China’s carbon sinks from land-use change underestimated

The size and attribution of the regional net carbon flux from land-use change (LUC) activities (ELUC) are often highly debated, especially in regions such as China, which has experienced decades-long extensive reforestation activities. Here, using a LUC dataset incorporating remote-sensing and national forest inventory data with two modelling approaches, we show that ELUC in China shifted from a carbon source to a sink in the 1990s, contributing…
