Farmers and agricultural policymakers frequently encounter tough decisions with complex trade-offs. Selecting which crop to plant next season, for example, would be much easier with a crystal ball.

Xiong uses modeling tools to simulate how agricultural systems would respond to different policies, technological innovations and climate change.
