Big changes in agriculture are visible on the global scale – changes in crop yields, dietary choices, water use, fertilizer application, soil retention, and nutrient pollution. In some parts of the world, yield lags, revealing opportunities to get more out of land already in production. In others, crop production has sagged or plateaued. Will yields keep increasing as they have in the past? It’s hard to see trajectories without local context, said session organizer Kate Brauman of the University of Minnesota’s Institute on the Environment. Site-specific field work fills in details.

“Agronomy has been working very successfully for a long time, and it’s been focused on practitioners,” said Brauman. “And global analysis can be hard for someone in the field to interpret. How can we take insights from the local to the global scale and make them useful?”

Ecology has great scientists studying the very local, applied art and science of getting more yield out of our crops and the local ecological effects of agriculture, and great scientists studying global trends, said Bauman. It does not have much of a history of cross-pollination between the groups. This session aims to bridge gulfs of scientific culture and of scale, connecting the satellite’s eye view of global change to the view from the field; computational modeling to on-the-ground experimentation; and snapshot observations to daily, seasonal, annual, and decadal change.
