Researchers from EPFL and WSL Federal Institute have discovered that converting savannas into oil palm crops, without deforestation, can improve the carbon footprint of these plantations and reduce their environmental impact. The study, published in the journal Global Change Biology, found that using degraded savannas and pastures for oil palm cultivation can lead to a positive carbon balance, as these areas have few trees and do not contribute to deforestation. The research also demonstrated that by optimizing farming practices, more carbon can be sequestered, improving soil fertility and biodiversity. However, the authors stress the importance of prioritizing the conservation of savannas, given their biodiversity value.
