Andean Soil Carbon: The Deep Pool, Still Uncredited

A new policy brief distils our Global Change Biology study of 36 plots across the Colombian Andes: soil carbon rises six-fold from lowland to high-elevation forest, and a fire-derived fraction nine times the Amazon average makes it exceptionally durable — yet carbon-credit standards still treat soil as optional.

Amazon Soil Carbon: The Missing Credit

Amazon Soil Carbon: Policy Brief Summary The conversion of forest to agriculture in the Amazon triggers a “deforestation multiplier”: the ecosystem loses carbon equivalent to about 1.2 times the original forest’s aboveground biomass. Current carbon-credit standards such as Verra’s Verified Carbon Standard (VCS) focus on standing timber, yet new evidence highlights the significant, unprotected carbon […]

High-elevation tropical forest soils in Colombian Andes store nine times more pyrogenic carbon than Amazonian forests

Soil carbon loss twice as severe with conversion to agriculture than with repeated wildfire in Amazonian forests

A new study shows the significant impact of recurring fires and agricultural conversion on soil carbon storage in the Amazon rainforest. The research, a collaboration between the University of Exeter (UoE) and Center for Nuclear Energy in Agriculture (CENA) at the University of São Paulo (USP), demonstrates substantial carbon loss and degradation of soil properties […]

Does fire in forests regrowing on old pastures reduce soil carbon? Fieldwork in central Amazonia

The Amazon rainforest, an important carbon sink, faces increasing threats from deforestation and wildfires. But what happens to the soil carbon after these disturbances? MSc student, Lorena Fleury, in the Tropical Forest Science Postgraduate Programme at the National Institute for Research in Amazonia (INPA), supervised by Prof. Ted Feldpausch, has been sampling soil in secondary […]

Extreme El Niño weather saw South America’s forest carbon sink switch off

Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact […]

Ancient fires enhance Amazon forest drought resistance

In our recent paper, “Ancient fires enhance Amazon forest drought resistance” published in Frontiers in Forests and Global Change, we studied if ancient fires can alter the response of Amazonian forests to drought events.

Fires from 2015 El Niño drought burned “fire-resistant” wet forests in central Amazonia

A new study by Pontes-Lopes et al. 2021 examining the impacts of the record-breaking drought and fires caused by the 2015/2016 El Niño has found that even the wet forests of central Amazonia, forests considered relatively fire-resistant, were affected by fire.

Scientists unravel how and why Amazon trees die

A huge new study has unravelled what factors control tree mortality rates in Amazon forests and helps to explain why tree mortality is increasing across the Amazon basin. The capacity of the Amazon forest to store carbon in a changing climate will ultimately be determined by how fast trees die. The new analysis found that the […]

Competition influences tree growth, but not mortality, in Amazonia and tropical Africa forests

Competition among trees is an important driver of community structure and dynamics in tropical forests. Neighboring trees may impact an individual tree’s growth rate and probability of mortality, but large-scale geographic and environmental variation in these competitive effects has yet to be evaluated across the tropical forest biome.

How fire affects young trees and forest regrowth in the southern Amazon

There has been a large increase in deforestation and wildfire in Amazonia over recent years. Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks (Figure 1). Remote sensing now permits a rapid and accurate assessment of the location and extent of fires. On the ground and in forests, however, there […]

Better IPCC estimates of how fast regrowing tropical forests store carbon

Previous research (Feldpausch et al. 2007) by my group showed the variation in rates of carbon uptake by regrowing secondary forests. Our new research published this month refines IPCC default rates used to estimate aboveground net biomass change for tropical and subtropical forest. The results will improve estimates of forest carbon uptake for greenhouse gas accounting.
