Future Directions and Potential Collaboration • Improved estimates of downscaled climate projections and the challenges of differing spatial and temporal scales on system modeling efforts • Estimation of agricultural production potential and food security under changing climate • Investigation of the of frequency, magnitude, and impact of climate extremes • Quantification of uncertainty associated with impact assessment and management of climate-related risk • Identification of potential new adaptation strategies
