Challenges at the Agriculture-Water-Climate Nexus in the Mississippi River Basin 


To meet the food requirement and improve river health across this basin, it is important to enhance our understanding of agroecosystem responses (including crop production and environmental consequences) to those multiple global changes. We improved the agroecosystem modeling approach to address interactions and feedbacks at the land (agroecosystem)-atmosphere-ocean interfaces. We are applying the improved agroecosystem model to quantitatively assesse the variations of crop production, greenhouse gas fluxes and carbon/nitrogen leaching in the Mississippi River basin, one of the most productive and intensive agricultural regions in the world.
