USDA report provides uniform ways of measuring greenhouse gas emissions

The US Department of Agriculture has released a report that for the first time provides uniform scientific methods for quantifying the changes in greenhouse gas emissions and carbon storage from various land management and conservation activities.

A media statement from Colorado State University says its faculty members served as authors and external science advisors on the new report and a CSU team is leading the implementation of a new online tool that provides customized GHG reports and management plans in accordance with the new guidelines.

The report is titled Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory. It is expected to help the USDA evaluate greenhouse gas mitigation programmes and develop new tools to help farmers, ranchers and forest landowners participate in emerging carbon markets.

Research in US clarifies the health costs of air pollution from agriculture

Ammonia pollution from agricultural sources poses larger health costs than previously estimated, according to NASA-funded research.

Harvard University researchers Fabien Paulot and Daniel Jacob used computer models, including a NASA model of chemical reactions in the atmosphere, to better represent how ammonia interacts in the atmosphere to form harmful particulate matter.

The improved simulation helped the scientists narrow in on the estimated health costs from air pollution associated with food produced for export – a growing sector of agriculture and a source of trade surplus.
