Abstract

Fires are increasing in Amazonia, transforming C storage. The evaluation of fire effects has traditionally focussed on aboveground C. However, soil organic carbon (SOC) can store half of total tropical forest C 19 and the impact of fire on existing SOC and the fate of new charcoal (pyrogenic C; PyC) is unknown. SOC loss, transformation and gain may have important implications for the C balance of large areas recovering from recent burning or following cycles of slash and burn agriculture, thereby altering the rate of C loss under a warming climate. This project will implement a systematic pan-Amazonian analysis of the response of SOC to recent fire, drought, and climate warming via a robust chronosequence approach, integrated with innovative modelling to inform land management strategies and C budgets.
