Operation Mercury successfully halted most illegal gold mining activity in La Pampa, Peru, reducing deforestation and water quality issues. However, spillover effects led to increased mining in legal areas, highlighting the need for stronger regulations to mitigate environmental harm.
Deforestation contributes to climate change, producing 6-17% of global greenhouse gas emissions. New satellite-based technology tracks forest change globally, enabling policymakers to understand the problem and develop solutions.
A study published in Science found that overestimations of forest preservation in voluntary REDD+ projects result in the generation of millions of worthless carbon credits. The research team calculated that only 6% of these credits are linked to actual reductions in carbon emissions.
Deforestation in Brazilian Amazon's Indigenous Territories led to the emission of 96 million metric tons of carbon dioxide between 2013 and 2021. The rate of deforestation increased by 129% between 2013 and 2021, with 59% of emissions occurring between 2019 and 2021.
A study of tropical tree species found that older, slower-growing trees accumulate more somatic mutations, which can be transmitted to seeds, increasing genetic variation and adaptation. The rate of mutations per year is similar between the two species, suggesting a clock-like accumulation of mutations with age.
A global study found that while recovering tropical forests can remove significant amounts of carbon, the rate of regrowth is outpacing natural recovery. The study highlights the importance of sustainably managing forest areas that can recover from human disturbances.
Research reveals a clear link between tropical forest loss and reduced rainfall, with potential consequences for agriculture, hydropower plants, and local communities. The study estimates that continued deforestation in the Congo could lead to a 8-12% reduction in rainfall by the end of the century.
Almost one quarter of Sweden's last unprotected old-growth forest was logged between 2003 and 2019. Rare ecosystems with rich biodiversity are being lost at a rate of 1.4% per year, posing significant threats to biodiversity and planetary stability.
Researchers found that protected Indigenous lands have higher forest integrity than non-protected areas in all regions analyzed, including the Americas and Africa. However, within Indigenous lands without overlap with protected areas, forest health was actually worse off than non-protected areas.
A new study found that over a 5-year period, millions of cattle spent part of their lives grazing in protected areas of the Brazilian Amazon, including indigenous lands. This undermines efforts to conserve forests and biodiversity in these regions.
Research from German Centre for Integrative Biodiversity Research finds poorly defined land rights increase deforestation in Brazil. Private land rights can be effective if combined with strict environmental policies, such as the Forest Code.
Researchers used satellite imagery and machine learning to pinpoint high-priority areas for deforestation action, reducing the target area by 160,000 km². The study reveals that only 37% of the last three years' deforestation rate was covered by official monitoring in the 11 municipalities.
A study comparing Ohio nature reserves and high-input agricultural lands found that nature reserves can store significantly more carbon. The researchers analyzed soil organic carbon storage, quality, and lability in these two types of land uses.
A new study found that the global forest area per capita has declined by over 60% from 1960 to 2019, due to 81.7 million hectares of loss. This decline threatens biodiversity and affects the lives of 1.6 billion people worldwide.
Deforestation in Indigenous lands, particularly in Apyterewa Territory, poses a significant threat to Brazil's ability to meet its international climate change mitigation targets. The Brazilian government must take effective action to enforce environmental laws and protect the Amazon region.
A new study by the Smithsonian Tropical Research Institute reduces uncertainty in predicting carbon dioxide release from deforestation scenarios. It highlights the capacity of young, regenerating or secondary forests to pull greenhouse gas from the atmosphere, suggesting that these forests can store up to 15% of Panama's national carbo...
A recent study found that protected areas reduce the rate of deforestation by 41%, but nearly one-third of these areas are under intense human pressure. The study suggests that just 6.5% of the Earth's woodlands are truly protected, well below the UN's 2020 target of 17%.
Research reveals that degradation of the Brazilian Amazon forest has surpassed deforestation in terms of area affected. The study found that between 1992 and 2014, degraded forest cover increased by 29,116 square kilometers compared to the 308,311 square kilometers lost to deforestation.
A US$250 million dollar agreement between Norway and Guyana reduced deforestation in Guyana by over 30 percent during the project period. However, deforestation increased immediately after the agreement ended, raising concerns about the long-term effectiveness of REDD+ programs.
A new study predicts that continued deforestation in the Amazon could lead to annual rainfall of less than drought years by 2050. Deforestation rates would need to revert back to pre-2004 levels to achieve this decline, according to researchers.
A study reveals that Amazonian agrarian settlements are responsible for 13.5% of all deforestation in the region, with forest cover declining by 43.5%. Poor coordination between government agencies exacerbates conflicts between environmental and development policies.
Researchers analyzed 143 billion pixels in 654,000 Landsat images to compile maps of forest loss and gain between 2000 and 2012. During this period, 888,000 square miles of forest were lost, while 309,000 square miles regrew.
A new scientific organization is proposed to utilize satellite images to monitor the world's forests and track changes in deforestation rates. Currently, only half of tropical countries have conducted two recent forest surveys needed to construct a deforestation trend.
Purdue University researchers have proposed a way to incorporate deforestation into the international climate change treaty, titled Preservation Pathway. This approach would provide carbon credits for developing countries that set aside existing forests and slow deforestation rates.
Halving deforestation rates by mid-century could prevent one billion tons of carbon from being transferred to the atmosphere through deforestation. Brazil has demonstrated that it is feasible to reduce greenhouse gas emissions from tropical deforestation, with nearly half its deforestation rates cut in recent years.
