Blue and green: Modeling rain-fed and irrigated agriculture on the landscape.
Presented by: Sarah Goslee, USDA-ARS PSWMRU, University Park, PA

The site potential for such sustainable intensification depends on climate, soils, and socio-economic factors. Current crop distributions may provide some insight into future possibilities. Daily weather data and USDA Census of Agriculture data were used to characterize the climatic envelopes for irrigated and rain-fed distributions of several major crops. The locations where rain-fed agriculture is highly productive will shift, in some cases moving away from the areas of most productive soils. Increased irrigation could compensate in some cases, but water availability concerns may make increased irrigation infeasible. Shifting climate, soil fertility patterns, and water availability all must be taken into account when considering the future of US agriculture.

Sarah Goslee is a landscape ecologist with a deep interest in plant species distributions and community assembly. She earned her PhD from the Nicholas School of the Environment at Duke University. She joined the USDA Agricultural Research Service as a postdoc at the Jornada Experimental Range in New Mexico, and moved to the Pasture Systems and Watershed Management Research Unit in 2002. Her work combines greenhouse and field studies with computational ecology.

Join us in person on Tuesday, February 13, 2018 at 12:00 PM in room 102 Forest Resources Building or online using Zoom.
