The purpose of this line of research was to understand the role of agriculture in development, and how to achieve economic growth that benefits poor people in the most impoverished regions. To this end, and with support from BMZ and in partnership with the University of Hohenheim, IFPRI built regionalized economic models for Ghana and Viet Nam to evaluate the effectiveness of various development strategies. The work also involved training Ghanaian and Vietnamese collaborators on economy-wide modeling, and coordinating outreach and dissemination of results at the national and international levels.
