Greenhouse gases in intensive agriculture: contributions of individual gases to the radiative forcing of the atmosphere

Agriculture plays a major role in the global fluxes of the greenhouse gases carbon dioxide, nitrous oxide, and methane. From 1991 to 1999, we measured gas fluxes and other sources of global warming potential (GWP) in cropped and nearby unmanaged ecosystems. Net GWP (grams of carbon dioxide equivalents per square meter per year) ranged from 110 in our conventional tillage systems to -211 in earl...

Mitigation of Greenhouse Gas Emissions in Animal Agriculture

Livestock and Poultry Environmental Learning Center Animal agriculture contributes about three percent of all anthropogenic (humancaused) greenhouse gas emissions in the U.S. (EPA, 2011). Although this is small relative to other economic sectors such as transportation and energy, animal agriculture is also being called upon to defend its environmental impact and continually demonstrate its comm...

Greenhouse Gases

Examination of research into pole alternatives indicates that, without exception, studies have found that total energy requirements associated with wood materials are considerably lower than those of commonly substituted materials. The substitution of high-energy-intensive materials for low-energy-using wood materials would contribute substantially to an overall increase in carbon

Agricultural Mitigation of Greenhouse Gases: Science and Policy Options

Capturing greenhouse gases.

til very recently, scientists still deliberated whether human activity was altering the global climate. Specifically, was the release of greenhouse gases, which trap heat radiating from the earth’s surface, to blame? With scientific evidence mounting in favor of the affirmative, the discussion is now turning to what steps society can take to protect our climate. One solution almost certainly wi...
