Agriculture presents a trilemma. On the one hand, increased food production per capita over the last few decades has lifted millions of people out of starvation. On the other hand, agriculture is a major driver of global environmental change. Balancing the tradeoffs between the need to increase agricultural production (for both food and fuel) while minimizing its environmental impacts is a major challenge of the 21st century. Furthermore, the recent global commodity crisis underscored the vulnerability of the global food system to shocks from extreme weather events, energy markets, and obstruction of the smooth functioning of commodity markets via export bans and other measures designed to force instability onto global markets. We have learned that a “perfect storm” in which all these factors coincide can have a devastating impact on the world’s poor. As we look ahead several decades, will such commodity price spikes become more commonplace in the future? What investments and policies need to be put in place to mitigate the frequency, intensity and/or impacts of such events? In order to answer these questions, improved data base infrastructure is needed in order to support state-of-the-art, spatially explicit modeling of land use, agricultural production, land cover change, and greenhouse gas emissions from these activities.
