Global patterns in human consumption of net primary production
The uneven footprint of human consumption and related environmental impacts are revealed, the degree to which human populations depend on net primary production ‘imports’ is indicated and policy options for slowing future growth are suggested.
Methane Leaks from North American Natural Gas Systems
Methane emissions from U.S. and Canadian natural gas systems appear larger than official estimates, and global atmospheric CH4 concentrations are on the rise, with the causes still poorly understood.
Quantifying the effect of oxidation on landfill methane emissions
Field, laboratory, and computer modeling methods were utilized to quantitatively assess the capability of aerobic microorganisms to oxidize landfill-derived methane (CH4) in cover soils. The
Nitrous oxide emissions from municipal wastewater treatment.
Nitrous oxide (N 2 0) emissions from primary and secondary wastewater treatment processes were measured during spring and summer 1993 in Durham, NH. The most significant emissions occurred during
Model estimates of nitrous oxide emissions from agricultural lands in the United States
The Denitrification-Decomposition (DNDC) model was used to elucidate the role of climate, soil properties, and farming practices in determining spatial and temporal variations in the production and
Biomass‐burning emissions and associated haze layers over Amazonia
Biomass-burning plumes and haze layers were observed during the ABLE 2A flights in July/August 1985 over the central Amazon Basin. The haze layers occurred at altitudes between 1000 and 4000 m and
Modeling carbon biogeochemistry in agricultural soils
An existing model of C and N dynamics in soils was supplemented with a plant growth submodel and cropping practice routines (fertilization, irrigation, tillage, crop rotation, and manure amendments)
Methane emissions along a salt marsh salinity gradient
The seasonal flux of methane to the atmosphere was measured at three salt marsh sites along a tidal creek. Average soil salinities at the sites ranged from 5 to 17 ppt and fluxes ranged from below
Landfill methane emissions measured by enclosure and atmospheric tracer methods
Methane (CH4) emissions were measured from the Nashua, New Hampshire municipal landfill using static enclosure and atmospheric tracer methods. The spatial variability of emissions was also examined
