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 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 spatio-temporal drought analysis for the Midwestern US
15 Jun 2009 | Publications | Contributor(s): Rao S Govindaraju, Dev Niyogi
Droughts are prolonged abnormalities of moisture deficits that vary widely across temporal and spatial scales. Many hydrometeorologic variables are used to monitor the status of a drought. However, because of the dependence structure between all affecting variables under various temporal windows,...
A Web-Based Interface for SWAT Modeling on the TeraGrid
06 Jun 2011 | Publications | Contributor(s): Lan Zhao, Carol Song, Indrajeet Chaubey, Rao S Govindaraju
The Soil and Water Assessment Tool (SWAT) is a river basin scale model developed by the USDA Agricultural Research Service (ARS). It is widely used by researchers in various scientific domains to study the impact of land management practices on water quantity, sediment, and water quality in large...
Achieving Sustainable Irrigation Water Withdrawals: Global Impacts on Food Production and Land Use
27 Sep 2017 | Publications | Contributor(s): Jing Liu, Tom Hertel, Richard Lammers, Alexander A Prusevich, Uris Lantz C Baldos, Danielle Grogan, Steve Frolking
Unsustainable water use challenges the capacity of water resources to ensure food security and continued growth of the economy. Adaptation policies targeting future water security can easily overlook its interaction with other sustainability metrics and unanticipated local responses to the...

Analyzing Water Scarcity in Global CGE Models
08 Sep 2017 | Publications | Contributor(s): Jing Liu, Tom Hertel, Farzad Taheripour
Incorporating water into a computable general equilibrium (CGE) model operating at global scale can be extremely demanding due to the absence of standardized data, the sheer dimensions caused by intersecting river basins with countries, and difficulties to model demand for and supply of water....

Debunking the 'New Normal': Why World Food Prices are Expected to Resume their Long run Downward Trend
08 Sep 2017 | Publications | Contributor(s): Uris Lantz C Baldos, Tom Hertel
Contrary to the opinions expressed by many commentators, the recent episode of higher prices for agricultural commodities is likely a transitory phenomenon. When compared to the last half-century, population growth is expected to be much slower in the coming decades, with nearly all of the growth...
