(02/09/2012) Three thousand years ago (around 1000 BCE) several large sections of the Congo rainforest in central Africa suddenly vanished and became savannah. Scientists have long believed the loss of the forest was due to changes in the climate, however a new study in Science implicates an additional culprit: humans. The study argues that a migration of farmers into the region led to rapid land-use changes from agriculture and iron smelting, eventually causing the collapse of rainforest in places and a rise of grasslands. The study has implications for today as scientists warn that the potent combination of deforestation and climate change could flip parts of the Amazon rainforest as well into savannah.
(01/12/2012) A new study in Science argues that reducing methane and black carbon emissions would bring global health, agriculture, and climate benefits. While such reductions would not replace the need to reduce CO2 emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added benefits of saving lives and boosting agricultural yields. In addition, the authors contend that dealing with black carbon and methane now would be inexpensive and politically feasible.
(01/04/2012) It may appear unintuitive that special toilets could benefit hippos and other wetland species, but the Center for Rural Empowerment and the Environment (CREE) has proven the unique benefits of new toilets in the Dunga Wetlands on Lake Victoria's Kenyan side. By building ecologically-sanitary (eco-san) toilets, CREE has managed to alleviate some of the conflict that has cropped up between hippos and humans for space.
(12/19/2011) Owing to the high yield of the African oil palm tree, palm oil is today the cheapest commercial source of edible oil. But oil palm expansion in recent decades has at times had high indirect costs, including destruction of biologically diverse rainforests and further marginalization of forest-dependent people, especially in southeast Asia. Concerns over the environmental and social impact of palm oil production in the spurred a group of palm oil producers, processors, and buyers to team up with conservation groups to form the Roundtable on Sustainable Palm Oil (RSPO) in 2004. But a big question looms over all certification efforts: will the world's largest importers of palm oil — India and China — buy it?
(12/08/2011) Researchers have garnered further evidence for a smoking gun behind the fall of the great Maya civilization: deforestation. At the American Geophysical Union (AGU) conference, climatologist Ben Cook presented recent research showing how the destruction of rainforests by the Mayan ultimately led to declines in precipitation and possibly civilization-rocking droughts. While the idea that the Maya may have committed ecological-suicide through deforestation has been widely discussed, including in Jared Diamond's popular book Collapse, Cook's findings add greater weight to the theory.
(11/21/2011) After a threat of lawsuit, Dole Inc. has abandoned a banana plantation in Somawathiya National Park in Sri Lanka. The US-based food giant had partnered with a local company, Letsgrow Ltd, to grow bananas for export markets at the bank of the Mahaweli River, but Dole ran into trouble when local conservation organizations pointed out they were illegally destroying forest and planting crops in Somawathiya National Park, home to elephants and many other imperiled species. Local group, Environmental Foundation Limited (EFL), obtained past and current satellite images to prove that the company was operation within the park.
(11/08/2011) Mingling with wild grazers, such as zebra, is better for cattle than dining alone—during the wet season, at least—according to researchers in Kenya. Their new study crumbles the longstanding assumption that social grazing always leads to food fights. Kenya’s wildlife population is in a critical decline, partly due to kill-offs by ranchers who see zebra, wildebeest, antelope and other grazers strictly as competition for their cattle. But scientists at the Mpala Research Center in central Kenya suspected there might be natural accords between grazers.
(10/13/2011) At the end of this month the UN predicts global population will hit 7 billion people, having doubled from 3.5 billion in less than 50 years. Yet even as the Earth hits this new milestone, one billion people do not have enough food; meanwhile the rapid expansion of agriculture is one of the leading causes of global environmental degradation, including greenhouse gas emissions, destruction of forests, marine pollution, mass extinction, water scarcity, and soil degradation. So, how do we feed the human population—which continues to rise and is expected to hit nine billion by 2050—while preserving the multitude of ecosystem services that support global food production? A new study in Nature proposes a five-point plan to this dilemma.
(10/11/2011) Meat consumption and production remains on the rise, according to a new report Worldwatch Institute, with large-scale environmental impacts especially linked to the spread of factory farming. According to the report, global meat production has tripled since 1970, and jumped by 20 percent since 2000 with consumption rising significantly faster than global population.
(10/02/2011) Girl Scouts USA has announced that it will lessen palm oil in its ubiquitous cookies by using alternatives when possible and cutting overall usage. The organization also committed to purchasing GreenPalm certificates for all of its palm oil in order to financially support more environmentally sustainable palm oil, even if the palm oil in the cookies is not.
(09/26/2011) Aggressively expanding sugarcane ethanol is putting Brazil's nearly-vanished Atlantic Forest at risk, according to an opinion piece in mongabay.com's open-access journal Tropical Conservation Science. Already down to less than 12 percent of its original extent, the Atlantic Forest—home to over 7,000 species that survive no-where else—is facing a new peril from ethanol, used as an alternative to gasoline and often touted as 'green' or 'environmentally-sustainable'.
(09/26/2011) A new survey recorded 125 birds in Papua New Guinea's Waria Valley, of which an astounding 43 percent were endemic to the island. The survey, published in mongabay.com's open-access journal Tropical Conservation Science, was the first of its kind for the rainforest-studded valley and found that bird populations were most diverse and abundant in primary forests. The bird surveys were carried out in four different habitats including primary forest, primary forest edges, secondary forest edges, and agricultural landscape.
(09/13/2011) Industrial palm oil production is coming to Africa, its ancestral home. And like other places where expansion has occurred rapidly, the crop is spurring hope for economic development while generating controversy over its potential impacts. The world's most productive oil seed has been a boon to southeast Asian economies, but the looming arrival of industrial plantations in Africa is raising fears that some of the same detriments that have plagued leading producers Malaysia and Indonesia—deforestation, greenhouse gas emissions, biodiversity loss, conflicts with local people, social displacement, and poor working conditions—could befall one of the world’s most destitute regions. While there is no question that oil palm is a highly lucrative crop that can contribute to economic development, there is also little doubt that conversion of native forests for plantations exacts a heavy toll on the environment. The apparent conflict seems to pit agroindustrial goliaths against greens, with communities falling somewhere in between. But Herakles, a New York-based investment firm planning to construct a 60,000-hectare plantation in the Central African country of Cameroon, says its approach will bridge this gap between economic development and the environment. Social and environmental campaigners are skeptical.
(09/01/2011) Given that we have very likely entered an age of mass extinction—and human population continues to rise (not unrelated)—researchers are scrambling to determine the best methods to save the world's suffering species. In the midst of this debate, a new study in Science, which is bound to have detractors, has found that setting aside land for strict protection coupled with intensive farming is the best way to both preserve species and feed a growing human world. However, other researchers say the study is missing the point, both on global hunger and biodiversity.
(08/23/2011) Luangwa Valley in Zambia is home to stunning scenes of Africa wildlife: elephants, antelopes, zebra, buffalo, leopards, hyena, and lions all thrive in Luangwa's protected areas, while the Luangwa River is known for multitude of snapping crocodiles and its superabundant herds of hippos. In fact, the area's hippos were filmed for the BBC's program Life, including a dramatic battle between two males (see below). Yet as in many such places in Africa, abundant plains and forest wildlife bump up against the needs of impoverished local people. The resulting conflict usually ends in large-scale wildlife declines; the same trend was documented in the Luangwa Valley until a unique initiative began to make a difference not only in the life of animals, but of people as well.
(08/08/2011) When one thinks of the world's great rainforests the Amazon, Congo, and the tropical forests of Southeast Asia and Indonesia usually come to mind. Rarely does India—home to over a billion people—make an appearance. But along India’s west coast lies one of the world's great tropical forests and biodiversity hotspots, the Western Ghats. However it's not just the explosion of life one finds in the Western Ghats that make it notable, it's also the forest's long—and ongoing—relationship to humans, lots of humans. Unlike many of the world's other great rainforests, the Western Ghats has long been a region of agriculture. This is one place in the world where elephants walk through tea fields and tigers migrate across betel nut plantations. While wildlife has survived alongside humans for centuries in the region, continuing development, population growth and intensification of agriculture are putting increased pressure on this always-precarious relationship. In a recent paper in Biological Conservation, four researchers examine how well agricultural landscapes support biodiversity conservation in one of India's most species-rich landscapes.
(08/01/2011) Among conservationists and biologists, the mega-island of Borneo is a sort of Mecca. Its rich plant and animal biodiversity, as well as high degree of endemism (unique species found nowhere else) make it a naturalist's dream. There is one aspect of this biological richness which applies to the wellbeing and happiness of all of Borneo’s residents, human and animal, in a very direct way: fruit. From wild forest berries to juicy cultivated rambutans, fruit permeates the ecology, landscape and culture of Borneo. On the island there are over 70 wild fruit trees species and around 45 cultivated species that are consumed by people (1). Science has certainly not yet documented all the fruit consumed by wildlife, but we know that the total must be over 500 species.
(07/06/2011) Over the past twenty years Brazil has emerged as an agricultural superpower: today it is the largest exporter beef, sugar, coffee, and orange juice, and the second largest producer of soybeans. While much of this growth has been fueled by a sharp increase in productivity resulting from improved breeding stock and technological innovation, Brazil has benefited from large expanses of available land in the Amazon and the cerrado, a grassland ecosystem. But agricultural growth in Brazil has always been limited — at least on paper — by its environmental laws. Under the country's Forest Code, landowners in the Amazon must keep 80 percent of their land forested.
(06/19/2011) Africa's forests are fast diminishing to the detriment of climate, biodiversity, and millions of people of dependent on forest resources for their well-being. But is the full conservation of Africa's forests necessary to mitigate global climate change and ensure environmental stability in Africa? A new report by The Forest Philanthropy Action Network (FPAN), a non-profit that provides research-based advice on funding forest conservation, argues that only the full conservation of African forests will successfully protect carbon stocks in Africa.
(06/14/2011) For years now, environmentalists have become accustomed to associating palm oil with large-scale destruction of rainforests across Malaysia and Indonesia. Campaigners have linked palm oil-containing products like Girl Scout cookies and soap products to smoldering peatlands and dead orangutans. Now with Brazil announcing plans to dramatically scale-up palm oil production in the Amazon, could the same fate befall Earth's largest rainforest? With this potential there is a frenzy of activity in the Brazilian palm oil sector. Yet there is a conspicuous lack of hand wringing by environmentalists in the Amazon. The reason: done right, oil palm could emerge as a key component in the effort to save the Amazon rainforest. Responsible production there could even force changes in other parts of the world.
