(03/06/2007) Port development and land speculation in Panama is turning some of the Caribbean's most productive mangrove forests into landfill. The landfill would be used for container storage near the city of Colon, at the mouth of the Panama Canal. But local scientists say the transformation could have unintended environmental consequences.
(02/28/2007) Humans are among the most successful of Earth's organisms. Living in every habitable, and sometimes uninhabitable, space, humans dominate the planet's surface and have become a global force that alters natural ecosystems, species distribution, and climate. Virtually no wilderness areas have escaped man's influence. While past conservation efforts have focused on preserving "pristine" wilderness, it is increasingly apparent that few such areas exist. Recognizing this, present conservation efforts are increasingly looking at how human use fits into protected areas management. A new paper published in Biodiversity conservation traces this shift in conservation philosophy since the 19th century. Reviewing the history of four main conservation approaches, Michelle Kalamandeen, a biologist at the University of Guyana, and Lindsey Gillson, a botanist at the University of Cape Town, conclude that current conservation efforts are integrating elements of each philosophy, resulting in a new conservation ethic that uses alternative criteria for designating and managing protected areas, and recognizes the importance of man's influence in wilderness areas.
(02/21/2007) With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.
(02/18/2007) The recent history of Myanmar is rather grim. After gaining independence from the British in 1948, the country suffered a series of military takeovers, and has basically been under the dictatorship of a military junta for the past 50 years. At several points during this time, the people have taken to the streets to peacefully protest the military regime. The last major fight for democracy occurred in 1988, and climaxed with the first democratically held election since independence. The National League for Democracy (NLD), spearheaded by the charismatic Aung San Suu Kyi, won by an overwhelming 84% of the vote. Sadly, regardless of their promises, the military junta had no intention of relinquishing their power, and imprisoned the major leaders of the NLD.
(02/08/2007) 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.
(02/07/2007) The lemurs of Madagascar are among the world's most threatened primates. Extensive habitat destruction, hunting, and the introduction of alien species have doomed dozens of species to extinction since humans first arrived on the island within the past 2000 years. Most of the casualties were Madagascar's largest lemurs -- today the biggest lemur is but a fraction of the gorilla-sized giants that once ruled the island. Despite this relative impoverishment of megafauna, Madagascar still boasts nearly 90 kinds of lemurs, all of which are unique to the island (save one species that was probably introduced to some nearby islands). Lemurs display a range of unusual behvaiors from singing like a whale (the indri) to sashaying across the sand like a ballet dancer (the sifaka). Interest in lemurs has helped Madagascar become a global conservation priority, though they are still at risk. Continued deforestation, scattered hunting, and looming climate change all pose significant threats to some lemur populations. One largely unexamined threat comes from introduced species such as the Indian civet and mongoose, but especially dogs and cats that have become feral.
(02/06/2007) In recent years, scientists have warned of a looming biodiversity extinction crisis, one that will rival or exceed the five historic mass extinctions that occurred millions of years ago. Unlike these past extinctions, which were variously the result of catastrophic climate change, extraterrestrial collisions, atmospheric poisoning, and hyperactive volcanism, the current extinction event is one of our own making, fueled mainly by habitat destruction and, to a lesser extent, over-exploitation of certain species. While few scientists doubt species extinction is occurring, the degree to which it will occur in the future has long been subject of debate in conservation literature. Looking solely at species loss resulting from tropical deforestation, some researchers have forecast extinction rates as high as 75 percent. Now a new paper, published in Biotropica, argues that the most dire of these projections may be overstated. Using models that show lower rates of forest loss based on slowing population growth and other factors, Joseph Wright from the Smithsonian Tropical Research Institute in Panama and Helene Muller-Landau from the University of Minnesota say that species loss may be more moderate than the commonly cited figures. While some scientists have criticized their work as "overly optimistic," prominent biologists say that their research has ignited an important discussion and raises fundamental questions about future conservation priorities and research efforts. This could ultimately result in more effective strategies for conserving biological diversity, they say.
(02/01/2007) An estimated thirty-five million Americans fly fish. George Black is one of them. Black, based in New York City, has written two books on the subject: Casting a Spell: The Bamboo Fly Rod and the American Pursuit of Perfection and The Trout Pool Paradox: The American Lives of Three Rivers. He has also written for the New York Times, the Los Angeles Times, and a number of other publications as well as authoring three books on foreign affairs.
(01/29/2007) Increasing rates of tropical deforestation in the 1970s and 1980s helped trigger the rise of several forest activist groups specifically interested in rainforests. Among the earliest of these organizations was the Rainforest Action Network (RAN). Founded in 1985 by Randall Hayes, RAN lead its first direct campaign in 1987 against Burger King, which at the time was using beef raised on deforested lands in Central America. In response to the nationwide boycott, which caused sales to drop 12%, Burger King canceled $35 million worth of beef contracts from the region and announced they would no longer import beef from the rainforest. Hailed as a major victory for rainforest protection, RAN initiated consumer boycotts of other firms engaged in destructive practices, eventually developing an effective strategy for promoting change at the corporate level. Today San Francisco-based RAN has expanded well beyond its original mission of protecting rainforests. Recently dubbed "the most savvy environmental agitators in the business" by the Wall Street Journal, the small but efficient organization (36 staff members and a $3 million budget) pressures some of the world's largest and most respected firms -- including Citigroup, Bank of America, JP Morgan Chase, Goldman Sachs, Home Depot, and Boise Cascade -- to adopt wide-ranging green policies that impact everything from where they source their energy to how they finance development projects.
(12/19/2006) Understanding relationships between plants and animals is key to understanding rainforest ecology. Dr. Pierre-Michel Forget of the Museum National d'Histoire Naturelle in France is a renowned expert on the interdependency between rainforest trees and seed disperses. Author of dozens of papers on tropical forest ecology, Dr Forget is increasingly concerned about deforestation and biodiversity loss in forests of the Guiana Shield region of Northern South America. In particular he sees the invasion of informal gold miners, known as garimpeiros, as a significant threat to forests in French Guiana, Suriname, Guyana and Venezuela.
(12/19/2006) As Europe frets over climate change and deforestation, threats to "Europe's largest tropical rainforest" are mounting, according to reports from French Guiana. While French Guiana is best known for its infamous Devil's Island penal colony and as the main launch site for the European Space Agency, which is responsible for more than 50% of the state's economy activity, most of the territory is covered with lowland tropical rainforest. French Guiana's forests are biologically rich with some 1,064 known species of amphibians, birds, mammals and reptiles, and 5,625 species of vascular plants according to figures from the World conservation Monitoring Center.
(12/15/2006) In recent months Ugandan president Yoweri Museveni has moved to destroy some of Uganda's last remaining primary rainforests to give land to politically-connected plantation owners. Personally intervening in two disputes, one in Mabira Forest Reserve and the other on Bugala island in Lake Victoria, Museveni has argued that his country urgently needs such projects to industrialize and bring a better quality of life to Ugandans. He would be wrong.
(12/12/2006) Last Monday, Brazil created the world's largest rainforest protected area in the northern Amazon. Covering more than 15 million hectares (57,915 square miles) -- or an area larger than England -- the network of seven new protected reserves has been met with praise by environmental groups. Instrumental in the development of the conservation project has been an organization that most people wouldn't associate with rainforest conservation but certainly should: the Gordon and Betty Moore Foundation.
(12/05/2006) Tropical deforestation is one of the largest sources of human-produced greenhouse gases yet it has no place in existing climate agreements. This has been a point of contention in negotiations as the United States has objected to some developing countries -- notably Brazil and Indonesia -- to be getting an apparent "free ride" on deforestation-related emissions in addition to emissions from fossil fuel sources. Recent negotiations have looked at this issue from a different perspective, one where developing countries would be paid by industrialized countries for reducing their deforestation rates. Globally the payoff could be immense, extending well beyond helping mitigate global warming emissions to safeguard biodiversity and important ecological services. Leading scientists have called such plans a "win-win" scenario for all parties and even the World Bank and U.N. have voiced support for the concept.
(11/28/2006) Home to perhaps half the world's terrestrial species, rainforests are the most biodiverse ecosystems on the planet. However, when one strolls through the forest, this biodiversity is rarely apparent for the simple reason that most activity in the rainforest occurs in the canopy, a layer of overlapping branches and leaves some 60-120 feet off the ground. Here, a wealth of ecological niches creates opportunities for plants and animals, including species generally considered to be ground-dwellers: crabs, kangaroos, and even earthworms. Beyond housing biodiversity, the canopy is the power source of the rainforest, with billions of tree leaves acting as miniature solar panels to convert sunlight into energy through photosynthesis. Since the rate of photosynthesis of canopy trees is so high, these plants generate higher yields of fruits, seeds, flowers, and leaves which attract and support a wide diversity of animal life. Further, as the principal site of the interchange of heat, water vapor, and atmospheric gases, the canopy also plays an important role in regulating regional and global climate.
(11/27/2006) Forest fragmentation is rapidly eroding biodiversity in the Amazon rainforest and could worsen global warming according to research to be published this week in the journal Proceedings of the National Academy of Sciences. "Rainforest trees can live for centuries, even millennia, so none of us expected things to change too fast. But in just two decades-a wink of time for a thousand year-old tree-the ecosystem has been seriously degraded." said Dr. William Laurance, a scientist at the Smithsonian Tropical Research Institute in Panama and leader of the international team of scientists that conducted the research.
(11/27/2006) Ecotourism is hot. Travel companies everywhere are slapping eco-friendly labels on their tours and hotels to attract green-minded visitors. Alas some "ecotourism" is not really good for the environment or local people. That three-week round-the-world eco-tour via private jet for just $42,950 will generate a lot of greenhouse gases as you're flying between plush lodges that import food and staff from other places. Likewise those wood carvings purchased in tourist centers may come not from indigenous artisans but a factory turning endangered rainforest hardwoods into throwaway tourist items. Heavy anchors dropped on reefs are good neither for the coral reef ecosystem nor the sustainability of the local tourism industry. So what's a true "ecotourist" to do? Is it really possible to travel without trampling culture and tradition and further soiling the environment?
(11/21/2006) Few people realize that Mexico is home to the northernmost extent of rainforests that once extended clear down to the Amazon Basin. Though diminished in extent to about 30 percent of their original range, these rainforests are still characterized by high levels of biodiversity, including such charismatic species as jaguar, howler and spider monkeys, and macaws. These forests are also inhabited by indigenous people who live in ways largely unchanged since the arrival of Columbus in the 15th century. While still threatened by encroachment and illegal activities, in recent years the Mexican government and an assortment of environmental organizations has made progress in protecting these forests. Particularly active in these conservation efforts is the Los Tuxtlas Biological Station (Estacion de Biologia Tropical Los Tuxtlas del Instituto de Biologia Universidad Nacional Autonoma de Mexico) based in Veracruz (southern Mexico). In November 2006, Dr. Alejandro Estrada, senior research scientist at Los Tuxtlas and a leading authority on these forests, answered some questions on Mexico's remaining rainforests and conservation efforts in the country.
(11/15/2006) Deep in the most remote jungles of South America, Amazon Indians are using Google Earth, Global Positioning System (GPS) mapping, and other technologies to protect their fast-dwindling home. Tribes in Suriname, Brazil, and Colombia are combining their traditional knowledge of the rainforest with Western technology to conserve forests and maintain ties to their history and cultural traditions, which include profound knowledge of the forest ecosystem and medicinal plants. Helping them is the Amazon conservation Team (ACT), a nonprofit organization working with indigenous people to conserve biodiversity, health, and culture in South American rainforests.
(11/09/2006) Troubles are mounting in one of Earth's most beautiful landscapes. Deep in the Venezuelan Amazon, among ancient forested tabletop mountains known as tepuis, crystalline rivers, and breathtaking waterfalls, illegal gold miners are threatening one of world's largest remaining blocks of wilderness, one that is home to indigenous people and strikingly high levels of biological diversity. As the situation worsens -- a series of attacks have counted both miners and indigenous people as victims -- a leading scientific organization has called for the Venezuelan government to take action.
(11/09/2006) With ecosystems ranging from Lake Tanganyika to Mt. Kilimanjaro, Tanzania is the most biodiverse country in Africa. Though Tanzania is world famous for its safari animals, the country is also home to two major biodiversity hotspots: coastal forests of Eastern Africa and the montane forests of the Eastern Arc Mountains. Tanzania has set aside nearly a quarter of its land mass in a network of protected areas and more than one-sixth of the country's income is derived from tourism, much of which comes from nature-oriented travel. Despite these conservation achievements, Tanzania's wildlands and biodiversity are not safe. Fueled by surging population growth and poverty, subsistence agriculture, fuelwood collection, and timber extraction have fragmented and degraded extensive areas that are nominally protected as parks. Hunting and unsustainable use of forest products have further imperiled ecosystems and species. In the near future, climate change looms as a major threat not only to Mt. Kilimanjaro's glaciers, which are expected to disappear within ten years, but also to Tanzania's many endemic plants and animals found in its montane forests. Working to better understand these threats and safeguard Tanzania's biodiversity for future generations is Tim Davenport, Country Director for the Wildlife conservation Society (WCS) in Tanzania.
(11/07/2006) Sri Lanka, an island off the southern-most point of India, is known as a global biodiversity hotspot for its high number of species in a relatively limited area. However this biological richness is highly threatened by one of the highest deforestation rates of primary forests in the world. In that period, the country lost more than 35 percent of its old-growth forest cover, while total forest cover was diminished by almost 18 percent. Worse, since the close of the 1990s, deforestation rates have increased by more than 25 percent. Dr Ranil Senanayake, chairman of Rainforest Rescue International, a grassroots environmental organization based in Sri Lanka, says that the key to saving the island's last forests is to "reintroduce the concept of sustainable livelihood" to the people living in and around the island's rainforests by establishing "commercially viable projects that explore the social and cultural relationships between people and ecology."
(11/05/2006) Madagascar, an island larger than France that lies off the southeastern coast of Africa, is perhaps best known for its lemurs--primates that look something like a cat crossed with a squirrel and a dog. Lemurs, which are found naturally only in Madagascar, serve as a charismatic representation of the island's biodiversity and its problems. Since the arrival of humans some 2000 years ago from southeast Asia, Madagascar has lost all of its mega fauna and more than 90 percent of its wildlands. Today forest clearing for agriculture and hunting continues to put lemurs and other endemic species at risk. The good news is that because of Madagascar's biodiversity, the island has become a top priority for global conservation. At the forefront of these efforts is the Madagascar Fauna Group (MFG), an international consortium of zoos and related organizations that work to protect Madagascar's wildlife and ecosystems, and the Duke University Lemur Center, the one of the world's leading lemur research facilities. Charlie Welch, currently a research scientist at the Duke University Lemur Center, recently answered some questions on his experiences in lemur conservation. Welch, along with his wife Andrea Katz, has worked in Madagascar for 17 years and helped transform conservation efforts in the country.
(11/01/2006) Avoided deforestation will be a hot point of discussion at next week's climate meeting in Nairobi, Kenya. Already a coalition of 15 rainforest nations have proposed a plan whereby industrialized nations would pay them to protect their forests to offset greenhouse gas emissions. Meanwhile, last month Brazil -- which has the world's largest extent of tropical rainforests and the world's highest rate of forest loss -- said it promote a similar initiative at the talks. At stake: potentially billions of dollars for developing countries. When trees are cut greenhouse gases are released into the atmosphere -- roughly 20 percent of annual emissions of such heat-trapping gases result from deforestation and forest degradation. Avoided deforestation is the concept where countries are paid to prevent deforestation that would otherwise occur. Policymakers and environmentalists alike find the idea attractive because it could help fight climate change at a low cost while improving living standards for some of the world's poorest people and preserving biodiversity and other ecosystem services. A number of prominent conservation biologists and development agencies including the World Bank and the U.N. have already endorsed the idea.
(10/31/2006) Tropical rainforests house hundreds of thousands of species of plants, many of which hold promise for their compounds which can be used to ward off pests and fight human disease. No one understands the secrets of these plants better than indigenous shamans -medicine men and women - who have developed boundless knowledge of this library of flora for curing everything from foot rot to diabetes. But like the forests themselves, the knowledge of these botanical wizards is fast-disappearing due to deforestation and profound cultural transformation among younger generations. The combined loss of this knowledge and these forests irreplaceably impoverishes the world of cultural and biological diversity. Dr. Mark Plotkin, President of the non-profit Amazon conservation Team, is working to stop this fate by partnering with indigenous people to conserve biodiversity, health, and culture in South American rainforests. Plotkin, a renowned ethnobotanist and accomplished author (Tales of a Shaman's Apprentice, Medicine Quest) who was named one of Time Magazine's environmental "Hero for the Planet," has spent parts of the past 25 years living and working with shamans in Latin America. Through his experiences, Plotkin has concluded that conservation and the well-being of indigenous people are intrinsically linked -- in forests inhabited by indigenous populations, you can't have one without the other. Plotkin believes that existing conservation initiatives would be better-served by having more integration between indigenous populations and other forest preservation efforts.
(10/26/2006) Currently, most energy production generates carbon dioxide, a potent greenhouse gas that contributes to global warming and local pollution. At the same time that carbon dioxide concentrations are rising in the atmosphere, fueling higher temperatures, burgeoning population growth of humans and livestock is producing ever-increasing amounts of organic pollution and waste. Now researchers at the Center for Biotechnology at the Biodesign Institute of Arizona State University are working on a way to solve both problems using bacteria to convert organic wastes into a source of electricity. Bruce Rittmann, Director of the Center for Environmental Biotechnology at the Biodesign Institute, and his team of researchers are developing microbial fuel cells (MFC) that can oxidize organic pollutants and create electricity from pollution.
(10/24/2006) Water is shaping up to be one of the most critical problems facing humanity. With water consumption far outstripping population growth rates due to surging industrial and agricultural demand, the World Bank estimates that 40 percent of the world's population -- more than 2.5 billion people -- are enduring some form of water scarcity. In China, where massive river relocation projects to shift water from the south to the dry north are under consideration, an official government survey found that some 300 million Chinese drink unsafe water tainted by chemicals and other contaminants, while 90% of China's cities have polluted ground water. Elsewhere, development experts say that access to reliable, safe and affordable water is key to poverty alleviation efforts and that addressing declining groundwater supplies and water pollution is be critical to raising the quality of life in poor regions.
(10/23/2006) For the Amazon, there is an immense threat looming on the horizon: climate change could well cause most of the Amazon rainforest to disappear by the end of the century. Dr. Philip Fearnside, a Research Professor at the National Institute for Research in the Amazon in Manaus, Brazil and one of the most cited scientists on the subject of climate change, understands the threat well. Having spent more than 30 years in Brazil and now recognized as one of the world's foremost experts on the Amazon rainforest, Fearnside is working to do nothing less than to save this remarkable ecosystem. Fearnside believes saving the Amazon will require a fundamental shift in perception where the Amazon is recognized as an asset beyond the current price of mahogany, soybeans, or cattle, where its value is only unlocked by its destruction. The Amazon is far worth more than this he says. It can play a key role in fighting climate change while providing economic sustenance for millions through sustainable agriculture and rational utilization of its renewable products. It can serve as a storehouse for biodiversity while at the same time ensuring reliable water supplies and moderating regional temperature and precipitation. In short, maintaining the Amazon as a viable ecosystem makes sense economically and ecologically -- it is in our best interest to preserve this resource while we still can.
(10/19/2006) Cultural Bankruptcy: Maintaining History at a Tremendous Cost in Sulawesi's Torajaland. The Torajanese people of Central Sulawesi, Indonesia, have long been renown for their extravagant celebrations of the dead in their funerals, graves and effigies. Just outside of Rantepao, the regional capital of Torajaland, ostentatious, costly and increasingly generationally divisive funerals take place on a regular basis. Like other indigenous cultures around the world, a growing rift between the young and old generations is calling the foundations of tradition into question.
(10/19/2006) High in the cloud-shrouded Yunling mountains of northwestern Yunnan and southeastern Tibet (southwestern China) lives one of the world's most elusive monkeys, the Yunnan golden or snub-nosed monkey (Rhinopithecus bieti). Despite dwelling the most extreme environment of any monkey species -- high-altitude evergreen forests at elevations from 3000 - 4500 m (9800 - 14,800 feet) where temperatures may fall below freezing for several months in a row -- today there are less than 2000 of Yunnan snub-nosed monkeys remaining. Hunting and habitat loss has brought the species, which is limited to a single mountain range and fragmented into 15 small sub-populations at risk to genetic bottlenecks and inbreeding depression, to the brink of extinction.
(10/17/2006) The world's tropical rainforests are in trouble. Spurred by a global commodity boom and continuing poverty in some of the world's poorest regions, deforestation rates have increased since the close of the 1990s. The usual threats to forests -- agricultural conversion, wildlife poaching, uncontrolled logging, and road construction -- could soon be rivaled, and even exceeded, by climate change and rising levels of carbon dioxide in the atmosphere. Understanding these threats is key to preserving forests and their ecological services for current and future generations. William F. Laurance, a distinguished scholar and president of the Association for Tropical Biology and conservation (ATBC) -- the world's largest scientific organization dedicated to the study and conservation of tropical ecosystems, is at the forefront of this effort.
(10/16/2006) Indonesia is burning again. Smoke from fires set for land-clearing in South Kalimantan (Borneo) and Sumatra are causing pollution levels to climb in Singapore, Kuala Lumpur, and Bangkok, resulting in mounting haze-related health problems, traffic accidents, and associated economic costs. The country's neighbors are again clamoring for action but ultimately the fires will burn until they are extinguished by seasonal rains in coming months
(10/09/2006) Xinjiang, China's largest and western-most province, is one of the planet's most remote and desolate regions. Covering more than one-sixth the country's territory, Xinjiang borders Tibet, Mongolia, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, and Pakistan, and is dominated by ethnic minorities, notably the Muslim Uyghurs who make up nearly half the 18 million who live in the province. Xinjiang's ethnic mix reflects its historical importance as a central part of the Silk Road, a trading route used since ancient times to transport good between East and West.
(10/07/2006) As tropical forests -- the world's biological treasure troves -- continue to dwindle, biologists are racing to devise ways to save them and their resident biodiversity. While many conservation biologists talk about population viability analysis and intricacies of reserve layouts, David L. Pearson, a research professor at the School of Life Sciences at Arizona State University (ASU) in Tempe, Arizona, focuses on a different approach: education.
