Title: Impact of climate change and changing climate variability on crop production systems in the Midwestern USA Name: Jane Southworth Institution (current): Indiana University Current Location: Bloomington, IN, USA Institution and Location (Jan 2002): University of Florida, Gainesville, FL, USA Yrs experience in modeling: 4 years Keywords: climate change, climate variability, impacts on crop growth Crops: Maize, soybeans, wheat Models: DSSAT suite, HadCM2, PCLP Applications: climate change scenarios, farm-level adaptation strategies Summary: Research project (EPA-STAR) addressing the impacts of potential future changes in climate on midwestern agricultural systems for the 2050s. Modeling crop level impacts of changes in mean future climate conditions, changing climate varaibility, and carbon dioxide fertilization using HadCM2 climate scenarios for maize, wheat and soybeans, using the DSSAT 3.5 suite of models. Research also addresses the potential farm-level adaptations strategies and farm-level impacts using PCLP and risk assessment analyses.
