Journal ArticleDOI
Reducing greenhouse gas emissions of Amazon hydropower with strategic dam planning.

TL;DR: The authors estimate the range of GHG emission intensities expected for 351 proposed and 158 existing Amazon dams and find that existing Amazon hydropower reservoirs collectively emit 14 Tg CO2eq per year, and that if all proposed Amazon dams are built, annual emissions would increase 5-fold.
Journal ArticleDOI
Variability of carbon dioxide flux from tropical (Cerrado) hydroelectric reservoirs
Fábio Roland,Luciana O. Vidal,F. S. Pacheco,Nathan Barros,Arcilan Trevenzoli Assireu,Jean Pierre Henry Balbaud Ometto,André C. P. Cimbleris,Jonathan J. Cole +7 more
TL;DR: It is demonstrated that the reservoirs in the Brazilian Cerrado have low rates of CO2 emissions compared to existing global comparisons, and it is suggested that ignoring the spatial variability can lead to more than 25% error in total system gas flux.
Journal ArticleDOI
Estimating greenhouse gas emissions from future Amazonian hydroelectric reservoirs
Felipe A.M. de Faria,Paulina Jaramillo,Henrique O. Sawakuchi,Jeffrey E. Richey,Nathan Barros +4 more
TL;DR: In this article, two different approaches are presented to investigate the future carbon balance of eighteen new reservoirs in the Amazon basin, based on a degradation model of flooded carbon stock, while the second approach is based on flux data measured in Amazonian rivers and reservoirs.
Journal ArticleDOI

TL;DR: The results suggest that despite being a primary production and OC burial hotspot, the tropical eutrophic system studied here was a stronger CO2 and CH4 source than a C sink, mainly because of high rates of OC mineralization in the water column and sediments.
