Brazil’s Amazonian forest carbon: the key to Southern ...

11-07-2016 · Southern Amazonia is the first region of Brazil’s Amazon area to be exposed to intensive conversion to agriculture and ranching. This conversion emits greenhouse gases from the carbon stock in the biomass and soils of the previous vegetation. Quantifying these carbon stocks is the first step in quantifying the impact on global warming from this conversion.

The large carbon stocks of Amazonian forests have been recognized for many years [1] and estimates of total Ama-zonian above-ground biomass (AGB) for terra firme (dry land) forest, based on forest census data and remote sensing range from 58 to 134 Pg C [2–8]. However, there is another significant store of carbon in Amazonia which has not, to

Deforestation and Carbon Loss in Southwest Amazonia ...

16-05-2017 · In 2012 Brazil’s National Congress altered the country’s Forest Code, decreasing various environmental protections in the set of regulations governing forests. This suggests consequences in increased deforestation and emissions of greenhouse gases and in decreased protection of fragile ecosystems. To ascertain the effects, a simulation was run to the year 2025 for the municipality …

Amazon Deforestation Is Causing 20% of Forests to …

12-02-2020 · An extensive study that looked at a decade of carbon emissions found that nearly 20 percent of one of the world's largest carbon sinks is actually releasing carbon instead of capturing it. The study measured carbon by flying airplanes equipped with carbon sensors over various parts of the forest every two weeks.

How green can Amazon hydropower be? Net carbon …

25-06-2021 · The current resurgence of hydropower expansion toward tropical areas has been largely based on run-of-the-river (ROR) dams, which are claimed to have lower environmental impacts due to their smaller reservoirs. The Belo Monte dam was built in Eastern Amazonia and holds the largest installed capacity among ROR power plants worldwide.

Carbon uptake by mature Amazon forests has mitigated ...

15-02-2017 · Several independent lines of evidence suggest that Amazon forests have provided a significant carbon sink service, and also that the Amazon carbon sink in intact, mature forests may now be threatened as a result of different processes. There has however been no work done to quantify non-land-use-change forest carbon fluxes on a national basis within Amazonia, or to place these national …
