This document summarizes research being conducted in Babati, Tanzania on sustainable intensification of maize-based cropping systems. The research is led by various institutions (IITA, ILRI, CIMMYT, etc.) and has the following objectives: 1) Identify biophysical and socioeconomic constraints to crop and livestock production; 2) Introduce and evaluate improved crop varieties; and 3) Develop postharvest technologies to reduce losses. The status of research deliverables is provided, showing preliminary results on crop yields, variety selection, fertilizer response, and mycotoxin contamination. Lessons learned are discussed, along with proposed research opportunities for 2013/14, such as addressing low yields, maize lethal
