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...

A seasonal-scale climatological analysis correlating spring tornadic activity with antecedent fall–winter drought in the southeastern United States

14 Jun 2011 | Publications | Contributor(s): Dev Niyogi

Using rain gauge and satellite-based rainfall climatologies and the NOAA Storm PredictionCenter tornado database (1952–2007), this study found a statistically significant tendency forfall–winter drought conditions to be correlated with below-normal tornado days the followingspring in north...

A copula-based joint deficit index for droughts

31 Mar 2010 | Publications | Contributor(s): Rao S Govindaraju

Current drought information is based on indices that do not capture the joint behaviors of hydrologic variables. To address this limitation, the potential of copulas in characterizing droughts from multiplevariables is explored in this study. Starting from the standardized index (SI) algorithm, a...

A spatio-temporal drought analysis for the Midwestern US
