||This report has been prepared to provide as complete a picture as possible of what the Puebla Project is, the nature of the joint effort of those participating, and the social and economic implications of the progress achieved up to now. The project had its origins in- the concern of various CIMMYT staff for the need to develop a methodology for bringing about rapid yield increases among farmers currently producing near subsistence levels. As the project developed, it put down solid roots among farmers and in all of the participating organizations - listed on the previous page. The Puebla Project could not have achieved the success it has without the firm support of the highest authorities of the Mexican Government. The Ministry of Agriculture has given strong backing at both the federal and state levels. The Government of the State of Puebla, where the Project is located, views it as an effective means for beginning an economic and social transformation of the area. The backing given by high governmental authorities and private enterprises has made it possible to improve credit facilities and to make' more readily available the essential inputs and services. The Chapingo Graduate College, through its Departments of Statistics, Agricultural Communications and Genetics, is providing advice and direct service. The National Institute of Agricultural Research, through its Maize Department, has provided genetic materials for developing new high yielding varieties for the area. The CIMMYT provides technical advice and direct assistance through its Departments of Maize, Soils and Communications. lt also provides an administrative structure with a minimum of the bureaucratic impediments which could restrict the functioning of the Project. The Rockefeller Foundation made the initial grant for the Project and has continued its financial support for the technical aspects of the program - coordination, research, extension, and evaluation.
