An article recently published in Science, entitled “The global tree restoration potential”, presents what it calls “the most effective solution at our disposal to mitigate climate change”. The lead author is Jean-François Bastin, an ecologist affiliated with the Swiss Federal Institute of Technology (ETH Zurich).
The article attracted enormous media attention. It reports the results of a study in which Bastin and collaborators used remote sensing and modeling techniques to estimate that forest restoration in areas totaling 900 million hectares worldwide could store 205 gigatonnes of carbon.
The study was contested by a large international group of ecologists led by Joseph Veldman, a professor in Texas A&M University’s Department of Ecosystem Science and Management (USA). At the invitation of the editors of Science, the group formulated a reply, now featuring on the October 18th edition of Science under the title “Comment on ‘The global tree restoration potential’.”
Its authors include William Bond, Emeritus Professor in the University of Cape Town’s Department of Biological Sciences (South Africa) and considered the world’s foremost expert on savanna ecology. Several Brazilian researchers also co-authored the reply, such as Giselda Durigan, affiliated with the São Paulo State Forestry Institute’s Ecology and Hydrology Laboratory.
