Did palm oil expansion play a role in the Ebola crisis?
(01/14/2015) The Ebola outbreak in West Africa may have been the result of complex economic and agricultural policies developed by authorities in Guinea and Liberia, according to a new commentary in Environment and Planning A. Looking at the economic activities around villages where Ebola first emerged, the investigators analyzed a shift in land-use activities in Guinea's forested region, particularly an increase in oil palm.
Walking the walk: zoo kicks off campaign for orangutans and sustainable palm oil
(10/20/2014) If you see people wearing orange this October, it might not be for Halloween, but for orangutans. Chester Zoo’s conservation campaign, Go Orange for Orangutans, kicks off this month for its second year. The campaign aims to raise money, and awareness, for orangutans in Borneo, which have become hugely impacted by deforestation often linked to palm oil plantations.
Turning point for Peru's forests? Norway and Germany put muscle and money behind ambitious agreement
(09/24/2014) From the Andes to the Amazon, Peru houses some of the world's most spectacular forests. Proud and culturally-diverse indigenous tribes inhabit the interiors of the Peruvian Amazon, including some that have chosen little contact with the outside world. And even as scientists have identified tens-of-thousands of species that make their homes from the leaf litter to the canopy.
Forgotten species: the exotic squirrel with a super tail
(08/13/2014) With among the world's largest tails compared to body-size, the tufted ground squirrel just might be the most exotic squirrel species on the planet. Found only on the island of Borneo, this threatened species is also surrounded by wild tales, including the tenacity to take down a deer for dinner. New research explores the squirrel's monster tail and whether other tales about it may be true.
Is Cameroon becoming the new Indonesia? Palm oil plantations accelerating deforestation
(06/25/2014) The potential for new laws governing the use of forest resources this year in Cameroon promises an opportunity to stem the rapid loss of forest in the biologically diverse country. But the changes may ultimately not be what’s needed to save Cameroon’s forests.
Next big idea in forest conservation? Learning from innovations to make REDD+ work
(06/12/2014) A scientist at the Center for International Forestry Research (CIFOR) in Brazil, Dr. Amy Duchelle coordinates research on the effectiveness, efficiency, equity, and co-benefits of REDD+ initiatives at the sub-national level in Latin America as part of CIFOR's Gloal Comparative Study on REDD+.
Greenpeace accuses controversial palm oil company and Cameroon government of illegal logging
(05/28/2014) Greenpeace has just accused one of the world's most controversial oil palm companies, Herakles Farms, of colluding with top government officials to sell off illegally logged timber to China. According to a new report, an agreement between Cameroon's Minister of Forestry and Herkales Farms—through a shell company—could torpedo the country's agreement with the EU for better timber management.
Next big idea in forest conservation? Privatizing conservation management
(03/07/2014) Is it possible to equitably divide the planet’s resources between human and non-human societies? Can we ensure prosperity and rights both to people and to the ecosystems on which they rely? In the island archipelago of Indonesia, these questions become more pressing as the unique ecosystems of this global biodiversity hotspot continue to rapidly vanish in the wake of land conversion (mostly due to palm oil, poor forest management and corruption. For 22 years, Dr. Erik Meijaard has worked in Indonesia. Now, from his home office in the capitol city, Jakarta, he runs the terrestrial branch of an independent conservation consultancy, People and Nature Consulting International (PNCI).
Dietary diversity: key to defending tropical ecosystems
(03/06/2014) A new study published in the Proceedings of the National Academy of Sciences (PNAS) points to the homogenization of global diets over the past fifty years. It shows that worldwide production of traditional staples such as millet, rye, sorghum, yams and cassava have been in decline. Instead, the world's population increasingly relies on a relatively small number of 'megacrops' like wheat, corn and soy, raising serious concerns for global food security, human nutrition, and the genetic diversity of crops.
The lemur end-game: scientists propose ambitious plan to save the world's most imperiled mammal family
(02/20/2014) Due to the wonderful idiosyncrasies of evolution, there is one country on Earth that houses 20 percent of the world's primates. More astounding still, every single one of these primates—an entire distinct family in fact—are found no-where else. The country is, of course, Madagascar and the primates in question are, of course, lemurs. But the far-flung island of Madagascar, once a safe haven for wild evolutionary experiments, has become an ecological nightmare. Overpopulation, deep poverty, political instability, slash-and-burn agriculture, illegal logging for lucrative woods, and a booming bushmeat trade has placed 94 percent of the world's lemurs under threat of extinction, making this the most imperiled mammal group on the planet. But, in order to stem a rapid march toward extinction, conservationists today publicized an emergency three year plan to safeguard 30 important lemur forests in the journal Science.
Scientists: well-managed forest restoration benefits both biodiversity and people
(12/16/2013) In November this year, the world was greeted by the dismaying news that deforestation of the Brazilian Amazon jumped 28% in the past year. The year 2013 also holds the dubious distinction of being the first time since humans appeared on the planet, that carbon concentrations in the atmosphere rose to 400 parts per million. A map by Google revealed that Russia, Brazil, the United States, Canada and Indonesia all displayed over 10 million hectares of gross forest loss from 2000-2012, with the highest deforestation rate occurring in Malaysia.
Camera traps find less mammals than expected in Costa Rican corridor
(12/16/2013) A new study using camera traps in mongabay.com's open-access journal Tropical Conservation Science has surveyed the diversity of medium and large-sized predators in the San Juan-La Selva biological corridor in Costa Rica, whilst also demonstrating how alteration of habitat is affecting the use of this corridor.
Canopy crusade: world's highest network of camera traps keeps an eye on animals impacted by gas project
(11/21/2013) Oil, gas, timber, gold: the Amazon rainforest is rich in resources, and their exploitation is booming. As resource extraction increases, so does the development of access roads and pipelines. These carve their way through previously intact forest, thereby interrupting the myriad pathways of the species that live there. For species that depend on the rainforest canopy, this can be particularly problematic.
Tapirs, drug-trafficking, and eco-police: practicing conservation amidst chaos in Nicaragua
(10/10/2013) Nicaragua is a nation still suffering from deep poverty, a free-flowing drug trade, and festering war-wounds after decades of internecine fighting. However, like any country that has been largely defined by its conflicts, Nicaragua possesses surprises that overturn conventional wisdom. Not the least of which is that the Central American country is still home to big, stunning species, including jaguars, giant anteaters, pumas, and the nation's heaviest animal, the Baird's tapir (Tapirus bairdii). Still, not surprisingly given the nation's instability, most conservationists have avoided Nicaragua. But tapir-expert Christopher Jordan, who has worked in the country for over four years, says he wouldn't have it any other way.
Bornean elephant meets palm oil: saving the world's smallest pachyderm in a fractured landscape
(10/01/2013) In the Malaysian state of Sabah, where most conservation students are still foreigners—either European or American—Nurzahafarina Othman stands out: not only is she Malaysian, a Muslim, and a mother of a young daughter, but she's rapidly becoming a top researcher and champion for the world's smallest elephant: the Bornean elephant (Elephas maximus borneensis). Although sometimes described as a pygmy elephant, they still weigh 2,000 kilograms (4,400 pounds). The origin of these 'tiny' elephants in Malaysian Borneo have baffled scientists for decades.
Featured video: Sumatra's last elephants versus palm oil
(08/05/2013) A new video by The Ecologist documents the illegal destruction of the Leuser protected area in Sumatra for palm oil production, a vegetable oil which has become ubiquitous in many mass-produced foods and cosmetics. The destruction of the forest has pushed elephants and people together, leading to inevitable conflict with casualties on both sides. Elephants are increasingly viewed as agricultural pests for crop-raiding while locals—some of them squatting in protected land—lack the means and resources to keep elephants at bay. Meanwhile, palm oil plantations often see elephants as a threat to the palms.
Saving Gorongosa: E.O. Wilson on protecting a biodiversity hotspot in Mozambique
(05/30/2013) If you fly over the Great African Rift Valley from its northernmost point in Ethiopia, over the great national parks of Kenya and Tanzania, and follow it south to the very end, you will arrive at Gorongosa National Park in central Mozambique. Plateaus on the eastern and western sides of the park flank the lush valley in the center. Dramatic limestone cliffs, unexplored caves, wetlands, vast grasslands, rivers, lakes, and a patchwork of savanna and forest contribute to the incredible diversity of this park. What makes this place truly unique, however, is Mount Gorongosa—a towering massif that overlooks the valley below.
Central America's largest forest under siege by colonists
(05/06/2013) In the last four years, invading land speculators and peasants have destroyed 150,000 hectares (370,000 acres) of rainforest in Nicaragua's Bosawás Biosphere Reserve, according to the Mayangna and Miskito indigenous peoples who call this forest home. Although Nicaragua recognized the land rights of the indigenous people in 2007, the tribes say the government has not done near-enough to keep illegal settlers out despite recent eviction efforts.
Ant communities more segregated in palm oil plantations than rainforest
(03/21/2013) Ants are an important ecological group in both degraded and natural habitats. They interact with many other species and mediate a range of ecological processes. These interactions are often interpreted in the context of ant mosaics, where dominant species form strict territories, keeping other ants out. This segregation between ant species is well-documented in monoculture plantations. Now new research published in Ecography has shown that these changes are driven by the replacement of rainforests with monocultures and not the arrival of non-native species.
Activists warn of industrial palm oil expansion in Congo rainforest
(02/21/2013) Industrial oil palm plantations are spreading from Malaysia and Indonesia to the Congo raising fears about deforestation and social conflict. A new report by The Rainforest Foundation UK (RFUK), dramatically entitled The Seeds of Destruction, announces that new palm oil plantations in the Congo rainforest will soon increase fivefold to half a million hectares, an area nearly the size of Delaware. But conservationists warn that by ignoring the lessons of palm oil in Southeast Asia, this trend could be disastrous for the region's forests, wildlife, and people.
Controversial palm oil project concession in Cameroon is 89 percent 'dense natural forest'
(02/21/2013) Satellite mapping and aerial surveys have revealed that a controversial palm oil concession in Cameroon is almost entirely covered by "dense natural forest," according to a new report by Greenpeace. The activist group alleges that the concession, owned by Herakles Farms, is under 89 percent forest cover. The U.S.-based corporation intends to build a 70,000 hectare palm oil plantation in a region surrounded by four protected areas, including Korup National Park, but has faced stiff criticism from numerous environmental groups as well as conflict with locals.
From slash-and-burn to Amazon heroes: new video series highlights agricultural transformation
(01/31/2013) A new series of short films is celebrating the innovation of rural farmers in the Manu region of Peru. Home to jaguars, macaws, and tapirs, the Manu region is also one of the top contenders for the world's most biodiverse place. It faces a multitude of threats from road-building to mining to gas and oil concessions. Still the impact of smallscale slash-and-burn farming—once seen as the greatest threat to the Amazon and other rainforest—may be diminishing as farmers, like the first film's Reynaldo (see below), turn to new ways of farming, ones that preserve the forest while providing a better life overall.
New palm oil concession imperils orangutan population in Borneo
(01/28/2013) Three conservation groups warn that a proposed palm oil plantation puts a significant Bornean orangutan (Pongo pygmaeus) population at risk in the Malaysian state of Sabah. The plantation, which would cover 400 hectares of private forest land, lies adjacent to Kulamba Wildlife Reserve, home to 480 orangutans.
Forests, farming, and sprawl: the struggle over land in an Amazonian metropolis
(12/04/2012) The city of Parauapebas, Brazil is booming: built over the remains of the Amazon rainforest, the metropolis has grown 75-fold in less than 25 years, from 2,000 people upwards of 150,000. But little time for urban planning and both a spatial and mental distance from the federal government has created a frontier town where small-scale farmers struggle to survive against racing sprawl, legal and illegal mining, and a lack of investment in environmental protection. Forests, biodiversity, and subsistence farmers have all suffered under the battle for land. In this, Parauapebas may represent a microcosm both of Brazil's ongoing problems (social inequality, environmental degradation, and deforestation) and opportunity (poverty alleviation, reforestation, and environmental enforcement).
Featured video: how locals depend on Kalimantan's vanishing forests
(11/27/2012) A new video explores local indigenous views of the forests of Kalimantan or Indonesian Borneo. Having depended on the rainforest ecosystems for centuries, indigenous groups now find themselves under pressure to exploit forest for logging, coal mining, or industrial plantations. While biodiversity, carbon sequestration, and other ecosystem services are at stake, the forests are also deeply intertwined with the culture and way-of-life for indigenous group.
Photos reveal destruction of Cameroon rainforest for palm oil
(11/26/2012) Newly released photos by Greenpeace show the dramatic destruction of tropical forest in Cameroon for an oil palm plantation operated by SG Sustainable Oils Cameroon (SGSOC), a subsidiary of the U.S. company Herakles Farm. The agriculture company is planning to convert 73,000 hectares to palm oil plantations on the edge of several protected areas, but has faced considerable opposition from environmentalists and some local communities. In addition to the aerial photos, Greenpeace alleges that ongoing forest clearing by Herakles is illegal since the companies 99-year lease has yet to be fully approved by the Cameroonian government.
Over 100,000 farmers squatting in Sumatran park to grow coffee
(11/06/2012) Sumatra's Bukit Barisan Selatan National Park—home to the Critically Endangered Sumatran rhinos, tigers, and elephants—has become overrun with coffee farmers, loggers, and opportunists according to a new paper in Conservation and Society. An issue facing the park for decades, the study attempted for the first time to determine the number of squatters either living in or farming off Bukit Barisan Selatan National Park, a UNESCO World Heritage Site; the rough census—over 100,000 people—shocked scientists.
New rare frog discovered in Sri Lanka, but left wholly unprotected
(11/05/2012) Sri Lanka, an island country lying off the southeast coast of India, has long been noted for its vast array of biodiversity. Islands in general are renowned for their weird and wonderful creatures, including high percentages of endemic species—and Sri Lanka, where scientists recently discovered a new frog species, is no exception.
Is your Halloween candy linked to rainforest destruction?
(10/11/2012) A campaign by the Cheyenne Mountain Zoo hopes to raise awareness about the link between Halloween candy and deforestation in Indonesia and Malaysia. Employing the images of Critically Endangered orangutans, the zoo urges consumer to only buy candy containing eco-certified palm oil by the Round Table on Sustainable Palm Oil (RSPO).
90 percent of oil palm plantations came at expense of forest in Kalimantan
(10/08/2012) From 1990 to 2010 almost all palm oil expansion in Kalimantan came at the expense of forest cover, according to the most detailed look yet at the oil palm industry in the Indonesian state, published in Nature: Climate Change. Palm oil plantations now cover 31,640 square kilometers of the state, having expanded nearly 300 percent since 2000. The forest loss led to the emission of 0.41 gigatons of carbon, more than Indonesia's total industrial emissions produced in a year. Furthermore the scientists warn that if all current leases were converted by 2020, over a third of Kalimantan's lowland forests outside of protected areas would become plantations and nearly quadruple emissions.
Roundtable on Sustainable Palm Oil hits 10 year mark
(10/04/2012) The Roundtable on Sustainable Palm Oil (RSPO) is holding its tenth annual meeting later this month. The initiative, which aims to improve the social and environmental performance of palm oil production through a certification standard, has advanced considerably during that time, moving from an idea to a reality: RSPO-certified palm oil now accounts for 12 percent of global palm oil production. Yet the RSPO is not without controversy. Some palm oil companies say its criteria are too costly to adopt and are therefore discriminatory, while environmental critics argue its bar for "sustainable" palm oil is too low and the loopholes allow producers to claim membership even if they aren't actually producing certified palm oil across all their holdings. Nonetheless the RSPO has support from many of the world's largest palm oil producers, traders, and consumers as well as the biggest NGOs.
Learning to live with elephants in Malaysia
(09/18/2012) Humans and elephants have a lot in common: both are highly intelligent, intensely social, and both are capable of having a massive impact on their local environments. Given their similarities, it might not be surprising that elephants and human have often run afoul of one another. Conflict between these two great species has probably been going on for thousands of years, but as human populations have grown dramatically, elephant populations have been crippled and forced into smaller-and-smaller pockets. No-where is this more true than in Southeast Asia.
Photos: camera traps capture wildlife bonanza in Borneo forest corridor
(09/10/2012) Camera traps placed in a corridor connecting two forest fragments have revealed (in stunning visuals) the importance of such linkages for Borneo's imperiled mammals and birds. Over 18 months, researchers with the Sabah Wildlife Department (SWD) and the Danau Girang Field Centre (DGFC) have photographed wildlife utilizing the corridor located in the Lower Kinabatangan Wildlife Sanctuary in Malaysian Borneo.
Recommendations to save India's Western Ghats creates political stir
(08/20/2012) A massive expert panel report on the conservation of the Western Ghats has caused a political stir in India. The report, headed by noted ecologist Madhav Gadgil, recommends that the government phase out mining projects, cancel damaging hydroelectric projects, and move toward organic agriculture in ecologically-sensitive sections of the Ghats. The report, which was leaked after the government refused to release it, has yet to be implemented. Recently dubbed a UNESCO World Heritage Site, the Western Ghats is one of India's largest wildernesses and home to thousands of species, many found no-where else.
Hundreds of hotspots burn Tesso Nilo National Park, threatening elephants
(08/08/2012) From June to July, hundreds of fires spread in Tesso Nilo National Park in Indonesia. Based on the data from World Wide Fund for Wildlife (WWF) Program-Riau, fire hotspots reached their peak in the third week of June. As of early July, fires, which were triggered a month earlier, could not be totally extinguished.
Forest cover falls 9% in East Africa in 9 years
(07/31/2012) Forest cover in East Africa has dropped by 9.3 percent from 2001-2009, according to a new paper published in the open-access journal PLoS ONE. Looking at 12 countries in the region, the scientists found that, worryingly, forests were particularly hard hit near protected areas. Usually thought of as a region of vast savannas, such as the Serengeti, East Africa is also home to incredibly biodiverse tropical forests, including coastal forests, rich montane forests, and the eastern portion of the Congo Rainforest.
'National scandal:' foreign companies stripped Papua New Guinea of community-owned forests
(07/30/2012) Eleven percent of Papua New Guinea's land area has been handed over to foreign corporations and companies lacking community representation, according to a new report by Greenpeace. The land has been granted under controversial government agreements known as Special Agricultural and Business Leases (SABLs), which scientists have long warned has undercut traditional landholding rights in the country and decimated many of Papua New Guinea's biodiverse rainforests. To date, 72 SABLs have been granted—mostly to logging companies—covering an area totaling 5.1 million hectares or the size of Costa Rica.
Experts dispute recent study that claims little impact by pre-Columbian tribes in Amazon
(07/05/2012) A study last month in the journal Science argued that pre-Columbian peoples had little impact on the western and central Amazon, going against a recently composed picture of the early Amazon inhabited by large, sophisticated populations influencing both the forest and its biodiversity. The new study, based on hundreds of soil samples, theorizes that indigenous populations in much of the Amazon were tiny and always on the move, largely sticking to rivers and practicing marginal agriculture. However, the study raised eyebrows as soon as it was released, including those of notable researchers who openly criticized its methods and pointed out omissions in the paper, such as no mention of hundreds of geoglyphs, manmade earthen structures, found in the region.
Congolese experts needed to protect Congo Basin rainforests
(06/20/2012) This summer, the Democratic Republic of Congo (DRC) is expected to approve a new higher education strategy which the country has developed with the World Bank and other international donors. The shape of this educational reform initiative will be critical to Congo's future in many ways. It could finally offer Congo’s long-suffering people a route into the 21st century. It will also help determine the future of the DRC’s forests. Nearly half of the Congo Basin’s remaining rainforest is in the DRC—yet the critical role of Congolese experts in forestry, agricultural science, wildlife management and other rural sciences in protecting this forest is not widely recognized.
Over 700 people killed defending forest and land rights in past ten years
(06/19/2012) On May 24th, 2011, forest activist José Cláudio Ribeiro da Silva and his wife, Maria do Espírito Santo da Silva, were gunned down in an ambush in the Brazilian state of Pará. A longtime activist, José Cláudio Ribeiro da Silva had made a name for himself for openly criticizing illegal logging in the state which is rife with deforestation. The killers even cut off the ears of the da Silvas, a common practice of assassins in Brazil to prove to their employers that they had committed the deed. Less than a year before he was murdered, da Silva warned in a TEDx Talk, "I could get a bullet in my head at any moment...because I denounce the loggers and charcoal producers."
Jaguars photographed in palm oil plantation
(06/06/2012) As the highly-lucrative palm oil plantation moves from Southeast Asia to Africa and Latin America, it brings with it concerns of deforestation and wildlife loss. But an ongoing study in Colombia is finding that small palm oil plantations may not significantly hurt at least one species: the jaguar. Researchers in Magdalena River Valley have taken the first ever photos of jaguars in a palm plantation, including a mother with two cubs, showing that the America's biggest cat may not avoid palm oil plantations like its Asian relative, the tiger.
Indigenous group paid $0.65/ha for forest worth $5,000/ha in Indonesia
(05/23/2012) A palm oil company has paid indigenous Moi landowners in Indonesian Papua a paltry $0.65 per hectare for land that will be worth $5,000 a hectare once cultivated, according to a new report by the Environmental Investigation Agency (EIA) and Indonesian NGO, Telepak. The report outlines similar disadvantageous deals in timber with the same companies breaking their promises of bringing education and infrastructure.
Featured video: How to save the Amazon
(04/22/2012) The past ten years have seen unprecedented progress in fighting deforestation in the Amazon. Indigenous rights, payments for ecosystem services, government enforcement, satellite imagery, and a spirit of cooperation amongst old foes has resulted in a decline of 80 percent in Brazil's deforestation rates.
Police hired by loggers in Papua New Guinea lock locals in shipping containers
(04/16/2012) Locals protesting the destruction of their forest in Papua New Guinea for two palm oil plantations say police have been sent in for a second time to crack-down on their activities, even as a Commission of Inquiry (COI) investigates the legality of the concession. Traditional landowners in Pomio District on the island East New Britain say police bankrolled by Malaysian logging giant Rimbunan Hijau (RH) have terrorized the population, including locking people in shipping containers for three consecutive nights. The palm oil concessions belongs to a company known as Gilford Limited, which locals say is a front group for RH.
Scientists say massive palm oil plantation will "cut the heart out" of Cameroon's rainforest
(03/15/2012) Eleven top scientists have slammed a proposed palm oil plantation in a Cameroonian rainforest surrounded by five protected areas. In an open letter, the researchers allege that Herakles Farm, which proposes the 70,000 hectare plantation in southwest Cameroon, has misled the government about the state of the forest to be cleared and has violated rules set by the Roundtable on Sustainable Palm Oil (RSPO), of which it's a member. The scientists, many of whom are considered leaders in their field, argue that the plantation will destroy rich forests, imperil endangered species, and sow conflict with local people.
Climate change could increase fires, logging, and hunting in rainforests
(03/13/2012) The combined impacts of deforestation and climate change will bring a host of new troubles for the world's tropical rainforests argues a new study in Trends in Ecology and Evolution. Drying rainforests due to climate change could lead to previously inaccessible forests falling to loggers, burning in unprecedented fires, or being overexploited by hunters.
Rally calls on Brazil President to veto new forest code
(03/07/2012) A coalition of 200 organizations, known as the Comitê Brasil in Defense of Forests and Sustainable Development, rallied today in Brasilia against proposed changes to Brazil's Forestry Code. The code, which was supposed to be voted on this week but has been delayed to shore up more support, would make changes in over 40-year-old code that some conservationists fear could lead to further deforestation in the Amazon. Protestors called on the President of Brazil, Dilma Rousseff, to veto the bill as it stands now, holding signs exclaiming, "Veta Dilma!" ("Veto it Dilma!").
Innovative program seeks to safeguard Peruvian Amazon from impacts of Inter-Oceanic Highway
(03/06/2012) Arbio was begun by Michel Saini and Tatiana Espinosa Q. in the Peruvian Amazon region of Madre de Dios. The project focuses on a protective response to the increased encroachment and destructive land use driven by development. The recent construction of the Inter-Oceanic Highway in the Madre de Dios area presents an enormous threat to forest biodiversity. Arbio provides opportunities to help establish a buffer zone near the road to limit intrusive agricultural and deforestation activities.
Tourism for biodiversity in Tambopata
(02/27/2012) Research and exploration in the Neotropics are extraordinary, life-changing experiences. In the past two decades, a new generation of collaborative projects has emerged throughout Central and South America to provide access to tropical biodiversity. Scientists, local naturalists, guides, students and travelers now have the chance to mingle and share knowledge. Fusion programs offering immersion in tropical biology, travel, ecological field work, and adventure often support local wilderness preservation, inspire and educate visitors.
Humans drove rainforest into savannah in ancient Africa
(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.
