Agricultural Diversity
Today, over a third of global ice-free land is devoted to agricultural production. These agricultural landscapes are increasingly simplified and intensively managed. This project examines the role of diversification–of crops, but also of people and practices–in boosting agricultural production, ecological integrity, and agricultural resilience. This project is funded by USDA NIFA Grant 2020-67019-31157.
