The power and pain of market-based carbon policies: a global application to greenhouse gases from ruminant livestock production

08 Sep 2017 | Contributor(s): Benjamin Henderson, Alla A Golub, Daniel Djauhari Pambudi, Tom Hertel, Cecile Godde, Mario Herrero, Oscar Cacho, Pierre J. Gerber

The objectives of this research are to assess the greenhouse gas mitigation potential of carbon policies applied to the ruminant livestock sector [inclusive of the major ruminant species—cattle (Bos Taurus and Bos indicus), sheep (Ovis aries), and goats (Capra hircus)]— with...

Economic impacts of climate change on agriculture: A comparison of process-based and statistical yield models

07 Sep 2017 | Contributor(s): Frances C Moore, Uris Lantz C Baldos, Tom Hertel

A large number of studies have been published examining the implications of climate change for agricultural productivity that, broadly speaking, can be divided into process-based modeling and statistical approaches. Despite a general perception that results from these methods differ...

Metadata for Indiana Stream Flow Data

15 May 2012 | Downloads | Contributor(s): Jake R Carlson

The United States Geological Survey (USGS) daily streamflow dataset is the source of this dataset. Streamflow data are subjected to human interference, and therefore data contain both natural and regulated flows. This practice does not cause serious problems in flood frequency analysis (flows are...
