegal timber has fallen by 22 percent since 2002. Yet the report also finds that nations—both producers and consumers—have a long way to go before illegal logging is an issue of the past.
Conservation photography: on shooting and saving the world's largest temperate rainforest, an interview with Amy Gulick
(07/11/2010) Most of the US's large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see have been almost wholly replaced by agriculture and increasing suburbs. Habitats, from deserts to western forests, are largely carved by roads and under heavy impact from resource exploitation to invasive species. Coastal marine systems, once super abundant, have partially collapsed in many places due to overfishing, as well as pollution and development. Despite this, there are still places in the US where the 'wild' in wilderness remains largely true, and one of those is the Tongass temperate rainforest of Southeast Alaska.
Scientists warn that Malaysia is converting tropical forests to rubberwood plantations
(06/24/2010) The Association for Tropical Biology and Conservation (ATBC) has condemned Malaysia's booming practice of converting tropical forests into rubberwood plantations, arguing that the conversion threatens Malaysia's biodiversity, endangered species, and releases significant greenhouse gas emissions.
Rainforest scientists urge UN to correct "serious loophole" by changing its definition of 'forest'
(06/24/2010) The Association for Tropical Biology and Conservation (ATBC) has released a resolution urging the UN to change its definition for 'forest', before the controversial definition undermines conservation efforts, biodiversity preservation, carbon sequestration, and the nascent REDD (Reducing Emissions through Deforestation and forest Degradation).
A total ban on primary forest logging needed to save the world, an interview with activist Glen Barry
(06/02/2010) Radical, controversial, ahead-of-his-time, brilliant, or extremist: call Dr. Glen Barry, the head of Ecological Internet, what you will, but there is no question that his environmental advocacy group has achieved major successes in the past years, even if many of these are below the radar of big conservation groups and mainstream media. "We tend to be a little different than many organizations in that we do take a deep ecology, or biocentric approach," Barry says of the organization he heads. "[Ecological Internet] is very, very concerned about the state of the planet. It is my analysis that we have passed the carrying capacity of the Earth, that in several matters we have crossed different ecosystem tipping points or are near doing so. And we really act with more urgency, and more ecological science, than I think the average campaign organization."
Big compromise reached on Canada's Boreal by environmental groups and forestry industry
(05/19/2010) In what is being heralded as the 'world's largest conservation agreement' 20 Canadian forestry companies and nine environmental organizations have announced an agreement covering 72 million hectares of the Canadian boreal forest (an area bigger than France). Reaching a major compromise, the agreement essentially ends a long battle between several environmental groups and the companies signing on, all members of the Forest Products Association of Canada (FPAC).
World failing on every environmental issue: an op-ed for Earth Day
(04/22/2010) The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the white rhino—from extinction; or preserving an ecological region like the Amazon. That was a different age. Today we speak of preserving world biodiversity, of saving the 'lungs of the planet', of mitigating global climate change. No longer are humans over-reaching in just one region, but we are overreaching the whole planet, stretching ecological systems to a breaking point. While we are aware of the issues that threaten the well-being of life on this planet, including our own, how are we progressing on solutions?
Close to a billion species: ocean exploration reveals shocking diversity of tiny marine life
(04/19/2010) Biologists worldwide may have to start re-evaluating their estimates of the number of species on Earth, since expeditions documenting the oceans' tiniest species have revealed shocking diversity: in the tens of millions of species, at least, and according to one researcher "closer to a billion". Fourteen field projects sent out by the Census of Marine Life focused on the oceans' smallest inhabitants: microbes, zooplankton, and tiny burrowing species inhabiting the deep sea bed. What they found was astounding.
Cochabamba Climate Conference: the Coca Contradiction
(04/11/2010) In the high stakes game of geopolitics, the small and economically disadvantaged Andean nation of Bolivia has little clout. Now, however, the country’s indigenous president Evo Morales wants to establish more of a significant voice on the world stage. Recently, he has turned himself into something of a spokesperson on the issue of climate change. Decrying the failure of world leaders to come to a satisfactory agreement on global warming, he is intent on shaming the Global North into addressing climate change. Whatever Bolivia lacks in terms of political and economic muscle, Morales would like to offset through skilled use of moral persuasion.
16 percent of mangrove species threatened with extinction
(04/11/2010) The first ever assessment of mangrove species by the IUCN Red List found 11 out of 70 mangrove species threatened with extinction, including two which were listed as Critically Endangered. Threats include coastal development, logging, agriculture, and climate change.
Half of Indonesia's mangroves gone in less than thirty years
(03/23/2010) The Jakarta Post reports that, according to the local NGO People’s Coalition for Justice in Fisheries (Kiara), Indonesia's has lost 2.2 million hectares of mangroves in less than thirty years, going from covering 4.2 million hectares in 1982 to just 2 million hectares today.
Scientists: new study does not disprove climate change threat to Amazon
(03/19/2010) Recently, Boston University issued a press release on a scientific study regarding the Amazon's resilience to drought. The press release claimed that the study had debunked the Intergovernmental Panel on Climate Change's (IPCC) theory that climate change could turn approximately 40 percent of the Amazon into savanna due to declining rainfall. The story was picked up both by mass media, environmental news sites (including mongabay.com), and climate deniers' blogs. However, nineteen of the world's top Amazonian experts have issued a written response stating that the press release from Boston University was "misleading and inaccurate".
Amazon confusion: new research shows forest is resilient to drought, but is this the whole picture?
(03/15/2010) A drought that happens once in a hundred years had little negative or positive effect on the Amazon rainforest according to a NASA funded study in Geophysical Research Letters. "We found no big differences in the greenness level of these forests between drought and non-drought years, which suggests that these forests may be more tolerant of droughts than we previously thought," said Arindam Samanta, the study's lead author from Boston University.
Why seed dispersers matter, an interview with Pierre-Michel Forget, chair of the FSD International Symposium
(03/07/2010) There are few areas of research in tropical biology more exciting and more important than seed dispersal. Seed dispersal—the process by which seeds are spread from parent trees to new sprouting ground—underpins the ecology of forests worldwide. In temperate forests, seeds are often spread by wind and water, though sometimes by animals such as squirrels and birds. But in the tropics the emphasis is far heavier on the latter, as Dr. Pierre-Michel Forget explains to mongabay.com. "[In rainforests] a majority of plants, trees, lianas, epiphytes, and herbs, are dispersed by fruit-eating animals. […] As seed size varies from tiny seeds less than one millimetres to several centimetres in length or diameter, then, a variety of animals is required to disperse such a continuum and variety of seed size, the smaller being transported by ants and dung beetles, the larger swallowed by cassowary, tapir and elephant, for instance."
Massive methane leak in Arctic could trigger abrupt warming
(03/04/2010) Methane, a greenhouse gas 30 times more potent than carbon, is spewing from what was believed to be an impermeable barrier in Siberia in amounts equal to methane releases from the world's oceans. The discovery has lead researchers to fear the possibility of abrupt climate warming. According to the study published in Science, subsea permafrost below the East Siberian Arctic Shelf has become compromised, leaking vast amounts of methane into the atmosphere.
Guyana bans gold mining in the 'Land of the Giants'
(03/01/2010) Guyana has banned gold dredging in the Rewa Head region of the South American country after pressure from Amerindian communities in the area. A recent expedition to Rewa Head turned up unspoiled wilderness and mind-boggling biodiversity. The researchers, in just six weeks, stumbled on the world's largest snake (anaconda), spider (the aptly named goliath bird-eating spider), armadillo (the giant armadillo), anteater (the giant anteater), and otter (the giant otter), leading them to dub the area 'the Land of the Giants'. "During our brief survey we had encounters with wildlife that tropical biologists can spend years in the field waiting for. On a single day we had two tapirs paddle alongside our boat, we were swooped on by a crested eagle and then later charged by a group of giant otters."
How that cork in your wine bottle helps forests and biodiversity, an interview with Patrick Spencer
(03/01/2010) Next time you’re in the supermarket looking to buy a nice bottle of wine: think cork. Although it’s not widely known, the cork industry is helping to sustain one of the world’s most biodiverse forests, including a number of endangered species such as the Iberian lynx and the Barbary deer. Spreading across 6.6 million acres in southern Europe (France, Spain, Portugal, and Italy) and northern Africa (Algeria, Morocco, and Tunisia) oak cork trees Quercus suber are actually preserved and protected by the industry.
Rainforest expert agrees with IPCC: warns of 'tipping point' for Amazon
(02/03/2010) Amid questions over the Amazon forests' capacity to survive climate change, a renowned tropical biologist says that in fact the fears are real, reports Tierramerica. Speaking at the Biodiversity Science Policy Conference in Paris, Thomas Lovejoy, biodiversity chair at the Washington DC-based Heinz Center for Science, Economics and the Environment, and chief biodiversity adviser to the president of the World Bank, described the Amazon rainforest as "very close to a tipping point".
Will it be possible to feed nine billion people sustainably?
(01/28/2010) Sometime around 2050 researchers estimate that the global population will level-out at nine billion people, adding over two billion more people to the planet. Since, one billion of the world's population (more than one in seven) are currently going hungry—the largest number in all of history—scientists are struggling with how, not only to feed those who are hungry today, but also the additional two billion that will soon grace our planet. In a new paper in Science researchers make recommendations on how the world may one day feed nine billion people—sustainably.
Photos: park in Ecuador likely contains world’s highest biodiversity, but threatened by oil
(01/19/2010) In the midst of a seesaw political battle to save Yasuni National Park from oil developers, scientists have announced that this park in Ecuador houses more species than anywhere else in South America—and maybe the world. "Yasuní is at the center of a small zone where South America's amphibians, birds, mammals, and vascular plants all reach maximum diversity," Dr. Clinton Jenkins of the University of Maryland said in a press release. "We dubbed this area the 'quadruple richness center.'"
Saving biodiversity 'on the same scale' as climate change: German Chancellor
(01/11/2010) In a kick-off event for the UN's Year of Biodiversity, German Chancellor Angela Merkel, compared the importance of saving biodiversity to stopping climate change.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Underwater rocks could be used for massive carbon storage on America's East Coast
(01/05/2010) Considering it is unlikely that global carbon emissions will start dropping anytime soon, researchers are beginning to look at other methods to combat climate change. One of these is to hook polluting power plants up to massive carbon sinks where instead of the carbon going into the atmosphere it would be stored away in rocks. The process is known as carbon capture and storage or CCS. But before one can even debate the pros and cons of setting up CCS, scientists must see if high-quality sites exist.
More than half world's science academies support call to save rainforests
(12/17/2009) More than half world's science academies have signed a statement supporting a plan to save tropical forests as a means to fight climate change, reports the Global Canopy Program, an initiative that has worked closely with Prince Charles to promote rainforest conservation. The statement argues that tropical forest protection is a critical strategy for reducing greenhouse gas emissions over the next 15-20 years. It calls upon world leaders to reach a consensus on a path forward for a funding package that would support the infrastructure needed to develop an effective reducing emissions from deforestation and degradation (REDD) mechanism.
Unilever suspends palm oil contract after supplier found to be destroying rainforests
(12/12/2009) The world's largest user of palm oil, Unilever, has suspended its $32.6 million contract with the Indonesian group Sinar Mas after an independent audit proved that Sinar Mas is involved in the destruction of rainforest, reports Reuters. The audit was conducted early this year after a report by Greenpeace alleged that Sinar Mas was engaged in deforestation and the draining of peatlands, both of which release significant amounts of greenhouse gases into the atmosphere. Deforestation across Indonesia and Malaysia, in part for oil palm plantations, has also added pressure on many many endangered species, including orangutans, tigers, elephants, and rhinos.
REDD may miss up to 80 percent of land use change emissions
(12/11/2009) The political definition of 'forest' used in REDD (Reduce Emissions from Deforestation and forest Degradation) threatens to undermine the program's objective to conserve ecosystems for their ability to sequester carbon, according to a new analysis by the Alternatives to Slash and Burn (ASB) Partnership for Tropical Forest Margins. In an analysis of three Indonesian provinces using REDD proposals for carbon accounting, ASB found that REDD may miss up to 80 percent of the actual emissions due to land use change. The carbon accounting problems could be fixed, according to ASB, by expanding REDD's purpose from reducing emissions linked to deforestation (considering the problematic definition of forests) to reducing emission from all land use changes that either release or capture greenhouse gases, including but not limited to forests.
Developed countries plan to hide emissions from logging
(12/09/2009) While developing countries in the tropics have received a lot of attention for their deforestation emissions (one thinks of Brazil, Indonesia, and Malaysia), emissions from logging—considered forest cover change—in wealthy northern countries has been largely overlooked by the media. It seems industrialized countries prefer it this way: a new study reveals just how these countries are planning to hide forestry-related emissions, allowing nations such as Canada, Russia, and the EU to contribute to climate change without penalty.
REDD in Madagascar
(12/08/2009) Despite damage from ongoing illegal logging, Madagascar's remaining forests are poised to benefit from the proposed REDD mechanism, a U.N.-backed scheme that would compensate tropical developing countries for reducing emissions from deforestation and degradation, reports a new paper that analyzes efforts to use carbon finance to protect the Indian Ocean island's remaining forests. The research is published in the open-access Madagascar Conservation & Development.
Indonesia: Kalimantan's Lowland Peat Forests Explained
(12/04/2009) Earth's tropical rainforests are a critical component of the world's carbon cycle yet cover only about 12% of its terrestrial land. Accounting for 40% of the world's terrestrial carbon and 50% of the world's gross primary productivity,. the production of organic compounds primarily through photosynthesis, tropical rainforests also are one of the engines driving Earth's atmospheric circulation patterns.
Brazil to push for 10% limit on REDD carbon offsets
(12/02/2009) Brazil will propose limiting the amount of carbon an industrialized country can offset via a proposed forest conservation initiative to ten percent of their emissions, reports Bloomberg.
Reforestation effort would lower Britain's greenhouse gas emissions by 10 percent
(11/25/2009) A study by Britain's Forestry Commission found that planting 23,000 hectares of forest every year for the next 40 years would lower the island nation's greenhouse gas emissions by 10 percent, according to reporting by the BBC.
Reforestation: Challenges and Opportunities
(11/23/2009) Deforestation in the Brazilian Amazon is a timeless issue that has been propounded into the public knowledge sphere since I was a child. Always eager to learn the actuality of environmental propaganda, I have been tracking reforestation practices since 2001. I first ground-truthed the realities of sustainable development in Costa Rica the summer after my freshman year at Vassar. We visited various national parks throughout the country and had the opportunity to conduct interviews with locals surrounding Monteverde on the impacts of ecotourism. This program was conducted through the School for Field Studies. My impressions were of surprise and delight at how eco-conscious Ticos appeared to be.
Oceans' ability to sequester carbon diminishing
(11/18/2009) A new study—the first of its kind—has completed an annual accounting of the oceans' intake of carbon over the past 250 years, and the news is troubling. According to the study, published in Nature, the oceans' ability to sequester carbon is struggling to keep-up with mankind's ever-growing emissions. Since 2000 researchers estimate that while every year the oceans continue to sequester more anthropogenic carbon emission, the overall proportion of carbon taken in by the oceans is declining.
Record year for CO2 emissions, even with economic slowdown
(11/17/2009) 8.7 billion tons of carbon dioxide was emitted into the earth's atmosphere in 2008, a growth of 2 percent despite the economic crisis. This averages out to each person contributing a record high of 1.3 tons of carbon, according to a report in the journal Nature Science. While the global recession slowed the growth of fossil fuel emissions for the first time this decade, it did not lower emissions altogether.
Coastal habitats may sequester 50 times more carbon than tropical forests by area
(11/16/2009) Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marhses—sequester as much as 50 times the amount of carbon in their soil per hectare as tropical forest. "The key difference between these coastal habitats and forests is that mangroves, seagrasses and the plants in salt marshes are extremely efficient at burying carbon in the sediment below them where it can stay for centuries or even millennia."
New report: boreal forests contain more carbon than tropical forest per hectare
(11/12/2009) A new report states that boreal forests store nearly twice as much carbon as tropical forests per hectare: a fact which researchers say should make the conservation of boreal forests as important as tropical in climate change negotiations. The report from the Canadian Boreal Initiative and the Boreal Songbird Initiative, entitled "The Carbon the World Forgot", estimates that the boreal forest—which survives in massive swathes across Alaska, Canada, Northern Europe, and Russia—stores 22 percent of all carbon on the earth's land surface. According to the study the boreal contains 703 gigatons of carbon, while the world's tropical forests contain 375 gigatons.
Declaration calls for more wilderness protected areas to combat global warming
(11/11/2009) Meeting this week in Merida, Mexico, the 9th World Wilderness Congress (WILD9) has released a declaration that calls for increasing wilderness protections in an effort to mitigate climate change. The declaration, which is signed by a number of influential organizations, argues that wilderness areas—both terrestrial and marine—act as carbon sinks, while preserving biodiversity and vital ecosystem services.
