U.S. and Brazilian scientists led by William Laurance of the Smithsonian Tropical Research Institute find that deforestation rates in the Brazilian Amazon have accelerated over the last decade. Analyzing deforestation estimates based on satellite images of the Amazon since 1978, the team reports that - contrary to Brazilian government claims that threats to Amazonian forests have fallen in recent years because of improved environmental laws and public attitudes - rates of deforestation have risen sharply since 1995. (2002-01-14)

New study details future of oil and gas development in the Western Amazon
The western Amazon -- a vast region encompassing the Amazonian portions of Bolivia, Colombia, Ecuador, Peru, and western Brazil -- is one of the world's last high-biodiversity wilderness landscapes. It is also home to an active hydrocarbon (oil and gas) sector, characterized by operations in extremely remote areas that require new access routes. (2015-01-29)

Half of all Amazonian tree species may be globally threatened
The study also suggests that Amazonian parks, reserves, and indigenous territories, if properly managed, will protect most of the threatened species. The findings were announced by a research team comprising 158 researchers from 21 countries, led by Hans ter Steege of Naturalis Biodiversity Center in the Netherlands and Nigel Pitman of the Field Museum in Chicago, USA.

Scientists see that sea surface temperature impacts drought and flooding in the Amazon rainforest
Rainfall patterns in the Amazon change when humans alter the land during deforestation and farming, causing some areas to suffer drought while other areas succumb to floods. Now, Rong Fu, an atmospheric scientist at the Georgia Institute of Technology, has found that the ocean surface temperature has as much of an impact on rainfall as land cover changes do. (1999-12-14)

The influence of hydropower dams on river connectivity in the Andes Amazon
Hydropower dams in the Andes Amazon significantly disturb river connectivity in this region, and consequently, the many natural and human systems these rivers support, according a new study. The results challenge previous research that collectively underestimates these dams' effects, the authors say. Given the importance of the Andes Amazon rivers to more (2018-01-31)

New study examines effects of drought in the Amazon
Recent research surrounding the impact of drought in the Amazon has provided contradictory findings as to how tropical forests react to a drier and warmer climate. A new study in the Aug. 2 Early Edition of PNAS examines the response of Amazon forests to variations in climate conditions, specifically considering how those changes may influence forest productivity. These findings provide possible context for why previous studies have offered varying conclusions. (2010-08-02)

New mathematical simulations of climate behavior by Duke University researchers indicate that deforestation in the Amazon can cause a reduction of rainfall in the Midwestern United States and the Dakotas in the summer, when precipitation is most needed for agriculture. (2002-10-24)

Link found between increased crops and deforestation in Amazon, but issue not so cut and dry
A Kansas State University geographer is part of a research team out to prove what environmental scientists have suspected for years: Increasing the production of soybean and biofuel crops in Brazil increases deforestation in the Amazon. Although this cause-and-effect finding seems fairly straightforward, the issue of deforestation in the Amazon is more complex and more devastating than previously believed. (2011-07-14)

A large number of hardcover titles are being converted to paperback for inclusion and will be available via POD. (2009-12-01)

Amazon basin deforestation could disrupt distant rainforest by remote climate connection
The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions. (2017-06-26)

Scientists reconstruct pre-Columbian human effects on the Amazon Basin
Small, shifting human populations existed in the Amazon before the arrival of Europeans, with little long-term effect on the forest. That's the result of research led by Crystal McMichael and Mark Bush of the Florida Institute of Technology (FIT). The finding overturns the idea the Amazon was a cultural parkland in pre-Columbian times with large human populations that transformed vast tracts of the landscape. (2012-06-18)

Deforested areas of the Amazon Basin have a limited ability to grow new trees because of changes in climate, according to a study. (2017-11-15)

Amazonian Indigenous territories are crucial for conservation
A new study from the University of Helsinki shows that Indigenous territories represent around 45% of all the remaining wilderness areas in the Amazon, comprising an area of three times the surface of Germany. At a time when the Amazon forests face unprecedented pressures, overcoming divergences and aligning the goals of wilderness defenders and Indigenous peoples is paramount to avoid further environmental degradation.

More extreme weather projected in the Amazon could have global climate consequences
A new paper co-authored by WHRC scientists Philip Duffy and Paulo Brando evaluates the accuracy of current climate models and uses them to project future drought and wet periods in the Amazon. They conclude that the whole of the Amazon will confront more hydrological extremes, and that most of the region will experience much more frequent and extensive drought. These changes would have profound implications for forest structure, composition, biomass, and carbon emissions. (2015-10-12)

Droughts in the Amazon rainforest can be predicted up to 18 months in advance
For the first time, it is possible to accurately predict severe drought up to 18 months in advance in Tropical South America. Early warnings of upcoming droughts are imperative for mitigating the impact on millions of people depending on the Amazon rainforest ecosystem. Additionally, droughts threaten the delicate ecosystems of the rainforest in South America. (2020-09-17)

OU-led study shows improved estimates of Brazilian Amazon gains and losses
A University of Oklahoma-led study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate and other human activities have resulted in substantial deforestation in the Brazilian Amazon over the past several decades. (2019-07-29)

Northeastern researchers find that Amazon might not always be pitching you the best prices
A team led by Northeastern University's Christo Wilson shows that Amazon is much more likely to point buyers to sellers who use an automated practice called algorithmic pricing, even though those sellers' prices may be higher than others'. (2016-06-02)

Dust to gust
More than half of the dust needed for fertilizing the Brazilian rainforest is supplied by a valley in northern Chad, according to an international research team headed by Dr. Ilan Koren of the Institute's Environmental Sciences and Energy Research Department. In a study published recently in Environmental Research Letters, the scientists have explained how the Bodélé valley's unique features might be responsible for making it such a major dust provider. (2006-12-28)
