The global pattern of expanding urban centers and increasing agricultural intensity is leading to more frequent interactions between air pollution …
Despite significant recent public concern and media attention to the environmental impacts of food, few studies in the United States …
As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental …
1. Ammonia (NH3) is an important gaseous pollutant generated from manure in commercial poultry farms and has been an environmental, …
The objectives of the current study were to evaluate the effect of feeding diets containing 0, 10, or 20% distillers …
1. A survey of the concentration and emission rates of aerial ammonia, nitrous oxide, methane, carbon dioxide, dust and endotoxin …
1. Production of total heat, divided into sensible and latent heat, together with carbon dioxide and animal activity were determined …
Environmental effects of economic activities are ultimately driven by consumption, via impacts of the production, use, and waste management phases of products and services ultimately consumed. Integrated product policy (IPP) addressing the life-cycle impacts of products forms an innovative new generation of environmental policy. Yet this policy requires insight into the final consumption expenditures and …
1. In a pen study, NH3 flux estimates were performed when clean wheat straw or wood shavings were used as …
Differences in soil, climate and socioeconomic conditions cause animal production to vary widely between European regions, notably in animal density and percentage landless farming. They have in common that animal products result from the cycling and redistribution of nutrients through soil, air, plants, animals and manure, with energy from photosynthesis or from the input of …
1. Three separate experiments were conducted to determine if the addition of carbohydrate sources directly to freshly-produced laying hen manure …
Poultry production faces increasing environmental challenges, in the United States and globally. Although the environmental impact of poultry production has …
The Ecological Footprint measures the amount of biologically productive land and water area required to support the demands of a …
Food consumption may account for upwards of 15% of U.S. per capita greenhouse gas emissions. Online carbon calculators can help consumers prioritize among dietary behaviors to minimize personal “carbon footprints,” leveraging against emissions-intensive industry practices. We reviewed the fitness of selected carbon calculators for measuring and communicating indirect GHG emissions from food consumption. Calculators were …
Research shows that livestock account for a significant proportion of greenhouse gas (GHG) emissions and global consumption of livestock products is growing rapidly. This paper reviews the life cycle analysis (LCA) approach to quantifying these emissions and argues that, given the dynamic complexity of our food system, it offers a limited understanding of livestock’s GHG …
The environmental assessment of human activities is presently a hot topic. It is not only important from an ecological perspective, …
The reduction of emissions of air pollutants is subject of international conventions, which include reporting of emissions in accordance with …
Anthropogenic warming is caused mainly by emissions of greenhouse gases (GHGs), such as carbon dioxide, methane, and nitrous oxide, with …
