World Bank offers $300M for forest conservation, emissions reductions
(10/15/2007) Tropical forest countries will be eligible for payments for preventing deforestation under a program unveiled last week by the World Bank.


Forests reduce flooding
(10/4/2007) While conventional wisdom holds that forests help buffer against catastrophic flooding, there has been little evidence to support such notions. A 2005 report by the Food and Agricultural Organization of the United Nations (FAO) and the Center for International Forestry Research (CIFOR) cited this lack of evidence and argued that flood mitigation efforts though forest preservation could not be justified on economic grounds. Now, a new study, published in the journal Global Change Biology, suggests that forests do impact the occurrence and severity of destructive flooding. A prominent researcher is already calling the new work a "landmark study" in support of forest conservation.


Carbon for forests will help Aceh recover from war, tsunami
(9/18/2007) Carbon credits through forest conservation will play an important role in Aceh's recovery from decades of civil war and the devastating 2004 tsunami, which left more than 167,000 people dead and 500,000 homeless in the Indonesia province, said Aceh governor Irwandi Jusuf in meeting in San Francisco.


Do Costa Rica's payments for environmental services work?
(9/17/2007) While Costa Rica is now known as a world leader for conservation policies and ecotourism, the Central American country had some of the world's highest deforestation rates prior to establishing its reputation. Clearing for cattle pasture and agriculture destroyed much of the country's biodiverse rainforests in the 1960s and 1970s.


Is peat swamp worth more than palm oil plantations?
(7/16/2007) Could peat swamp be worth more intact for their carbon value than palm oil plantations for their oil? Quick analysis suggests yes, though binding limits on emissions will be needed to trigger the largest ever flow of money from the industrialized world to developing countries. At stake: the bulk of the world's biodiversity.


Indonesia's peat swamps worth $39B/year
(7/11/2007) Indonesia's peat swamps are worth $39 billion in carbon credits per year, according to rough calculations by Bloomberg.


Mangroves more threatened than rainforests
(7/5/2007) Destruction of mangrove forests could leave the world deprived of their important ecological services by the end of a century, warns an international team of scientists writing in the July 6th issue of the journal Science.


First U.S. test of ecological services payment underway
(6/27/2007) Farmers in Jamestown, R.I., are being paid by local residents to delay haying their fields until after birds have completed nesting in a unique test to establish investment markets for ecological services.


Can cattle ranchers and soy farmers save the Amazon?
(6/6/2007) John Cain Carter, a Texas rancher who moved to the heart of the Amazon 11 years ago and founded what is perhaps the most innovative organization working in the Amazon, Alianca da Terra, believes the only way to save the Amazon is through the market. Carter says that by giving producers incentives to reduce their impact on the forest, the market can succeed where conservation efforts have failed. What is most remarkable about Alianca's system is that it has the potential to be applied to any commodity anywhere in the world. That means palm oil in Borneo could be certified just as easily as sugar cane in Brazil or sheep in New Zealand. By addressing the supply chain, tracing agricultural products back to the specific fields where they were produced, the system offers perhaps the best market-based solution to combating deforestation. Combining these approaches with large-scale land conservation and scientific research offers what may be the best hope for saving the Amazon.


Globalization could save the Amazon rainforest
(6/3/2007) The Amazon basin is home to the world's largest rainforest, an ecosystem that supports perhaps 30 percent of the world's terrestrial species, stores vast amounts of carbon, and exerts considerable influence on global weather patterns and climate. Few would dispute that it is one of the planet's most important landscapes. Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change. Few people understand these impacts better than Dr. Daniel Nepstad, one of the world's foremost experts on the Amazon rainforest. Now head of the Woods Hole Research Center's Amazon program in Belem, Brazil, Nepstad has spent more than 23 years in the Amazon, studying subjects ranging from forest fires and forest management policy to sustainable development. Nepstad says the Amazon is presently at a point unlike any he's ever seen, one where there are unparalleled risks and opportunities. While he's hopeful about some of the trends, he knows the Amazon faces difficult and immediate challenges.


Indonesia could earn $100-$180 million from carbon trading
(5/28/2007) Indonesia says it hopes to soon see millions of dollars from carbon trading, reports the International Tropical Timber Organization (ITTO) in its latest update.


20-40% of U.S. bees have disappeared
(5/14/2007) Known and unknown ailments have killed 20 to 40 percent of bee colonies across the United States this winter according to a leading entomologist.


Amazon rainforest locks up 11 years of CO2 emissions
(5/8/2007) The amount and distribution of above ground biomass (or the amount of carbon contained in vegetation) in the Amazon basin is largely unknown, making it difficult to estimate how much carbon dioxide is produced through deforestation and how much is sequestered through forest regrowth. To address this uncertainty, a team of scientists from Caltech, the Woods Hole Institute, and INPE (Brazil's space agency), have developed a new method to determine forest biomass using remote sensing and field plot measurements. The researchers say the work will help them better understand the role of Amazon rainforest in global climate change.


Ecosystems are capital assets argues report
(5/7/2007) Global ecosystems should be treated as capital assets argues a new report released today by the World Resources Institute (WRI). The new WRI report examines trends revealed in the 2005 Millennium Ecosystem Assessment (MA) by the U.N. and puts forth an agenda for business, governments, and civil society to reverse ecosystem degradation.


Farming in the rainforest can preserve biodiversity, ecological services
(3/5/2007) While conversion of tropical forest for agriculture results in significant declines in biodiversity and carbon storage, an analysis of Indonesian rainforests shows that farming cacao under the partial shade of high canopy trees can provide a way to balance economic gain with environmental considerations.


Amazon deforestation damaging critical ecosystem services
(2/8/2007) Human disturbance of the Amazon rainforest is more extensive than previously thought say a team of scientists writing in the current edition of the journal Frontiers in Ecology. Reviewing recent research on the Amazon ecosystem, they note that human activities are affecting the health of the forest and impacting the ecological goods and services the Amazon provides mankind.


Animal pollinators responsible for 35 percent of world food crop
(10/25/2006) A new study calculates that 35 percent of the world's crop production is dependent on pollinators, like bats, bees, and birds. The research suggests that biodiversity loss could directly impact global food crops.


Biodiversity extinction crisis will disrupt important ecological services warns study
(10/25/2006) Loss of biodiversity will have an ecologically-costly impact according to a study published in the journal Nature this week. The new study, headed by a biologist at the University of California, Santa Barbara (UCSB), found that species extinction will reduce nature's ability to maintain ecological balance and "services" such as water filtration, nutrient cycling, and pollination.


Global Warming Threatens Pollination Timing
(8/9/2006) In addition to the more obvious effects of climate change, such as rising sea levels and increasing storm activity, there is the potential to dramatically alter ecological communities. Dr. David Inouye, director of University of Maryland's graduate program in Sustainable Development and conservation Biology, reports that global warming could disrupt the timing of pollination in alpine environments, with serious negative impacts to both plants and pollinators.


Bees and flowers disappearing together
(7/23/2006) The diversity of bees and of the flowers they pollinate, has declined significantly in Britain and the Netherlands over the last 25 years according to research led by the University of Leeds and published in Science this Friday (21 July 2006). The paper is the first evidence of a widespread decline in bee diversity.


Insects worth $57 billion to US economy
(4/1/2006) A new study says insects are worth at least $57 billion to the American economy. In the April 2006 issue of BioScience, John E. Losey of Cornell University and Mace Vaughan of the Xerces Society for Invertebrate conservation estimate the value of ecological services provided by insects. Looking at just four services--dung burial, control of crop pests, pollination, and wildlife nutrition--Losey and Vaughan calculate that the annual value of insects in these roles is at least $57 billion in the United States.


Coral reefs and mangroves have high economic value
(1/24/2006) Protecting coral reefs and mangrove forests makes economic sense according to a new report by the United Nations Environment Programme (UNEP). The report argues that conserving these ecosystems for the services they provide--from fisheries protection to erosion control to a source for medical compounds--is cost-effective relative to destroying them and substituting their role with man-made structures.


Deforestation causes 25% of greenhouse gas emissions
(12/10/2005) Yesterday the Food and Agriculture Organization of the United Nations (FAO) offered to provide forestry data and technical assistance to countries looking to mitigate greenhouse gas emissions through the reduction of forest loss.


Rainforest conservation worth the cost shows new study
(11/2/2005) The economic benefits of protecting a rainforest reserve outweigh the costs of preserving it, says University of Alberta research--the first of its kind to have conducted a cost-benefit analysis on the conservation of species diversity. "The traditional moral and aesthetic arguments have been made about why we should conserve the biodiversity in rainforests, but little has been done that looks at whether it makes pure economic sense to do so," said Dr. Robin Naidoo, who did his PhD at the U of A in biological sciences and rural economy. "We provide some good evidence from a strict economic side, that yes, it does."


Deforestation and erosion starving Malawi
(10/13/2005) Forest loss and erosion could doom Malawi to perpetual food shortages as the country's fertile soil is literally swept down to its rivers and flushed out to sea.


Cultivated forests play important economic and ecological role in Indonesia
(5/17/2005) Old growth tropical forests are valuable and irreplaceable ecosystems that house the majority of Earth's known terrestrial biological diversity. While these forests are rapidly disappearing, they are not necessarily being completely cleared without replacement. In some regions, primary forests are being replaced with "cultivated forests" or "forest gardens," where useful trees are planted on farmlands after the removal of pre-existing natural forests. A new report Domesticating forests: How farmers manage forest resources by Genevieve Michon explores the characteristics and implications of these forests in Indonesia.


For What It's Worth: Ecological Services and conservation
(5/4/2005) For a long time, preserving natural spaces was considered to be a favor to the environment without a true, measurable benefit to businesses, industrial production and productivity. In recent years however, scientists are increasingly producing substantial evidence to support the notion that the natural environment supplies a diverse range of renewable economic benefits beyond timber and fish. These benefits are termed “ecological services” and provide such valuable functions as water treatment, pollination and sediment capture, simply by remaining intact.


Impact of Deforestation - Soil Erosion
(3/1/2005) The loss of trees, which anchor the soil with their roots, causes widespread erosion throughout the tropics. Only a minority of areas have good soils, which after clearing are quickly washed away by the heavy rains. Thus crop yields decline and the people must spend income to import foreign fertilizers or clear additional forest. Costa Rica loses about 860 million tons of valuable topsoil every year, while the Great Red Island, Madagascar, loses so much soil to erosion (400 tons/ha) that its rivers run blood-red, staining the surrounding Indian Ocean. Astronauts have remarked that it looks like Madagascar is bleeding to death, an apt description of a country with grave environmental degradation and an ever-declining agricultural economy that depends on its soils. The rate of increase for soil loss after forest clearing is astonishing; a study in Ivory Coast (Cote d'Ivoire) found that forested slope areas lost 0.03 tons of soil per year per hectare; cultivated slopes annually lost 90 tons per hectare, while bare slopes lost 138 tons per hectare.


Impact of Deforestation - Local and National Effects
(3/1/2005) The local level is where deforestation has the most immediate effect. With forest loss, the local community loses the system that performed valuable but often underappreciated services like ensuring the regular flow of clean water and protecting the community from flood and drought. The forest acts as a sort of sponge, soaking up rainfall brought by tropical storms while anchoring soils and releasing water at regular intervals. This regulating feature of tropical rainforests can help moderate destructive flood and drought cycles that can occur when forests are cleared.


Saving the Rain Forest with Secondary Forest Products
(3/1/2005) There is great potential for the development of secondary forest products on a large scale to contribute to local and national income through the global market. Some forest products can be domesticated and cultivated on a widespread basis on highly degraded and formerly forested lands. Many of these products are better suited to the tropical environment and produce greater economic returns at less fiscal and environmental costs.
