According to a new study, the regrowth of Amazon might be significantly slower than we previously thought. The researchers studied the regrowth of Amazon following natural disaster over 20 years and found that the global climate change might be having significant impact on the regrowth of Amazon.
The researchers revealed that secondary forests are crucial on combating climate change due to their impact on reducing carbon dioxide from the atmosphere. However, the latest research has shown that only secondary forests held on 40 percent of the carbon that were not disrupted by human interactions. As a result, it might take over 100 years for the forests to completely recover.
Moreover, the researchers found that the biodiversity is depleting due to ongoing climate change. For instance, the biodiversity levels within the secondary forests with local undisturbed forests were only at 56 percent, with no increase in species diversity in the last 20 years.
In order to combat the ongoing climate changes and their effects on forests, countries around the world have taken initiatives to reduce the consequences. Recently Brazil has initiated its target to restore 12 million hectares of forest under the Paris Climate Agreement. The researchers recommended that climate agreements will need to take stance against deforestation of primary forest if the agreements are to yield significant results in the coming years.
