Re-Growing Our Lost Tropical Forests

Scientists have concluded that tropical forests demonstrate high resilience, even after they are cut down, due to agriculture or pasture use, if they are left alone for 20 years.  According to the study published in December 2021. 

“Tropical forests are converted at alarming rates to other land uses yet they also have the potential to regrow naturally on abandoned agricultural fields and pastures. Widespread land abandonment because of fertility loss, migration, or alternative livelihood options has led to a rapid increase in the extent of regrowing forests. Currently, regrowth covers as much as 28% (2.4 million km2) of the neotropics alone. Regrowing secondary forests form a large and important component of human-modified tropical landscapes and have the potential to play a key role in biodiversity conservation, climate change mitigation, and landscape restoration.
