abstract = "The globally important carbon sink of intact, old-growth tropical
humid forests is declining because of climate change,
deforestation and degradation from fire and logging13. Recovering
tropical secondary and degraded forests now cover about 10% of the
tropical forest area4, but how much carbon they accumulate remains
uncertain. Here we quantify the aboveground carbon (AGC) sink of
recovering forests across three main continuous tropical humid
regions: the Amazon, Borneo and Central Africa5,6. On the basis of
satellite data products4,7, our analysis encompasses the
heterogeneous spatial and temporal patterns of growth in degraded
and secondary forests, influenced by key environmental and
anthropogenic drivers. In the first 20 years of recovery, regrowth
rates in Borneo were up to 45% and 58% higher than in Central
Africa and the Amazon, respectively. This is due to variables such
as temperature, water deficit and disturbance regimes. We find
that regrowing degraded and secondary forests accumulated 107 Tg C
year\−1 (90130 Tg C year\−1) between 1984 and 2018,
counterbalancing 26% (2134%) of carbon emissions from humid
tropical forest loss during the same period. Protecting old-growth
forests is therefore a priority. Furthermore, we estimate that
conserving recovering degraded and secondary forests can have a
feasible future carbon sink potential of 53 Tg C year\−1
(4462 Tg C year\−1) across the main tropical regions
studied.",
