A copula-based joint deficit index for droughts
31 Mar 2010 | 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 review of global-local-global linkages in economic land-use/cover change models
04 May 2019 | Contributor(s): Tom Hertel, Thales A P West, Jan Börner, Nelson Benjamin Villoria
Global change drivers of land-use/cover change (LUCC) like population dynamics, economic development, and climate change are increasingly important to local sustainability studies, and can only be properly analyzed at fine-scales that capture local biophysical and socio-economic conditions. When...

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,...

Energy prices will play an important role in determining global land use in the twenty first century
31 Jul 2014 | Publications | Contributor(s): Jevgenijs Steinbuks, Tom Hertel
Global land use research to date has focused on quantifying uncertainty effects of three major drivers affecting competition for land: the uncertainty in energy and climate policies affecting competition between food and biofuels, the uncertainty of climate impacts on agriculture and forestry,...
