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.

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.

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.
