Activity Description

2001  

  • Emissions of Nitrous Oxide and Nitric Oxide from Soils of Native and Exotic Ecosystems of the Amazon and Cerrado Regions of Brazil"

    This paper, by Davidson, Eric A.; Bustamante, Mercedes M.C.; and de Siqueira Pinto, Alexandre, was published on "The Scientific World Journal, November 2001"

    Synopsis:

    Soils are important sources of atmospheric nitrous oxide and nitric oxide. Conversion of native tropical ecosystems to agriculture may change this source. Studies in the Amazon Basin indicate that some young cattle pastures have higher emissions than forests, but old pastures and secondary forests have lower emissions, thus decreasing Basin-wide emissions slightly. Fewer studies exist for the Cerrado (Brazilian savanna) region, but they also show either decreases or modest increases in emissions from agricultural soils.

Science Questions:

Carbon Dynamics:

        CD-Q3a - How do pools and fluxes of carbon and nutrients (in soils) of pasture/cropland change over time and what factors determine carbon gain or loss?

Nutrient Dynamics and Surface Water Chemistry:

        ND-Q1 - How do stocks, cycling rates and budgets of carbon and important elements nitrogen, phosphorus, potassium, calcium, magnesium, and aluminum change under different land covers and land uses?
        ND-Q4 - How do changes in land use and climate alter the stocks, processes and fluxes of dissolved and particulate organic matter, nutrients, and trace gases from the uplands across the riparian zones and floodplains and down the channels of river corridors?
        ND-Q4a - How will the composition and quantity of nutrients and organic matter entering and being processed within streams be altered under different land-use change scenarios?
        ND-Q4c - To what extent do intact riparian zones buffer streams against changes due to anthropogenic activities in surrounding uplands?

Trace Gas and Aerosol Flux:

        TG-Q1 - How are fluxes of trace gases and aerosols between ecosystems (both upland and wetland) and the atmosphere of Amazônia affected by land cover and land use change?
        TG-Q2 - What is the (climatically driven) seasonal and inter-annual variability of trace gas and aerosol fluxes between the atmosphere and different land use and land cover types?
        TG-Q3 - Are losses and gains of carbon from Amazônian ecosystems in forms other than carbon dioxide (e.g. carbon monoxide, methane, volatile organic carbon, organic aerosol) of sufficient magnitude to influence ecosystem carbon balance?
