Abstract

Bastin (Reports, 12 May 2017, p. 635) claim to have discovered 467 million hectares of new dryland forest. We would argue that these additional areas are not completely "new" and that some have been reported before. A second shortcoming is that not all sources of uncertainty are considered; the uncertainty could be much higher than the reported value of 3.5%.

摘要

巴斯廷（报道，2017 年 5 月 12 日，第 635 页）声称发现了 4.67 亿公顷新旱地森林。我们认为，这些额外的区域并非完全“新的”，有些之前已被报道过。第二个缺点是，并非所有不确定性来源都被考虑在内；不确定性可能比报告的 3.5% 值高得多。
