Agricultural systems are tasked with producing more food, fiber, and fuel for a growing population, supporting livelihoods and development, and decreasing environmental impacts. Agroecology informs pathways to address these coupled challenges by improving our understanding of global environmental change and its impacts, developing approaches to increase resilience and adapt to change, and revealing tradeoffs with varied management practices. Understanding the coupling between abiotic and biotic systems is critically important in a world with rapid environmental change, and this session will predominantly focus on connections between the physical environment and agroecosystems across the world. We bring together a diverse array of scholars working to understand these connections using a combination of field studies, models, and data synthesis. Primary topics include climate change and variability, agricultural water use in a changing climate, nutrient cycling in temperate and tropical agroecosystems, greenhouse gas emissions from global agriculture, and the tradeoffs between organic and conventional management practices.
