(06/29/2009) Often we hear about endangered species—animals or plants on the edge of extinction—however we rarely hear about endangered environments—entire ecosystems that may disappear from Earth due to humankind’s growing footprint. Tropical dry forests are just such an ecosystem: with only 2 percent of the world’s tropical dry forest remaining it is one of the world’s most endangered ecosystems. A newly established organization, the Azuero Earth Project, is working not only to preserve some of the world’s last tropical dry forest on the Azuero peninsula in Panama, but also to begin restoration projects hoping to aid both the forest’s viability and the local people. Edwina von Gal, a landscape designer, is one of the founders of the Azuero Earth Project, as well as president of the organization.
(06/25/2009) Between 1700 and 1850 forest cover in India and China plummeted, falling from 40-50 percent of land area to 5-10 percent. Forests were cut for agricultural use across Southeast Asia to feed a growing population, but the changes from forests to crops had unforeseen consequences. A new study published in the Proceedings of the National Academy of Sciences links this deforestation across Southeast Asia with changes in the Asian Monsoon, including significantly decreased rainfall.
(06/24/2009) Gum trees dot the hills and valleys of south-eastern Australia, a vivid fixture of the rolling landscape. But despite the seeming health of these iconic trees, they have earned the morbid nickname "the living dead" among ecologists, who say natural changes and human actions are threatening the next generation of gum trees. The gum trees that are scattered through the landscape are naturally dying off at a rate of one to two percent each year. With no replacement, researchers fear more than 100,000 square kilometers of land could be virtually treeless within the next 100 years.
(06/18/2009) While the use of synthetic fertilizer has greatly increased agricultural production globally—helping to feed a global population that is not slowing down—it has brought with it high environmental costs. Fertilizer runoff has polluted many coastal regions creating ‘dead zones’ where the ocean is starved of oxygen by the influx of nitrogen. Synthetic fertilizers have also polluted the air with ammonia, and sent emissions of nitrous oxide into the atmosphere, contributing to global warming.
(06/17/2009) Government officials and scientists released a 196 page report detailing the impact of global warming on the U.S. yesterday. The study, commissioned in 2007 during the Bush Administration, found that every region of the U.S. faces large-scale consequences due to climate change, including higher temperatures, increased droughts, heavier rainfall, more severe weather, water shortages, rising sea levels, ecosystem stresses, loss of biodiversity, and economic impacts.
(06/02/2009) Tropical East Asia's rapid population growth and dramatic economic expansion over the past half century have taken a heavy toll on its natural resources. More than two-thirds of the region's original forest cover has been cleared or converted for agriculture and plantations, while its flora and fauna have suffered dearly from a burgeoning trade in wildlife products—several charismatic species have gone extinct as a direct consequence of human exploitation. Nevertheless tropical East Asia remains a top global priority for conservation, supporting up to a quarter of the world's terrestrial species.
(06/01/2009) Major international companies are unwittingly driving the deforestation of the Amazon rainforest through their purchases of leather, beef and other products supplied from the Brazil cattle industry, alleges a new report from Greenpeace. The report, Slaughtering the Amazon, is based on a three-year undercover investigation of the Brazilian cattle industry, which accounts for 80 percent of Amazon deforestation and roughly 14 percent of the world's annual forest loss. Greenpeace found that Brazilian beef companies are important suppliers of raw materials used by leading global brands, including Adidas/Reebok, Nike, Carrefour, Eurostar, Unilever, Johnson & Johnson, Toyota, Honda, Gucci, Louis Vuitton, Prada, IKEA, Kraft, Tesco and Wal-Mart, among others.
(05/31/2009) More than 100,000 hectares of Brazil's most threatened ecosystem was cleared between 2005 and 2008, reports a study by the Fundação SOS Mata Atlãntica and the National Institute for Space Research (INPE). The "Atlas of Mata Atlântica Remnants", released May 26, assessed the extent of the Mata Atlântica (Atlantic Forest) across 10 of the 17 states where the coastal rainforest occurs. It found that an 102,938 hectares were destroyed during the three year period. The annual loss of 34,121 hectares per year was 2.4 percent lower than the 34,965 ha recorded from the 2000-2005 period.
(05/26/2009) Over two-and-half million hectares in the Democratic Republic of the Congo; half a million hectares in Tanzania; and a quarter of a million hectares in Libya: these figures represent just some of the recent international land deals where wealthy countries buy up land in poorer nations for food, and sometimes biofuel, production. The controversial trend has sparked a recent report from the International Food Policy Research Institute (IFPRI) highlighting what nations have to gain—and lose—from participating in such deals.
(05/25/2009) A partnership between local villages and conservation groups, headed up by the Bonobo Conservation Initiative (BCI), has led to the creation of a new 1,847 square mile (4,875 square kilometer) reserve in the Democratic Republic of Congo (DRC). The reserve will save some of the region’s last pristine forests: ensuring the survival of the embattled bonobo—the least-known of the world’s four great ape species—and protecting a wide variety of biodiversity from the Congo peacock to the dwarf crocodile. However, the Kokolopori Bonobo Reserve is worth attention for another reason: every step of its creation—from biological surveys to reserve management—has been run by the local Congolese NGO and villages of Kokolopori.
(05/20/2009) Asia Pulp & Paper and Sinar Mas Group have acquired a license to clear hundreds of hectares of unprotected rainforest near Bukit Tigapuluh National Park on the Indonesian island of Sumatra, report environmental groups who say the activity threatens a population of critically endangered orangutans that have been re-introduced into the wild. The companies intend to log the concession for timber and plant it for industrial timber and oil palm plantations.
(05/19/2009) An initiative using soil carbon enrichment techniques to boost agricultural yields, alleviate poverty, and protect endangered forests in Central Africa was today selected as one of six projects to win funding under the Congo Basin Forest Fund (CBFF). The scientific committee of the CBFF awarded Belgium's Biochar Fund and its Congolese partner ADAPEL €300,000 to implement its biochar concept in 10 villages in the Equateur Province of the Democratic Republic of Congo. The approach improves the fertility of soils through the introduction of "biochar" — charcoal produced from the burning of agricultural residues and waste biomass under reduced oxygen conditions — thereby increasing crop yields and reducing the need to clear forest for slash-and-burn agriculture.
(05/07/2009) Yesterday the Obama Administration established a Biofuels Interagency Working Group to oversee implementation of new rules and research regarding biofuels. On the group’s first day of work they would do well to look at a new study in Science Magazine comparing the efficacy of ethanol versus bioelectricity.
(04/28/2009) By the end of the century nations in Southeast Asia will face debilitating economic loss due to global warming, according to a new study from the Asian Development Bank. Analyzing Indonesia, Philippines, Thailand, and Vietnam the study found that they could suffer an annual loss of 6.7 percent ($230 billion dollars) in combined gross domestic product by 2100, more than double the global average which is estimated at a loss of 2.6 percent.
(04/21/2009) In Masai Mara, one of Africa’s most treasured parks, researchers have found significant, in some cases catastrophic, declines of wild grazing animals. In fifteen years six of seven hoofed animals—giraffes, warthogs, hartebeest, impala, topis and waterbucks—showed declines. The study published in the British Journal of Zoology confirms what has long been expected: wildlife populations in Masai Mara are plummeting due to increased competition with humans and livestock.
(04/15/2009) Brazil could triple its agricultural without the needing to clear additional rainforest in the Amazon Basin, Roberto Mangabeira Unger, Brazil's Minister of Strategic Affairs, told Bloomberg in an interview. The argument that Brazil can expand its agricultural production without harming the Amazon is a mantra among Brazilian officials. The country has vast tracts of pasture and agricultural land that are being underutilized or have been abandoned, but rapidly appreciating land prices, coupled with poor governance and inconsistent enforcement of environmental laws, means that it is often more profitable to clear new forest land than to rehabilitate pasture.
(04/15/2009) In 1999 a super cyclone struck the eastern coast of India, leaving 10,000 people dead. At the time the Orissa cyclone, named after the Indian state which it battered, was the deadliest storm in India in over a quarter century. However, according to a new study published in The Proceedings of the National Academy of Sciences the death toll would have been significantly higher if the mangrove forests buffeting the Indian villagers from the sea had not softened the cyclone’s blow.
(04/15/2009) An industry-led moratorium on soy plantings on recently deforested rainforest land continues to show success in the Brazilian Amazon, reports a study released Tuesday by environmental groups and Abiove, the soy industry group that formed the initiative and represents about 90 percent of Brazil's soy crush. The satellite-based study showed that only 12 of 630 sample areas (1,389 of 157,896 hectares) deforested since July 2006 — the date the moratorium took effect — were planted with soy.
(04/01/2009) As concern for the preservation of forest eco-systems in the tropics has increased over past decades, there has been a growing consideration for ways to harmonize tropical agricultural production with the surrounding environment. The idea of shade grown products, especially coffee and cacao, have become the focus of scientific study and of marketable interest for environmentally conscientious consumers. However, the practical and dependable nature of the practice of shade growing for farmers and conservation objectives is still the matter of some debate.
(03/30/2009) Reducing emissions from deforestation and degradation (REDD) is increasingly seen as a compelling way to conserve tropical forests while simultaneously helping mitigate climate change, preserving biodiversity, and providing sustainable livelihoods for rural people. But to become a reality REDD still faces a number of challenges, not least of which is economic competition from other forms of land use. In Indonesia and Malaysia, the biggest competitor is likely oil palm, which is presently one of the most profitable forms of land use. Oil palm is also spreading to other tropical forest areas including the Brazilian Amazon.
(03/23/2009) Already a significant driver of tropical forest conversion across southeast Asia, oil palm expansion could emerge as threat to the Amazon rainforest due to a proposed change in Brazil's forest law, new infrastructure, and the influence of foreign companies in the region, according to researchers writing in the open-access journal Tropical Conservation Science. William F. Laurance, a senior scientist at the Smithsonian Tropical Research Institute (STRI) in Panama City, Panama, and Rhett A. Butler, founder of environmental science web site Mongabay.com, warn that oil palm expansion in the Brazilian Amazon is likely to occur at the expense of natural forest as a result of a proposed revision to the forest code which requires land owners to retain 80 percent forest on lands in the Amazon. The new law would allow up to 30 percent of this reserve to consist of oil palm.
(03/23/2009) Agriculture has long been dependent on the ability of plant species to adapt to varying environmental conditions — without this diversity agriculture development would not have been possible. But human activities are putting this diversity at risk through habitat destruction and introduction of alien species, especially in parts of the world where such diversity is particularly critical: tropical developing countries. This threat has spurred increased efforts to find and conserve plants with special traits adapted to the marginal farming systems of tropical smallholders.
(02/15/2009) More than half of cropland expansion between 1980 and 2000 occurred at the expense of natural forests, while another 30 percent of occurred in disturbed forests, reported a Stanford University researcher presenting Saturday at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago.
(02/05/2009) Embracing more sustainable farming methods is the only way for the world's farmers to grow enough food to meet the demands of a growing population and respond to climate change, the top crop expert with the United Nations Food and Agriculture Organization (FAO) said today.
(02/02/2009) Chocolate, produced from cacao beans, has been a part of American culture for a thousand years according to new paper published in the Proceedings of the National Academy of Sciences. Analyzing chemical residue from jars of native peoples in New Mexico, researchers Patricia Crown and Jeffrey Hurst discovered theobromine, a chemical signature of cacao. The jars have been dated from 1000 to 1125 AD, well over three hundred years before Columbus and the earliest recorded discovery of cacao north of Mexico. The cacao jars are from Pueblo Bonito, an archaeological site in Chaco Canyon, which is located in northwestern New Mexico. Chaco Canyon, once home to 2,000-5,000 inhabitants, was composed of a dense group of pueblos, of which Bonito was the largest. Incorporating 800 rooms, Pueblo Bonito was the center of a number of towns and villages in Chaco Canyon.
(01/29/2009) Nearly 80 percent of land deforested in the Amazon from 1996-2006 is now used for cattle pasture, according to new maps released today in a report by Greenpeace at the World Social Forum in Belem, Brazil. The report, Amazon Cattle Footprint: Mato Grosso: State of Destruction, confirms that cattle ranching is the primary driver of deforestation in Earth's largest rainforest: the Brazilian Amazon.
(01/19/2009) “I want to convince you we need to go beyond primary forests to preserve biodiversity”, Robin Chazdon told an audience at the National Natural History Museum during a symposium on the tropics. Chazdon, a professor of ecology and evolutionary biology at the University of Connecticut, has been studying secondary growth forests for over eighteen years. Secondary forests are those forests in the process of regrowth after being used for agriculture or logging. In her study area of NE Costa Rica, many of these forests were converted to pastures in the 1970s and 1980s, but have since been abandoned. In her presentation Chazdon argued that to preserve biodiversity numerous types of human-impacted landscapes, such as secondary forest, require attention by the conservation community.
(01/13/2009) New satellite research presented for the first time at a symposium entitled “Will the rainforests survive?” showed that selective logging is impacting over a quarter of the world’s rainforests. Gregory Asner from the Carnegie Institution presented the “first true global estimate of selective logging” which showed that 5.5 million square kilometers of the rainforest has already seen selective logging or is slated to be logged in the near future.
(12/23/2008) A new study finds that shade-grown coffee protects the biodiversity of tree species, as well as those of birds and bats. Published in Current Biology, the study found that native trees in shade-grown coffee plantations aid the overall species’ gene flow and can become a focal point for reforestation.
(12/17/2008) The growing concerns about climate change have brought biochar, a charcoal produced from biomass combustion, into limelight. Biochar is a carbon-rich, fine-grained residue which can be produced either by ancient techniques (such as covering burning biomass with soil and allowing it to smolder) or state-of-the-art modern pyrolysis processes. Combustion and decomposition of woody biomass and agricultural residues results in the emission of a large amount of carbon dioxide. Biochar can store this CO2 in the soil leading to reduction in GHGs emission and enhancement of soil fertility. Biochar holds the promise to tackle chronic human development issues like hunger and food insecurity, low agricultural productivity and soil depletion, deforestation and biodiversity loss, energy poverty, air pollution and climate change. Thus, biochar could make a difference in the energy-starved countries of Asia, Africa and Latin America as well as the industrialized world with its vast array of benefits.
