Title: “The connection between agriculture and greenhouse gas emissions? A river runs through it.”
Abstract: Rapid land use change via agriculture represents an unprecedented human intervention on the earth’s terrestrial landscape and human activity has doubled the amount of reactive nitrogen (N) in the biosphere, resulting in the transport of excess N to nearby rivers. However, streams and rivers are not solely transporters of excess N – they serve as “hotspots” for the transformation of fertilizer-based N to gaseous compounds, including the potent greenhouse gas nitrous oxide (N2O). This talk describes the production of N2O by stream networks and what may be done on the landscape to prevent excess greenhouse gas emissions from our natural waterways.
