How much carbon does slash-and-burn release?
about 200 to 500 million tonnesThey calculated that torching the Atlantic Forest released about 200 to 500 million tonnes of black carbon. Given the material’s half-life, they estimate that it will take between 630 and 2200 years for just half of the black carbon to leach out of the region’s soils.
